Disclosed herein are techniques for determining a location of an antenna supporting structure. Crowdsourced data associated with antennas that are installed on a same antenna supporting structure but are used for different air interface types and/or data from aerial images can be used, alone or in combination, to more accurately and more efficiently determine the location of the antenna supporting structure and therefore the locations of the antennas on the antenna supporting structure.

Disclosed is a method for determining beam search space by a user equipment (UE), including determining a geo-location of a base station and a geo-location of the UE at a current time instance, determining a relative angle of reception from the base station based on the geo-location of the base station and the geo-location of the UE at the current time instance, determining a beam search space comprising a plurality of beams, for measurement, centered at the relative angle of reception, and determining an optimal beam from within the beam search space based on the measurement of the plurality of beams in the beam search space.

A method of determining locations of access points in a venue, one or more electronic devices configured to receive radio signals from the access points, the method comprises: generating and storing, at a server in communication with the one or more electronic devices, a database comprising information received from the one or more electronic devices, the information comprising: values associated with a radio signal characteristic of the radio signals at locations of RF scan capture by the one or more electronic devices and access point identifiers representing access points corresponding to the values, the locations of RF scan capture being unknown at a time of RF scan capture; assigning correlation values to quantify similarity between the values for pairs of the access point identifiers; mapping the correlation values to correlation ranges based on known locations of at least two of the access points; determining the locations of the access points based on the correlation ranges and the known locations.

A technique is provided for localizing a plurality of wireless transmitters. The technique includes retrieving Received Signal Strength Indicator (RSSI) values measured by one or more sensors, corresponding to the plurality of wireless transmitters distributed in a region in which the sensors are located. The technique further comprises generating, a plurality of clusters based on the retrieved RSSI values. The technique further comprises generating a binary image based on the generated clusters. The binary image comprises one or more white regions and one or more black regions. The technique further comprises localizing position of each of the plurality of wireless transmitters, based on a determination of contours of the one or more white regions present in the binary image.

Disclosed is a method performed by a position calculation node (160) in a wireless communication network (100). The node (160) is arranged for improving accuracy when determining positions in the wireless communication network. The method comprises obtaining a signal transport time value for each of a plurality of different geographical UE positions (UE1, UE2, UE3), wherein the respective signal transport time value relates to the time it takes for a radio signal to travel between a first base station and one of the plurality of UE positions. The method further comprises obtaining a geographical position value for each of the plurality of different geo-graphical UE positions, the position values being independent of the signal transport time values, and determining an actual geographical position for the first base station, based on the obtained signal transport time values, the obtained position values and a predefined geographical position for the first base station.

A method of associating environmental context with wireless access points is disclosed. In some embodiments, a method on a user equipment may comprise determining at least one environmental context associated with a subset of one or more Access Points (APs) visible to the UE at an estimated location of the UE. The at least one environmental context associated with the subset may be determined based on one or more of wireless measurements by the UE, and/or sensor measurements by the UE. Further, at least one AP cluster may be determined by clustering the subset of the one or more APs visible to the UE based on the at least one environmental context and the estimated location. Environmental context for APs may be crowdsourced and stored and provided to a UE as location assistance information to facilitate location determination and other functions.

A method and system of tracking and reporting locations of entity employees, the method for use with at least a first interface device including a display screen, the method comprising the steps of, providing a processor programmed to perform the steps of, storing schedules of entity employees where the schedules indicate scheduled locations of employees during time slots, receiving an indication from a first employee indicating at least a first future time slot, identifying locations of the entity employees during the future time slot, using the schedules of entity employees to generate a location representation indicating the locations of at least a subset of the entity employees during the at least a first future time slot and presenting the location representation via the first interface device.

A method of operating an apparatus for predicting and redistributing a personal mobility vehicle (PM vehicle) demand for shared PM vehicles includes generating demand information for the PM vehicles for a plurality of areas according to time, generating current distribution information for the PM vehicles positioned in the plurality of areas, generating target distribution information based on the demand information and the current distribution information, and redistributing the PM vehicles according to the target distribution information.

Systems and methods are provided to simultaneously determine both angle of arrival (AoA) and angle of departure (AoD) of a signal transmitted between two or more radio frequency (RF)-enabled wireless devices (e.g., such as BLE modules). The disclosed systems and methods may be so implemented in one embodiment to determine AoD even in the case where the transmitting wireless device is at the same time operating in a departure (or AoD) transmitting mode by transmitting a RF signal from multiple antenna elements of at least one switched antenna array using a given switching pattern or sequence implemented by an array switch.

Described herein are technologies relating to assigning wireless beacons to positions within a building, wherein the wireless beacons are included in an indoor positioning system. A computer-implemented floorplan representation is generated, wherein the representation includes a layout of the building and materials of structures of the building. Coverages of wireless beacons are simulated, and multiple objectives are balanced to identify a number of wireless beacons to deploy in the building and positions in the building where the wireless beacons are to be deployed.
