Wireless networking
The term wireless networking refers to technology that enables two or more
computers to communicate using standard network protocols, but without
network cabling. Strictly speaking, any technology that does this could be
called wireless networking.
Architecture of wireless networks

Ad-hoc or peer-to-peer wireless network
An ad-hoc or peer-to-peer wireless network consists of a number of
computers each equipped with a wireless networking interface card. Each
computer can communicate directly with all of the other wireless enabled
computers.
Wireless network that can also use an access point
A wireless network can also use an access point, or base station. In this type
of network the access point acts like a hub, providing connectivity for the
wireless computers. Hub can connect or bridge the wireless LAN to a wired
LAN, allowing wireless computer access to LAN resources, such as file
servers or existing Internet Connectivity.
RANGE OF A WIRELESS NETWORK
Each access point has a finite range within which a wireless connection can
be maintained between the client computer and the access point. The actual
distance varies depending upon the environment; manufacturers typically
state both indoor and outdoor ranges to give a reasonable indication of
reliable performance.
MULTIPLE ACCESS POINT
If a single area is too large to be covered by a single access point, then
multiple access points or extension points can be used. When using multiple
