Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a communication system using a transceiver of a specific low power type which is integrally provided with a transmitting / receiving antenna.

[0002]

[Prior art and problems]

 Conventionally, a specified low-power transceiver based on the Radio Law requires that a transmitting / receiving antenna be integrated, and the transmission power of radio waves is also limited.

For this reason, for example, when communicating indoors or outdoors such as in a room of a building or in a basement, a wall that blocks the propagation of radio waves becomes an obstacle, and communication becomes impossible or communication is possible. There was a problem that the distance became extremely short, which hindered communication.

The present invention solves the problems existing in the prior art as described above. Communication is possible or a communication distance is dramatically increased even between communication areas separated by a wall that blocks transmission of radio waves. It is intended to provide a communication system that can be expanded to

[0005]

[Means for Solving the Problems]

 The communication system 1 according to the present invention comprises relay antennas 4a provided in a plurality of communication areas Aa partitioned by partitions W such as walls Wx ... And connection wirings 5i connecting the relay antennas 4a. .. and a plurality of transceivers 3p ... Used in the communication area Aa ..

In this case, one or more relays 2i are provided between each transceiver 3p, and each transceiver 3p is integrally provided with a transmission / reception antenna 6.

[0007]

[Action]

 According to the communication system 1 of the present invention, inside the communication area Aa ... With a partition W such as a wall Wx. Even if the transceivers 3p are present in the wireless communication, the radio waves transmitted from the respective transceivers 3p ... Are communicated through the relay antennas 4a .. Propagate to the area Aa ..., and the communicable distance or communicable distance between them is expanded. In this case, the configuration and function required for the specific low power type transceiver 3p ... Incorporating the transmission / reception antennas 6 ... Are not impaired.

【Example】

 Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

First, the configuration of the communication system 1 according to the present invention will be described with reference to FIGS. 1 and 2.

In FIG. 1, B indicates a building, which has an underground FB, a first floor F1 and a second floor F2. Further, in the building B, Wx indicates a second-floor wall, Wy indicates a second-floor floor, and Wz indicates a first-floor floor, which respectively form the partition W. On the other hand, C indicates an automobile existing away from the building B.

In the communication system 1, relay antennas 4a, 4b, 4c and 4d are respectively arranged in communication areas Aa, Ab, Ac and Ad partitioned by a wall Wx, a floor Wy and a floor Wz, and each relay antenna 4a, By connecting 4b, 4c, and 4d with the connection wiring 5i, the repeater 2i ... That is, as shown in FIG. 2, for example, a hole H 1 is formed in the wall Wx, a connection wiring 5i using a coaxial cable is passed through this hole H, and the connection wiring 5i is provided for each of the relay antennas 4a ... ), And each relay antenna 4a ... Is connected to each tip of the connection wiring 5i.

Further, relay antennas 4e and 4f are also provided on the partition of the automobile C, that is, on both sides of the roof Ww, and the relay antennas 4e and 4f are also connected by the connection wiring 5j in the same manner as above. Thus, the repeater 2j is configured. Therefore, the interior of the automobile C becomes the communication area Ae.

On the other hand, 3p and 3q are transceivers used in the respective communication areas Aa ... And are integrally provided with transmission / reception antennas 6. Each of the transceivers 3p ... Is a specific low power type transceiver based on the Radio Law.

Next, the usage method and function of the communication system 1 according to the present invention will be described with reference to FIGS. 1 and 2.

First, the transceivers 3p ... Can be used as they are in the communication area Aa ... In which the relay antennas 4a. The embodiment exemplifies a case where two transceivers 3p and 3q are used in communication areas Ab and Ae where relay antennas 4b and 4e are present.

In this case, the relay antennas 4b and 4a existing in the respective communication areas Ab, Aa and Ae, and further 4f, even if the wall Wx and the roof Ww which shield the propagation of radio waves are present between the respective communication areas Ab and Ae. Since 4 and 4e are connected via connection wirings 5i and 5j, respectively, the radio wave transmitted from the transceiver 3p propagates to other communication areas Ae through the repeaters 2i and 2j, and the radio wave transmitted from the transceiver 3q is also transmitted. , And is propagated to another area Ab so that the transceivers 3p and 3q can communicate with each other.

Although the embodiments have been described in detail above, the present invention is not limited to such embodiments, and the details of the configuration, shape, materials, etc. are within the scope not departing from the gist of the present invention. It can be changed arbitrarily.
