Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular access point (AP). Such implementation includes determining a coordinate location of the EN based on position information for multiple reference points (RPs) and a time of flight (TOF) of an ultrasonic waveform transmitted by each of the RPs.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular mobile access point (AP). Such implementation includes determining such connection based on a relative proximity of an EN to the mobile AP, and a relative value of the connection between an EN and the mobile AP. Accordingly, a relative location of the EN may be determined based on such proximity, and particularly in response to mobility of the AP.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) to be operable with a cellular backhaul and as the receiver of messaging generated by components within the network for the downstream cellular transfer of proximity and other types of information collected by the EN. The EN is configured to collect GPS and WiFi positional information determinative of a location of the EN, and transmit such positional information directly from the EN over an available backhaul so as to enable a determination of a relative location thereof based only on that positional information. In these ways, location and other types of information associated with the EN may become known with increased reliability and certainty in the face of obstacles such as structural barriers and distance that ordinarily limit BLE performance.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and other components within the network. Such initiating is controllable by the network so as to effect a transfer of EN functionality among one or more of the other components. Implementation of the transfer depends on a network controlled timing determining functionality of all network components. Accordingly, the network is enabled to effect the power consumption of those components in an effort to optimize use of their respective power resources.

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 systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular access point (AP). Such implementation includes determining a location of the EN, in which that location is resolved by the EN and defined with respect to exchanges of Constant Tone Extensions (CTEs) between the EN and reference points (RPs).

Doing so includes implementing an end node (EN) as the sole initiator of establishing a connection between a particular EN and a particular access point (AP). Such implementation includes determining such connection based on a relative proximity of an EN to an AP, and a relative value of the connection between an EN and an AP.

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.
