Networking 

Infrastructure networking differs from ad-hoc 
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.
