An edge device includes a first antenna array that includes a first portion and one or more second portions. The edge device includes control circuitry that senses a surrounding area of the edge device in a first frequency by use of the first portion of the first antenna array. The control circuitry executes beamforming to direct a first beam of radio frequency (RF) signal in a second frequency having a signal strength greater than a threshold to a first user equipment (UE) in motion, by use of the one or more second portions of the first antenna array, where the first frequency is different from the second frequency.

A method for estimating position of a mobile device which includes receiving, from a network server, observed time difference of arrival (OTDOA) assistance data for a first plurality of cells from a base station almanac (BSA) accessible to the network server. The OTDOA assistance data is stored, within a memory of the mobile device, as a first micro-BSA. A position estimate for the mobile device is determined based upon time difference of arrival (TDOA) measurements associated with an initial subset of the first plurality of cells and initial OTDOA assistance data corresponding to the initial subset of the first plurality of cells. The initial OTDOA assistance data may be generated by the micro-BSA based upon an initial seed estimate.

In one embodiment, a technique is provided for wireless position determination wherein identification information and positional information about wireless beacons are supplied from a central database maintained by a central facility to a wireless computing device, the identification information and positional information usable by a wireless positioning system of the wireless computing device to estimate a position of the wireless computing device. The central facility receives a contribution from the wireless computing device of identification information and positional information for at least one wireless beacon, the positional information of the at least one wireless beacon estimated based on the position of the wireless computing device. It updates the central database based on the identification information and positional information for the at least one wireless beacon and provides, from the central database, updated identification information and positional information about wireless beacons to at least one other wireless computing device.

Examples herein involve estimating a first position of a mobile device based on first communication signals, assigning a first set of particles to a number of respective first sampling locations within a threshold distance of the first position, adjusting the assignment of the first set of particles to second sampling locations based on movement of the mobile device, and estimating a second position of the mobile device based on the second sampling locations.

Systems and methods for WiFi mapping an industrial facility are disclosed. The system comprises a self-driving vehicle having a WiFi transceiver. The self-driving vehicle communicates with a fleet-management using the WiFi transceiver, via a WiFi access point. The self-driving vehicle receives a mission from the fleet-management system, and moves to a destination location based on the mission, using autonomous navigation. While executing the mission, the self-driving vehicle simultaneously measures the received signal strength indication of the WiFi access point and other WiFi access points in the facility, and stores the received signal strength indication in association with the location at which the received signal strength indication was measured.

To perform positioning by a computing device, a position request transmitted by a terminal is received. The positioning request includes target access point information obtained by the terminal. Then a plurality of first geographic grids related to a location of the terminal is determined based on the target access point information. A positioning sequence of the plurality of first geographic grids is determined according to access point information corresponding to the plurality of first geographic grids and the target access point information. The positioning sequence indicates distances between the plurality of first geographic grids and the terminal. The location of the terminal is then determined based on the positioning sequence of the plurality of first geographic grids and location information of the plurality of first geographic grids.

Techniques for calculating a location of a position consumer device is disclosed. In one example, a network server may create a fingerprint map from reference data points. Each of the reference data points may include a recorded geo-location of a position source device and signal measurements taken at that recorded geo-location. By initially estimating an initial position of the position consumer device, the network server may apply one or more threshold values to filter reference data points—candidates for interpolation. The network server may then perform an interpolation on one or more pairs of reference data points to find a pair of reference data points that is collinear with the estimated position of the position consumer device. The location of the position consumer device may then be calculated based upon geo-locations of position source devices that are associated with collinear reference data points.

It updates the central database based on the identification information and positional information for the at least one wireless beacon and provides, from the central database, updated identification information and positional information about wireless beacons to at least one other wireless computing device.

Methods and apparatus for assigning a role to a new lighting node in a lighting system based on a received signal strength indicator (“RSSI”) fingerprint of the new lighting node. For example, methods and apparatus described herein are directed to determining RSSI fingerprints for each lighting node in a lighting system, matching one of the RSSI fingerprints to the RSSI fingerprint of a new lighting node, and assigning a role to the new 5 lighting node. The assigned role is the same role as previously assigned to the matching lighting node.

A synthetic reception strength value in a case of synthesizing indirect waves of radio waves generated due to an obstruction is calculated for each piece of receive antenna coordinate information in consideration of a phase of each indirect wave. Relation information indicating relation between input information and teaching information is generated. The input information is the synthetic reception strength value for each piece of the receive antenna coordinate information corresponding to transmit antenna coordinate information. The teaching information is information indicating a reception state of the radio waves being calculated using a method of actually measuring the radio waves output by the transmit antenna at a position of a receive antenna or a method other than the method of the actual measurement. Strength of the radio waves is estimated by calculating the information indicating the reception state of the radio waves by using the transmit antenna coordinate information for evaluation and the generated relation information.
