Wireless LAN Basics Wireless LAN network defined by IEEE 802.11b/g/n standard committee can be configured in the following modes:

Ad Hoc (Point-to-point) wireless LAN. Infrastructure wireless LAN. Infrastructure Wireless Network Ad Hoc Wireless Network Ad Hoc network is a group of PCs installed with wireless LAN cards, this group of PCs is called a BSS (Basic Service Set). PCs in this group can use their wireless LAN cards to communicate with each other, but cannot connect to the Internet. The main difference between Infrastructure wireless networks and Ad Hoc wireless networks is that the PCs in an Infrastructure wireless network can access the resource in the Internet through an Access Point. Depending on your application requirements, you can easily set up your PCs network to be an Ad Hoc or Infrastructure wireless network. Generally speaking, if your network includes an Access Point, we recommend setting your network as an Infrastructure network to allow connectivity to the Interne Copyright LM Technologies Ltd www.lm-technologies.com Page 13 of 29 LM821 User Manual 5. IP Address To use this WiFi module with a computing device, the host device must be equipped with a USB interface. All drivers and supporting software for the module must be installed and configured first. Ask your system administrator for the following information, which might be needed during the driver installation:

Wireless Client Name Wireless SSID The hosts unique client and workgroup name For your network account you will need the following:

Username Password IP address Gateway address Subnet mask (if youre not using a DHCP client) Any computer on a network is identified by a unique IP address. There are two methods to assign an IP address to a computer on a TCP/IP network:

Static IP addressing Dynamic IP addressing (DHCP Client) In networks with static IP addressing, the network administrator manually assigns an IP address to each computer. Once a static IP address is assigned, a computer uses the same IP address every time it reboots and logs onto the network. You may manually change the IP address in the Network Properties dialog box. Networks using static IP addresses is easy to set up and do not require additional network management software. In networks with dynamic IP addressing, a DHCP server in the network dynamically assigns IP addresses to all clients every time they log onto the network. Networks using dynamic IP addresses require setting up and running a DHCP Server. Copyright LM Technologies Ltd www.lm-technologies.com Page 14 of 29 LM821 User Manual 6.

Glossary LM821 User Manual IEEE 802.11 Standard The IEEE 802.11 Wireless LAN standards subcommittee, which is formulates a standard for the industry. Access Point An internetworking device that seamlessly connects wired and wireless networks together. Ad Hoc An Ad Hoc wireless LAN is a group of computers, each with a WLAN module, connected as an independent wireless LAN. Ad Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. BSSID A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSSID. DHCP Dynamic Host Configuration Protocol - a method in which IP addresses are assigned by a server dynamically to clients on the network. DHCP is used for Dynamic IP Addressing and requires a dedicated DHCP server on the network. Direct Sequence Spread Spectrum This is the method the wireless cards use to transmit data over the frequency spectrum. The other method is frequency hopping. Direct sequence spreads the data over one frequency range (channel) while frequency hopping jumps from one narrow frequency band to another many times per second. ESSID An Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS could roam freely between BSSs while served as a continuous connection to the network wireless stations and Access Points within an ESS must be configured with the same ESSID and the same radio channel. Ethernet Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users must be wired to the network at all times to gain access. Gateway A gateway is a hardware and software device that connects two dissimilar systems, such as a LAN and a mainframe. In Internet terminology, a gateway is another name for a router. Generally a gateway is used as a funnel for all traffic to the Internet. Copyright LM Technologies Ltd www.lm-technologies.com Page 25 of 29 LM821 User Manual IEEE Institute of Electrical and Electronics Engineers Infrastructure An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. ISM Band The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the so-called ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe. Local Area Network (LAN) A LAN is a group of computers, each equipped with the appropriate network module card connected by cable/air, that share applications, data and peripherals. All connections are made via cable or wireless media, but a LAN does not use telephone services. It typically spans a single building or campus. Network A network is a system of computers that is connected. Data, files, and messages can be transmitted over this network. Networks may be local or wide area networks. Protocol A protocol is a standardized set of rules that specify how a conversation is to take place, including the format, timing, sequencing and/ or error checking. SSID A Network ID is unique to a network. Only clients and Access Points that share the same SSID are able to communicate with each other. This string is case-sensitive. Static IP Addressing A method of assigning IP addresses to clients on the network. In networks with a Static IP address, the network administrator manually assigns an IP address to each computer. Once a Static IP address is assigned, a computer uses the same IP address every time it reboots and logs on to the network, unless it is manually changed. Copyright LM Technologies Ltd www.lm-technologies.com Page 26 of 29 LM821 User Manual Temporal Key Integrity Protocol (TKIP) The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryption standard for wireless LANs. TKIP is the next generation of WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a message integrity check and a re-keying mechanism, thus fixing the flaws of WEP. Transmission Control Protocol / Internet Protocol (TCP/IP) TCP/IP is the protocol suite developed by the Advanced Research Projects Agency (ARPA). It is widely used in corporate Internet works, because of its superior design for WANs. TCP governs how packet is sequenced for transmission the network. The term TCP/IP is often used generically to refer to the entire suite of related protocols. Transmit / Receive The wireless throughput in Bytes per second averaged over two seconds. Wi-Fi Alliance The Wi-Fi Alliance is a nonprofit international association formed in 1999 to certify interoperability of wireless Local Area Network products based on IEEE 802.11 specification. The goal of the Wi-Fi Alliances members is to enhance the user experience through product interoperability. The organization is formerly known as WECA. Wi-Fi Protected Access (WPA) The Wi-Fi Alliance put together WPA as a data encryption method for 802.11 wireless LANs. WPA is an industry-supported, pre-standard version of 802.11i utilizing the Temporal Key Integrity Protocol (TKIP), which fixes the problems of WEP, including using dynamic keys. Wide Area Network (WAN) A WAN consists of multiple LANs that are tied together via telephone services and /

