6.2 Wireless LAN Basics

This section describes the wireless LAN network terms.

6.2.1 Channel

A channel is the radio frequency(ies) used by IEEE 802.11b wireless devices. Channels

available depend on your geographical area. You may have a choice of channels (for your

region) so you should use a different channel than an adjacent AP (access point) to reduce

interference. Interference occurs when radio signals from different access points overlap

causing interference and degrading performance.

Adjacent channels partially overlap however. To avoid interference due to overlap, your AP

should be on a channel at least five channels away from a channel that an adjacent AP is using.

For example, if your region has 11 channels and an adjacent AP is using channel 1, then you

need to select a channel between 6 or 11.

6.2.2 SSID

The SSID (Service Set Identity) is a unique name shared among all wireless devices in a

wireless network. Wireless devices must have the same SSID to communicate with each other.
