Abstract [en]

NOVELTY - Involves enabling one node in the system to function as a central node which can make measurements on a frequency in a frequency band used by the system. The measurements detect if a frequency is being used by a transmitter foreign to the system. USE - For use in a wireless communications system with several broadcasting nodes e.g. Wireless Local Area Network (WLAN). ADVANTAGE - Enables WLAN to detect if e.g. nearby radar system transmitter is using same frequency and to take necessary steps if so. DETAILED DESCRIPTION - The measurement is enabled by the central node transmitting a message to other nodes in the system. The message is predefined within the system as a message prohibiting all nodes from transmitting during a certain interval. DESCRIPTION OF DRAWING(S) - The drawing shows the signaling used when making measurements according to the method.
