Abstract: Techniques for ranging for a mobile device with one or more electronic devices using communication circuitry implementing a wireless protocol can include storing a schedule for a plurality of communication sessions. The technique can include broadcasting the advertising packets during a selected number of available time slots of a second time period, the advertising packets including information about the schedule for the plurality of communication sessions. After broadcasting an advertising packet during a selected time slot, the technique can include entering a reduced power state for the communication circuitry until a subsequent advertising packet is sent or a subsequent first time period for communicating the ranging packets as specified by the schedule. The technique can include exiting the reduced power state for the communication circuitry prior to the subsequent first time period. The technique can include transmitting a ranging packet via the wireless protocol according to the schedule.

Abstract: An electronic device may receive a first signal from a first transmitting device at a first time. The electronic device may receive a second signal from a second transmitting device at a second time. The electronic device may access location information for the first transmitting device and the second transmitting device. The electronic device may receive a message from a second electronic device having a known distance relationship to the first transmitting device and the second transmitting device, wherein the second electronic device is configured to receive the first signal, the second signal, and the message including timing information of the signals. The electronic device may determine the position of the electronic device using the location information and the timing information, wherein the position is dependent on the known distance relationship.
