System and method of determining the location of an occupied physical space

System for determining the location of one or more occupied or unoccupied physical spaces, the system comprising:

• one or more charging devices configured to be arranged at the one or more physical spaces, each of the charging devices comprising a charging unit configured for wireless power transfer to a mobile telecommunication device when the mobile telecommunication device is coupled to the charging unit;
• one or more localisation units associated with each of the charging devices, wherein each of the localisation unit is configured to broadcast an information signal comprising identifying information of the localisation unit to the mobile telecommunication device;
• a controller configured to determine the location of an occupied physical space upon detection of the coupling between the mobile telecommunication device and the charging device, wherein the location is determined based on the broadcast signal received by the mobile telecommunication device, wherein the charging device is configured to generate a trigger signal when a coupling between the charging device and a mobile telecommunication device is detected and/or when the charging device starts charging the mobile telecommunication device, and wherein the localisation unit is configured to start broadcasting the information signal only if the trigger signal is generated.
