Abstract: The present disclosure relates to a short-range communication device (10, 10?, 5 10?) for a personal protective equipment or a personal protective device (200, 210, 220, 230) comprising a transmission unit (20, 20?, 20?) for wirelessly transmitting a voice signal of a user (100, 110, 120, 130, 140, 150, 160) to a receiving unit (40,40?, 40?) over a predetermined distance such that a communication channel is established between the transmission unit (20, 20?, 20?) and the receiving unit (40, 40?, 40?) so that a user (100, 10 110, 120, 130, 140, 150, 160) can hear the voice signal. The present disclosure further relates to a short-range communication system comprising at least two short-range communication devices (10, 10?, 10?) according to the present disclosure and to a method of establishing a short-range communication between such devices (10, 10?, 10?).

Abstract: A mobile station (105, 200) operable in a wireless communication system (100), the mobile station including means (218, 202 of 105) for reporting to a location server (104) of the system a current location of the mobile station and a controller (201 of 105) for controlling the means for reporting to report to the location server a current location of a second mobile station (107) detected to be near to the mobile station. A wireless communication system (100) in which the mobile station is operable and a method (500) operable in the system are also described.

Abstract: A communication system (100) comprises a plurality of mobile stations (118, 124) each operable to communicate with other communication stations by a wireless link of a first kind, at least one location indicator (116) operable to detect by a wireless link of a second kind a location of at least one (118) of the mobile stations when the at least one mobile station is within a communication range of the location indicator, at least one proxy location server (110) operably coupled to at least one associated location indicator (116), and a location server (108) operable to communicate with the at least one proxy location server to receive a notification of the location of the at least one mobile station (118) when detected to be within communication range of the associated location indicator (116).
