FreeSpeak II for Eclipse | User Guide
Alternatively, use the Site Survey mode on the beltpack (see Doing a site survey to
determine coverage areas on page 89 below). It is often best to begin with one transceiver in
place, and then place additional units to enhance coverage.
Walk through all of the areas where beltpack users will typically be moving, and note any areas
of weak signal, dropout, or disconnection from the system. Pay special attention to the overlap
areas between transceiver coverage zones, making sure sufficient signal strength is there from
each of the transceivers to make a clean handoff between them for the beltpack.
7.7 Coverage areas under various conditions
Just as with any other product communicating with radio waves, the effective distance between
the beltpack and the transceiver (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 objects. They can be
reflected and/or stopped by metallic objects such as structural beams, safety doors, lighting
equipment and truss, bodies of water, and so on.
Under ideal conditions, the maximum range between an FS II beltpack and a transceiver is 500
metres. Typical distances are between approximately 50 metres (about 160 feet) and 150
metres (about 485 feet), depending on the particular environment.
As the transceiver requirements for a particular installation are being determined, keep in mind
both the number of beltpack users who will be working in a particular area (based on the 10
beltpack capacity of each transceiver), and the layout and potential RF attenuating and
reflecting items in the location. Be conservative in distance estimates to make sure that enough
transceivers are included to provide the necessary coverage for the installation. Remember that
additional transceivers may be added to a Matrix.
7.8 FS II Transceiver setup rules and tips
Keep the following general rules and tips in mind:
l
Keep transceivers high (typically, though lower placements away from interfering objects
can at times be beneficial) and line-of-sight.
l
Keep them away from larger metallic objects and surfaces, and from lighting truss.
l
Transceiver coverage is circular so put the transceivers in the center of the area in which
coverage is required.
l
When overlapping the coverage zones of transceivers to create larger continuous
coverage areas, test the in-between areas with a beltpack for potential areas of low RF
signal; adjust the positioning of the transceivers as needed.
