• 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.
This concludes the first chapter. The next chapter deals with the hardware installation of the Wireless LAN card.
