摘要： A system includes a transceiver configured to receive frequency dependent channel estimates or beamforming feedback in a multi-carrier, multi-antenna communication system, and a multi-layer perceptron feed forward neural network component, coupled with the transceiver, configured to estimate parameters of multipath reflections using representations of the channel estimates or beamforming feedback, and to generate transmission correction factors for the transceiver.

摘要： Techniques are disclosed to leverage co-located radios such as BLE and Wi-Fi radios to increase the security of BLE ranging and localization. In one aspect, a transmitting BLE device may use a co-located Wi-Fi radio to transmit signals to interfere with an intruding device's interception of BLE RTT packets. The obfuscating Wi-Fi transmission may overlap a BLE RTT packet in the time domain with or without overlapping in the frequency domain. In one aspect, the co-located Wi-Fi radio may transmit pre-determined signature Wi-Fi signals concurrently with the BLE RTT packets to a receiver with co-located BLE and Wi-Fi radios. The receiver may detect a change in the pre-determined relationship between the two types of communication to reveal an intrusion attempt. In one aspect, a co-located Wi-Fi radio may capture parts of BLE RTT packets concurrently with a BLE radio transmitting or receiving BLE RTT packets to detect an intrusion attempt.

摘要： Systems, methods, and devices detect radio frequency identification devices. Methods include transmitting a signal from a transmitter of a wireless device compatible with a wireless communications protocol, receiving, using a receiver of the wireless device, an encoded signal from a radio frequency identification (RFID) device, and determining a plurality of data values based, at least in part, on the received encoded signal. Methods further include generating an estimated distance value based, at least in part, on the received encoded signal, the estimated distance value representing an estimate of a distance between the wireless device and the RFID device.

摘要： A multi-protocol network and methods for operating the same are provided. The method begins with establishing a wireless-connection between a first transceiver in a first device and a second-transceiver in a second device using a wireless-protocol. First, wired-protocol packets and non-packet data are received and converted in the first device to second-packets compatible with the wireless-protocol by inserting synchronization-bits non-packet data in a preamble field. This is initiated by sensing arrival of the preamble without waiting for a start of data. The second-packets are transmitted from the first transceiver to the second, and converted to third-packets compatible with the wired-protocol by removing the synchronization-bits. Latency is improved by initiating/starting a packet to the wired controller before a data portion of the packet is received. The number of synchronization bits is selected so the second-packets are aligned and synchronized with wireless-protocol packets.

摘要： A multicarrier phase ranging system and method are provided. Generally, the method includes performing a handshake between first and a second transceiver to negotiate a list of channels and a start-time for a multicarrier phase ranging process. The process includes in a first cycle exchanging a Constant Tone (CT) between the first and second transceiver in a first epoch on a first channel, and processing the CT received in the first and second transceiver to measure a difference in phase between the CT received and a reference signal. The CT received is checked for interference using software or hardware in either or both of the first and second transceiver. If no interference is detected the first and second transceiver switch to another channel and exchange the CT at a next epoch. If interference is detected, at least one channel is skipped for at least a subsequent epoch.

摘要： A system and method for an efficient secure phase-based ranging using loopback calibration, including receiving, by a reflector during a current timeslot, an incoming constant tone (CT) signal having a phase shift; determining, by the reflector during the current timeslot or a previous timeslot, a phase shift correction value by using a receiver/transmitter (Rx/Tx) loopback path of the reflector; and/or generating, by the reflector, an outgoing CT signal having an updated phase shift by adjusting the phase shift of the incoming CT signal based on the phase shift correction value.

摘要： One or more computing devices, systems, and/or methods are provided. In an example, a charging apparatus includes a charging surface, a magnetic charging interface comprising a magnetic charging element configured to generate a charging signal proximate the charging surface, and a magnetic communication interface separate from the magnetic charging interface. A processor is configured to execute instructions to receive a charging parameter using the magnetic communication interface and to control the charging signal via the charging element during a charging session based on the charging parameter.
