Abstract: A method of geolocating comprises: receiving wirelessly, at an asset located on the Earth's surface and from at least two airborne aircraft, ADS-B signals, respectively; interpolating, using a Bayes filter, at least some state information of the at least two airborne aircraft based on the ADS-B signals, respectively; determining differences in received signal strength indicator (RSSI) values (RSSI-difference values) of successive aircraft-specific ADS-B signals, respectively; estimating, using a likelihood function, locations of the asset based on the RSSI-difference values, the ADS-B signals and the interpolated state information, respectively, thereby producing a set of estimated locations; and searching amongst the set to find one of the estimated locations that is regarded as being most likely to most accurately describe an actual position of the asset.

Abstract: Provided are apparatuses and methods for control of each of data usage and power consumption of cellular network services. Based on such control, a consumer cost of that data usage is reduced, and a battery life of a device for carrying out data communications is increased.

Abstract: A method, of operating an end node to wirelessly communicate with a central node, includes: receiving wirelessly a current instance of a beacon signal periodically-transmitted from the central node; measuring a received power, PB-RX, of the beacon signal; reading locally-stored values of PB-TX and G representing a presumed transmitted power of the beacon signal and a performance goal of the end node, respectively; determining, for a given channel, a path loss, PL, based on the PB-RX and the PB-TX; and adaptively setting an energy level, EN-TX, of a forthcoming message to be transmitted from the end node by adaptively determining, based on PL and G, at least two of: a level of power, PN-TX; a forward error correction coding rate, c; and a spreading factor, SF; and a modulation format, M.
