Wireless Networking Basics D-7

Note: Whatever keys you enter for an AP, you must also enter the same keys for the client adapter

in the same order. In other words, WEP key 1 on the AP must match WEP key 1 on the client

adapter, WEP key 2 on the AP must match WEP key 2 on the client adapter, etc.

Note: The AP and the client adapters can have different default WEP Keys as long as the keys are

in the same order. In other words, the AP can use WEP key 2 as its default key to transmit while a

client adapter can use WEP key 3 as its default key to transmit. The two devices will communicate

as long as the AP’s WEP key 2 is the same as the client’s WEP key 2 and the AP’s WEP key 3 is

the same as the client’s WEP key 3.

Wireless Channels

IEEE 802.11 wireless nodes communicate with each other using radio frequency signals in the

ISM (Industrial, Scientific, and Medical) band between 2.4 GHz and 2.5 GHz. Neighboring

channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending

signals using a particular channel will utilize frequency spectrum 12.5 MHz above and below the

center channel frequency. As a result, two separate wireless networks using neighboring channels

(for example, channel 1 and channel 2) in the same general vicinity will interfere with each other.

Applying two channels that allow the maximum channel separation will decrease the amount of

channel crosstalk, and provide a noticeable performance increase over networks with minimal

channel separation.
