摘要： Disclosed herein is wireless home LAN system using multiple antennas, and a wireless access point (AP) apparatus in a communication system for providing a plurality of terminals contained in a closed specific area with a wireless access service that includes a plurality of wireless modules arranged in the closed specific area at intervals of a predetermined distance, that are selectively activated, and a control module connected to the wireless modules by wire, for controlling communication performed in the area of the terminals and connection to an external network using the activated wireless modules. The apparatus selectively activates antennas in only a specific area requesting a communication service using a single controller and a plurality of antennas connected to the controller, such that it can solve performance anomalies and inter-cell frequency interference problems. Also, the apparatus controls propagation beams to concentrate on a minimum area, resulting in improved security.

摘要： A handoff method is provided in a communication network including a plurality of fixed nodes attached to a router connected to at least one external network, and at least one mobile node associated with a current fixed node. The method detects movement of a mobile node; prepares a handoff of the mobile node from a current fixed node to potential fixed nodes upon detecting movement of the mobile node; decides whether to handoff to one of the potential fixed nodes as a target fixed node; and performs the handoff from the current fixed node to the target fixed node. The handoff method enables the mobile station to quickly move its association from one access point to another by minimizing a probe delay which is a primary contributor to handoff delay.
