Clear-Com FreeSpeak Beltpack - Manual (Page 71)

Clear-Com Communication Systems
Eclipse Wireless Communication System 5 - 3
Transceiver/Antenna Splitter
Number of Transceiver/Antennas
Supported
10; Note: In the USA, until FCC opens
the
allowed bandwidth, any one
area
can only have 5 antennas.
Number of Splitters Per Base 2
Connection Between Base
and Splitter
4-pair CAT5 cable with RJ-45
Connection Between Splitter and
Transceiver/Antennas
4-pair CAT5 cable with RJ-45
Powering of Splitter Locally powered via external power
supply
Transmission Method
Method of RF Operation DECT standard, using two DECT bands
per
beltpack for wider frequency response
Modulation QPSK
Frequencies of Operation 1.92 – 1.93 GHz
RF Output 250 mW burst, average level 2 - 4 mW
Theory of Operation
Dynamic allocation of frequencies and handoff of beltpacks among the
transceiver/antennas up to their individual limit of 5 connected beltpacks at a
time; each beltpack is assigned a “virtual port” within the Eclipse base.
