In-service fade margin measurement

Methods may include alerting fixed service microwave operators that their network has been compromised due to interference, before their service is necessarily impacted. In an example, method may include receiving instructions to test fade margin for a wireless communication link associated with a receiver radio, wherein the wireless communication link is passing live traffic; testing the fade margin while the wireless communication link is passing the live traffic; receiving error information, wherein the error information is based on an error correction mechanism for the wireless communication link; based on the error information, determining that a threshold number of errors has been reached; and sending an alert based on the threshold number of errors.
