Abstract: In an implementation, an electronic device may obtain a configuration file from a device provider. The configuration file may include settings of a number of communications providers for communicating over a wireless wide area network. A subscriber identification module (SIM) card may include information, such as a communications provider identifier, that is utilized to determine the settings for a modem of the electronic device. Configuring the modem of the electronic device according to the settings may cause the modem to communicate over the wireless wide area network according to specifications of a particular communications provider of the plurality of communications providers.

Abstract: Described is an improved active-beacon/passive-listener time difference of arrival navigation system that relies on the multiple beacons to transmit uncoded acoustic pulses of a same frequency that propagate in the system at a same time for high-speed device tracking. Listening devices may receive multiple encoded radio frequency pulses (RF) prior to a single acoustic pulse, and then resolve which RF pulse corresponds to the acoustic pulse using triangulation techniques.

Abstract: An improved active-beacon/passive-listener time difference of arrival navigation system that relies on the multiple beacons to transmit uncoded acoustic pulses of a same frequency that propagate in the system at a same time for high-speed device tracking. Beacons are scheduled to transmit independent of the location of listening devices in the system. Listening devices may receive multiple encoded radio frequency pulses (RF) prior to a single acoustic pulse, and then resolves which RF pulse corresponds to the acoustic pulse using triangulation techniques.
