In one embodiment, a momentary reduction of transmitter power is noted during which putative interference is measured at the receiver. In another embodiment, an isolated burst is sent from a not-yet commissioned transmitter to contemporaneously detect possible interference at an operating receiver. A third embodiment can be used to measure and mitigate interference from a stationary mobile transmitter. A fourth embodiment establishes hosting for potential interference recognition as a service. | ||||||
