Abstract (en)
[origin: WO9612264A2] Known is a wireless object locating system (1) in which vehicles (15) can be located and followed with great position accuracy. The known system (1) is a combined GPS and cellular mobile radio system. Such a system (1) is complicated and expensive, and furthermore alarm calls are charged. An inexpensive and simple wireless object locating system (1) is proposed only using the infrastructure of a micro-cellular telephony system (1) or a cordless telephony system (1). By applying an emergency call service in such a system alarm messages (40) can be transferred to a central alarm station (16) without being charged. Preferably, a DECT system (1) is applied, the DECT Standard providing by-passing of emergency call messages (40) in private radio base stations (2, 3, 4, 5, 6) without normal call validation.
