7.4 Beltpack support capacities for FS II Transceivers
FreeSpeak II for Eclipse HX (FS II used with a Matrix) will support up to a maximum 50 beltpacks
per E-Que-HX card. As the Matrix can support up to 4 E-Que-HX cards, a maximum of 200
beltpacks can be used, according to conditions.
Each FSII 1.9 GHz transceiver can support five beltpacks within one coverage zone. Each FSII
2.4 GHz transceiver can support four beltpacks within one coverage zone. This reduction is due to
system losses in the 2.4 GHz frequency range. With the omnidirectional transceivers, the
coverage pattern is circular, with a maximum range of up to 500 metres. An average range will be
50 – 150 metres from the transceiver.
When designing the system, determine how many beltpack users will be in or passing through a
given coverage zone. If it will be five or fewer users, then place one transceiver in the center of that
area. If it is between 6 and 10 users, place two transceiver next to each other, both with a direct
connection to the FS II Matrix or splitter. In larger systems – approaching 20 beltpacks – it is
advisable to allow one transceiver for every 2 to 4 users to ensure smooth handoffs between
transceivers. It is good practice to have each beltpack “seeing” two or more transceivers, so a
minimum of two transceivers in any system is to be considered.
If an extra beltpack user goes into a coverage zone with only one transceiver, and that user is out
of range from another transceiver, it will lose connection with the system. This is because the
transceiver has a maximum capacity of up to five beltpacks at a time. If one of the existing users in
that coverage area turns off a beltpack or leaves the area, then the extra beltpack will find an open
slot and will be reconnected with the system.
The proprietary technology within FS II permits the beltpack user to go between coverage zones
created by different transceivers connected to the Matrix, and for the system to hand over the
communication between beltpack and Matrix from one transceiver to the next one. Thus, a larger,
customizable communications area may be designed.
For more information on the coverage range of the FS II-TA, see 3.5 Determining coverage
areas on page 79.
Note: For most working systems, Clear-Com recommends a ratio of 2-4 users per transceiver due to
system losses.
7.5 Placing the transceivers and splitters
Note: You can only use the FS II splitter with FS II transceivers that connect to an E-Que card. You
cannot use the splitter with the FreeSpeak II IP Transceiver.
The next step is to begin placing transceivers and splitters to provide the necessary coverage
areas for all of the beltpacks. The first placements of transceivers and splitters will be experimental
and temporary. After placing the transceivers, walk through the coverage areas to check for gaps
and then re-locate the transceivers accordingly.
