25
positions located on it.
-
Position the transmitter at the proposed Receiver location.
-
Take the RP250GD/RP250GDS to the first proposed transmitter
location.
-
View the transmitter's serial number on the RP250GD/RP250GDS
display.
-
Check the signal strength is greater than 6 chevrons.
-
If the strength is good, mark the survey map with a tick.
-
Continue checking, ticking transmitters when the signal is good.
-
Where the strength is not good, a repeater may be needed.
-
Find an appropriate location for a repeater, both in terms of signal
transmission and daily operation.
-
Move the survey transmitter to the proposed repeater location.
-
Check
the
remaining
transmitter
locations
with
the
RP250GD/RP250GDS.
-
Mark the location of the repeater and tick off transmitter locations
when surveyed.
At the end of the survey you should have sufficient information to update the
plan. There may be an opportunity to rationalise the plan (and perhaps reduce
the number of repeaters) by possibly relocating repeaters. If this is the case the
survey must be repeated to assure performance.
What can you expect in terms of range?
Our experience indicates communication across two floors (wood or
reinforced concrete
–
and vertically inline separated) will be reliable.
On the same floor expect more than 100m if simple prefabricated walling is
used, more if the floor is open, and considerably less if steel or panelling of
mesh lined chambers is present.
Expect 500m for a repeater located in a window which is revealed to another
repeater in a similar location.
Always configure the repeater to pass the transmitter signal of those required
and inhibit those not required. This reduces on-air activity leading to best
system reliability.
