본 발명은 공동주택의 이동통신 중계시스템에 관한 것으로, 더욱 상세하게는 다층으로 이루어진 아파트 등과 같은 공동주택에 있어서, 건물의 외측에 외부안테나와 이동통신중계기 및 케이블신호와 이동통신신호를 접속시키는 외부접속기를 구비하고 각 댁내에 커플링된 신호를 분리시키는 실내접속기와 실내안테나를 구비하여서 아파트와 같이 다층 또는 고층으로 이루어져 있어 이동통신기기의 송수신이 잘이루어지지 않는 곳에서 이동통신기기를 용이하게 사용할 수 있도록 함을 목적으로 한 것이다.The present invention relates to a mobile communication relay system of a multi-unit house, and more particularly, in a multi-unit house such as a multi-layer apartment, an external antenna and a mobile communication repeater and an external terminal connecting a cable signal and a mobile communication signal to the outside of the building. Equipped with a multi-layered or high-rise building such as an apartment with an indoor connector and an indoor antenna for separating the signals coupled in each home, it is easy to use mobile communication devices in places where transmission and reception of mobile communication devices are difficult. The purpose is to make it possible.

일반적으로, 아파트 등과 같은 공동주택에는 각 댁내에서 별도의 방송수신용 안테나를 설치하지 않아도 방송를 시청할 수 있게 동축선로가 설치되어 있으므로 각 댁내의 벽면에 구비된 안테나커넥터에 안테나케이블만 연결하므로서 방송를 시 청할 수 있는 것이다.In general, apartment houses such as apartments have coaxial lines installed so that users can watch broadcasts without having to install a separate antenna for receiving broadcasts. Therefore, only the antenna cable is connected to the antenna connector provided on the wall of each house to watch broadcasts. It can be.

한편, 상기한 바와 같이 각 댁내에까지 방송수신을 위한 동축선로가 설치된 아파트등과 같은 고층의 공동주택은 안테나가 하향지향성을 가지게 설치되는 기지국의 특성상 일정 층수가 되면 기지국의 영향권에서 벗어나 이동통신기기의 송수신이 이루어지지 않으며, 저층의 경우에도 철근 콘크리트로 이루어지는 구조물의 특성상 전파의 송신이 약화되어 이동통신기기의 송수신이 잘 안이루어지는 문제점이 있어, 이의 해결을 위하여 각 댁내마다 이동통신기기의 원활한 송수신을 위한 별도의 소형중계기를 설치하여서 그 문제를 해결하고 있다.On the other hand, as described above, high-rise apartments such as apartments, which have coaxial lines for broadcasting reception to each house, are separated from the area of influence of the base station by a certain floor due to the characteristics of the base station where the antenna is installed in a downward direction. There is a problem that the transmission and reception is not made, and even in the case of low floor, the transmission of the radio wave is weakened due to the characteristics of the structure made of reinforced concrete, so that the transmission and reception of the mobile communication device is not easily performed. The problem is solved by installing a separate small repeater.

그러나, 상기한 바와 같이 각 댁내에 소형중계기를 설치하는 것은 막대한 비용이 소요되고 근접한 댁내에 설치된 소형중계기간의 전파간섭에 의하여 마이크의 하울링과 같은 소리울림 현상등이 발생하여 그 음질이 저하되는 등의 문제점이 있었다.However, as described above, the installation of a small repeater in each house takes enormous cost, and the sound quality such as howling of the microphone occurs due to the radio interference of the small repeater period installed in the adjacent house. There was a problem.

이에, 본 발명은 상술한 바와 같이 아파트 등과 같은 공동주택에 있어서 기지국 안테나의 지향성과 건물벽체로 인한 수신감도 저하로 인한 이동통신기기의 송수신기능 저하의 문제점을 해결할 수 있도록 한 것이다.Therefore, the present invention is to solve the problem of the transmission and reception of the mobile communication device due to the decrease in the reception sensitivity due to the directivity of the base station antenna and the building wall in a multi-family house such as an apartment as described above.

즉, 본 발명은 다층으로 이루어진 아파트 등과 같은 공동주택에 있어서, 건물의 외측에 외부안테나와 이동통신중계기 및 케이블신호와 이동통신신호를 접속시키는 외부접속기를 구비하고 각 댁내에 커플링된 신호를 분리시키는 실내접속기와 실내안테나를 구비한 것이다.That is, the present invention, in a multi-family apartment, such as a multi-storey apartment, having an external antenna, a mobile communication repeater and an external connector for connecting a cable signal and a mobile communication signal on the outside of the building, and separates the signals coupled to each house. It is equipped with an indoor connector and an indoor antenna.

따라서, 본 발명은 아파트와 같은 공동주택에 저역의 방송신호와 고역의 이동신호를 커플링 접속하는 외부접속기와 커플링 접속된 신호를 분기하여 실내안테나로 이동통신신호를 전송할 수 있게한 실내안테나로 이루어진 통신선로시스템을 구축하므로서 기지국 안테나의 하향지향성과 구조물의 특성으로 인한 이동통신기기의 송수신불량이 양호하게 이루어지는 것으로서 이동통신기기의 송수신을 위한 별도의 이동통신중계기의 설치등을 하지 않아도 되는 것이다.Accordingly, the present invention provides an indoor antenna that can transmit a mobile communication signal to an indoor antenna by branching a signal connected to an external connector coupled to a low-frequency broadcasting signal and a high-frequency moving signal to a multi-unit house such as an apartment. By establishing the communication line system, the transmission and reception of the mobile communication device due to the downward direction of the base station antenna and the characteristics of the structure is made good, and it is not necessary to install a separate mobile communication repeater for transmitting and receiving the mobile communication device.
