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 cards operate within a range of 100 ~ 300 feet, depending on the thick-
ness 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.
