7.1.2 Quick Verification of Area Coverage
The purpose of this test is to check whether the necessary field strength and the
transmission quality is attained throughout the entire radio network.

Step 1
The purpose of this step is to provide the basis for step 2 where you will use a

•
Establish a voice connection between two mobile telephones. If you wish, you
can use an announcement service (for example "speaking clock").
Step 2
This step involves obtaining a rough assessment of the area coverage.
•
With a mobile telephone in measuring mode, move around the area in
question and determine whether an RSSI value > 50 (-60 dBm) and a FRAQ
value > 95% are reached throughout the area.
In the process, the Range Warning feature can be used as an aid for
recognizing the radio area boundaries. A warning tone (range warning) is
