Abstract: The present disclosure proposes a handover management method and a base station having a smart antenna using the same method. A transceiver of the base station transmits and receives wireless data. An interface controller of the base station transmits a source beam-forming information and receives a target beam-forming information. A processing circuit of the base station is coupled to the transceiver circuit and the interface controller and is configured for transmitting the source beam-forming information when switching to a setting of the smart antenna corresponding to the source beam-forming information and receiving the target beam-forming information using the interface controller, recording the source beam-forming information and the target beam-forming information as a beam-forming pair to a history of a handover when performing the handover, grouping the beam-forming pair in the history into beam-forming pair groups, and determining handover parameters for each of the beam-forming pair groups respectively.

Abstract: A method for navigation of a movable platform is provided. The method includes the steps. First, a plurality of reflection devices is placed to mark a range. A coordinate location and a direction of the movable platform are received by a positioning system, At least one laser to measure relative positions and distances between the reflection devices and the movable platform are emitted by a laser range finder, respectively. Absolute locations of the reflection devices and the range are calculated by a processor according to the coordinate location and the direction of the movable platform, the relative positions and the distances between the reflection devices and the movable platform. The reflection devices are scanned and tracked by the processor, and the coordinate location and the direction of the movable platform and the absolute locations are calibrated by the processor to control the movable platform to move in the range.
