Examples of electronic devices are described herein. In some examples, an electronic device includes a transmitter. In some examples, the transmitter may transmit a first beacon and a second beacon. In some examples, the first beacon may be associated with a first account. In some examples, the second beacon may be associated with a second account. In some examples, the first account includes a different beacon control privilege relative to the second account.

Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A control device can monitor UWB ranging between a mobile device and a primary anchor. In response to determining that a signal strength between the mobile device and the primary anchor is below a threshold, the control device can identify anchors for which the mobile device has had a signal strength above the threshold during a period of time, and select one of the anchors as a new primary anchor for the mobile device. For example, the control device can select the new primary anchor based on a relative collision tolerance mapping for the new primary anchor and at least one other anchor within a UWB range of the new primary anchor. The control device can send a command causing UWB ranging to be performed between the mobile device and the new primary anchor.

An apparatus for a wireless communication system is provided. The apparatus is to transmit a reference signal on a common set of resource elements (REs), the common set of resource elements being used by one or more further apparatuses in the wireless communication system, so that the reference signal of the apparatus and one or more further reference signals of the one or more further apparatuses use the same resource elements. Moreover, the apparatus is to transmit the reference signal depending on a base sequence or a sequence derived from the base sequence and depending on a set of configuration parameters.

Deployable navigation beacons can be deployed from a vehicle, such as an unmanned aerial vehicle (UAV), in an event of a loss of position or orientation of the vehicle. After deployment of the navigation beacons, the vehicle may detect locations of the navigation beacon, which may define a surface that may include surface features. The vehicle may then perform control operations based on the resolved locations. For example, UAV may maneuver to land proximate to the navigation beacons after resolving locations of the navigation beacons as a continuous surface. The navigation beacons may output a visual signal (e.g., a light), a auditory signal (e.g., a sound), and/or a radio signal. In some embodiments, each navigation beacon may include a different or unique signal.

Disclosed is a radio-visual approach for device localization. In particular, a mobile device may receive, via radio signal(s) emitted by transmitter(s) in a vehicle that is substantially proximate to the mobile device, radio data that represents vehicle information associated with the vehicle, and may then determine or obtain a location of the vehicle in accordance with that vehicle information. Also, the mobile device may capture an image of the vehicle and may use that image as basis for determining a relative location indicating where the mobile device is located relative to the vehicle. Based on the location of the vehicle and on the relative location of the mobile device, the mobile device may then determine a location of the mobile device.

A receiver includes an RF module to receive and down convert multiple types of RF signals received from at least one antenna; a communication unit configured to communicate signals with at least one external device; and a processing unit communicatively coupling the radio frequency module with the communication unit. Processing unit receives operation mode selection. When first operation mode is selected, processing unit receives first input signal from antenna via RF module (the first input signal including ILS signal and/or VOR signal) and outputs first output signal based on first input signal to external device. When second operational mode is selected, processing unit receives second input signal from antenna via radio frequency unit (second input signal including AIS signal including data regarding a current location of remotely located transmitting device) and outputs second output signal based on second input signal to external device.
