Abstract

PURPOSE:To realize the wiring system where a terminal equipment is moved and extended freely by arranging plural sub antennas freely movably in contact with or in the vicinity of a radio wave shield member and transmitting/receiving a radio wave with a main antenna. CONSTITUTION:The radio wave shield member 23 surrounding the main antenna 22 is placed on a floor 31 made of concrete. Moreover, a carpet 32 is placed thereupon and office desks or the like are placed and a terminal equipment (comprising a personal computer 20-1 and a telephone set 20-2) is placed. Each terminal equipment is connected to sub antennas 24-1, 24-2 via sub radio wave transceivers 21-1, 21-2, inserted to a member 23 through the carpet 32 and a radio wave is transmitted/received with the main antenna 22. The main antenna 22 is connected to a terminal board 34 via a main radio wave transmitter- receiver 11 and connected to an opposite information source via a PBX 36 connected to a node 35 and a public line. Thus, while radio wave interference or interception is being excluded, the radio wave is transmitted/received between the main and sub antennas.
