1. What is a Wireless LAN ?

Wireless LANs provide all the functionality of wired LANs, without the need for physical connections

(wires). Data is modulated onto a radio frequency carrier and transmitted through the ether. Typical bit-

rates are 11Mbps and 54Mbps, although in practice data throughput is half of this. Wireless LANs can

be formed simply by equipping PC's with wireless NICs. If connectivity to a wired LAN is required an
