September 2003 Back to Contents Page Wireless LAN Overview: Intel(R) PRO/Wireless 2200BG User's Guide About Wireless LAN Technology l Choosing a WLAN l Configuring a WLAN l Identifying a WLAN l Surveying the Site of Your WLAN l Factors Affecting Range A wireless network connects computers without using network cables. Computers use radio communications to send data between each other. You can communicate directly with other wireless computers, or connect to an existing network through a wireless access point. When you set up your wireless adapter, you select the operating mode for the kind of wireless network you want. You can use your wireless adapter to connect to other similar wireless devices that comply with the 802.11 standard for wireless networking. Choosing a Wireless LAN Wireless LANs can operate with or without access points, depending on the number of users in the network. Infrastructure mode uses access points to allow wireless computers to send and receive information. Wireless computers transmit to the access point, the access point receives the information and rebroadcasts it to other computers. The access point can also connect to a wired network or to the Internet. Multiple access points can work together to provide coverage over a wide area. Peer-to-Peer mode, also called Ad Hoc mode, works without access points and allows wireless computers to send information directly to other wireless computers. Ad Hoc Mode is only supported in 802.11b and 802.11g networks. You can use Peer-to-Peer mode to network computers in a home or small office or to set up a temporary wireless network for a meeting. Configuring a Wireless LAN There are three basic components that must be configured for an 802.11 wireless LAN to operate properly:
l Network Name: Each wireless network uses a unique Network Name to identify the network. This name is called the Service Set Identifier (SSID). When you set up your wireless adapter, you specify the SSID. If you want to connect to an existing network, you must use the name for that network. If you are setting up your own network you can make up your own name and use it on each computer. The name can be up to 32 characters long and contain letters and numbers. l Profiles: When you set up your computer to access a wireless network, the wireless client manager creates a profile for the wireless settings that you specify. If you want to connect to another network, you can scan for existing networks and make a temporary connection, or create a new profile for that network. After you create profiles, your computer will automatically connect when you change locations. l Security: The 802.11 wireless networks use encryption to help protect your data. Wired equivalent privacy (WEP) uses a 64-bit or 128-bit shared encryption key to scramble data. Before a computer transmits data, it scrambles the data using the secret encryption key. The receiving computer uses this same key to unscramble the data. If you are connecting to an existing network, use the encryption key provided by the administrator of the wireless network. If you are setting up your own network you can make up your own key and use it on each computer. m Wi-Fi Protected Access (WPA) is a security enhancement that strongly increases the level of data protection and access control to a WLAN. WPA mode enforces 802.1x authentication and key-exchange to strengthen data encryption. WPA utilizes its Temporal Key Integrity Protocol (TKIP). TKIP provides important data encryption enhancements that include a per-packet key mixing function, a message integrity check (MIC) named "Michael", an extended initialization vector (IV) with sequencing rules, and a also re-keying mechanism. Using these improvement enhancements, TKIP protects against WEP's known weaknesses. m Cisco Client Extention (CCX) is a server and client 802.1x authentication via a user-supplied logon password. When a wireless access point communicates with a Cisco LEAP-enabled RADIUS (Cisco Secure Access Control Server (ACS) server), Cisco LEAP provides access control through mutual authentication between client wireless adapters and the wireless network and provides dynamic, individual user encryption keys to help protect the privacy of transmitted data. Identifying a Wireless Network Depending on the size and components of a wireless LAN, there are many ways to identify a wireless LAN:
l The Network Name or Service Set Identifier (SSID): Identifies a wireless network. All wireless devices on the network must use the same SSID. l Extended Service Set Identifier (ESSID): A special case of SSID used to identify a wireless network that includes access points. l Independent Basic Service Set Identifier (IBSSID): A special case of SSID used to identify a network of wireless computers configured to communicate directly with one another without using an access point. l Basic Service Set Identifier (BSSID): A unique identifier for each wireless device. The BSSID is the Ethernet MAC address of the device. l Broadcast SSID: An access point can respond to computers sending probe packets with the broadcast SSID. If this feature is enabled on the access point, any wireless user can associate with the access point by using a blank (null) SSID. Surveying the Site of Your Wireless LAN Conducting a site survey for your wireless LAN is the most crucial step in the process of setting up a wireless network. It greatly reduces the amount of troubleshooting you will have to do once you have the wireless LAN set up and ready for connection testing. To conduct a site survey, you will need the following tools:
l An access point (or laptop computer) that is set up to be the transmitter. It should be mounted near and at the same height as the designated location of your wireless LAN. l A laptop that will act as the mobile receiver. It must contain your site survey software. l An area or building map, which will be used to plot the strength of your signals. Once you have the tools you need, you are ready to survey the inside of the building. Launch the site survey software on the mobile receiver laptop and carry it around in the intended wireless LAN area to test the signal strength. Be sure to also check the signal strength of each intended access point location. If you encounter problems while surveying the site, make sure your transmitter laptop is not located on a wall containing metal, such as an air-conditioning duct, which will interfere with the range of your signal. Simply move the transmitter and test the signal strength again. For users to have seamless coverage when moving from access point to access point, the signal levels at each point must overlap. There is software available that will seamlessly hand off changing signal levels from one access point to another. Your building's infrastructure can sometimes interfere with the microwave signal, but finding the location and cause of the interference will allow you to figure out the best place to mount your access points for optimal area coverage. Microwave signals travel in all directions, which means there is one access point for a multi-floor building. However, the range is highly dependent on the material used to construct the flooring, especially metal materials. Once your signal strength is strong inside the building, you are ready to check the strength outside the building. To do so, simply carry the mobile receiver laptop as far down the street or around the building as you can go without losing significant signal strength. If possible, you should be aware of the types of networks being used by the companies on the floors above and below you, so that you can work together in harmony. With wireless networks, security is very important and if you communicate with those around you, you are better prepared to select the right channels, as well as the best location for access points. Factors Affecting Range Although access points can transmit signals up to 60 feet away in an area with many walled barriers or as much as 500 feet away in a large open area, the range is affected by the following factors:
l Building materials, such as steel and drywall, can shorten the range of the radio l Physical layout of the area can interfere with the signals and cause them to be signals. dropped. l Electronic noise from cell phones, microwave ovens, or other devices on the same frequency can interfere with the transmission of the signals. l Range is inversely proportional to data rate, so the faster that the signals are sent, the less distance they will travel. Taking these factors into consideration when you survey the site for your WLAN is key to providing all of your users with undisturbed mobile connectivity. Using multiple access points will, of course, reduce the impact of these factors if your area has dividing walls throughout. What is a Site Survey?
