Technologies directed to data transfer protocols for Ultra-Wideband (UWB) are described. One method includes a UWB radio of a first device receiving first data from an application. The first device sends data to second and third devices, the data identifying a number of data rounds, a duration of each round, a duration of a data slot, a duration of a data block, and a first slot index for the second device and a second slot index for the third device. The first device sends, during a first slot associated with the first slot index, the first data to the second device using the UWB radio. The first device sends, during a second slot associated with the second slot index, the first data to the third device using the UWB radio.

Methods and apparatus for providing quasi-licensed spectrum access within a prescribed area or venue, including to users or subscribers of one or more Mobile Network Operators (MNOs). In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum allocated by a Federal or commercial SAS (Spectrum Access System) to a managed content delivery network that includes one or more wireless access nodes (e.g., CBSDs) in data communication with a controller, and the core(s) of the MNO network(s). In one variant, the controller dynamically allocates (i) spectrum within the area or venue within CBRS bands, and (ii) MNO “roaming” users or subscribers to CBRS bands (e.g., via extant LTE-TD technology). In one particular implementation, the managed network comprises a Multiple Systems Operator (MSO) network such as a cable or satellite network, and the MSO and MNO coordinate to implement user-specific and/or data-specific policies for the roaming MNO subscribers.

The present disclosure discloses a method and a device for extracting broadband error calibration parameters, and a computer-readable storage medium. The method includes: performing frequency band splitting on link broadband signals of an ultra-wide band system according to a received frequency band index table to generate sub-bands; extracting an amplitude error and a phase error of each sub-band; and iteratively weighting and accumulating, according to the frequency band index table and a preset broadband weight table, the amplitude error and the phase error of each sub-band one by one to an initial amplitude error compensation parameter and an initial phase error compensation parameter respectively, to synthesize and extract broadband error calibration parameters. The present disclosure can adaptively match a working bandwidth of the current ultra-wide band system, and perform iterative solution on error parameters of a working area in real time, thereby having the advantages of ultra-wide band, high performance, low power consumption and high flexibility.

Disclosed herein are systems and methods related to a wireless tracking system: The wireless tracking system having a plurality of beacons, each of the plurality of beacons having at least one antenna and at least one power source. When the at least one antenna is supplied with power via the power source, a local ping is transmitted from the beacon. A wireless tracking device then receives the ping via its own antenna. Once the wireless tracking device has received a locational ping from at least two of the plurality of beacons, it can then calculate a direct connection path between the at least to beacons. Based on this known path, the wireless tracking device can then determine a distance between the wireless tracking device and connection path. Based on the determined distance, the wireless tracking device may then issue a corrective measure.
