. 1 Chapter 1 - Introduction The IEEE 802.11b Specification In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11 standard operate at a data rate of either 1 or 2 Mbps. In 1999, the IEEE created the 802.11b standard. 802.11b is essentially identical to the 802.11 standard except 802.11b provides for data rates of up to 11 Mbps for direct sequence spread spectrum devices. Under 802.11b, direct sequence devices can operate at 11 Mbps, 5.5 Mbps, 2 Mbps, or 1 Mbps. This provides interoperability with existing 802.11 direct sequence devices that operate only at 2 Mbps. Direct sequence spread spectrum devices spread a radio signal over a range of frequencies. The IEEE 802.11b specification allocates the 2.4 GHz frequency band into 14 overlapping operating Channels. Each Channel corresponds to a different set of frequencies. See the Appendix to determine the center frequency used by each Channel. If operating multiple 802.11b Home Gateways in the same vicinity, the distance between the center frequencies must be at least 25 MHz to avoid interference. Note that the Channels available to an 802.11b Home Gateway will vary from country to country. In the United States, the 802.11b standard allocates 11 operating Channels for direct sequence devices. Channels 1, 6, and 11 are independent and do not overlap with each other. To avoid interference between 802.11b Home Gateways, It is recommended that you configure the Home Gateways using only Channels 1, 6, and 11. SpaceLink Home Gateway 11 1

. I n t r o d u c t i o n Chapter 1 - Introduction Direct-Sequence Spread Spectrum Spread spectrum (broadband) uses a narrowband signal to spread the transmission over a segment of the radio frequency band or spectrum. Direct-

sequence is a spread spectrum technique where the transmitted signal is spread over a particular frequency range. The Space Link Home Gateway uses Direct-Sequence Spread Spectrum (DSSS) for radio communication. Direct-sequence systems communicate by continuously transmitting a redundant pattern of bits called a chipping sequence. Each bit of transmitted data is mapped into chips by the Home Gateway and rearranged into a pseudorandom spreading code to form the chipping sequence. The chipping sequence is combined with a transmitted data stream to produce the Home Gateway output signal. Wireless mobile clients receiving a direct-sequence transmission use the spreading code to map the chips within the chipping sequence back into bits to recreate the original data transmitted by the Home Gateway. Intercepting and decoding a direct-sequence transmission requires a predefined algorithm to associate the spreading code used by the transmitting Home Gateway to the receiving wireless mobile client. This algorithm is established by IEEE 802.11b specifications. The bit redundancy within the chipping sequence enables the receiving wireless mobile client to recreate the original data pattern, even if bits in the chipping sequence are corrupted by interference. The ratio of chips per bit is called the spreading ratio. A high spreading ratio increases the resistance of the signal to interference. A low spreading ratio increases the bandwidth available to the user. The Home Gateway uses a constant chip rate of 11Mchips/s for all data rates, but uses different modulation schemes to encode more bits per chip at the higher data rates. The Home Gateway is capable of an 11 Mbps data transmission rate, but the coverage area is less than a 1 or 2 Mbps Home Gateway since coverage area decreases as bandwidth increases. 12 SpaceLink Home Gateway n o i t c u d o r t n I

. 1 Chapter 1 - Introduction Wireless Operation The SpaceLink Home Gateway will operate as a MAC layer learning bridge and forward packets between wireless mobile clients and the Ethernet network. A wireless LAN that uses the SpaceLink Home Gateway generally consists of one or more 802.11b Access Points and one or more wireless mobile clients that have an 802.11b adapter installed. The SpaceLink Home Gateway maintains a table of MAC addresses, which it has learned are located either on the Ethernet network or on the radio network by monitoring the source address of packets it receives. For example, if the SpaceLink Home Gateway receives a packet over its radio, it creates an entry in its table for the node that sent the packet and labels the entry as a member of the radio network. The SpaceLink Home Gateway removes an entry from the table after five minutes of inactivity. When the SpaceLink Home Gateway receives a packet from the Ethernet network, it compares the packets destination address with the node addresses listed in its table. If the packets destination address is not in the table, the SpaceLink Home Gateway will forward the packet to the wireless mobile clients. If the packets destination address is listed in the table as a member of the radio network, the SpaceLink Home Gateway will forward the packet to the wireless mobile clients. If the packets destination address is listed in the table as a member of the Ethernet network, the SpaceLink Home Gateway will not forward the packet to the wireless mobile clients. The SpaceLink Home Gateway applies the same principles to determine if a packet received over its radio should be forwarded to the Ethernet network. The SpaceLink Home Gateway forwards all broadcast packets to wireless mobile clients. Given this, the SpaceLink Home Gateway can only support 250 nodes. The speed available to wireless mobile clients depends on the amount of information that each client exchanges with the network because the 11 Mbps wireless bandwidth is shared will all wireless nodes.

