Abstract: A radio system is provided which comprises a radio receiver and a processing system, wherein the radio receiver is configured to detect radio signals transmitted from a radio transmitter on a plurality of frequency channels, and to measure respective signal strengths of the radio signals for each of the plurality of frequency channels. The processing system is configured to evaluate a measure of statistical dispersion of the respective signal strengths over the plurality of frequency channels, and to use the measure of statistical dispersion to determine information relating to a proximity of the radio transmitter to the radio receiver.

Abstract: A telecommunications apparatus is provided which comprises a processing system, a cellular-network radio transceiver, a first radio module and a smart card. The smart card comprises a microcontroller, an electrical interface and a second radio module. The cellular-network radio transceiver and the first radio module are connected to the processing system by one or more electrical connections. The smart card is coupled to the cellular-network radio transceiver through the electrical interface and the processing system is arranged to use a radio communication link between the first radio module and the second radio module to communicate data with the microcontroller of the smart card. The smart card is configured to interrupt the processing system by sending data over the radio communication link.

Abstract: A method and system for acquiring information related to a transponder (RFID tag 40) read by a mobile telephone 60 comprising a RFID reader 80, and an identification and authentication module (SIM card 90). When the RFID reader has read the data from the RFID tag 40, the identifier and the content data is processed and transmitted to a local network for further processing and delivery of supplementary information linked to the RFID tag 40. The SIM card comprises a WLAN transmitter, and transmitting of the identifier is via the WLAN.

Abstract: The invention relates to a method for providing mobile communication terminal location data. In the method, radio signal is received from a beacon in a wireless local area network. Next, beacon identification data that identifies the beacon is derived, based on the received radio signal. The identification data is transmitted to a server. Beacon location data is then provided by and received from the server. Mobile communication terminal location data, particularly presence data that indicates that the mobile communication terminal is in the vicinity of the beacon, is derived from the beacon location data. Upon such detected presence, an additional application process is advantageously executed. The method is executed by a processing device in a subscriber identity module that is included in the mobile communication terminal, thus achieving hidden operation and portability. The invention also relates to a subscriber identity module and a system operating in accordance with the method.
