Abstract
Methods and apparatus relating to the detection of one or more devices in zones, e.g., non-overlapping areas, are described. Individual device locations are made based on RSSI information. Whether a user is determined to be in a zone or not is determined based on location determinations corresponding to the device. Thresholds used to determine whether a device is to be considered as being within a zone differs depending on whether the device is newly detected in the zone or is already determined to be in the zone. In some embodiments it is easier to be determined to be in a zone than to be determined to have left a zone. A device may be determined to be in two non-overlapping zones at the same time thereby increasing the chance that devices in edge areas will be counted with regard to the number of devices for which resources should be provided.