. I n t r o d u c t i o n Chapter 1 - Introduction Roaming Between SpaceLink Gateways or APs If there are multiple SpaceLink Home Gateways or Access Points on the network, then a wireless mobile client may seamlessly roam from one the SpaceLink Home Gateway or Access Point to another. Each SpaceLink Home Gateway or Access Point creates its own wireless cell or coverage area. This is also known as a Basic Service Set (BSS). Any wireless mobile client can communicate with a particular SpaceLink Home Gateway or Access Point if it is within the SpaceLink Home Gateways or Access Points coverage area. If the cells of multiple SpaceLink Home Gateways or Access Points overlap, then the wireless mobile client may switch from one SpaceLink Home Gateway or Access Point to another as it travels throughout the facility. During the hand-off from one SpaceLink Home Gateway or Access Point to another, the wireless mobile client maintains an uninterrupted connection to the network. This is known as roaming. Multiple SpaceLink Home Gateways connected to a common Ethernet network form an Extended Service Set (ESS). All members of an Extended Service Set are configured with an ID, known as the SSID or ESSID. Wireless mobile clients must be configured with the same SSID as the SpaceLink Home Gateways or Access Points on the network; a client can only roam between the SpaceLink Home Gateways or Access Points that share the same SSID. 14 SpaceLink Home Gateway n o i t c u d o r t n I

. 1 Chapter 1 - Introduction Roaming Guidelines (SpaceLink Gateways or APs) A 802.11b PC Card can only roam between 802.11b SpaceLink Home Gateways or Access Points. All the SpaceLink Home Gateways or Access Points must have the same SSID. All computers with SpaceLink PC card or CF card adapters must have the same SSID as the Home Gateways or Access Points that they will roam between. If WEP encryption is enabled, then all the SpaceLink Home Gateways or Access Points and client adapters must use the same encryption level and WEP Key(s) to communicate. The SpaceLink Home Gateways or Access Points cells must overlap to ensure that there are no gaps in coverage and to ensure that the roaming client will always have a connection available. The SpaceLink Home Gateways or Access Points that use the same Channel should be installed as far away from each other as possible to reduce potential interference. It is strongly recommended that you perform a site survey using the utility provided with the SpaceLink PC card or CF card to determine the best location for each the SpaceLink Home Gateway or Access Points in the facility. SpaceLink Home Gateway 15 Chapter 1 - Introduction SpaceLink Home Gateway Topology There are three major ways to deploy the home gateway in your local network (I) Network backbone, (II) Agent to ISP and (III) Agent to another network. 1

. 2 Chapter 2 - Installation Configuring the SpaceLink Home Gateway The home gateway can be configured to meet various usage scenarios. Some of the factory default settings may suit your usage; however, others may need changing. Prior to using the home gateway, you must check the basic settings to guarantee it will work in your environment. Configuring the SpaceLink Home Gateway is done through a web browser. You need a Notebook PC or desktop PC connected to the SpaceLink Home Gateway and running a web browser as a configuration terminal. The connection can be wired or wireless. For the wireless connection, you need an IEEE 802.11b compatible device, e.g. ASUS SpaceLink PC Card, installed in your Notebook PC. You should also disable WEP and set the SSID to default for your wireless LAN device. If you want to configure the SpaceLink Home Gateway or want to access the Internet through the SpaceLink Home Gateway, TCP/IP settings must be correct. Normally, the TCP/IP setting should be on the IP subnet of the SpaceLink Home Gateway. The SpaceLink Home Gateway incorporates a DHCP server so the easiest method is to set your PC to get its IP address automatically and reboot your computer. So the correct IP address, gateway, DNS (Domain Name System Server) can be obtained from the SpaceLink Home Gateway. Note: Before rebooting your PC, the SpaceLink Home Gateway should be switched ON and in ready state. Advanced IP Settings If you want to set your IP address manually, the following default settings of the SpaceLink Home Gateway should be known:

