Nortel Digital Mobility
Basestation
Basestation
The Digital Mobility Basestation controls
the traffic channels in the air and works
as a link between the Digital Mobility
Handset and the Digital Mobility
Controller (DMC). The DMC operates
the Basestations through a wired standard
twisted pair of cables. Only one pair is
required per Basestation and the cable
length may be up to 1,500 meters
(4,921 feet). Nortel recommends using
CAT5 wiring.

Each Basestation covers a circular area
of radius up to 450 meters (1,476 feet).
In a typical office environment, the
radius is 50-150 meters (164-492 feet)
depending on the environment. It is not
possible to define a more exact size of a
Basestation coverage area, as it depends
on location specifics such as building
materials, etc. Before a Digital Mobility
solution is installed, careful deployment
is performed in order to define how
many Basestations are needed to provide
the necessary coverage at each individual
location.

Nortel Digital Mobility
Repeater
Repeater
The Digital Mobility Repeater is a
building block to be used to extend the
coverage area in a Digital Mobility
solution. The Repeater does not increase
the number of traffic channels, but
provides a larger physical spreading of
the traffic channels and thereby increases
the coverage area established with the
Digital Mobility Basestations. The
Repeater extends the coverage of the
Digital Mobility Basestation by 50
percent. Repeaters are mainly used in
areas with limited traffic.

Repeater Jumps
The Digital Mobility Repeaters can be
installed like “pearls on a string” to
provide coverage in a large area using
only Digital Mobility Repeaters. A
maximum of three Repeaters 20 can be
placed on the string, providing the
possibility to assure coverage of a large
area without physical cabling. Repeater
jumps should only be used to expand
coverage in areas with limited traffic as
the total area will have to share two
traffic channels.

External Antenna
External Antenna
The Digital Mobility Repeater with two
voice channels can be supplied with an
external directional antenna, which makes
it possible to create radio coverage in a
remote area without cabling to the rest
of the installation. The use of an external
directional antenna makes it possible for
businesses encompassing more than one
building to still maintain coverage in all
areas. This could be the case in a motel,
where the reception area is placed in one
building and the rooms are in another.
