User's Manual

Networking in that it includes an access point. Unlike the ad-hoc
structure where users on the LAN contend the shared
bandwidth, on an infrastructure network the access
point can manage the bandwidth to maximize bandwidth
utilization.
Additionally, the access point enables users on a
wireless LAN to access an existing wired network,
allowing wireless users to take advantage of the wired
networks resources, such as Internet, email, file
transfer, and printer sharing.
Infrastructure networking has the following advantages
over ad-hoc networking:
•
Extended range: each wireless LAN computer
within the range of the access point can
communicate with other wireless LAN computers
within range of the access point.
• Roaming: the access point enables a wireless LAN
computer to move through a building and still be
connected to the LAN.
•
Wired to wireless LAN connectivity: the access
point bridges the gap between wireless LANs and
their wired counterparts.
Notes on Wireless LAN Configuration
When configuring a wireless LAN (WLAN), be sure to note the following
points:
• Optimize the performance of the WLAN by ensuring that the distance
between access points is not too far. In most buildings, WLAN Adapters
operate within a range of 100 ~ 300 feet, depending on the thickness
and structure of the walls.
• Radio waves can pass through walls and glass but not metal. If there is
interference in transmitting through a wall, it may be that the wall has
reinforcing metal in its structure. Install another access point to
circumvent this problem.
• Floors usually have metal girders and metal reinforcing struts that
interfere with WLAN transmission.
This concludes the first chapter. The next chapter deals with the hardware
installation of the Adapter.