A site survey is an in-depth examination and analysis of a proposed wireless LAN site. The purpose of a site survey is to determine the number of access points needed, the types of antennas needed, and the best placement for those access points and antennas. Although the goal of a site survey is simple, the means of arriving at that goal are not. Some of the steps involve taking measurements, but most involve experience, trial and error, and a little guesswork rather than numbers and figures. When to Perform a Site Survey Intel recommends that you perform a site survey prior to installing a wireless LAN. Site surveys are especially important when:
l You are installing a new site: Evaluate the placement of the access points and antennas throughout the proposed site. l You are changing an existing site: When modifying or extending an existing network structure, re-evaluate the placement of the access points and antennas. If you need a different level of coverage in some areas, you may need to move, replace, or supplement access points and antennas. l You are physically changing the site: Remodeling may introduce new sources of interference, such as motors and metal structures within the coverage area of the access point, even if it does not directly effect the sites where the access points are located. Elements of an Effective Site Survey An effective site survey requires four elements. Failure to commit the appropriate time, money, and energy to accomplish a proper site survey in advance may result in greater expenditures of money and time later, when problems arise that require repeated adjustments to the wireless configuration. The three elements of an effective site survey are:
1. Examine the network usage problems solved by the wireless LAN. How many clients need a wireless LAN connection? What areas of the site require wireless LAN connectivity? How many hours each day is wireless LAN connectivity required? Which locations are likely to generate the largest amount of data traffic?
Where is future network expansion most likely?
2. Study blueprints of the proposed wireless LAN site. A site blueprint provides a map of the site as well as the location of objects, such as walls, partitions, and anything else that could affect the performance of a wireless LAN. Examining the site blueprint prior to conducting the physical walk-
through helps you identify areas in which wireless equipment is likely to perform well and areas where it is not. Many obstructions are not readily visible and, in some cases, a room originally built for a specific purpose, such as a radiology lab, might have been converted into something completely different, such as a conference room. The blueprint may also show areas proposed for future building expansion. To prepare for the next step of the site survey, mark possible wireless device locations on the blueprint and refer to the marked blueprint during the physical walk-through and inventory. 3. Conduct a physical walk-through and inventory. The primary purpose of the physical walk-through is to document any items or materials near a proposed device location that may interfere with reception or transmission and affect network performance. Document stock and inventory levels, current environmental conditions and any materials that may interfere with the wireless LAN. Back to Contents Page Please read all restrictions and disclaimers.

To avoid conflicts, Intel(R) PROSet for Wireless has temporarily disabled its Profile Management features" is displayed. Refer to Enabling Intel(R) PROSet for Wireless to manage Your Wireless Connections for information. Using a Profile with an incorrect WEP Encryption Key When connected to an access point using a profile with an incorrect WEP key encryption, the task tray icon and the General page will both indicate good signal strength and that you are associated with the AP. However, when you attempt to send data to the AP using this profile, because of the incorrect WEP key encryption, authentication cannot be established to acquire an IP address from the AP to allow data transfer. Refer to the following WEP encryption and authentication settings. Open Authentication with an incorrect WEP 64 or 128-bit encryption key:
l A profile with an incorrect WEP encryption key will allow the wireless adapter to associate with the access point. l No data transfer Open Authentication with no WEP encryption:
l Allows association to an access point l Data transfer is allowed Shared Authentication:
l Associated to an AP always allows data transfer. Problems with installation Windows does not detect the wireless adapter:
1. Remove and re-install the adapter. 2. Uninstall and reinstall the adapter's drivers. Users are dropped from the wireless network Suggested causes and solutions:
l Find out if a person or workgroup moved or if the building has been rearranged. l If two or more users are seated too close to each other, performance can suffer. Instruct your users to space themselves a small distance apart to keep receivers from being overloaded. l Delivery trucks with very large metal sides can affect performance by reflecting destructive signals back into a building. If you have an installation that includes a shipping dock, check to see if the problem coincides with the arrival of large trucks. l Personal systems can also interfere with your network. Wireless speakers, cordless earphones, some Bluetooth devices, and similar systems can be the source of an infrequent but hard to find the problem. Some systems do not conform to wireless regulations. Shut off suspect devices or remove them from the area. l If possible, remove and reinstall your new software. Conflicts with other resident software packages are always a possibility, and they are not always the fault of the newest addition. Sometimes just starting over fixes the problem. l Swap units around. Does your problem follow the changed units, or is it unique to a specific location? If it follows the product, the swapped unit could be damaged, or improperly configured. If the problem stays with the location, try to find out what is different about that particular room or area. Range decreases as data rate increases This is a normal condition. Range is inversely proportional to data rate: the faster the data, the shorter the range. This has to do with the modulation technology used. Very fast data rates require extremely complex signal waveforms, where even minor distortions can result in data errors. Slower data rates are much more tolerant, and consequently will get through even in the presence of some amount of noise, interference, distortion and echo. Signal doesn't pass through a short or thin wall Range is highly dependent on the physical environment. In a line-of-sight location, with elevated and calibrated antennas, range predictions are quite accurate. This is not true in a typical office building, where the walls may be simple drywall (which is almost transparent to microwaves), or could be plaster with metal underneath. Most sites are somewhere between these two extremes, and consist of a mixture of surfaces. You cant tell what is inside a wall by just looking at it, and we cant tell you exactly what distance you will achieve. Consider published range information to be typical, average, common or usual. Do not expect it to be exact. Signal strength drops when a cell phone is used in the area Range also depends on the electronic environment. If other equipment that could cause interference is nearby, the range of your transceiver could vary widely, and could change suddenly when the other equipment activates. This is particularly true for 802.11b installations, which share their frequencies with microwave ovens, cordless phones, wireless hi-fi speakers, electronics toys and similar devices. Try to keep your system away from other transmitters, and from other sources of electrical noise, such as large motors, spot welders, and similar electronically noisy devices. Range is shorter than it should be Repeat some tests late in the evening, or on a weekend, when there may be less interference. However, some users leave their networks turned all the time so this test is not foolproof. By all means, try more than one channel. Your range problem may just be a nearby user whose system uses your present test channel. Interference from fluorescent lights If you mount an access point close to fluorescent light fixtures, the lamp glow appears constant, but inside the lamp tube, ionization appears and disappears 120 times a second. This can modulate or chop an incoming signal and interfere with reception. When too much range is undesirable Too much range is not necessarily a good thing. At first it would appear that you would want as much range as possible, but with the increase in range comes an increase in interference potential, as your unit hears not only your other units but also manages to hear the systems of other companies up and down the street. If you have a large installation, you will also wind up with more than one access point using the same channel. If a remote unit hears two or more access points, this will slow the network. Help Prevent access to wireless networks from outside the building Excess transmit range presents a special reverse problem. For example, putting an access point adjacent to a second floor bay window invites anyone with the right software on the street below to pick up and enjoy all network transmissions. We discuss some possible solutions to this problem further on. Problems with Network Connectivity If you cannot connect to the wireless network, try the following:
Check Network Settings 1. From the General page, check that the Network Name (SSID) and operating mode are correct. If the laptop is configured for ad hoc networking, make sure that the channel is correct. 2. To correct these settings, click the Networks tab. 3. Select the profile being used. 4. Click the Edit button and make the changes. Check Security Settings 1. From the General page, check that the security settings are correct. 2. To correct the security settings, click the Networks tab. 3. Select the profile being used. 4. Click the Edit button. 5. Click the Security tab. Make sure that the settings for WEP encryption are correct. Checking Adapter Statistics Adapter Statistics If the adapter is communicating with an access point (infrastructure mode) or other computers in peer-to-peer mode, click the Statistics button in the Troubleshooting tab to display the current information about how well the adapter is transmitting and receiving information. Before calling Customer Support Make a note of the following answers before calling customer support:
l From the General tab, view the adapter's connection details. Check that it is associated with an access point, and the quality and strength of the signal. l From the General page, click the Details button and check what revision of software and hardware or other LAN software are you running?
