What is Wireless LAN?

Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired sys-

tems. WLANs are flexible and easy to setup and manage. They are also more economical than wired LAN

systems.

Using radio frequency (RF) technology, WLANs transmit and receive 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 organiza-

tion, 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: WLANs 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.
