Notes on Wireless LAN Configuration
When configuring a wireless LAN (WLAN), take note of the following points:
❑Start by determining the areas to be networked, the number of users and the type of devices to be used. Then determine the number of Access Points required and where they should be placed.
❑An Access Point provides a data rate of up to 11 Mbps, which is shared by all wireless clients in the area covered by the Access Point. If two Access Points are placed close to each other, they can simultaneously provide a data rate of up to 22 Mbps. However, they must operate in
❑Optimize the performance of the WLAN by ensuring that the distance between two Access Points is not too large. In most buildings, WLAN cards operate within a range of 100 to 300 feet (30 to 91 meters), depending on the thickness and structure of the walls. Under normal conditions, an Access Point provides a coverage of up to 150 feet (46 meters). However, in offices with walls or cube walls, the coverage is only around 80 feet (24 meters).
❑Radio waves can pass through walls and glass but not metal. If the signal on the other side of a wall is weak, it may be that the wall has reinforcing metal in its structure. Install another Access Point to circumvent this problem or move the Access Point to another location.
❑Floors usually have metal girders and metal reinforcing struts that weaken radio waves.