l How many remote units do you have talking to each access point?
l What channels are you using, and how are they dispersed?
l How much coverage overlap is there between access points?
l How high above the floor are the access points mounted?
l What other electronic equipment is operating in the same band?
l What construction materials are used in wall and floors?

Use "CTS-to-self enable" to improve performance in mixed mode environments where 11g and 11b clients are in close proximity and can hear each other. Ad Hoc Transmit Rates Overview The following describes how the wireless preference modes operate using Ad Hoc mode. The adapter can operate in three modes:
l Connect to 802.11g and 802.11b: mixed mode (default setting). The adapter will search for either 11g or 11b access points using data transmit rates of 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps. This connection defaults to 11g access points. The Available Networks list displays all 11b and 11g access points. l Connect to 802.11g only: The adapter will search for a 11g access point only using data transmit rates of 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps. The Available Networks list displays only 11g access points. l Connect to 802.11b only: The adapter will search for the best 11b and 11g access points using data rates of 1, 2, 5.5, or 11 Mbps. The Available Networks list displays any 11b and 11g access point. When different modulation settings are used in ad hoc mode, they influence the computer in the following ways:
l It determines to which ad hoc network we are allowed to connect to. l It determines whom we show in our scan list. A station in an ad hoc network constantly adapts itself to the current situation in the ad hoc network as far as other stations capabilities are concerned. Updating of the supported transmit data rates is done in the following way:
Only the basic rates change. Supported rates of a station never change. At all times the basic rates advertised by stations in an ad hoc network should be the same, and should reflect the set of basic rates supported by every station in this ad hoc network. Since basic rates is the actual information used by a station to decide if it can join the ad hoc network then this is enough to determine if a station can or cannot connect to this ad hoc network. Mixed Mode Mixed mode stations (802.11g and 802.11b) are able to join any ad hoc network they hear. Joining an ad hoc network l Join an 11b ad hoc network only keep the supported rates and update the basic rates to fit the ad hoc network you are joining. Protection (RTS/CTS or CTS-to-self) is on. l Join an 11g ad hoc network only keep the supported rates and up scale the basic rates advertised in the beacons. Note that this is not good because the station ceases being a mixed mode and become an 11g only station. l Join an 11a and 11b ad hoc network only keep the supported rates and update the basic rates to fit the ad hoc network you are joining. Initiating an ad hoc network When initiating a mixed mode ad hoc network the default rates for mixed mode is: 1, 2, 5.5, 11, 6, 12, 18, 24, 36, 48 and 54 Mbps with rates 1, 2 as basic. When other stations join in, the basic rates are down scaled if required. Protection is on when 11b station are joining. 11b only mode Joining an ad hoc network In this mode you can only join an ad hoc network that advertises only basic data rates of 1, 2, 5.5, or 11 Mbps. So, the list of potential ad hoc networks will include 11b and 11b and 11g, but not 11g. Supported rates remain unchanged, and basic rates are adapted to match those advertised by the ad hoc network which you are joining in the beacons. Initiating an ad hoc network When initiating an 11b only ad hoc network, the following rates 1, 2, 5.5 and 11 Mbps, with 1 and 2 as basic. As other stations join in they down scale their basic rates if required. Protection
(RTS/CTS or CTS-to-self) is on. 11g only mode Initiate an ad hoc network as an 11g only (1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps). Support joining and down scaling in the same way as in Mixed mode. When initiating such an ad hoc network the advertised rates are: 1, 2, 5.5, 6, 11, 12, 18, 24, 36, 48 and 54 with 1, 2, 5.5, 6, 11, 12 and 24 Mbps as basic. 11g only stations are able to join any ad hoc network they hear. Joining an ad hoc network The basic rates in this case are taken from the beacons. l Join an 11b ad hoc network only keep the supported rates and down scale the basic rates to fit the ad hoc network you are joining. Protection (RTS/CTS or CTS-to-self) is on. l Join an 11g ad hoc network only keep the supported rates and adopt the basic rates advertised in the beacons. l Join an 11a and 11b ad hoc network only keep the supported rates and update the basic rates to fit the ad hoc network you are joining. Initiating an ad hoc network When initiating an 11g only ad hoc network the advertised rates are: 1, 2, 5.5, 6, 11, 12, 18, 24, 36, 48 and 54 Mbps with 1, 2, 5.5, 6, 11, 12 and 24 Mbps as basic. When other stations join in, the basic rates are down scaled if required. Protection (RTS/CTS or CTS-to-self) is on when 11b station is joining. Creating a New Profile To add a new profile, use the Profile Wizard sequence of dialogs to configure the profile contents. The following example uses all of the Profile Wizard dialogs, although some of the settings may not be required. To create a new profile and connect to a network:

Back to Contents Page Security Overview: Intel(R) PRO/Wireless 2200BG User's Guide Encryption Overview WEP Encryption and Authentication 802.1x Authentication What is a RADIUS Wi-Fi Protected Access (WPA) PEAP Cisco LEAP Encryption Overview Security in the WLAN can be supplemented by enabling data encryption using WEP
