Base Stations provide the wireless communication channel between the Wireless Telephone and the MCU. Each Base Station supports four simultaneous telephone calls and covers a transmission area of typically 25 to 45 thousand square feet. The size of the coverage area is dependent on wall structure, ceiling height, and other obstructions within a building.----A telephone call is passed from one Base Station to another as a user walks throughout the coverage area. The Link Wireless Telephone System is designed to provide seamless coverage, enabling smooth hand off of active calls. ----Base Stations are small, about the size of a hardback book, and can be mounted under a drop ceiling or on the wall. For outdoor installations, a weather proof enclosure is available.
