Each FS II transceiver antenna can support up to five FS II beltpacks within one RF coverage zone.  With the omni-directional antennas, the coverage pattern is omini-directional, with a maximum range 300 meters.  When designing a 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 FS II beltpack 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.

Open

If a sixth FS II 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 FS II 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 FS II 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.
Note: For most working systems, Clear-Com recommends a ratio of 3-4 users per antenna due to system losses.
