WLAN - the new world of wireless communication

Another term for WLAN (Wireless Local Area Network) is also 'WiFi'. In both cases, it is a method of wireless data transmission in a local area. The range of a WLAN depends on the radiation power and the type of environment. The domestic transmission power in Germany is between 100 and 500 mW and thus covers an area of 30 to 100 meters, whereby damp concrete walls, for example, can considerably attenuate the transmission. The performance of WLAN networks can be significantly increased with directional antennas. With a clear line of sight, distances of up to 100 km can be bridged.
