ABSTRACT:
A static but movable device has a short-range wireless transceiver by which it can receive location data items. These items are usable by a location-data processing arrangement of the device to derive an estimate of the current location of the device. If the device is moved to another location, this estimate will cease to be valid. Accordingly, the device is provided with a move detection arrangement for detecting indications that the device may have been moved, these indications being used by a location-validity supervisor to determine whether or not the current location estimate is to be treated as still valid.
