In such a case, the telephone facilities in the existing building may be available, but there are places where telephones are not installed, and telephones installed for other work should be dedicated to maintenance work. Is often impossible, even temporarily. Therefore, the maintenance workers need to communicate with each other at an unspecified plurality of locations, and it is desirable that each of them be contacted by a dedicated wireless communication device. Usually, for this purpose, it is classified as simple wireless under the Radio Law. For example, in the 150 MHz band or 450 MHz band, the qualification of a wireless worker is limited to a small number of fixed and mobile wireless sets that are transmitted and received by each area. Instead of being approved even if it is not approved, a radio communication device of a system that is subject to various regulations in order to efficiently use radio waves jointly, such as antenna power, antenna height, and talk time, seems to be appropriate.

In such cases, radio waves are shielded because a steel plate is usually used as a material. Since ordinary glass windows allow radio waves to pass relatively well, according to the results of experiments conducted by the present inventors, rooms facing the outside of a building, even on floors that are far away, cannot be compared with a building adjacent to the building. Wireless communication was possible between the rooms, but between rooms surrounded by walls, metal partitions, etc. inside the building,
These radio wave shields attenuate, for example, 50 dB or more, and communication with a simple wireless device was impossible. As can be understood from the application, a large and heavy wireless device with high performance is difficult to use for such a purpose, and is difficult to solve by improving the performance of the wireless communication device itself.

The no-power radio wave repeater 1 in the building according to the present embodiment is provided between a radio wave transmitting side such as the base station 6 and a radio wave receiving side such as the mobile phone 7.
When the radio wave shield 5 such as a floor, a wall, or a partition is present and communication cannot be performed, the radio wave shield 5 can be attached to the radio wave shield 5 to transmit a received radio wave to the opposite side. And can communicate with each other. The coaxial cable 3 is passed through the through hole 51 provided in the radio wave shield 5, and the antenna 2 is connected to both ends of the coaxial cable 3 using the connectors 4. As shown in FIG. 2, the non-powered radio wave repeater 1 in a building according to the present embodiment includes two antennas 2, a coaxial cable 3, a connector 4, and the like. The antenna 2 includes a frequency adjustment unit 21, an antenna body 22, and an antenna body support 2.
3, a reflector 24, a radiator 25, an auxiliary radiator 26, and the like. The frequency adjuster 21 adjusts the frequency transmitted and received by the antenna 2. The antenna main body unit 22 receives radio waves from the base station 6 or the like and converts them into signal currents, or converts the signal currents into radio waves and transmits them to the mobile phone 7 or the like. The antenna main body support part 23 supports the frequency adjustment part 21 and the antenna main body part 22, and mounts the reflector 24. The reflector 24 reflects radio waves when collecting radio waves from the base station 6 or the like and collects them in the antenna main body 22. When transmitting the radio waves to the mobile phone 7 or the like, the reflector 24 reflects rearward transmission radio waves. For example, an aluminum metal plate is bent twice to form a V-shape having a flat bottom 241, and the flat bottom 241 is attached to the antenna main body support 23. The opening angle of the V-shaped aluminum metal plate is preferably 90 degrees, and the angle with the antenna body 22 is 45 degrees. The antenna 2 is connected to both ends of the coaxial cable 3 via connectors 4. The connector 4 detachably connects the antenna 2 and the coaxial cable 3 to each other.
