The Wireless Local Area Network is a flexible data communication system being implemented as an extension to or as on alternative for, a Wired Local Area Networking within a building or campus.
Using electromagnetic waves, WLAN’s transmit and receive data over the air, minimizing the need for wired connections. Thus, it combines data connectivity with user mobility and through simplified configuration enables movable LANS.
However, WLANS frequently augmenting rather than replacing wired networks. It is providing the final few meters connectivity between a backbone network and the mobile user. The power and flexibility of Wireless Local Area Networking finds application both in the office as well as in home environments.
It is also being used in consulting and sales, manufacturing, warehousing, corporate office, education, banking and also health care.
ADVERTISEMENTS:
The benefits of wireless LANS over traditional wired networks are due to several factors like of its mobility, speed, simplicity installation facility, reduced cost of ownership, spread spectrum etc.
