to ensure that there's adequate coverage and the APs are operating properly. You can
use the AP's built-in tests; for example, carrier tests scan the frequency band and
make recommendations on which channels to use to avoid interference.
Most APs come with default factory settings that are adequate for most situations,
assuming your APs and radio cards are from the same vendor. If necessary, you can
change the settings from a PC by accessing the individual APs by IP address using
telnet or a browser. For example, you might want to activate optional href="http://www.itworld.com/Net/2629/ITW1844/">encryption. For
most optional features to work properly, you must activate them on all access points
and radio cards.
Next time, we'll take a close look at what's on the horizon: orthogonal frequency
division multiplexing (OFDM).