(Wireless Encryption Protocol). You can choose a 64 or 128 bit level encryption. Also, the data can then be encrypted with a key. Another parameter called the key index provides the option to create multiple keys for that profile. However, only one key can be used at a time. You can also choose to password protect an Intel(R) PROSet for Wireless profile to ensure privacy. The pass phrase is used to generate a WEP key automatically. You have the option of either using a pass phrase or entering a WEP key manually. Using 64-bit encryption, the pass phrase is 5 characters long and you can choose to enter any arbitrary and easy to remember phrase like Acme1 or enter 10 Hexadecimal numbers for the WEP key corresponding to the network the user wants to connect to. For 128-bit encryption, the pass phrase is 13 characters long or you can enter a 26 hexadecimal numbers for the WEP key to get connected to the appropriate network. WEP Encryption and Authentication Wired Equivalent Privacy (WEP) encryption and shared authentication provides protection for your data on the network. WEP uses an encryption key to encrypt data before transmitting it. Only computers using the same encryption key can access the network or decrypt the encrypted data transmitted by other computers. Authentication provides an additional validation process from the adapter to the access point. Supported a authentication schemes are Open and Shared-Key authentication:
l Shared-Key authentication is supported using 64-bit and 128-bit WEP encryption l Open mode does not use an encryption authentication method to associate to a keys. specific access point. Network Keys When Data Encryption (WEP, CKIP or TKIP) is enabled, a network key is used for encryption. A network key can be provided for you automatically (for example, it might be provided on your wireless network adapter, or enter it yourself and specify the key length
(64-bits or 128-bit), key format (ASCII characters or hexadecimal digits), and key index
(the location where a specific key is stored). The longer the key length, the more secure the key. Every time the length of a key is increased by one bit, the number of possible keys double. Under 802.11, a wireless station can be configured with up to four keys (the key index values are 1, 2, 3, and 4). When an access point or a wireless station transmits an encrypted message using a key that is stored in a specific key index, the transmitted message indicates the key index that was used to encrypt the message body. The receiving access point or wireless station can then retrieve the key that is stored at the key index and use it to decode the encrypted message body. Encryption Static and Dynamic Key Types 802.1x uses two types of encryption keys, static and dynamic. Static encryption keys are changed manually and are more vulnerable. MD5 authentication only uses static encryption keys. Dynamic encryption keys are renewed automatically on a periodic basis. This makes the encryption key(s) more secure. To enable dynamic encryption keys, you must use 802.1x certificate-based authentication methods, such as TLS or TTLS or PEAP. 802.1x Authentication 802.1x features l 802.1x supplicant protocol support l Support for the Extensible Authentication Protocol (EAP) - RFC 2284 l Supported Authentication Methods:
l MD5 - RFC 2284 l EAP TLS Authentication Protocol - RFC 2716 and RFC 2246 l EAP Tunneled TLS (TTLS) l Cisco LEAP l PEAP l Supports Windows XP, 2000 802.1x Authentication Notes l 802.1x authentication methods, include passwords, certificates, and smart cards
(plastic cards that hold data) l 802.1x authentication option can only be used with Infrastructure operation mode l Network Authentication modes are: EAP-TLS, EAP-TTLS, MD5 Challenge, LEAP
(for Cisco-Client eXtentions mode only), and PEAP (for WPA modes only) Overview 802.1x authentication is independent of the 802.11 authentication process. The 802.1x standard provides a framework for various authentication and key-management protocols. There are different 802.1x authentication types, each providing a different approach to authentication but all employing the same 802.1x protocol and framework for communication between a client and an access point. In most protocols, upon the completion of the 802.1x authentication process, the supplicant receives a key that it uses for data encryption. With 802.1x authentication, an authentication method is used between the client and a Remote Authentication Dial-In User Service (RADIUS) server connected to the access point. The authentication process uses credentials, such as a user's password that are not transmitted over the wireless network. Most 802.1x types support dynamic per-user, per-session keys to strengthen the static key security. 802.1x benefits from the use of an existing authentication protocol known as the Extensible Authentication Protocol (EAP). 802.1x authentication for wireless LANs has three main components: The authenticator
(the access point), the supplicant (the client software), and the authentication server (a Remote Authentication Dial-In User Service server (RADIUS). 802.1x authentication security initiates an authorization request from the WLAN client to the access point, which authenticates the client to an Extensible Authentication Protocol (EAP) compliant RADIUS server. This RADIUS server may authenticate either the user (via passwords or certificates) or the system (by MAC address). In theory, the wireless client is not allowed to join the networks until the transaction is complete. There are several authentication algorithms used for 802.1x; MD5-Challenge, EAP-TLS, EAP-TTLS, Protected EAP
(PEAP), and EAP Cisco Wireless Light Extensible Authentication Protocol (LEAP). These are all methods for the WLAN client to identify itself to the RADIUS server. With RADIUS authentication, users identities are checked against databases. RADIUS constitutes a set of standards addressing Authentication, Authorization and Accounting (AAA). Radius includes a proxy process to validate clients in a multi-server environment. The IEEE 802.1x standard is for controlling and authenticating access to port-based 802.11 wireless and wired Ethernet networks. Port-based network access control is similar to a switched local area network (LAN) infrastructure that authenticates devices that are attached to a LAN port and prevent access to that port if the authentication process fails. How 802.1x authentication works A simplified description of the 802.1x authentication is:
1. A client sends a "request to access" message to an access point. The access point requests the identity of the client. 2. The client replies with its identity packet which is passed along to the 3. The authentication server sends an "accept" packet to the access point. 4. The access point places the client port in the authorized state and data traffic is authentication server. allowed to proceed. Refer to Setting up the Client for WEP and MD5 authentication for details about setting up an 802.1x profile using the Intel(R) PROSet for Wireless utility. What is a RADIUS?
