Abstract: A method for active interference avoidance in unlicensed bands. The method includes receiving an electromagnetic signal having a transmission frequency, a transmission period, and an antenna pattern from a phased array antenna. The method also includes switching the transmission frequency from a first transmission frequency with a first signal to interference and noise ratio to a second transmission frequency with a second signal to interference and noise ratio, wherein the second signal to interference and noise ratio is lower than the first signal to interference and noise ratio. The method further includes selecting a transmission period based on a time when a least amount of signal noise is present on the transmission frequency and selecting an antenna pattern that reduces interference on the selected transmission frequency.
