Abstract: A technique corrects errors in locations of a vehicle in response to current locations falling within one or more geofences that define regions where the vehicle is unlikely to be traveling. In response to a current location of the vehicle falling within the bounds of such a geofence, the technique adjusts the current location by a defined offset. The offset has the effect of modifying the current location toward a more likely, actual location of the vehicle.

Abstract: A Bluetooth plus radio frequency identification (RFID) beacon for use vehicle fleet management and geofencing system, wherein the beacon comprises a housing, and a circuit board disposed within the housing. The circuit board comprises a Bluetooth communication circuitry portion containing a unique media access control (MAC) address, and an RFID circuitry portion integrated with the Bluetooth communication circuitry portion such that the RFID circuitry portion is associated with the Bluetooth circuitry MAC address whereby the Bluetooth beacon can be identified, via the MAC address, by an RFID reader communicating with the RFID circuitry portion using the MAC address of the Bluetooth communication circuitry portion.

Abstract: Methods are disclosed for scheduling resources in a wireless backhaul network comprising a plurality of N Hubs, each Hub serving a plurality of K Remote Backhaul Modules (RBMs), using a coordinated power zone assignment across the backhaul network. For each Hub, a one-to-one power zone assignment, of each of the K RBM to one of the K power zones, is computed by maximizing a selected network utility across the backhaul network. Coordinated power zone assignment according to preferred embodiments based on the auction approach offers a close-to-global-optimal solution. Coordinated scheduling based on first assigning RBMs to hubs heuristically, and then optimally scheduling RBMs within each hub also offers significant performance improvement as compared to non-coordinated systems. Preferred embodiments offer a significant performance improvement as compared to conventional systems.

Abstract: Methods and apparatus are provided for managing interference in a wireless backhaul network comprising a plurality of hubs, each hub serving a plurality of remote backhaul modules (RBM), using power control with a one-power-zone (OPZ) constraint. Each hub uses a transmit frame structure comprising a plurality of zones, each RBM is scheduled on a different zone, and the same power level is maintained across all zones within a transmit frame. Under the OPZ constraint, and for scheduling policies under which the number of zones assigned to each RBM is fixed, the power and scheduling sub-problems are decoupled. This enables power control independent of scheduling, using methods having lower computational complexity. Methods are disclosed comprising iterative function evaluation or Newton's method approaches based on a weighted sum-rate maximization across the network, which can be implemented in a distributed fashion. Some of the methods can be implemented asynchronously at each hub.

Abstract: A med and apparatus is provided that allows M transceivers to transmit/receive using M2N distinct beams using passive beam steering. This provides for the use of arbitrary narrow beams with a number of transceivers that is a fraction of the number of beams but ensures 360° coverage. In other words it permits significant improvements in the link budget with a minimal rise in the cost of the BS. The apparatus includes M distribution switches applied 2N passive beam forming networks each coupled to M antennas. The method and apparatus ate compatible with TDMA in the downlink and in the uplink.
