5.5.3 Measuring the Signal Strength

You can measure the error rate and the radio signal strength by moving towards and away from the CS.
Note
•
If the error rate is 2% or more, measure the error rate at the same location at least 5 times. The rate
varies for different regions. For details, refer to the following list. You must disconnect the CS and then
reconnect it to take each measurement.
If the error rate is 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.

If the frame error value continues to increase abnormally (100 per second), the radio signal has been
lost. In this case, re-perform the procedure in "5.5.2 Preparing PSs to Test the Radio Signal
Strength" starting from
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.
