INTERFERING IN TIME-DIVISION DUPLEX COMMUNICATION

A method for disconnecting a wireless time-division duplex communication link. The time-division duplex communication link being between a first node transmitting during time slots allocated to said first node, wherein a second node is transmitting during separate time slots allocated to said second node, said first node transmitting at a respective one of a plurality of frequency bands during each of said time slots allocated to said first node. The method may include sub-dividing a time slot allocated to said first node into consecutive time intervals; disrupting communication between said first node and said second node by transmitting, using a transmitter, respective interference signals during at least some of said time intervals while maintaining a frequency difference between any pair of consecutive interference signals below a frequency difference threshold, each of said interference signals being transmitted on one frequency band selected from a group of frequency bands, the group of frequency bands comprises the plurality of frequency bands, wherein for at least two of said time intervals said interference signals are transmitted on different frequency bands, wherein the frequency difference threshold does not exceed a portion of a frequency gap between (a) a lowest frequency band of the plurality of frequency bands and (b) a highest frequency band of the plurality of frequency bands.
