Positioning
When considering where to place RP32 Receiver Modules, it is useful to think of them as
“lights” with which you are attempting to cover and entirely fill a space. A rough
guideline of coverage pattern is shown below. This guideline is only a starting point. The
effects of multipath both to and from the RP32 are very beneficial and create additional
paths which “fill in” the coverage area. Although the system will work with only a single
RP32 picking up and communicating with a BP24 beltpack, we recommend that you
position the RP32s such that you have a minimum of 2 actively receiving the BP24 signal
at all times, and preferably a minimum of 3. There is no signal to add, subtract, or
interfere, so the more RP32s that communicate with and receive a BP24 the better.
Think of it as an up to 32-way digital diversity. All RP32s process all of the possible 24
channels of BP24 transmitters at all times. It does not matter which RP32 picks up a
signal or sends a signal. No pairing or other coordination is required. Once power is
applied to an RP32, it will automatically begin sending sync pulses to BP24 transmitters
(whether or not they are present) and they will look to receive a signal from a BP24
transmitter on the correct TDMA time slot.
A note about physical obstacles: Since this system operates in a very high frequency
range, the wavelengths are very short. That means that it is possible for them to “pass
through” porous materials. Although it is not optimum, it is sometimes possible to place
RP32s behind a surface if that surface will still allow the small 6GHz wavelength to pass.
A metallic or glass or stone surface is highly reflective and is beneficial for creating
supporting multipath, but it will not allow signals to pass through.