RADIUS is the Remote Access Dial-In User Service, an Authorization, Authentication, and Accounting (AAA) client-server protocol for when a AAA dial-up client logs in or out of a Network Access Server. Typically, a RADIUS server is used by Internet Service Providers (ISP) to performs AAA tasks. AAA phases are described as follows:
l Authentication phase: Verifies a user name and password against a local database. After the credentials are verified, the authorization process begins. l Authorization phase: Determines whether a request will be allowed access to a resource. An IP address is assigned for the Dial-Up client. l Accounting phase: Collects information on resource usage for the purpose of trend analysis, auditing, session time billing, or cost allocation. Wi-Fi Protected Access* (WPA) Wi-Fi Protected Access (WPA) is a security enhancement that strongly increases the level of data protection and access control to a WLAN. WPA mode enforces 802.1x authentication and key-exchange and only works with dynamic encryption keys. To strengthen data encryption, WPA utilizes its Temporal Key Integrity Protocol (TKIP). TKIP provides important data encryption enhancements that include a per-packet key mixing function, a Message Integrity Check (MIC) named Michael an extended initialization vector (IV) with sequencing rules, and a also re-keying mechanism. Using these improvement enhancements, TKIP protects against WEP's known weaknesses. PEAP PEAP is a new Extensible Authentication Protocol (EAP) IEEE 802.1x authentication type designed to take advantage of server-side EAP-Transport Layer Security (EAP-TLS) and to support various authentication methods, including user's passwords and one-time passwords, and Generic Token Cards. Cisco LEAP Cisco LEAP (EAP Cisco Wireless) is a server and client 802.1x authentication via a user-
supplied logon password. When a wireless access point communicates with a Cisco LEAP-enabled RADIUS (Cisco Secure Access Control Server (ACS) server), Cisco LEAP provides access control through mutual authentication between client wireless adapters and the wireless network and provides dynamic, individual user encryption keys to help protect the privacy of transmitted data. Cisco Rogue AP security feature The Cisco Rogue AP feature provides security protection from an introduction of a rogue access point that could mimic a legitimate access point on a network in order to extract information about user credentials and authentication protocols which could compromise security. This feature only works with Cisco's LEAP authentication. Standard 802.11 technology does not protect a network from the introduction of a rogue access point. CKIP Cisco Key Integrity Protocol (CKIP) is Cisco proprietary security protocol for encryption in 802.11 media. CKIP uses the following features to improve 802.11 security in infrastructure mode:
l Key Permutation l Message Integrity Check l Message Sequence Number Mixed-Cell Some access points, for example Cisco 350 or Cisco 1200, support environments in which not all client stations support WEP encryption, this is called Mixed-Cell Mode. When these wireless network operate in optional encryption mode, client stations that join in WEP mode, send all messages encrypted, and stations, that join in using standard mode, send all messages unencrypted. These APs broadcast that the network is not using encryption, but allow clients to join using WEP mode. When Mixed-Cell is enabled in a profile, it allows you to connect to access points that are configured for optional encryption. NOTE: Make sure to enable the Advanced Settings Mixed-Cell (Requires Cisco CCX option) when using Enable Cisco-Client eXtentions in a profile. A Cisco CCX enabled profile uses CKIP data encryption and 802.1x LEAP authentication. Back to Contents Page Please read all restrictions and disclaimers.

WEP uses an encryption key to encrypt data before transmitting it. Only computers using the same encryption key can access the network or decrypt the encrypted data transmitted by other computers. Authentication provides an additional validation process from the adapter to the access point. The WEP encryption algorithm is vulnerable to passive and active network attacks. TKIP and CKIP algorithms include enhancements to the WEP protocol that mitigate existing network attacks and address its shortcomings. Open and Shared Key authentication 802.11 support two types of network authentication methods; Open System and Shared that use 64-bit and 128-bit WEP encryption. Open does not require an encryption authentication method to associate to a specific access point. Supported authentication schemes are Open and Shared authentication:
l Using Open authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless station sends an authentication management frame that contains the identity of the sending station. The receiving station or AP will grant any request for authentication. Open authentication allows any device network access. If no encryption is enabled on the network, any device that knows the SSID of the access point can gain access to the network. l Using Shared authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel. Shared key authentication requires that the client configure a static WEP key. The client access will be granted only if it passed a challenge based authentication. Network Keys When Data Encryption (WEP, CKIP or TKIP) is enabled, a network key is used for encryption. A network key can be provided for you automatically (for example, it might be provided on your wireless network adapter, or you can enter it yourself and specify the key the key length (64-bits or 128-bit), key format (ASCII characters or hexadecimal digits), and key index (the location where a specific key is stored). The longer the key length, the more secure the key. Every time the length of a key is increased by one bit, the number of possible keys double. Under 802.11, a wireless station can be configured with up to four keys (the key index values are 1, 2, 3, and 4). When an access point or a wireless station transmits an encrypted message using a key that is stored in a specific key index, the transmitted message indicates the key index that was used to encrypt the message body. The receiving access point or wireless station can then retrieve the key that is stored at the key index and use it to decode the encrypted message body. Encryption Static and Dynamic Key Types 802.1x uses two types of encryption keys, static and dynamic. Static encryption keys are changed manually and are more vulnerable. MD5 authentication only uses static encryption keys. Dynamic encryption keys are renewed automatically on a periodic basis. This makes the encryption key(s) more secure. To enable dynamic encryption keys, you must use 802.1x authentication methods, such as TLS, TTLS, PEAP or LEAP. Encryption Overview Security in the WLAN can be supplemented by enabling data encryption using WEP
(Wireless Encryption Protocol). You can choose a 64 or 128 bit level encryption. Also, the data can then be encrypted with a key. Another parameter called the key index is provides the option to create multiple keys for that profile. However, only one key can be used at a time. You can also choose to password protect the profile to ensure privacy. The pass phrase is used to generate a WEP key automatically. You have the option of either using a pass phrase or entering a WEP key manually. Using 64-bit encryption, the pass phrase is 5 characters long and you can choose to enter any arbitrary and easy to remember phrase like, Acme1, or enter 10 Hexadecimal characters for the WEP key that matches the network that the connects to. For 128-bit encryption, the pass phrase is 13 characters long or you can enter a 26 hexadecimal characters for the WEP key to get connected to the appropriate network. Note: You must use the same encryption type, key index number, and WEP key as other devices on your wireless network. How to Enable WEP Encryption The following example describes how to edit an existing profile and apply WEP encryption. Note: Before you begin, contact your system administrator for the network WEP pass phrase or Hex Key. To enable WEP encryption:
1. From the General page, click the Networks tab. 2. Select the profile from the Profile List and click the Edit button. 3. Click the Security tab. 4. Select any Network Authentication mode (Open is recommended). 5. Select WEP for Data Encryption. 6. Select 64-bit or 128-bit for the Encryption Level. 7. Select a key index number 1, 2, 3, or 4. 8. Select either of the following:
l Use pass phrase: Click Use Pass Phrase to enable. Enter a text phrase, up to five (using 64-bit) or 13 (using 128-bit) alphanumeric characters (0-9, a-z or A-Z), in the pass phrase field. l Use hex Key: Click Use hex Key to enable. Enter up to ten (using 64-
bit) alphanumeric characters, 0-9, A-F, or twenty-six (using 128-bit) alphanumeric characters, 0-9, A-F in the hex key field. 9. Click OK to save the profiles settings. System Administrator Tasks NOTE: The following information is intended for system administrators. How to Obtain a Client Certificate If you do not have any certificates for EAP-TLS, or EAP-TTLS you must get a client certificate to allow authentication. Typically you need to consult with your system network administrator for instructions on how to obtain a certificate on your network. Certificates can be managed from "Internet Settings", accessed from either Internet Explorer or the Windows Control Panel applet. Use the "Content" page of "Internet Settings". Windows XP and 2000: When obtaining a client certificate, do not enable strong private key protection. If you enable strong private key protection for a certificate, you will need to enter an access password for the certificate each time this certificate is used. You must disable strong private key protection for the certificate if you are configuring the service for TLS/TTLS authentication. Otherwise the 802.1x service will fail authentication because there is no logged in user to whom it can display the prompt dialog. Notes about Smart Cards After installing a Smart Card, the certificate is automatically installed on your computer and can be select from the person certificate store and root certificate store. Setting up the Client for TLS authentication Step 1: Getting a certificate To allow TLS authentication, you need a valid client (user) certificate in the local repository for the logged-in users account. You also need a trusted CA certificate in the root store. The following information provides two methods for getting a certificate;
l from a corporate certification authority implemented on a Windows 2000 Server l using Internet Explorers certificate import wizard to import a certificate from a file Getting a certificate from a Windows 2000 CA:
1. Start Internet Explorer and browse to the Certificate Authority HTTP Service (use a URL such as http://yourdomainserver.yourdomain/certsrv with certsrv being the command that brings you to the certificate authority. You can also use the IP address of the server machine, such as"192.0.2.12/certsrv."
