Wireless Basics
Using radio frequency (RF) technology, WLANs transmit and receive data
over the air, minimizing the need for wired connections. Thus, WLANs
combine data connectivity with user mobility, and, through simplified
configuration, enable movable LANs.
• Installation Speed and Simplicity - Installing a wireless LAN system can
be fast and easy and can eliminate the need to pull cable through walls
and ceilings.
• Installation Flexibility - Wireless technology allows the network to go
where wires cannot go.
• Reduced Cost-of-Ownership - While the initial investment required for
wireless LAN hardware might be higher than the cost of wired LAN
hardware, overall installation expenses and life-cycle costs will be
significantly lower. Long-term cost benefits are greatest in dynamic
environments requiring frequent moves, adds, and changes.
• Scalability - Wireless LAN systems can be configured in a variety of
topologies to meet the needs of 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 that allows roaming over a broad area.
