locations where installation of wiring may be impractical. Furthermore, IEEE
standardization facilitates interoperability of all WLAN devices that conform
to the 802.11a or 802.11b sets of standards.
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 allow roaming over a broad area.

Standards - Based Technology
The IEEE 802.11a standard designates that devices operate at an optimal
data rate of 54 Megabits per second. This means you will be able to transfer
large files quickly or even watch a movie in MPEG format over your network
without noticeable delays. This technology works by transmitting high-speed
digital data over a radio wave utilizing OFDM (Orthogonal Frequency
