    摘要: Disclosed embodiments include a method performed by a network access point, such as a short-range wireless communications switch or Bluetooth base station unit, to provide a neighbor list for neighboring short-range wireless communications switches or network access points in a communications network. The method includes, at the short-range wireless switch, sending at least one signal to neighboring wireless devices, wherein sending the signal is done without assistance of a mobile unit or a system controller for the communications network. The method further includes receiving a response signal from at least one neighboring short-range wireless switch, and identifying the one neighboring short-range wireless switch based on the received response signal. Additionally, the method includes providing a neighbor list that identifies the one neighboring short-range wireless switch. Numerous alternative embodiments are also described.

    摘要: A navigation method and system suitable for highly accurate all-weather navigation of vehicles such as ships and aircraft. An initial position of the vehicle relative to a plurality of known points each located at predetermined geographic positions is first determined. The distance or range of the initial position from each of the plurality of known points is determined and when the vehicle moves to a second and unknown position, the difference between the propagation time of electromagnetic wave energy transmitted from each of the plurality of known points at the initial and second positions is determined to thereby determine an incremental change in the distance to the second position from each of the plurality of known points. The distance of the initial position and the incremental change in distance from each of the plurality of points are algebraically summed to thereby determine the distance of the second position from each of the plurality of known points, and the second position is determined from the determined distances of the second position from each of the plurality of known points. The invention is compatible with existing navigation systems such as LORAN or other systems which periodically transmit wave energy at regular intervals.

    摘要: In a network, a method is disclosed for wirelessly exchanging communications with at least one mobile unit. The network includes first and second base stations units coupled to the network, and may include a system controller. The method includes: receiving a communication signal from the second base station unit, wherein the first and second base station units are configured to employ a wireless communications protocol, and wherein the wireless communications protocol does not provide for handoff of communications links between base station units; at the first base station unit, determining if the second base station unit has been synchronized based on the communication signal; at the first base station unit, if the second base station unit is synchronized, then synchronizing an internal clock based on the synchronized second base station, wherein the synchronizing is performed without assistance from a system controller.
