What is Wireless LAN?
Wireless Local Area Network (WLAN) systems offer a great
number 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 confer-
ence 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.
•
Ease of Installation: Installing is easy for novice and ex-
pert users alike, eliminating the need to install network
cables in walls and ceilings.
•
Scalability : WLANs can be configured in a variety of to-
pologies 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.
