802.11 Wireless LAN
Provides network connectivity over wireless media
An Access Point (AP) is installed to act as Bridge between Wireless and Wired Network
The AP is connected to wired network and is equipped with antennae to provide wireless connectivity
Range ( Distance between Access Point and WLAN client) depends on structural hindrances and RF gain of the antenna at the Access Point
To service larger areas, multiple APs may be installed with a 20-30% overlap
A client is always associated with one AP and when the client moves closer to another AP, it associates with the new AP (Hand-Off)
Three flavors:
802.11b
802.11a
802.11g
