Publication number: 20240098655Abstract: Techniques described herein are directed toward smart external interference detection and avoidance. An example method includes determining a first received signal strength indicator (RSSI) value of a received first signal across a radio band, wherein the first RSSI value is based at least in part on a second signal transmitted by an interfering device. The first received RSSI value is compared with a threshold value. A first gain adjustment value is determined for a receiver chain of the first computing device and a second gain adjustment value of a transmitter chain based at least in part on the comparison. A first gain of a first amplifier of the receiver chain is adjusted based at least in part on the first gain adjustment value. A second gain of a second amplifier of the transmitter chain is adjusted based at least in part on the second gain adjustment value.Type: ApplicationFiled: September 19, 2022Publication date: March 21, 2024Applicant: Apple Inc.Inventors: Sathish Shanbhag Kota, Vijay Kumar Ramamurthi, Vijaykrishnan Ramakrishnan
