Chapter 3SpaceLink Access Point 31Chapter 3 - SpaceLink Access Point ManagerChannelIEEE 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 Access Point. To minimizeinterference, configure each SpaceLink Access Point 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 Access Points sharing the same Channel (orChannels 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.Supported RatesThe IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5Mbps, 2 Mbps, and 1 Mbps. As a wireless mobile client travels further andfurther away from the SpaceLink Access Point, the data rate automaticallydecreases in order to maintain a usable radio connection. Therefore, a clientthat is close to an SpaceLink Access Point may operate at 11 Mbps, but aclient that is far away from the SpaceLink Access Point may operate at 2Mbps. By default, the SpaceLink Access Point supports all four data rates.However, you can specify a data rate by checking the appropriate box.Supported 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 Access Pointwill support both 802.11b and 2 Mbps 802.11 direct sequence clients.Encryption (Button)Click this button to open the Encryption page.Advanced (Button)Click this button to open the advanced settings page.
