What is Wireless LAN?
Wireless Local Area Network (WLAN) systems offer a great number of advantages over
traditional wired systems. WLAN is flexible and easy to setup and manage.
Using radio frequency (RF) technology, a WLAN transmits and receives data through the air. A
WLAN combines data connectivity with user mobility. For example, users can roam from a
conference room to their office without being disconnected from the network.
Using WLAN, users can conveniently access-shared information, and network administrators
can configure and augment networks without installing or moving network cables.
WLAN technology provides users with many convenient and cost saving features:
Mobility: WLAN provide LAN users with access to real-time
information anywhere in their organization, providing service
opportunities that are impossible with wired networks.
Ease of Installation: Installing is easy for novice and expert users alike,
eliminating the need to install network cables in walls and
ceilings.
Scalability: WLAN can be configured in a variety of topologies to adapt
to specific applications and installations. Configurations are
easily changed and range from peer-to-peer networks suitable
for a small number of users to full infrastructure networks of
thousands of users roaming over a broad area.
