  • Publication number: 20240413666
    Abstract: An example computing device includes a wireless communication device, such as a wireless wide area network (WWAN) communication device, that communicates in a first band of electromagnetic radiation, and a wireless charging system that wirelessly charges a peripheral device using a second band of electromagnetic radiation. The wireless charging system operating in the first band may introduce harmonic noise that negatively impacts communication in the second band. Accordingly, in various examples, the system operates to adjust the charge rate used by the wireless charging system based on a function of the charge state of the peripheral device and a received signal strength indicator (RSSI) value of a signal received by the wireless communication device. In some instances, the wireless charging rate of the peripheral device may be disabled or reduced when the RSSI value of the signal received by the wireless communication device is below a threshold value.

  • Patent number: 12119887
    Abstract: The present disclosure provides intelligent radio frequency interference mitigation in a computing platform. The computing platform includes a processor, a memory, a system clock and a wireless network interface. The system clock can be controlled so that the processor and/or the memory may operate at a slow frequency or a fast frequency. The wireless network may operate on a radio channel that experiences radio frequency interference at the fast frequency. The system clock may be intelligently controlled to select the slow frequency to reduce radio frequency interference to prioritize execution of a network application, or to select the fast frequency to increase processor speed and prioritize execution of a local application.

  • Publication number: 20230422187
    Abstract: The transmission power at which to drive an antenna of a computing device is adjusted based on a peak transmission gain of the antenna for a current physical configuration mode in which the computing device is operating and on a maximum permitted radiation for the antenna. The antenna is driven at the adjusted transmission power when performing wireless communication using the antenna.

  • Patent number: 11388682
    Abstract: In one example, a device may include a transceiver to receive a signal at a first transmit power from an access point via a wireless network connection. The first transmit power may be based on a feedback received signal strength indicator (RSSI) value. Further, the device may include a noise detection unit to determine device noise generated in the device and a signal-to-noise ratio (SNR) monitoring unit to determine that an SNR value associated with the wireless network connection falls below a threshold due to the device noise. Furthermore, the device may include a control unit to modify the feedback RSSI value upon determining that the SNR value falls below the threshold and transmit the modified feedback RSSI value to the access point via the transceiver.

  • Patent number: 11304192
    Abstract: An example electronic device includes a wireless transmitter and a controller. The controller is to: determine an active communication band; determine a parameter value of a proximity sensing circuit based on the active communication band; configure the proximity sensing circuit based on the parameter value; and set an output power of the wireless transmitter based on a detection signal asserted from the proximity sensing circuit. The wireless transmitter is to transmit data using the active communication band and the output power.
