    Abstract: A portable battery-powered communications device is configured to operate in a bidirectional communications mode in which voice and/or data is communicated in a bidirectional manner using a bi-directional communications protocol; and to operate in an emergency beacon mode. When the device is in the emergency beacon mode the device is configured periodically to transmit an emergency positioning message at maximum power using the bi-directional communications protocol, transmission of the emergency positioning message defining a beacon transmit period; optionally, to listen for transmissions using the bi-directional communications protocol in a beacon response period immediately following the beacon transmit period; and to refrain from powering transmit and receive circuitry of the device other than during the beacon transmit period and the beacon response period.

    Abstract: Apparatus (30) comprises a battery power supply, a radio-frequency transceiver, a multi-element antenna, and processor and memory. Software causes the apparatus (30): when in an idle mode, to broadcast positioning service advertisements and to refrain from broadcasting positioning packets, when in a positioning mode to broadcast positioning packets from each of the elements of the antenna (32A-C) such as to allow a mobile device (10) to determine a bearing to the mobile device (10) from the apparatus (30), and to transition from the idle mode to the positioning mode in response to receiving either a) a wake-up command or b) a positioning packet, from another apparatus including a multi-element antenna. The apparatus (30) may comprise a Bluetooth Low Energy transceiver; and software that causes the apparatus (30): to transmit advertisements for positioning services on a first channel; and to broadcast positioning packets on a second channel such as to allow a mobile device (10) to determine a bearing to the mobile device (10) from the apparatus (30), wherein the first and second channel are on different frequencies.

    Abstract: Apparatus comprises one or more processors in communication with one or more memories. The one or memories have stored therein one or more computer programs that include computer code configured such as when executed to cause the processor to: receive data derived from a multi-element antenna direction finding arrangement; process the received data to provide elevation and azimuth vector data; determining whether the elevation data meets a reliability criterion. On a positive determination the elevation and azimuth data is used to calculate a location. On a negative determination, the data is processed to provide one-dimensional azimuth vector data; and the one-dimensional azimuth vector data is used in conjunction with other vector data to calculate a location.
