Abstract
A multi-radio wireless device capable of communicating on several wireless communication protocols (WCP) such as Wi-Fi, Bluetooth, etc. while avoiding on-device interference between radios operating using different WCPs. The device may measure an isolation value between radios during a calibration phase. During runtime operations, if a transmit activity is detected, the device may set a maximum receive gain using the expected transmit power and the isolation value. If a receive activity is detected, the device may set a maximum transmit power using an expected receive gain and the isolation value. The maximum receive gain and/or transmit powers may be obtained from a lookup table matching receive gain values to reference values where the reference values are a combination of transmit powers and isolation values.
