摘要： A device whose location is to be determined (target device) generates a plurality of frames (messages) and time of departure (TOD) timestamp information indicating when the target device transmits the plurality of frames in a sequence or burst. The target device transmits the plurality of frames and the TOD information, wherein the plurality of frames are transmitted such that at least two of the frames are on different radio frequency (RF) channels. Within a sequence or burst (or across multiple sequences or bursts), multiple widely spaced transmissions on the same channel are included to allow for estimation of the crystal frequency offset of the transmitting device. The TOD information included in the transmitted packets allows devices that receive the packets not to change their channels of operation solely for the purpose of receiving packets from the device to be located.

摘要： In one embodiment, wireless access point management is optimized. The data bandwidth and/or processing requirements for data indicating operation of the access point is baselined. For example, air quality or interference measurements are made at the access point on a regular basis. The interference measurements over one or more periods, such as one period of 24 hours, provide a baseline. Rather than transmitting and processing the subsequent measurements that are normal or within the baseline, a lack of information or data requiring less bandwidth than the measurements communicates to a controller or server that the measurements are normal or within the baseline.
