Title:
WIRELESS PRIVATE COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2015142305
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless private communication system in which a radio signal is prevented from being propagated to the outside of a building, communication can be performed with a required and sufficient intensity inside of the building and interference with another wireless private communication network or the like is prevented from being generated.SOLUTION: The wireless private communication system includes: an access point 3, a router 7 and a distributor 9 which are installed within an information distribution board 2; RF cables 4a-4n electrically connected with the access point 3 via the distributor 9; and transmit/receive antennas 6a-6n installed within outlet plates 5a-5n and electrically connected with the RF cables 4a-4n, respectively. A communication distance with a radio communication terminal is about several meters (e.g., three meters). Therefore, a radio signal transmitted from the radio communication terminal can be received with a high intensity, and interference caused by a radio signal transmitted from the outside of a building can be prevented.
