Abstract: Determining the location of a radio tag or client station of a wireless network, and the location of coverage holes by receiving from a plurality of wireless stations of the wireless network path loss information of the path loss of one or more location frames received at the respective wireless stations. The location frames transmitted by the radio tag or client station having a pre-defined frame structure. The radio tags and client stations use a common infrastructure for transmitting a location frame configured for radiolocation by path loss measurement. The common infrastructure includes a pre defined protocol common for both radio tags and client stations for transmitting information for reception by the plurality of stations of the wireless network for radiolocation. The pre-defined protocol includes using the location frame having the predefined frame structure.

Abstract: A method (Figure 1), an apparatus, and code in a carrier medium to operate in a first access point (101) of a wireless network in communication with at least one associated client station (105). The method includes wirelessly broadcasting a management frame including an indication that the first access point will stop being active, such that each associated client station can wirelessly roam to a second access point prior to the first access point ceasing being active. One embodiment further includes reducing the transmit power of wireless communication used to wirelessly transmit information to the associated client stations, such that each associated client station can eventually wirelessly roam to the second access point.

Abstract translation: 在与至少一个相关联的客户站（105）通信的无线网络的第一接入点（101）中操作的载波介质中的方法（图1），装置和代码。 该方法包括无线广播包括第一接入点将停止活动的指示的管理帧，使得每个相关联的客户端站可以在第一接入点停止活动之前无线地漫游到第二接入点。 一个实施例还包括减少用于无线地向相关联的客户站发送信息的无线通信的发送功率，使得每个相关联的客户端站最终可以无线漫游到第二接入点。
