Abstract
A control unit (22) controls a filter (30) of a communication device (3a) by wired communication via a LCX (4a) to pass or cut off a signal in a wireless frequency band, to cause the LCX (4a) and LCX (4b) to function as a single antenna or a plurality of antennas.
Claims10
An information communication device comprising:
- a wired communicator to perform wired communication with a plurality of communication devices via a plurality of leaky coaxial cables connected to filters each provided in the plurality of communication devices;
- a wireless communicator to transmit and receive a signal in a wireless frequency band, using the leaky coaxial cable as an antenna;
- a signal mixing/separator to mix signals from the wired communicator and the wireless communicator and output the mixed signal to the leaky coaxial cable, and to separate signals received from the leaky coaxial cable into a signal provided to the wired communicator and a signal provided to the wireless communicator;
- and
- a controller to control the filters of the communication devices by wired communication via the leaky coaxial cable to pass or cut off the signal in a wireless frequency band of each of the filters of the communication devices to cause the plurality of leaky coaxial cables to function as a single antenna or a plurality of antennas.

An information communication method comprising:
- confirming, by a controller, a communication status of a wireless communicator;
- determining, by the controller, a leaky coaxial cable caused to function as an antenna, of a plurality of leaky coaxial cables connected to filters each provided in a plurality of communication devices in accordance with the communication status of the wireless communicator;
- and
- controlling, by the controller, the filters of the communication devices by wired communication via the leaky coaxial cable to pass or cut off a signal in a wireless frequency band of each of the filters of the communication devices to cause the leaky coaxial cable selected in the determining step to function as an antenna.
