A CELLCOM COMMUNICATION SYSTEM
A CellCom system consists of three basic elements:
• The wireless beltpacks.
• The basestation 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
basestation with CAT-5 cable. Each antenna provides an area or “cell”
in which four to five full-duplex beltpacks can operate. Figure 1-2 on
page 3 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.
