See next page fordescriptions on each setting.IMPORTANT: New settings will only take effect after clicking the “Fin-ish” button and waiting for the SpaceLink Home Gateway to restart.
3. Utilities34 SpaceLink Home GatewayChapter 3 - Home Gateway UtilitiesSSID & ChannelThe SSID is an identification string of up to 32 ASCII characters thatdifferentiate 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 SpaceLinkHome Gateway or Access Point is deployed in the same area. In that case, youshould use a different SSID and radio channel for each SpaceLink HomeGateway or Access Point. All the SpaceLink Home Gateways and SpaceLink802.11b client adapters must have the same SSID to allow a wireless mobileclient to roam between the SpaceLink Home Gateways. By default, theSSID is set to “default”.ChannelIEEE 802.11b devices are direct sequence spread spectrum devices thatspread a radio signal over a range of frequencies. The range of frequenciesused by a direct sequence device is called a Channel.The IEEE 802.11b specification supports up to 14 overlapping Channelsfor radio communication. But only 11 Channels are supported in the UnitedStates and therefore on the SpaceLink Home Gateway. To minimizeinterference, configure each the SpaceLink Home Gateway to use Non-overlapping channels. Non-overlapping channels have 25Mhz separationbeginning at the first allowed channel for the country (for the US and mostof 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 sitesurvey utility in the SpaceLink PC card or CF card setup CD.Basic Data RateSelect “1, 2, 5.5 & 11Mbps” to maximize performance. Use “1 & 2 Mbps”only when backward compatibility is needed for some older wireless LANcards 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 furtheraway from the SpaceLink Home Gateway, the data rate automatically decreasesin order to maintain a usable radio connection. Therefore, a client that is closeto an the SpaceLink Home Gateway may operate at 11 Mbps, but a client thatis far away from the SpaceLink Home Gateway may operate at 2 Mbps.
3. UtilitiesSpaceLink Home Gateway 35Chapter 3 - Home Gateway UtilitiesSupported Clients802.11b products can operate at 11 Mbps, 5.5 Mbps, 2 Mbps or 1 Mbps. Thisallows 802.11b devices to communicate with any existing 802.11 direct sequencedevices that operate only at 1 or 2 Mbps. By default, the SpaceLink Home Gatewaywill support both 802.11b and 2 Mbps 802.11 direct sequence clients.WEPThe IEEE 802.11b standard specifies an optional encryption feature, knownas Wired Equivalent Privacy or WEP, that is designed to provide a wirelessLAN 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 802.11bnetwork using either a 64-bit or 128-bit encryption algorithm. In addition,WEP is also used in conjunction with the optional Shared KeyAuthentication algorithm to prevent unauthorized devices from associatingwith an 802.11b network.Enabling WEP can protect your data from eavesdroppers. If you do notneed this feature, select “no” to skip the following setting. The SpaceLinkHome Gateway supports both 64-bit and 128-bit encryption using the WiredEquivalent Privacy (WEP) algorithm. Select the type of encryption youwant 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 40/104bitsYou may be confused about configuring WEP encryption, especially whenusing multiple wireless LAN products from different vendors. There aretwo levels of WEP Encryption: 64 bits and 128 bits.Firstly, 64 bit WEP and 40 bit WEP are the same encryption method andcan interoperate in the wireless network. This lower level of WEP encryptionuses 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 64bits (40 + 24). Some vendors refer to this level of WEP as 40 bits andothers refer to this as 64 bits. ASUS SpaceLink products use the term 64bits when referring to this lower level of encryption.Secondly, 104 bit WEP and 128 bit WEP are the same encryption methodand can interoperate in the wireless network. This higher level of WEPencryption 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
3. Utilities36 SpaceLink Home GatewayChapter 3 - Home Gateway Utilitiesmakes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104bits and others refer to this as 128 bits. ASUS SpaceLink products use theterm 128 bits when referring to this higher level of encryption.Magic Word & GenerateAutomatically generate four WEP keys. A WEP key is either 10 or 26hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64 bitor 128 bit in the WEP pull-down menu. Type a combination of up to 64letters, numbers, or symbols in the Magic Word column, then the SpaceLinkHome Gateway Manager uses an algorithm to generate four WEP keys forencryption. If you want to type in the keys manually, leave this field blank.The SpaceLink family of products all use the same algorithm to generatethe keys so that they can all use the same WEP key.Note: This function eases users from having to remember theirpasswords and is compatible to ASUS SpaceLink family of prod-ucts. But this is not as secure as manual assignment.WEP KeyAt most four keys can be set. A WEP key is either 10 or 26 hexadecimaldigits (0~9, a~f, and A~F) based on whether you select 64 bit or 128 bit inthe WEP pull-down menu. The home gateway and ALL of its wireless clientsMUST have at least the same default key.Default KeyThe Default Key field lets you specify which of the four encryption keysyou use to transmit data on your wireless LAN. As long as the SpaceLinkHome Gateway or wireless mobile client with which you are communicatinghas the same key in the same position, you can use any of the keys as thedefault key. If the home gateway and ALL of its wireless clients use thesame four WEP keys, select “key rotation” to maximize security. Otherwise,choose one key in common as the default key.Authentication MethodIt is suggested to select “Shared Key Only”. If “Open System Only” or“Shared Key and Open System” is used, the home gateway may acceptconnection requests from unauthorized wireless clients.Click the “Finish” button to save your new settings and restart theSpaceLink Home Gateway or click “Save” and restart later.

