CELLCOM 10 WIRELESS COMMUNICATION SYSTEM 1-1
GETTING STARTED: AN
INTRODUCTION TO CELLCOM 10
With a CellCom 10 wireless beltpack you can roam freely around a studio or
production facility while talking and listening to all, or selected, members of the
production team. With its six communication routes, the beltpack gives you the
flexibility to communicate quickly and seamlessly with individuals or groups,
and to change communication routes as often as needed.
CellCom 10™ is the North American name for the award-winning FreeSpeak®
technology, the world’s first wireless system to include local route programming,
crosspoint level control, assignment of IFBs, groups, and full non-blocking
mixing facilities.
In the United States the system operates in the unlicensed 1.92 GHz to 1.93
GHz band. With its unique and innovative digital technology, which continually
searches for unused radio frequency (RF) channels, CellCom avoids the noise
and interference issues associated with traditional wireless systems using
congested UHF and VHF bands.
Figure 1: A CellCom 10 Antenna, Beltpack, and Base Station
CellCom 10 allows you to set up a wireless system specifically tailored to your
needs, by locating antennas and beltpacks in areas where they are needed most.
And because the beltpacks operate in the unlicensed 1.92 to 1.93 GHz
frequency spectrum, there is no interference with existing wireless systems, even
those located in the same production area.
CellCom 10 may be used stand-alone or connected with party-line and/or digital
matrix intercom systems. The base station holds connections for several wired
interfaces, including party lines, 4-wire sources, a program audio source, and a
stage announce output device. When wired to the base station, these devices
A CellCom 10 system
consists of three basic
elements: the base station,
wireless beltpack, and
antenna.
With the basic three
elements you can design a
digital wireless system for
your specific requirements.

communicate seamlessly with the wireless beltpacks. Party-line beltpacks and
4-wire matrix stations and panels can key directly to wireless beltpack by name.
CELLCOM 10 FEATURES
Features of CellCom 10 include:
• Base station in one rack unit (1 RU).
• Up to ten wireless beltpacks.
• Point-to-point and small group wireless communications.
• Up to six communication routes per beltpack.
• Party-line beltpacks, 4-wire devices, program audio source, and stage
announce output seamlessly included in communication system.
• Up to ten remote transceiver/antennas create custom coverage zones.
• Transceiver/antennas can be located up to 1,000 meters (3,200 feet) over
CAT-5 cable from the base station, avoiding expensive RF cable.
• Five-character labels for each beltpack and wired connection.
• Communication groups can be created, customized, and assigned to beltpack
keys.
• License-free operation in the1.9 GHz band—above television and other
wireless communications.
• Frequency-hopping DECT technology automatically finds clear spectrum.
• Base functions like a digital matrix; each beltpack has a “virtual port” timeslot.
• Secure system—beltpacks are registered to a particular base and can frequency
hop.
• Two bases can connect locally for a 20-beltpack system.
Figure 2: A CellCom 10 Digital Wireless Communication System
The CellCom 10 base
station functions as a
full-duplex digital matrix
switcher and router for voice
communications.
Each antenna can support
communications with up to
five wireless beltpacks
operating within its coverage
zone.

CELLCOM 10 WIRELESS COMMUNICATION SYSTEM 1-3
A CELLCOM 10 COMMUNICATION SYSTEM
A CellCom 10 system consists of three basic elements:
• The wireless beltpacks.
• The base station that routes communication to and from wireless beltpacks
and other audio devices.
• The transceiver/antennas that provide custom coverage zones in which four to
five beltpacks can operate. Beltpacks can roam freely between coverage zones.
CellCom operates using a cellular network of antennas located around a working
environment. The antennas connect directly to the CellCom base station with
CAT-5 cable. Each antenna provides an area or “cell” in which four to five
full-duplex beltpacks can operate. Figure 2 above shows an example
configuration.
Beltpacks can roam among and between cells without dropping off because each
antenna continually signals a beltpack as to the strongest available signal. When
the signal from an antenna starts to diminish due to the distance from a beltpack,
the beltpack automatically “hands off” its signal to the nearest antenna, ensuring
smooth transfer.

Using an antenna splitter allows you to connect up to five antennas to one
base-station antenna port. A single CellCom base station supports ten beltpacks
and up to ten antennas, giving you a great deal of flexibility in placing beltpacks
where they are needed most, and for providing wireless reliability. For added
coverage, you can connect a second CellCom 10 base station to the first, creating
a 20-beltpack system. Figure 3 illustrates how a CellCom 10 system can be set up
to operate in a single studio or in a large-scale permanent broadcast facility.
Note: Each antenna is designed to handle five beltpacks simultaneously in good
conditions. However, if interference or propagation problems occur in an area, to
ensure proper operation and reliability, it may be more practical to install four
beltpacks for each antenna.
For zones in which you are likely to need coverage for five or more beltpacks
simultaneously, it is recommended that you install a second antenna. Similarly,
for good coverage for nine or more beltpacks simultaneously, a third antenna
may be required.
Note for North American customers: The limited bandwidth of 1.92–1.93 GHz
allows one RF cell to accomodate a maximum of five transceiver antennas. A base
station can therefore furnish two separate cells with a total of ten antennas.

CELLCOM 10 WIRELESS COMMUNICATION SYSTEM 2-1
