Digital Mobility Controller 320/321 (DMC 320/321)
The two levels of controllers allow customers to start small and grow their mobility solution to meet their needs
today and tomorrow without being charged for additional equipment until the need arises.
The DMC 080/081 will support up to eight handsets and two base stations. Two DMC 080/081 modules can be
linked together, if incremental growth is required (2 DMC 080/081 linked together will support 4 base stations
and 16 handsets). The DMC 320/321 will support 32 handsets and 8 base stations. The DMC 320/321 can also
be linked to expand up to 64 handsets and 16 base stations.
The DMC module provides power to each base station via twisted pair cable. The base station can be located up
to 4921 feet (1500 m) from the DMC module. The two-channel repeater is used to extend coverage from a base
station, up to 50% additional coverage. Up to six repeaters can be registered to a specific base station to
extend the range of a base station. The repeaters are linked to the base station in a wireless manner, so that
no physical connection is required. Local power is required for each repeater.
The solution does offer an external antenna which can be used in conjunction with a repeater to extend a base
station signal up to 0.62 miles (1 km) away. A typical application would be a campus with multiple buildings
requiring coverage.

Digital Mobility Base Stations
Each Digital Mobility base station supports up to four simultaneous calls and provides up to 5,000 square
meters of coverage (depending on environment). One base station can support up to six repeaters to further
extend the Digital Mobility coverage.