4. Performance64 SpaceLink Home GatewayChapter 4 - Wireless Performance4. Wireless PerformanceThis section provides the user with ideas for how to improve the performanceof a SpaceLink 802.11b network.Site TopographyFor optimal performance, locate wireless mobile clients and the SpaceLinkHome Gateways away from transformers, heavy-duty motors, fluorescentlights, microwave ovens, refrigerators, and other industrial equipment.Signal loss can occur when metal, concrete, walls or floors blocktransmission. Locate the SpaceLink Home Gateways in open areas or addthe SpaceLink Home Gateways as needed to improve coverage.Microwave ovens operate in the same frequency band as the SpaceLinkHome Gateway. Therefore, if you use a microwave within range of theSpaceLink Home Gateway you may notice network performancedegradation. However, both your microwave and your the SpaceLink HomeGateway will continue to function.Site SurveysA site survey (utility provided with the SpaceLink PC card and CF card)analyzes the installation environment and provides users withrecommendations for equipment and its placement. The optimum placementof 11 Mbps Home Gateways differs for 1 or 2 Mbps Home Gateways,because the locations and number of Home Gateways required are different.
4. PerformanceSpaceLink Home Gateway 65Chapter 4 - Wireless PerformanceRangeEvery environment is unique with different obstacles, barriers, materials,etc. and, therefore, it is difficult to determine the exact range that will beachieved without testing. However, has developed some guidelines toestimate the range that users will see when the product is installed in theirfacility, but there are no hard and fast specifications.Radio signals may reflect off of some obstacles or be absorbed by othersdepending on their construction. For example, with two 802.11b radios,you may achieve up to 1000' in open space outdoors where two deviceshave 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 thanoperation at 11 Mbps. The SpaceLink Home Gateway will automaticallyadjust the data rate to maintain a usable radio connection.Therefore, a client that is close to the SpaceLink Home Gateway may operateat 11 Mbps while a client that is on the fringe of coverage may operate at 1Mbps. As mentioned earlier, you can configure the data rates that theSpaceLink Home Gateway will use. Note that if you limit the range of datarates available to the SpaceLink Home Gateway, you may reduce theeffective wireless range of the SpaceLink 802.11b products.

Appendix72 SpaceLink Home GatewayAppendixGlossaryAccess Point - An access point is a device that allows wireless clients toconnect to other wireless clients and it acts as a bridge between wirelessclients and a wired Ethernet network.Broadband - A type of data transmission in which a single medium (suchas cable) carries several channels of data at once.Channel - Wireless access points allows you to choose different radiochannels in the wireless spectrum. A wireless LAN device operates withinthe 2.4 GHz spectrum and a channel is within a FCC specified range, similarto any radio channel.Client - A client is the desktop or mobile PC that is connected to yournetwork.Device name - Also known as DHCP client ID or network name. Sometimesprovided by an ISP when using DHCP to assign addresses.DHCP (Dynamic Host Configuration Protocol) - This protocol allows acomputer (or many computers on your network) to be automatically assigneda single IP address from a DHCP server.DNS Server Address (Domain Name System) - DNS allows Internet hostcomputers to have a domain name and one or more IP addresses. A DNSserver keeps a database of host computers and their respective domain namesand IP addresses, so that when a user enters a domain name into the Internetbrowser, the user is sent to the proper IP address. The DNS server addressused by the computers on your home network is the location of the DNSserver your ISP has assigned.DSL Modem (Digital Subscriber Line) - A DSL modem uses your existingphone lines to transmit data at high speeds.Encryption - This provides wireless data transmissions with a level ofsecurity.ESSID (Extended Service Set Identifier) - You must have the same ESSIDentered into the gateway and each of its wireless clients. The ESSID is aunique identifier for your wireless network.Ethernet - Ethernet networks are connected by cables and hubs, and movedata around. This is a standard for computer networks.
AppendixSpaceLink Home Gateway 73AppendixFirewall - A firewall determines which information passes in and out of anetwork. NAT can create a natural firewall by hiding a local network’s IPaddresses from the Internet. A Firewall prevents anyone outside of yournetwork from accessing your computer and possibly damaging or viewingyour 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 IEEEsets standards for networking, including Ethernet LANs. IEEE standardsensure interoperability between systems of the same type.IP Address (Internet Protocol) - An IP address consists of a series of fournumbers separated by periods, that identifies a unique Internet computerhost, allowing messages intended for that computer to be delivered to thecorrect destination.ISP (Internet Service Provider) - An ISP is a business that allowsindividuals or businesses to connect to the Internet. Users log on to theInternet using an account with an ISP or Internet Service Provider. ISPscan serve IP addresses dynamically, or assign static (fixed) IP addresses toindividual computers.ISP Gateway Address - The ISP Gateway Address is an IP address for theInternet router. This address is only required when using a cable or DSLmodem.LAN (Local Area Network) - A LAN is a group of computers and devicesconnected 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 hardwareaddress of a device connected to a network.NAT (Network Address Translation) - NAT masks a local network’s groupof IP addresses from the external network, allowing a local network ofcomputers to share a single ISP account. This process allows all of thecomputers on your home network to use one IP address. This will enableaccess to the Internet from any computer on your home network withouthaving to purchase more IP addresses from your ISP.PC Card - This is an Ethernet card that connects to the PCMCIA slot onyour Notebook PC. This enables the computer to communicate with wirelessaccess points.
