A tracking system determines a location of a tracking device associated with a user using one or more access points at the location. Each access point at the location is configured to detect and couple with the tracking device when the tracking device is within a communicative range of the access point. An access point provides updates on the tracking device's presence, as well as the tracking device's arrival to and departure from the communicative range of the access point, to a tracking server. The tracking server determines, from these updates, whether the tracking device is at the location. The user may be notified, via a mobile device, of the tracking device's location.

Disclosed by the present application are a positioning method and apparatus, which are used to improve indoor positioning performance and precision without occupying a large amount of system resources. At a positioning server side, a positioning method provided by an embodiment of the present application comprises: acquiring a positioning capability supported by a user equipment (UE), and determining, according to the positioning capability, that the UE may obtain a positioning measurement value by means of detecting a positioning reference signal ioPRS that is used for indoor/outdoor positioning; acquiring positioning auxiliary data comprising ioPRS configuration data, and sending the positioning auxiliary data to the UE; acquiring the positioning measurement value that is provided by the UE and that is acquired on the basis of the ioPRS, and using the positioning measurement value to position the UE.

This application describes methods and system for positioning pico remote radio units. Drive test information on a terminal side and drive test information on a network management system side are recorded when a drive test is performed, and pico remote radio unit position information and a pico remote radio unit identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to facilitate positioning of a pico remote radio unit, and to ensure efficient system operation and maintenance.

A sales rotation system is disclosed that increases walk-up sales. The sales rotation system creates an equitable and efficient management of sales personnel on the dealership floor. The sales rotation system corrects one or more business issues with handling of walk-up sales including sales personnel bickering over who is up next in the rotation, track lead collection and close ratios, creating an automated way to notify a sales person when the sales person is up, digitally fence an up area and provide a notification when sales personnel who are up wander from the showroom entry, setting up a count to be flexible based on dealership volume and size, and improving customer experience by managing the number of sales personnel on the dealership floor and equitably rotating them.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for drone delivery. One of the methods includes: receiving, at the UAV, information about a location of a drop beacon comprising GPS coordinates of a location of a drop beacon; navigating the UAV towards the location based on the information using GPS coordinates of the drop beacon; when reaching a proximity of the drop beacon, transmitting a first radio signal from the UAV with information relatable by the drop beacon; receiving, at the UAV, a second radio signal from the drop beacon; identifying, at the UAV, a line-of-sight signal from the drop beacon; navigating the UAV to the drop beacon based on the line-of-sight signal; and delivering, from the UAV, the goods to the location of the drop beacon.

An apparatus and method of delivering an alert from an aircraft to a search and rescue system. An alert from an aircraft is received via a communications satellite. The alert comprises identification information identifying the aircraft and position information identifying the position of the aircraft. In response to receiving the alert, an emulated distress radio beacon signal is generated. The emulated distress radio beacon signal comprises the identification information and the position information in a standard format of a signal generated by a distress radio beacon. The emulated distress radio beacon signal is broadcast from a location other than the aircraft as an emulated distress radio beacon transmission that is configured to be received and processed by the search and rescue system.

A terrestrial based positioning system includes a plurality of location anchors configured to transmit and receive ultra-wide band (UWB) signals. In another aspect, a location tag configured to transmit and receive UWB signals uses signals transmitted by location anchors to determine its current position. In some implementations, a location tag may use Global Positioning System (GPS) signals or a combination of UWB and GPS signals to determine a current location. The location anchors are organized into zones used by the locations tags to determine a current position based in UWB signals. In some implementations, the locations anchors automatically create the necessary zones. Location anchors may also automatically determine the position of other location anchors. In yet other implementations, the location anchors relay data transmitted by a location tag. In addition, a location anchor may transmit GPS signals that can be used by standard GPS receivers.

A positioning method includes: sending, by a base station, indication information to a plurality of UEs, where the plurality of UEs have an MDT function in a cell covered by a to-be-positioned RRU, and the indication information is used to indicate the plurality of UEs to periodically report location information; obtaining, by the base station within each of at least one time period, time-of-arrival ToA measurement values of N UEs, where the N UEs are some UEs that report the location information in the plurality of UEs, N1, and N is an integer; and calculating, by the base station, a location of the to-be-positioned RRU based on M ToA measurement values obtained within the at least one time period and M pieces of location information that are in the received location information and that respectively correspond to the M ToA measurement values, where M3, and M is an integer.
