What is a wireless local area network (WLAN)? A WLAN system, shown
in its most general form in Figure 1.1, consists of a network hardware backbone,
along with a series of detached components. These detached components
may include computer desktops, computer laptops, personal digital assistants
(PDAs), cell phones, gaming systems, security cameras, printers,
and appliances as clients. Using radio-frequency (RF) technology, the
WLAN system would then allow the clients to access local area network resources
while physically being detached from this network. At the same
time, the clients are capable of communicating with one another (typically
indirectly and through access points rather than peer-to-peer networks)
while physically being detached from one another. A WLAN system can
transmit data, video, and/or audio.
A WLAN system may be deployed as a stand-alone network or in tandem
with a wire ... read full excerpt from Wireless LAN Radios: System Definition to Transistor Design ebook
