Zusammenfassung:PROBLEM TO BE SOLVED: To remove multipath phasing by a system in which performs wireless communication is performed between a plurality of antenna assemblies installed in a ceiling part in a building. SOLUTION: The communication system comprising floor reflection type antennas installed in the ceiling of a room and a mesh net has a structure such that the antennas having an adjusting means for reducing the generation of multipath reflected by a floor, furniture, etc., by adjusting the positions of the antennas with directivity are used and the antennas can be moved horizontally and vertically for position adjustments. Further, the antennas with directivity are composed of colinear or MSA antennas. COPYRIGHT: (C)2007,JPO&INPIT
