What is Wireless
Wireless Local Area Network (WLAN)
is an IEEE 802.11 standard on wireless data transmission.
It uses radio frequency to replace tradition
network built on CAT5 or coaxial cabling.
Function and advantages
WLAN eliminates the problem
of cablings and routine check-up on cables. This
also saves costs on re-cabling during a business
expansion or relocation.
Distribution System is like a bridging device
for wireless network. A typical access point
can only take the role of either send or receive.
When building a large wireless network, or to
cover a larger area, you will need more access
points. WDS can be used to act as both sending
and receiving. This adds flexibility when the
coverage area is large. However, the channel
used between access points must be the same.
When access points increases, the number of available
channels decreases. It may not be a good solution
for schools or environment with many users.
