What is the transmission coverage of WLAN products?
Radio Frequency (RF) average range, especially in indoor environments, is a function of product design, including transmitted power and receiver design, interference, and propagation path. Interactions with typical building objects, including walls, metal, and even people, can affect how energy propagates, and thus what range and coverage a particular system achieves. Wireless LAN systems use RF because radio waves can penetrate many indoor walls and surfaces. The range or radius of coverage for typical WLAN systems varies up to 450 feet (150 meters, in open environment) depending on the number and types of obstacles encountered. Coverage can be extended, and freedom of true mobility and roaming can be provided for a greater area through the use of multiple access points.
