bandwidth utilization. Additionally, the Access Point enables 
users on a wireless LAN to access an existing wired network, 
allowing wireless users to take advantage of the wired 
networks resources, such as Internet, email, file transfer, and 
printer sharing. The scale and range of the Infrastructure 
networking are larger and wider than that of the Ad-hoc 
networking. 
 
 
The range of radio frequencies used by IEEE 802.11g wireless 
devices is called a “channel”. 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.
 
 
 
For some European Country, it may have its own domain; 
users are responsible for ensuring that the channel set 
configuration is in compliance with the regulatory standards of 
these countries.
