SpectraLink Corporation
Installation and Operation
Link WTS – Link 150 M3 MCU
The MCU supports four Base Stations and up to 16 Wireless Telephones. Up to four
Link 150 MCUs can be linked together for extended coverage area. Chained MCUs
support up to 64 Wireless Telephones maximum.
SpectraLink offers an analog MCU that works with telephone systems (CO, PBX or
Key Systems) with analog (loop start) ports. We also offer digital MCUs that work
with the most common 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-premises 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.)
