  • Patent number: 10891248
    Abstract: A method for communicating between a combo-endpoint device, wireless router and a wireless communication device includes monitoring communication patterns of wireless data communications between a wireless router and radio-communication circuitry of a combo-endpoint device, and storing data indicative of communication times of the wireless router based on the monitored communication patterns. The method further includes configuring a frequency-hopping(FH)-based protocol by defining connection periods according to time windows and selected frequencies for wireless communication of data between the wireless communication device and the radio-communication circuitry, and by establishing the time windows to not substantially conflict with the communication times of the wireless router.

  • Patent number: 10734961
    Abstract: A receiver includes at least a first amplifier configured to receive a received signal and provide a first amplified signal based thereon, a mixer configured to receive the first amplified signal and provide an intermediate frequency signal based thereon and a second amplifier configured to receive the intermediate frequency signal and provide a second amplified signal based thereon. An automatic gain controller for the receiver is configured to, based on a first overload signal indicative of a first frequency range of the first amplified signal having one or more frequency components exceeding a first maximum signal power threshold and a second overload signal indicative of a second frequency range, narrower than the first, of the second amplified signal having one or more frequency components exceeding a second maximum signal power threshold, provide for control of a respective gain of one or both of the first amplifier and the second amplifier.

  • Patent number: 10581474
    Abstract: Wireless receivers and related methods with interferer immunity are disclosed. The receiver includes a receive (RX) front-end, a power level detector, and an automatic gain controller (AGC). The RX front-end includes circuit(s) having variable gains, and the power level detector outputs a power level indicator. The AGC receives the power level indicator and outputs the gain settings to the variable-gain circuits within the RX front-end. Further, the AGC is configured to adjust the gain settings within a first gain range when not receiving data frames and to adjust them within a second gain range when receiving data frames. The second gain range is a restricted version of the first gain range. Further, the AGC can be configured to detect and store gain settings within a sliding time window when data frames are not being received and to use these stored gain settings to determine the second gain range.

  • Publication number: 20170208623
    Abstract: A wireless communications system and method are described. The system includes first and second stacks of respective first and second wireless communications protocols, a wireless interface to transmit and receive wireless signals, and useable by the first and second stacks, and an arbitrator is in communication with the first and second stacks. The first stack is configured to determine a first priority associated with a current message to be transmitted or received using the wireless interface and the second stack is configured to determine a second priority associated with a current message to be transmitted or received using the wireless interface. The arbitrator is configured to control which one of the first stack and the second stack can use the wireless interface based on which of the first priority and the second priority is higher.
