1. An emergency service warning system, arranged to warn a user of approach of emergency services, comprising:
- at least one movable emergency service transmitter and at least one stationary base station, wherein the emergency service transmitter and the at least one stationary base station are arranged to communicate by utilizing encoded digital uplink signals and respective downlink signals; and
at least one user receiver which is arranged to detect encoded digital uplink signals transmitted by the emergency service transmitter to the base station, without deciphering a possible content of the encoded digital uplink signals, and to deliver a warning signal upon detection of an encoded digital uplink signal;
wherein the user receiver is arranged to search for the encoded digital uplink signals transmitted by an emergency service transmitter to the base station utilizing information concerning the base station.