2. Logon to the CA with the name and password of the user account you created
(above) on the authentication server. The name and password do not have to be the same as the Windows logon name and password of your current user. 3. On the Welcome page of the CA select Request a certificate task and submit the form. 4. On the Choose Request Type page, select Advanced request, then click Next. 5. On the Advanced Certificate Requests page, select Submit a certificate request to this CA using a form, then click Submit. 6. On the Advanced Certificate Request page choose the User certificate template. Select "Mark keys as exportable", and click Next. Use the provided defaults shown. 7. On the Certificate Issued page select Install this certificate. Note: If this is the first certificate you have obtained, the CA will first ask you if it should install a trusted CA certificate in the root store. The dialog will not say this is a trusted CA certificate, but the name on the certificate shown will be that of the host of the CA. Click yes, you need this certificate for both TLS and TTLS. 8. If your certificate was successfully installed, you will see the message, "Your new certificate has been successfully installed."
9. To verify the installation, click Internet Explorer > Tools > Internet Options >
Content > Certificates. The new certificate should be installed in "Personal"
folder. Importing a certificate from a file 1. Open Internet Properties (right-click on the Internet Explorer icon on the desktop 2. Click the Certificates button on the Content page. This will open the list of installed and select Properties. certificates. 3. Click the Import button under the list of certificates. This will start the Certificate Import Wizard. (Note: Steps 1 through 3 may also be accomplished by double-
clicking the icon for the certificate. 4. Select the file and proceed to the Password page. 5. On the Password page specify your access password for the file. Clear the Enable strong private key protection option. 6. On the Certificate store page select "Automatically select certificate store based on the type of certificate" (the certificate must be in the User accounts Personal store to be accessible in the Configure dialog of the Client; this will happen if automatic is selected). 7. Proceed to "Completing the Certificate Import" and click the Finish button. The following example describes how to use WPA with TKIP encryption using TTLS or PEAP authentication. Setting up the Client for TLS authentication Step 2: Specifying the certificate used by Intel(R) PROSet for Wireless 1.

Under the "Client certificate" option click the Select button to open a list of installed l Note about Certificates: The specified identity should match the field "Issued to" in the certificate and should be registered on the authentication server
(i.e., RADIUS server) that is used by the authenticator. Your certificate must be "valid" with respect to the authentication server. This requirement depends on the authentication server and generally means that the authentication server must know the issuer of your certificate as a Certificate Authority. You should be logged in using the same username you used when the certificate was installed. 16. Select the certificate from the list and click OK.

(i.e., RADIUS server) that is used by the authenticator. Your certificate must be "valid" with respect to the authentication server. This requirement depends on the authentication server and generally means that the authentication server must know the issuer of your certificate as a Certificate Authority. You should be logged in using the same username you used when the certificate was installed. 15. Select the certificate from the list and click OK. The client certificate information displays under "Client Certificate". 16. Click Close. 17. Click the Finish button to save the security settings for the profile. Setting up the Client for WPA using TKIP encryption and TTLS or PEAP authentication Using TTLS authentication: These settings define the protocol and the credentials used to authenticate a user. In TTLS, the client uses EAP-TLS to validate the server and create a TLS-encrypted channel between the client and server. The client can use another authentication protocol, typically password-based protocols, such as MD5 Challenge over this encrypted channel to enable server validation. The challenge and response packets are sent over a non-exposed TLS encrypted channel. Using PEAP authentication: PEAP settings are required for the authentication of the client to the authentication server. In PEAP, the client uses EAP-TLS to validate the server and create a TLS-encrypted channel between client and server. The client can use another EAP mechanism, such as Microsoft Challenge Authentication Protocol
(MSCHAP) Version 2, over this encrypted channel to enable server validation. The challenge and response packets are sent over a non-exposed TLS encrypted channel. The following example describes how to use WPA with TKIP encryption using TTLS or PEAP authentication. 1. Obtain and install a client certificate, refer to Setting up the Client for TLS authentication or consult your system administrator. 2. From the General page, click the Networks tab. 3.

