The communication means comprise at least a short-range transmission/receiver unit. The signalling method for anti-theft systems of motor vehicles or the like comprises the phases of: detection of the theft of or undesired access into a motor vehicle; sending of an alarm signal towards a remote control unit, by means of a transmission/receiver system operating with mobile phone protocols; checking the connection between the transmission/receiver system and the remote control unit. In case of absence of connection between the transmission/receiver system and the remote control unit, the sending phase comprises the transmission of the alarm signal by means of a short-range transmission/receiver unit.</p> |
