  • Patent number: 11985012
    Abstract: The embodiments described herein are directed at techniques to de-correlate Bluetooth interference seen across WLAN receive antennas/space in a Bluetooth transceiver/WLAN transceiver combination device. A Bluetooth interference whitening technique may be utilized, wherein a whitening matrix is computed based on a leakage signal resulting from a training signal transmitted by the Bluetooth transceiver. The leakage signal may leak in to the WLAN transceiver and a set of attributes is calculated for each frequency the leakage signal is received on. One or more whitening matrixes are calculated based on the set of attributes for each frequency the leakage signal is received on. In response to the WLAN transceiver receiving a signal of interest, an appropriate whitening matrix from the one or more whitening matrixes is selected and is then applied to the received signal of interest to de-correlate any interference generated as a result of the Bluetooth transmission.

  • Publication number: 20230108231
    Abstract: A method can include, in a wireless device connected to a first network and configured to transmit over a medium, while a detected packet is being received: determining if the detected packet has a network identification value, the network identification value identifying a network in which wireless devices are connected; when at least the network identification value of the detected packet matches that of the first network, setting a timer value that prevents transmissions on the medium by the wireless device during the duration of the detected packet; and when at least the network identification value of the detected packet does not match that of the first network, dropping the detected packet before it is fully received and not setting the timer value.

  • Patent number: 11272382
    Abstract: Systems, methods, and devices reduce interference experienced by wireless communications devices. Methods include receiving a first signal from a first transceiver, the first signal being compatible with a first communications protocol, and configuring a filter based, at least in part, on the received first signal, the filter being communicatively coupled to a second transceiver collocated in a same wireless communications device as the first transceiver. The methods further include receiving a second signal, the second signal being compatible with a second communications protocol, and filtering the second signal to remove at least some components of the first signal from the second signal, the filtering reducing at least some interference from the first signal with the second signal. The methods also include providing the filtered second signal to the second transceiver.

  • Patent number: 10893483
    Abstract: A system and method are provided for extending range of devices in a legacy wireless network. Generally, the method involves providing in a transmitter of the system a frame having a first field including a number of preamble segments and a second field including a number of data segments. The transmitter in the system is then operated to transmit at least one of the preamble segments with at least a first transmit power, and to transmit the segments of the second field at a second transmit power, wherein the first transmit power is greater than the second transmit power. Other embodiments are also described.
