摘要： Methods and devices are described for merging maps. In one potential embodiment a method may comprise receiving an indication of at least one plurality of geographically proximate points, where each of the at least one plurality of geographically proximate points are determined by at least one access point in communication with one or more mobile devices. A first and second map may then be received, where the first map and the second map each cover a first area such that the first area is in both the first map and the second map. The first map and the second map may then be merged by matching a mapping of a first portion of an indication of the at least one plurality of geographically proximate points on the first map and a second portion of an indication of an at least one plurality of geographically proximate points on the second map.

摘要： Techniques are provided for utilizing one or more mobile devices to estimate distances between wireless access points (APs). Embodiments can, for example, enable mobile devices, wireless APs, and/or other systems to estimate a distance between two wireless APs using Round-Trip Time (RTT) measurements obtained by one or more mobile devices. The RTT measurements can be utilized based on whether one or more related Received Signal Strength Indication (RSSI) measurements exceed a threshold value. Embodiments can also utilize crowdsourcing to obtain distance estimation data (e.g., distance estimates, RTT and/or RSSI measurements, etc.) from one or more mobile devices and/or propagate a determined distance, based on the distance estimation data, to multiple devices.
