Taking measurements

Measuring the wireless range of the planned base stations
Take two different measurements.
1 Measure the connection quality between the measuring handset and measuring base station
in their wireless cells to ensure that sufficient voice quality is guaranteed at every position
in the required coverage area. Taking the same measurement for the neighbouring station
produces the overlap zone required for a handover.
2 Measure the strength of the signal from the measuring base station that you receive at the
planned position of the neighbouring base station to ensure sufficient synchronisation overlap.
Measurement sequence
The sequence in which you measure the wireless range of the planned base stations depends on
the size of your DECT network and your assumptions with regard to the existing "problem areas".
As a rule of thumb, first measure the base stations whose positions have the least leeway.
Take the following aspects into consideration:
•
Assumed problem areas
For base stations that are to cover specific problem areas, e.g., a stairwell or entrance area,
there are often few alternative positioning options. In this case, measure these base stations
first because the positioning of all other base stations depends on these initial positions.
•
For large installations
The more base stations you use, the higher the requirements of the synchronisation hierarchy
(
P. 18). In this case, we recommend starting with the base station for which a subsequent
change would mean the greatest effort. This is usually the base station with sync level 1.
Start here and move outwards from sync level to sync level.
•
For small installations
Here it makes sense to start with the base station where the highest call traffic is to be expected,
e.g., base stations in hotspots or other high-traffic areas. Once the coverage of these areas
is ensured by measurement, check the positioning of the other base stations.
