offer digital MCUs that work with certain brands of telephone systems' (PBX or key
systems) digital ports.
•
Base Stations – act as a radio transceiver to provide the communications signal
between the wireless telephone and the MCU. Base Stations are slightly larger than a
smoke detector and are typically mounted on the ceiling, in strategic locations
throughout the facility. A single Base Station can provide radio coverage for an area
of 5,000 to 50,000 square feet depending on building obstructions. Base Stations may
be located up to 2,200 cable feet from the MCU.
When a wireless telephone user makes or receives a call, the wireless telephone and
Base Station establish a digital radio communication link. As the user moves around
the coverage area, calls are “handed off” to the Base Station that is able to provide the
best radio signal (typically the closest Base Station). These handoffs involve the
wireless telephone establishing a communication link with another Base Station and
dropping the previous link.
•
Link Wireless Telephones – communicate with the Base Station using digital spread
spectrum transmission at 902-928 MHz. Employees can carry wireless telephones to
keep in contact as they move throughout the building. The wireless telephones use
on-premise wireless technology; they are not cellular or satellite phones. They are
connected to the facility's existing telephone system and, just like wired telephones,
can receive calls directly, receive transferred calls, transfer calls to other extensions,
and make outside and long distance calls (subject to the restrictions applied in your
facility.)
