If the wireless network is relatively small and needs to share resources only 
with the other computers on the wireless network, then the ad-hoc mode can 
be used. Ad-hoc mode allows computers equipped with wireless 
transmitters and receivers to communicate directly with each other, eliminating  
the need for an access point. The drawback of this mode is that, in Ad- 
Hoc mode, wireless-equipped computers are not able to communicate with 
computers on a wired network. And, of course, communication between the 
wireless-equipped computers is limited by the distance and interference directly  
between them.
 
 
Chapter 2: Planning Your 
Wireless 
Network 
A wireless local area network (WLAN) is exactly like a regular local area 
network 
(LAN), except that each computer in the WLAN uses a wireless device to 
connect to the network. Computers in a WLAN share the same frequency 
channel and SSID, which is an identification name for wireless devices. 
Unlike wired networks, wireless networks have two different modes in which 
they may be set up: infrastructure and ad-hoc . An infrastructure configuration 
is a WLAN and wired LAN communicating to each other through an 
access point. An ad -hoc configuration is wireless-equipped computers 
communicating 
directly with each other. Choosing between these two modes  
depends on whether or not the wireless network needs to share data or 
peripherals  
with a wired network or not. 
If the computers on the 
wireless network need to  
be accessed by a wired 
network or need to share a  
peripheral, such as a printer, 
with the wired network 
computers, the wireless
