LPS-20X
The LPS-20x (and the access controller) provide wireless network coverage in a radius of up to 100 meters
(300 feet). This is called a wireless cell. To maximize coverage of the cell, the LPS-20x is best installed in an open
area with as few obstructions as possible. Try to choose a location that is central to the area being served.
The LPS-20x uses radio waves in the 2.4 Ghz band to communicate with client stations. Radio waves cannot
penetrate metal, instead they are reflected. This means that the LPS-20x is able to transmit through wood or plaster
walls, and closed windows. However, the steel reinforcing found in concrete walls and floors may block
transmissions or reduce signal quality by creating reflections. This can make it difficult for a single LPS-20x to serve
users on different floors in a concrete building. Such installations will require a separate LPS-20x on each floor.
Client computers are able to move between cells (called roaming) without loosing contact with the network. This is
possible because wireless adapters automatically switch to the best available LPS-20x.
