What is Wireless LAN?
Wireless Local Area Network (WLAN) systems offer a great num-
ber of advantages over traditional wired systems. WLANs are
flexible and easy to setup and manage. They are also more eco-
nomical than wired LAN systems.
Using radio frequency (RF) technology, WLANs transmit and re-
ceive data through the air. WLANs combine data connectivity with
user mobility. For example, users can roam from a conference
room to their office without being disconnected from the LAN.
Using WLANs, 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: WLANs provide LAN users with access to real-
time information anywhere in their organization, providing
service opportunities that are impossible with wired net-
works.
