Wireless communication node adapted to radiate antenna beams of different types

Abstract:

A wireless communication node comprising an antenna arrangement that is adapted to radiate at least one radiation beam of a first type and at least one radiation beam of a second type. Said at least one radiation beam of the first type has a first type beamwidth (B.sub.T1) and said at least one radiation beam of the second type has a second type beamwidth (B.sub.T2) that exceeds the first type beamwidth (B.sub.T1). Said at least one radiation beam of the first type is arranged for communication with at least a first other node, and where said at least one radiation beam of the second type is arranged for detection of changes in propagation paths for said other node and/or appearances of further other nodes.
