摘要： A method is presented for disconnecting a wireless time-division duplex communication link between two nodes. A first node transmits during time slots allocated to the first node and the second node transmits during separate time slots allocated to the second node. The first node transmits at differing respective frequency bands during its time slots. The method includes: sub-dividing a time slot allocated to the first node into consecutive time intervals; and transmitting respective disconnect signals during the time intervals. Each of the disconnect signals is transmitted on a frequency band used by the first node. The disconnect signals are transmitted on different frequency bands during at least two of the time intervals.

摘要： A method of detecting repetitive information in data packets communicated between a first node and a second node over a wireless network, which may include collecting samples of a data communication signal transmitted between said first node and said second node over said wireless network at a plurality of respective times; grouping said collected samples into a plurality of sequences of samples; combining said plurality of sequences of samples into at least one united signal; and based on an analysis of said at least one united signal, providing a signal indicative of repetitive information in a plurality of data packets carried by said data communication signal.

摘要： 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.
