Base Station Signal Strength
The diagram below indicates the basic measures for coverage between a base station and a DECT phone.
|
Signal
|
Description
|
|---|---|
|
-40dB
|
Strong signal typically seen when a phone is close to the base station.
|
|
-62dB
|
Minimum signal strength at which a base station will accept a phone wanting to handover from another base station.
|
|
-68dB
|
Signal strength below which the phone will begin looking for a base station to which it can handover.
|
|
-75dB
|
At this signal strength, the increased error rate will become apparent in the speech.
|
|
-90dB
|
At this signal strength calls are likely to disconnect. This is also the limit for one base station to synchronize with another.

Though this section focuses mainly on the measure of signal strength, the DECT signalling employs a number of methods to overcome a poor signal. The other key factor that affects signalling is the error rate. While decreasing signal strength and increasing error rate are usually related, there may be some scenarios where a higher than expected error rate occurs.
