Wireless LAN Technology Overview
Technology overview
A wireless local area network (LAN) is a flexible data communications system
implemented as an extension to, or as an alternative for, a wired LAN. Using radio
frequency (RF) technology, wireless LANs transmit and receive data over the air,
minimizing the need for wired connections. Thus, wireless LANs combine data
connectivity with user mobility.
Wireless LANs have gained strong popularity in a number of vertical markets,
including the health-care, retail, manufacturing, warehousing, and academia.
These industries have profited from the productivity gains of using hand-held
terminals and notebook computers to transmit real-time information to centralized
hosts for processing. Today wireless LANs is becoming more widely recognized as a
general-purpose connectivity alternative for a broad range of business customers
in home and office.
