operations - does not use congested

UHF or VHF bands

• 10 wireless beltpacks in 1RU

• Point-to-point and small group

wireless communications

• Up to 6 communications routes per

beltpack

• Create custom coverage zones with

up to 10 remote antennas

• Locate active antennas up to

1,000 metres (3,200 feet) from base

• Create 5-character labels for each

beltpack and connector

• Customize, name, and assign groups

• Two party-line and ve 4-wire

connectors

• Party-line call-alerting functionality

with beltpack vibration

• Frequency and channel-hopping

technology automatically nds clear

spectrum

• Base functions like a digital matrix;

each beltpack has a “virtual port”

timeslot

registered to a particular base

• Beltpack battery monitors displayed

on base station

Connectivity with Wired

Communications

There are 4-wire and party-line intercom

connectivity on the rear panel of the

CellCom10, providing communication

with other wired intercom systems. Two

party-line connectors, with loop-through,

are provided. In addition, ve 4-wire

connections can be used along with the

party-lines. Transformer-isolated input/

output for 4-wires as well as

program input and stage announce output.

CellCom Active Antenna

The connection between the CellCom

wireless beltpacks and the base station is

made through the Active Antennas. Unlike

other wireless intercom systems, where

the receive and transmit functions are in

the base, CellCom places that function

within the Active Antennas.

Each Active Antenna supports up to ve

full duplex wireless connections with

CellCom beltpacks in one coverage area.

To support more than 5 beltpacks in a

particular area, co-locate another Active

Antenna. The omnidirectional coverage

area may be up to 250 metres (800 feet)

in radius, though typical distances in

production environments range from

approximately 50 to 200 metres.

Multiple Active Antennas may be used with

the system. 4-pair screened CAT-5 cable

is used to connect the Active Antennas

either directly to the 2 antenna ports on the

base, or via a 5-way splitter unit. Antennas

may be located up to 1,000 metres (3,200

feet) away with local power or 250m when

centrally powered from the base station.

Distributed Coverage

The CellCom10 base station will support

up to 10 Active Antennas co-located in one

area. By overlapping the individual antenna

coverage zones from multiple Active

Antennas, large and seamless customised

wireless coverage may be achieved.

With CellCom10, coverage areas that

were almost impossible to achieve with

conventional wireless are now possible.

Active Antennas can be placed into areas

that are structurally shielded from one

another, allowing wireless beltpacks to

go between without losing connection.

A coverage zone can be located far

from the base, allowing a wireless

user to operate there as part of the

communications network.

The Antenna Splitter gives an additional

level of exibility, so that a single CAT-5

cable may run to it – and then fanning

out to up to 5 Active Antennas. With the

two antenna ports on the CellCom10

base going to two splitters, the 10 Active

Antennas provide extensive coverage.