or fiber optic cabling. WANs may span a city, a state, a country, or even the world. Wired Equivalent Privacy (WEP) Now widely recognized as flawed, WEP was a data encryption method used to protect the transmission between 802.11 wireless clients and APs. However, it used the same key among all communicating devices. WEPs problems are well-known, including an insufficient key length and no automated method for distributing the keys. WEP can be easily cracked in a couple of hours with off-the-shelf tools. Advanced Encryption Standard (AES) Security issues are a major concern for wireless LANs, AES is the U.S. governments next-generation cryptography algorithm, which will replace DES and 3DE Copyright LM Technologies Ltd www.lm-technologies.com Page 27 of 29 LM821 User Manual Wireless LAN (WLAN) A wireless LAN does not use cable to transmit signals, but rather uses radio or infrared to transmit packets through the air. Radio Frequency

(RF) and infrared are the commonly used types of wireless transmission. Most wireless LANs use spread spectrum technology. It offers limited bandwidth, usually under 11Mbps, and users share the bandwidth with other devices in the spectrum; however, users can operate a spread spectrum device without licensing from the Federal Communications Commission (FCC). Fragment Threshold The proposed protocol uses the frame fragmentation mechanism defined in IEEE 802.11 to achieve parallel transmissions. A large data frame is fragmented into several fragments each of size equal to fragment threshold. By tuning the fragment threshold value, we can get varying fragment sizes. The determination of an efficient fragment threshold is an important issue in this scheme. If the fragment threshold is small, the overlap part of the master and parallel transmissions is large. This means the spatial reuse ratio of parallel transmissions is high. In contrast, with a large fragment threshold, the overlap is small and the spatial reuse ratio is low. However high fragment threshold leads to low fragment overhead. Hence there is a trade-off between spatial re-use and fragment overhead. Fragment threshold is the maximum packet size used for fragmentation. Packets larger than the size programmed in this field will be fragmented If you find that your corrupted packets or asymmetric packet reception (all send packets, for example). You may want to try lowering your fragmentation threshold. This will cause packets to be broken into smaller fragments. These small fragments, if corrupted, can be resent faster than a larger fragment. Fragmentation increases overhead, so you'll want to keep this value as close to the maximum value as possible. RTS (Request To Send) Threshold The RTS threshold is the packet size at which packet transmission is governed by the RTS/CTS transaction. The IEEE 802.11-1997 standard allows for short packets to be transmitted without RTS/CTS transactions. Each station can have a different RTS threshold. RTS/CTS is used when the data packet size exceeds the defined RTS threshold. With the CSMA/CA transmission mechanism, the transmitting station sends out an RTS packet to the receiving station, and waits for the receiving station to send back a CTS (Clear to Send) packet before sending the actual packet data. This setting is useful for networks with many clients. With many clients, and a high network load, there will be many more collisions. By lowering the RTS threshold, there may fewer collisions, and performance should improve. Basically, with a faster RTS threshold, the Copyright LM Technologies Ltd www.lm-technologies.com Page 28 of 29 system can recover from problems faster. RTS packets consume valuable bandwidth, however, so setting this value too low will limit performance. LM821 User Manual Beacon Interval In addition to data frames that carry information from higher layers, 802.11 includes management and control frames that support data transfer. The beacon frame, which is a type of management frame, provides the "heartbeat" of a wireless LAN, enabling stations to establish and maintain communications in an orderly fashion. Beacon Interval represents the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). Preamble Type There are two preamble types defined in IEEE 802.11 specification. A long preamble basically gives the decoder more time to process the preamble. All 802.11 devices support a long preamble. The short preamble is designed to improve efficiency (for example, for VoIP systems). The difference between the two is in the Synchronization field. The long preamble is 128 bits, and the short is 56 bits. WPA2 It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i amendment to the 802.11 standard. Temporal Key Integrity Protocol (TKIP) The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryption standard for wireless LANs. TKIP is the next generation of WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a message integrity check and a re-keying mechanism, thus fixing the flaws of WEP. 802.1x Authentication 802.1x is a framework for authenticated MAC-level access control, defines Extensible Authentication Protocol (EAP) over LANs (WAPOL). The standard encapsulates and leverages much of EAP, which was defined for dial-up authentication with Point-to-

Point Protocol in RFC 2284. Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL messages that convey the shared key information critical for wireless security.
