In addition the system may also be configured to determine first location-related data for the first access point. Determining second location-related data for a second access point of the plurality of access points, the second access point being interior to the first access point within the network includes exchanging ranging data indicative of a first relative distance between the first access point and the second access point, the ranging data based at least in part on ranging message exchange measurements, and communicating the first location-related data from the first access point to the second access point.

An object position-measuring device, a method thereof, and a system thereof are proposed. The object position-measuring device, method thereof, and system thereof are for measuring a position of an object by using a plurality of wireless signals indoors. In the object position-measuring device, method thereof, and system thereof, respective distances from the position-measuring device and first and second wireless communication devices to the object are calculated by using respective travel times of the wireless signals respectively transmitted from the position-measuring device and the first and second wireless communication devices and the wireless signals received after being reflected from the object, whereby the position of the object is measured by using the calculated distances.

Technologies directed to device detection and locationing are described. One method includes establishing a first wireless connection between a first wireless device and a second wireless device on a first channel. The first wireless device sends to the second wireless device a first indication that the first wireless device is to operate in an off-channel mode with a third wireless device at a first location a Fine Timing Measurement (FTM) procedure. The first wireless device performs a first FTM process between the first wireless device and the third wireless device. The first device determines first timing data including a signal round trip time (RRT) associated with the first FTM process and determines a first distance between the first wireless device and the third wireless device based on the first timing data. A second location of the first wireless device is determined using the first distance.

A transceiver system includes one or more groups of transceivers. The locations of the transceivers are initially unknown. During deployment, the location of each transceiver in the group is automatically estimated by the remaining transceivers in the group. Once the locations of the transceivers in the group are estimated, deployment of the transceivers is complete. The transceivers may estimate location attributes of mobile transceivers within a vicinity of the transceivers in the group.

A processor obtains a plurality of instances of access point observation information. Each instance of access point observation information comprises (a) radio observation information corresponding to observation of one or more access points by a respective mobile device and (b) location information comprising an indication of a location of the respective mobile device when the respective mobile device observed the one or more access points. For one or more instances of access point observation information, based at least on the location information of the instance and a digital map that is accessible to the at least one processor, the process identifies a respective (TME) of the digital map that represents a portion of a traversable network where the mobile device was located when the mobile device observed the one or more access points; and associates at least a portion of the radio observation information with the respective TME.

Techniques are described herein for developing a fingerprint map that may be used for 3D indoor localization. In one example, a network server may leverage a building footprint from an open source database with signal measurements taken by probing user devices from signal sources such as access point (AP) devices. The network server may use the signal measurements to remotely calculate corresponding 3D positions of the AP devices in a particular building. Further, the network server may use the building footprint and the calculated 3D positions of the AP devices as references for developing the fingerprint map for 3D indoor localization.