Click OK to save the settings and connect to the network. CCX Access Point and Client Configurations The access point provides settings to select different authentication types depending on the WLAN environment. The client sends an Authentication algorithm field during the 802.11 authentication handshake that takes place between the client and the AP during connection establishment. The Authentication algorithm values recognized by a CCX enabled AP is different for the different authentication types. For instance "Network-EAP"
which denotes LEAP has a value of 0x80 while "Open" which is the 802.11 specified Open authentication and "Required EAP" which requires an EAP handshake exchange have values of 0x0. Network-EAP only AP: For CCX enabled networks using LEAP authentication only the authentication type is set with "Network-EAP" checkbox selected, and "Open" and "Required EAP" boxes unchecked. The AP is then configured to allow LEAP clients ONLY to authenticate and connect. In this case, the AP expects the 802.11 authentication algorithm to be set to 0x80 (LEAP), and rejects clients that attempt authentication with an Authentication algorithm value 0x0. Client: In this case the client needs to send out an authentication algorithm value of 0x80 else the 802.11 authentication handshake would fail. During boot, when the Wireless LAN driver is already loaded, but the Intel(R) PROSet for Wireless supplicant is still unloaded, the client sends 802.11 authentication with an Authentication algorithm value of 0x0. Once the Intel(R) PROSet for Wireless supplicant loads, and engages the LEAP profile, it sends 802.11 authentication with an Authentication algorithm value of 0x80. However, the supplicant sends out 0x80 only if the Rogue AP box is checked. Network-EAP, Open and Required EAP AP: If Network-EAP, Open and Required EAP boxes are checked then it would accept both types of 802.11 authentication algorithm values 0x0 and 0x80. However, once the client is associated and authenticated the AP expects an EAP handshake to take place. For any reason if the EAP handshake does not take place quickly, the AP would not respond to the client for about 60 seconds. Client: Here the client could send out an authentication algorithm value of 0x80 or 0x0. Both values are acceptable and the 802.11 authentication handshake would succeed. During boot, when the Wireless LAN driver is already loaded and the client sends 802.11 authentication with an Authentication algorithm value of 0x0. This is sufficient to get authenticated but the corresponding EAP or LEAP credentials need to be communicated to the AP to establish a connection. Open and Required EAP only AP: In the case where the AP is configured with Network-EAP unchecked, but Open and Required EAP checked, the AP will reject any client attempting to 802.11 authenticate using an authentication algorithm value of 0x80. The AP would accept any client using an authentication algorithm value of 0x0, and expects EAP handshake to commence soon after. In this case, the client uses MD5, TLS, LEAP or any other appropriate EAP method suitable for the specific network configuration. Client: The client in this case is required to send out an authentication algorithm value of 0x0. As mentioned before the sequence involves a repeat of the initial 802.11 authentication handshake. First, the Wireless LAN driver initiates authentication with a value of 0x0 and later the supplicant would repeat the process. However, the authentication algorithm value used by the supplicant depends status of the Rogue AP checkbox. When the Rogue AP box is unchecked, the client sends an 802.11 authentication with Authentication algorithm value of 0x0 even after the supplicant loads and engages the LEAP profile. Some non-Intel clients, for example, when set to LEAP, cannot authenticate in this case. However, the Intel Wireless LAN client can authenticate, if the Rogue AP is unchecked. Rogue AP Checkbox configuration When the checkbox is checked it ensures that the client implements the Rogue AP feature as required by CCX. The client makes note of APs that it failed to authenticate with and sends this information to the AP that allows it to authenticate and connect. Also, the supplicant sets the Authentication algorithm type to 0x80 when the Rogue AP box is checked. There may be some network configurations implementing and Open and Required EAP only as described above. For this setup to work, the client must use an Authentication Algorithm value of 0x0, as opposed to the need to use 0x80 for Network-
EAP only described above. Therefore, the Rogue AP checkbox also enables the client to support Network-EAP only and Open and Required EAP only. Cisco CCX Feature Support The Cisco mandatory Client Compliance Specifications Version1.0:

Back to Contents Glossary of Terms: Intel(R) PRO/Wireless 2200BG User's Guide Numerical A B D E F I K M O P R S T U W Numerical 802.11a: The 802.11a standard specifies a maximum data transfer rate of 54Mbps and an operating frequency of 5GHz. The 802.11a standard uses the Orthogonal Frequency Division Multiplexing (OFDM) transmission method. Additionally, the 802.11a standard supports 802.11 features such as WEP encryption for security. 802.11b:The 802.11b standard specifies a maximum data transfer rate of 11Mbps, an operating frequency of 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks. 802.11g: The 802.11g standard specifies a maximum data transfer rate of 54Mbps, an operating frequency of 2.4GHz, and WEP encryption for security. 802.11g networks are also referred to as Wi-Fi networks. 802.11x: A series of IEEE specifications for LANs: currently 802.11b, 802.11a, and 802.11g. Using any one of these extensions to the 802.11 standard permits wireless communication between a client and an access point or between two clients. 802.1x is based on the Extensible Authentication Protocol (EAP), the 802.1x standard is one of the IEEE standards for network authentication and key management. It establishes a framework that supports multiple authentication methods. This standard can be incorporated into any type of network to enhance its security. A Access Point: A device that serves as a communications hub for wireless clients and provides a connection to a wired LAN. Advanced Encryption Standard (AES): A federal information-processing standard, supporting 128-, 192-, and 256-bit keys. B Basic Service Set Identifier (BSSID): A unique identifier for each wireless client on a wireless network. The BSSID is the Ethernet MAC address of each adapter on the network. Bit Rate: The total number of bits (ones and zeros) per second that a network connection can support. Note that this bit rate will vary, under software control, with different signal path conditions. Bluetooth: An incompatible, very short-range lower speed communications system
(PAN), developed first in Europe as a "cable replacement" for printers and similar peripheral connections. Its usage has expanded to include cordless earphones and similar devices. It uses the 2.4 GHz ISM band, and "co-exists" with 802.11b. Here the term, "co-exist" means that not all researchers agree on the amount of mutual interference generated when both systems operate in the same location. Broadcast SSID: Used to allow an access point to respond to clients on a wireless network by sending probes. D Data Rate (Information Rate): Not all bits carry user information. Each group (packet) of bits contains headers, trailers, echo control, destination information, and other data required by the transmission protocol. It is important to understand the difference between bit rate and data rate, since the overhead information may consume more than 40% of the total transmission. This difference is common to many such data systems, including Ethernet. Direct-Sequence Spread Spectrum (DSSS) and Frequency-Hop Spread Spectrum
(FHSS): Two incompatible technologies used in radio transmission. Dynamic IP Address: An IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server. Network devices that serve multiple users, such as servers and printers, are usually assigned static IP addresses. E Extensible Authentication Protocol (EAP): An IETF standard that establishes an authentication protocol for network access. Many authentication methods, including passwords, certificates, and smart cards, work within this framework. EAP-TLS: A type of authentication method using the Extensible Authentication Protocol
(EAP) and a security protocol called the Transport Layer Security (TLS). EAP-TLS uses certificates which use passwords. EAP-TLS authentication supports dynamic WEP key management. EAP-TTLS: A type of authentication method using the Extensible Authentication Protocol
