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 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.
