Transceiver placement
Each FreeSpeak II Base has capacity for 25 beltpacks and up to 10 transceivers (using two splitters). You need to place transceivers to create a custom coverage zone to suit your requirements, taking into account the physical environment and beltpack user needs.
- Example set up.
- Consider both capacity and coverage. How many beltpack users are there and what are their movements? Ensure that you have enough capacity where users congregate, as well as allowing for coverage area.
- What are the individual characteristics of your site? Radio waves can be reflected by metallic objects, and reduced by some objects, including the human body (for instance, a large audience can affect transmission).
- What conduit (cabling) is already available on site? Are there power points? Splitters must be powered locally, and Clear-Com recommends powering transceivers locally.
- As a general rule, transceivers should be placed 8 – 10 feet high (2.5 – 3 meters high).
- When co-locating transceivers for extra beltpack capacity in one area, do not put the devices too close to each other. They should be placed between 3 and 20 feet (1 - 7 meters) apart .
- FS II transceivers can be placed at any orientation in confined areas. However, in larger venues or outdoors, aim the transceiver to the front of the required coverage area.
Clear-com recommends a conservative approach to transceiver capacity, to ensure coverage and allow for system losses.
1.9 GHz : 3 - 4 beltpacks per transceiver
2.4 GHz: 2 - 3 beltpacks per transceiver.
Transceivers provide circular (omnidirectional) coverage.
In ideal conditions, a transceiver range can go up to 500 meters (1640 feet). However, an average range, taking into account objects and conditions that impede radio waves, is between 50 - 150 meters (164 - 490 feet).
The Base Station can power 1 transceiver to a distance of 100 meters (328 feet). More than one transceiver and/or greater distances will need direct power supplied to the transceiver.

Connecting devices over Fiber will increase potential distances from Base to transceiver. See Install Fiber Module. |

It is advisable to place transceivers temporarily until coverage has been tested. Once transceivers have been temporarily placed, test the coverage zone by putting a beltpack in Site Survey mode and walking through the area monitoring signal strength.
