RADIO-BASED DETECTOR AND METHOD TO PROTECT AGAINST UNPREDICTABLE INTERFERENCE IN INDUSTRIAL WIRELESS COMMUNICATIONS

摘要

A method, a node and a detector for detecting an interfering signal in a wireless network communication system comprising a network manager and several nodes,each node (202B) comprising a detector (204) for receiving input signals from at least one antenna, a delay component (205) for delaying a received input signal,and a receiver (206RX) for determining an energy pattern of expected received input signals. The detector (204) is configured to send an alarm signal to the receiver (206RX) depending on the presence or absence of an interfering signal from an interferer 203 and an active/inactive state of the receiver (206RX).
