发明名称 Loading Control Methods And Apparatus For Wireless Access Points Of Wireless Local Area Networks In Support Of Legacy Terminals
摘要 Methods and apparatus for use in controlling the loading of wireless access points (APs) in a wireless local area network (WLAN) in support of legacy terminals are disclosed. The WLAN has at least a first AP and a second wireless AP adjacent the first wireless AP. An indication which indicates whether a loading of the second wireless AP is greater than a predetermined threshold is identified. When the indication indicates thai the loading is greater than the predetermined threshold, a first nominal radio frequency (RF) transmission power of the first wireless AP is increased in order to increase a first RF coverage area of the first wireless AP. A second nominal RF transmission power of the second wireless AP is correspondingly reduced in order to reduce a second RF coverage area of the second wireless AP. In response, some of the mobile communication devices initially operating with the second wireless AP are switched to operate with the first wireless AP in order to reduce the loading of the second wireless AP. The techniques may be embodied in a centralized approach where transmission control equipment of the WLAN controls each wireless APs in this manner, or alternatively in a distributed non-centralized approach where each wireless AP acts independently and autonomously in the same or similar manner. Preferably, the techniques do not require the functional requirements of mobile devices to modified and therefore are suitable for use with existing legacy devices.
