consistently 2% or more, there may be interference from external wireless equipment. In this case,
the results below may happen regardless of the radio signal strength level.
If the error rate is consistently 2% or more without interference from external wireless equipment,
it is likely that metallic materials in the surrounding structures are causing interference. In this case,
move the CS or increase the number of CSs in the area.
Error Rate
Result
Approx. 2%
May receive noise
Approx. 10%
May fail to make/receive calls
The above is a rough standard, and may vary depending on the environment.
•
When deciding where to install the CS, priority should be given to an error rate rather than a radio
signal strength level.
•
After installing the CS according to the results of the survey, confirm that calls can be made and
received, and conversations can be heard clearly.
a.
Move to the CS until the radio signal strength level becomes "17" or "18".
b.
Move away from the CS and identify the CS coverage area within which the radio signal strength
level is greater than "8". Draw the area on the map.
c.
Move away from the CS and identify the CS coverage area within which the radio signal strength
level is greater than "3". Draw the area on the map.