IP address 192.168.123.1 Subnet Mask 255.255.255.0. If you set your computers IP manually, it needs to be on the same segment. For example:

IP address 192.168.123.xxx (xxx can be any number between 2 and 254 that is not used by another device) Subnet Mask 255.255.255.0 (same as the SpaceLink Home Gateway ) Gateway 192.168.123.1 (this is the SpaceLink Home Gateway IP address) DNS 192.168.123.1 (SpaceLink Home Gateway IP address or your own).

. U t i l i t i e s Chapter 3 - Home Gateway Utilities SSID & Channel The SSID is an identification string of up to 32 ASCII characters that differentiate one SpaceLink Home Gateway or Access Point from another. The SSID is also referred to as the ESSID or Extended Service Set ID. You can use the default SSID and radio channel unless more than one SpaceLink Home Gateway or Access Point is deployed in the same area. In that case, you should use a different SSID and radio channel for each SpaceLink Home Gateway or Access Point. All the SpaceLink Home Gateways and SpaceLink 802.11b client adapters must have the same SSID to allow a wireless mobile client to roam between the SpaceLink Home Gateways. By default, the SSID is set to default. Channel IEEE 802.11b devices are direct sequence spread spectrum devices that spread a radio signal over a range of frequencies. The range of frequencies used by a direct sequence device is called a Channel. The IEEE 802.11b specification supports up to 14 overlapping Channels for radio communication. But only 11 Channels are supported in the United States and therefore on the SpaceLink Home Gateway. To minimize interference, configure each the SpaceLink Home Gateway to use Non-

overlapping channels. Non-overlapping channels have 25Mhz separation beginning at the first allowed channel for the country (for the US and most of Europe, channels 1, 6 & 11 are used). Make sure that the SpaceLink Home Gateways sharing the same Channel

(or Channels close in number) are as far away from each other as possible, based on the results of your site survey of the facility. You can find the site survey utility in the SpaceLink PC card or CF card setup CD. Basic Data Rate Select 1, 2, 5.5 & 11Mbps to maximize performance. Use 1 & 2 Mbps only when backward compatibility is needed for some older wireless LAN cards with a maximum bit rate of 2Mbps. The IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5 Mbps, 2 Mbps, and 1 Mbps. As a wireless mobile client travels further and further away from the SpaceLink Home Gateway, the data rate automatically decreases in order to maintain a usable radio connection. Therefore, a client that is close to an the SpaceLink Home Gateway may operate at 11 Mbps, but a client that is far away from the SpaceLink Home Gateway may operate at 2 Mbps. 34 SpaceLink Home Gateway Chapter 3 - Home Gateway Utilities Supported Clients 802.11b products can operate at 11 Mbps, 5.5 Mbps, 2 Mbps or 1 Mbps. This allows 802.11b devices to communicate with any existing 802.11 direct sequence devices that operate only at 1 or 2 Mbps. By default, the SpaceLink Home Gateway will support both 802.11b and 2 Mbps 802.11 direct sequence clients. WEP The IEEE 802.11b standard specifies an optional encryption feature, known as Wired Equivalent Privacy or WEP, that is designed to provide a wireless LAN with a security level equal to what is found on a wired Ethernet network. WEP encrypts the data portion of each packet exchanged on the 802.11b network using either a 64-bit or 128-bit encryption algorithm. In addition, WEP is also used in conjunction with the optional Shared Key Authentication algorithm to prevent unauthorized devices from associating with an 802.11b network. Enabling WEP can protect your data from eavesdroppers. If you do not need this feature, select no to skip the following setting. The SpaceLink Home Gateway supports both 64-bit and 128-bit encryption using the Wired Equivalent Privacy (WEP) algorithm. Select the type of encryption you want to use (64 or 128 bit) and configure one to four WEP Keys. The 128-