(EAP) and Tunneled Transport Layer Security (TTLS). EAP-TTLS uses a combination of certificates and another method, such as passwords. It is more secure than MD5 authentication, which uses passwords, and less secure than EAP-TLS authentication, which exclusively uses certificates. EAP-TTLS authentication supports dynamic WEP key management. Encryption: Scrambling data so that only the authorized recipient can read it. Usually a key is needed to decrypt the data. Extended Service Set IDentifier (ESSID): A type of unique identifier applied to both the AP and the wireless PC Card that is attached to each packet. This allows the AP to recognize each wireless client and its traffic. F Firewall:A firewall is a set of related programs, located at a network gateway server, that protects the resources of a network from users from other networks. Frequencies: Strike a piano key and you generate a tone. Pick up the tone with a microphone and your tone turns in to a "vibrating" or "cycling" electronic signal. The rate of vibration depends on the key struck. In electronics we refer to this rate of vibration as the number of "cycles per second." The formal term for this value is Hertz. As we move up in rate, such as in the Broadcast Band, we can use Kilohertz (KHz) to represent 1,000 Hz, or Megahertz (MHz) to represent 1,000,000 Hz. Continuing much further upward, we finally reach 1,000,000,000 Hz, which we can fortunately shorten to a Gigahertz (GHz). These frequencies are the home of both 802.11a (5 GHz) and 802.11b (2.4 GHz). I Independent Basic Service Set Identifier (IBSSID): Used to identify a wireless network configured to allow each wireless client to communicate directly with each other without an access point. Independent Network: A network that provides (usually temporarily) peer-to-peer connectivity without relying on a complete network infrastructure. Infrastructure Network: A wireless network centered around an access point. In this environment, the access point not only provides communication with the wired network but also mediates wireless network traffic in the immediate neighborhood. Institute of Electrical and Electronics Engineers (IEEE): An organization involved in setting computing and communications standards. ISM Bands: A series of frequency bands, set aside by the FCC for Industrial, Scientific and Medical applications. Users of these bands operate equipment on a shared basis, meaning that they must expect, and accept interference from other legal users. Products manufactured for ISM Band use must be approved by the FCC, but the user does not have to be licensed. In addition to WLAN, ISM bands support cordless phones, microwave ovens, baby monitors, toys, ham radio transceivers, and other wireless services. K Kerberos: An authentication system enabling protected communication over an open network using a unique key called a ticket. M Media Access Control (MAC) Address: A hardwired address applied at the factory. It uniquely identifies network hardware, such as a wireless PC Card, on a LAN or WAN. Microcell: A bounded physical space in which a number of wireless devices can communicate. Because it is possible to have overlapping cells as well as isolated cells, the boundaries of the cell are established by some rule or convention. Microwave: Technically, the term describes any frequency above 1.0 GHz. Unfortunately the advertising industry has contorted this meaning considerably. In our discussion we will stick to the technical definition. Multipath: The signal variation caused when radio signals take multiple paths from transmitter to receiver. O Orthogonal Frequency Division Multiplexing (OFDM): A modulation technique for transmitting large amounts of digital data over radio waves. 802.11a uses OFDM, as will 802.11g. P Peer-to-Peer Mode: A wireless network structure that allows wireless clients to communicate with each other without using an access point. Personal Area Network (PAN): A personal area network, or PAN, is a networking scheme that enables computing devices such as PCs, laptop computers, handheld personal computers, printers and personal digital assistants (PDAs) to communicate with each other over short distances either with or without wires. Preamble: A preliminary signal transmitted over a WLAN to control signal detection and clock synchronization. R Radio Frequency (RF) Terms (GHz, MHz, Hz): The international unit for measuring frequency is Hertz (Hz), which is equivalent to the older unit of cycles per second. One Mega-Hertz (MHz) is one million Hertz. One Giga-Hertz (GHz) is one billion Hertz. For reference: the standard US electrical power frequency is 60 Hz, the AM broadcast radio frequency band is 0.55 -1.6 MHz, the FM broadcast radio frequency band is 88-108 MHz, and microwave ovens typically operate at 2.45 GHz. Range: The distance over which a given system can communicate. RC4: An encryption algorithm designed at RSA Laboratories; specifically, a stream cipher of pseudo-random bytes that is used in WEP encryption. Remote Authentication Dial-In User Service (RADIUS): An authentication and accounting system that verifies users' credentials and grants access to requested resources. Roaming: Movement of a wireless node between two microcells. Roaming usually occurs in infrastructure networks built around multiple access points. S Service Set Identifier (SSID): Used to identify clients on a wireless network. Shared key: An encryption key known only to the receiver and sender of data. Site Survey: A process where you set up one transceiver in a fixed location, and then use another unit to plot the field strength of the first units transmitted signal. By moving the transmitter around, and repeating the plots, you can develop a plan as to the best locations for access points. You will also identify dead zones and other areas in need of special attention. This can be a long, slow process, but it beats ripping up an unsatisfactory installation and starting over. These tests require special software commands. Refer to your manual for specific instructions. If you have a very large, or unusually complex installation situation, you might want to consider calling in professionals to do your survey. We are not permitted to suggest installer names, but you can check your yellow pages or similar sources for likely candidates. Static IP Address: A permanent IP address that is assigned to a node in a TCP/IP network. T Transmission Control Protocol (TCP): A method (protocol) used with the IP (Internet Protocol) to send data in the form of message units between network devices over a LAN or WAN. The IP carries the delivery of the data (routing), and TCP keeps track of the individual units of data (called packets) that a message is divided into for delivery over the network. Transmission Control Protocol/Internet Protocol (TCP/IP): The basic communication language or set of protocols for communications over a network (developed specifically for the Internet). TCP/IP defines a suite or group of protocols and not only TCP and IP. Transceiver: A commonly used term that describes a combination transmitter and receiver. Both 802.11a and 802.11b devices would be properly described as data transceivers. U UNII Bands: Unlicensed National Information Infrastructure. In contrast to the ISM bands, these are a group of frequency bands set aside by the FCC for WLAN type communications only. Users must accept interference from other legal WLAN users, but the other sources of interference problems are, or legally should be, missing. W WEP64 and WEP128: Wired Equivalent Privacy, 64 bit and 128 bit (64 bit is sometimes referred to as 40 bit). This is a low-level encryption technique designed to give the user about the same amount of privacy that he would expect from a LAN. It is extremely important to understand that WEP is not some CIA-proof supercode! It performs as intended, giving the user a simple level of data security and protection from casual electronic eavesdropping. Use of the 128 bit option at all possible times is recommended. Remember that 802.11 devices transmit (broadcast) in all directions, and that it is possible, with very complex software, to copy and decode WEP transmissions. The task is not trivial, but it is possible. If your data is extremely sensitive, you should consider some form of secondary protection, such as strong passwords and an additional level of encryption. Suitable software packages are available from reputable suppliers. Although not intended by the original architects, WEP also helps prevents unauthorized access to your system by an outsider. Hackers have been known to access systems from outside a building, and to then to access the Web for a leisurely session, all at the system owners expense.
