摘要： A method and an apparatus in a first wireless station of a network transmitting to a second wireless station through OFDM signals. The first station includes multiple antennas (113, 115) and a receive and a transmit signal path per antenna. Each receive signal path includes a discrete Fourier transformer (445, 447) and each transmit signal path includes an inverse discrete Fourier transformer. The method includes determining channel estimates (449, 451) for each tone and each receive path while receiving from the second station, determining transmit weights (475) to transmit to the second station, tone-by-tone weighting a signal for transmission to the second station to produce weighted tone sets for each transmit signal path, and transmitting the weighted tone sets (417, 419).

摘要： Described herein are a computer-implemented method of determining a power plan/frequency plan combination assigning transmit frequency channels and transmit powers for a plurality of managed access points (APs) of a wireless network. Also described herein is a carrier medium carrying computer readable code configured to cause one or more processors of a processing system to implement the computer implemented method of determining a power plan/frequency plan combination. The method includes determining candidate power plans for the access points, including determining candidate transmit powers for the access' points, determining a candidate frequency plan corresponding to each of the determined candidate power plans using a frequency plan determining method to determine a set of candidate power plan/frequency plan combinations, and rating each combination of a candidate power plan and candidate frequency plan according to an evaluation criterion, and selecting a preliminary power plan/frequency plan combination based on the rating. One embodiment of the method further includes determining a final power plan for the preliminary frequency plan of the preliminary power plan/frequency plan combination to obtain a final power plan/frequency plan combination.

摘要： 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.
