9.1.4 Beltpack support capacities for transceiver/antennas
Each transceiver/antenna can support five beltpacks within one coverage zone. With the
omnidirectional antennas, the coverage pattern is circular, with a maximum range of up to 500
metres.
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/antenna in
the center of that area. If it is between 6 and 10 users, place two transceiver/antennas next to
each other, both with a direct connection to the FS II Base station or splitter. In larger systems
– approaching 20 beltpacks – it is wiser to allow one transceiver/antenna for every 3 to 4
users to ensure smooth handoffs between transceiver/antennas. It is good practice to have
each beltpack “seeing” two or more antennas, so a minimum of two antennas in any system is
to be considered.
If a sixth beltpack user goes into a coverage zone with only one transceiver/antenna, and that
user is out of range from another transceiver/antenna, it will lose connection with the system.
This is because the transceiver/antenna has a maximum capacity of 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
sixth 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 transceiver/antennas connected to the Base station, and for the
system to hand over the communication between beltpack and Base station from one
transceiver/antenna 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 4.2.3 Determining
coverage areas.
Note: For most working systems, Clear-Com recommends a ratio of 3-4 users per antenna due to
system losses.
9.1.5 Coverage areas under various conditions
Just as with any other product communicating via radio waves, the effective distance between
the beltpack and the transceiver/antenna (the range) will differ depending on the particular
environment in which it is being used. Radio waves can be attenuated by walls, floors,
ceilings, trees, shrubbery, the human body (such as an audience), and numerous other
