Basic Localisation

Localisation via Base Station

In contrast to exact location with inductive localisation transmitters, no additional hardware is required for basic localisation.
Basic localisation is a rough localisation of the current location of a handset, based on the base station number to which the handset is connected.


In case of an alarm of the handset, the base station number is transmitted to the DECT security server. This information is, of course, not as accurate as the room- and floor-accurate detailed localisation with IOS devices, but gives a very good estimate of the part of a building or system in which a search process should be started.
 
The accuracy of the basic localisation depends on various factors:

The handset is normally connected to the base station with the best radio reception conditions. In many cases, this is the closest base station, but attenuation by walls and ceilings within a building can lead to variations.
In the open field, the range of a base station is up to 200m, but in buildings the range can be drastically shorter, allowing a higher accuracy of localisation.
 
Rough localisation via the DECT base station can be combined with accurate localisation using inductive localisation transmitters so that a location can be divided into critical and non-critical areas.
The base station positions can also be linked to the building floor plans in the DECT Security Server with the base station location in order to obtain a quick overview in the event of an alarm.