bit method is more secure than the 64-bit. 64/128bits versus 40/104bits You may be confused about configuring WEP encryption, especially when using multiple wireless LAN products from different vendors. There are two levels of WEP Encryption: 64 bits and 128 bits. Firstly, 64 bit WEP and 40 bit WEP are the same encryption method and can interoperate in the wireless network. This lower level of WEP encryption uses a 40 bit (10 Hex character) as a secret key (set by user), and a 24 bit Initialization Vector (not under user control). This together makes 64 bits (40 + 24). Some vendors refer to this level of WEP as 40 bits and others refer to this as 64 bits. ASUS SpaceLink products use the term 64 bits when referring to this lower level of encryption. Secondly, 104 bit WEP and 128 bit WEP are the same encryption method and can interoperate in the wireless network. This higher level of WEP encryption uses a 104 bit (26 Hex character) as a secret key (set by user), and a 24 bit Initialization Vector (not under user control). This together s e i t i l i t U

. 3 SpaceLink Home Gateway 35 3

. U t i l i t i e s Chapter 3 - Home Gateway Utilities makes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104 bits and others refer to this as 128 bits. ASUS SpaceLink products use the term 128 bits when referring to this higher level of encryption. Magic Word & Generate Automatically generate four WEP keys. A WEP key is either 10 or 26 hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64 bit or 128 bit in the WEP pull-down menu. Type a combination of up to 64 letters, numbers, or symbols in the Magic Word column, then the SpaceLink Home Gateway Manager uses an algorithm to generate four WEP keys for encryption. If you want to type in the keys manually, leave this field blank. The SpaceLink family of products all use the same algorithm to generate the keys so that they can all use the same WEP key. Note: This function eases users from having to remember their passwords and is compatible to ASUS SpaceLink family of prod-

ucts. But this is not as secure as manual assignment. WEP Key At most four keys can be set. A WEP key is either 10 or 26 hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64 bit or 128 bit in the WEP pull-down menu. The home gateway and ALL of its wireless clients MUST have at least the same default key. Default Key The Default Key field lets you specify which of the four encryption keys you use to transmit data on your wireless LAN. As long as the SpaceLink Home Gateway or wireless mobile client with which you are communicating has the same key in the same position, you can use any of the keys as the default key. If the home gateway and ALL of its wireless clients use the same four WEP keys, select key rotation to maximize security. Otherwise, choose one key in common as the default key. Authentication Method It is suggested to select Shared Key Only. If Open System Only or Shared Key and Open System is used, the home gateway may accept connection requests from unauthorized wireless clients.

Wireless Performance This section provides the user with ideas for how to improve the performance of a SpaceLink 802.11b network. Site Topography For optimal performance, locate wireless mobile clients and the SpaceLink Home Gateways away from transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators, and other industrial equipment. Signal loss can occur when metal, concrete, walls or floors block transmission. Locate the SpaceLink Home Gateways in open areas or add the SpaceLink Home Gateways as needed to improve coverage. Microwave ovens operate in the same frequency band as the SpaceLink Home Gateway. Therefore, if you use a microwave within range of the SpaceLink Home Gateway you may notice network performance degradation. However, both your microwave and your the SpaceLink Home Gateway will continue to function. Site Surveys A site survey (utility provided with the SpaceLink PC card and CF card) analyzes the installation environment and provides users with recommendations for equipment and its placement. The optimum placement of 11 Mbps Home Gateways differs for 1 or 2 Mbps Home Gateways, because the locations and number of Home Gateways required are different. 4

. P e r f o r m a n c e 64 SpaceLink Home Gateway Chapter 4 - Wireless Performance Range Every environment is unique with different obstacles, barriers, materials, etc. and, therefore, it is difficult to determine the exact range that will be achieved without testing. However, has developed some guidelines to estimate the range that users will see when the product is installed in their facility, but there are no hard and fast specifications. Radio signals may reflect off of some obstacles or be absorbed by others depending on their construction. For example, with two 802.11b radios, you may achieve up to 1000' in open space outdoors where two devices have a line of sight, meaning they see each other with no obstacles. However, the same two units may only achieve up to 300' of range when used indoors. The IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5 Mbps, 2 Mbps, and 1 Mbps. Operation at 1 Mbps provides greater range than operation at 11 Mbps. The SpaceLink Home Gateway will automatically adjust the data rate to maintain a usable radio connection. Therefore, a client that is close to the SpaceLink Home Gateway may operate at 11 Mbps while a client that is on the fringe of coverage may operate at 1 Mbps. As mentioned earlier, you can configure the data rates that the SpaceLink Home Gateway will use.

Broadband - A type of data transmission in which a single medium (such as cable) carries several channels of data at once. Channel - Wireless access points allows you to choose different radio channels in the wireless spectrum. A wireless LAN device operates within the 2.4 GHz spectrum and a channel is within a FCC specified range, similar to any radio channel. Client - A client is the desktop or mobile PC that is connected to your network. Device name - Also known as DHCP client ID or network name. Sometimes provided by an ISP when using DHCP to assign addresses. DHCP (Dynamic Host Configuration Protocol) - This protocol allows a computer (or many computers on your network) to be automatically assigned a single IP address from a DHCP server. DNS Server Address (Domain Name System) - DNS allows Internet host computers to have a domain name and one or more IP addresses. A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a user enters a domain name into the Internet browser, the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned. DSL Modem (Digital Subscriber Line) - A DSL modem uses your existing phone lines to transmit data at high speeds. Encryption - This provides wireless data transmissions with a level of security. ESSID (Extended Service Set Identifier) - You must have the same ESSID entered into the gateway and each of its wireless clients. The ESSID is a unique identifier for your wireless network. Ethernet - Ethernet networks are connected by cables and hubs, and move data around. This is a standard for computer networks. A p p e n d i x 72 SpaceLink Home Gateway Appendix Firewall - A firewall determines which information passes in and out of a network. NAT can create a natural firewall by hiding a local networks IP addresses from the Internet. A Firewall prevents anyone outside of your network from accessing your computer and possibly damaging or viewing your files. Gateway - A network point that manages all the data traffic of your network, as well as to the Internet and connects one network to another. IEEE - The Institute of Electrical and Electronics Engineers. The IEEE sets standards for networking, including Ethernet LANs. IEEE standards ensure interoperability between systems of the same type. IP Address (Internet Protocol) - An IP address consists of a series of four numbers separated by periods, that identifies a unique Internet computer host, allowing messages intended for that computer to be delivered to the correct destination. ISP (Internet Service Provider) - An ISP is a business that allows individuals or businesses to connect to the Internet. Users log on to the Internet using an account with an ISP or Internet Service Provider. ISPs can serve IP addresses dynamically, or assign static (fixed) IP addresses to individual computers. ISP Gateway Address - The ISP Gateway Address is an IP address for the Internet router. This address is only required when using a cable or DSL modem. LAN (Local Area Network) - A LAN is a group of computers and devices connected together in a relatively small area (such as a house or an office). Your home network is considered a LAN. MAC Address (Media Access Control) - A MAC address is the hardware address of a device connected to a network. NAT (Network Address Translation) - NAT masks a local networks group of IP addresses from the external network, allowing a local network of computers to share a single ISP account. This process allows all of the computers on your home network to use one IP address. This will enable access to the Internet from any computer on your home network without having to purchase more IP addresses from your ISP. PC Card - This is an Ethernet card that connects to the PCMCIA slot on your Notebook PC. This enables the computer to communicate with wireless access points. x i d n e p p A SpaceLink Home Gateway 73 Appendix PPP (Point-to-Point Protocol) - PPP is a protocol for communication between computers using a serial interface, typically a personal computer connected by phone line to a server. PPPoE (Point-to-Point Protocol over Ethernet) - Point-to-Point Protocol is a method of secure data transmission. PPP using Ethernet to connect to an ISP. Subnet Mask - A subnet mask is a set of four numbers configured like an IP address. It is used to create IP address numbers used only within a particular network. TCP/IP (Transmission Control Protocol/Internet Protocol) - This is the standard protocol for data transmission over the Internet. Protocols used to connect hosts on the Internet. WAN (Wide Area Network) - A system of LANs, connected together. A network that connects computers located in separate areas, (i.e., different buildings, cities, countries). The Internet is a wide area network. WECA (Wireless Ethernet Compatibility Alliance) - An industry group that certifies cross-vender interoperability and compatibility of IEEE 802.11b wireless networking products and to promote that standard for enterprise, small business, and home environments. WLAN (Wireless Local Area Network) - This is a group of computers and other devices connected wirelessly in a small area. A wireless network is referred to as LAN or WLAN.
