Description

[0001] The present invention relates to an in-building wireless service system using a TV cable network,

The present invention relates to a wireless service system in a building, and more particularly, it provides a mobile communication service using a TV cable network installed in a building such as a house, and further provides a wireless communication service such as Wi-Fi, Zigbee, And an integrated wireless service system capable of providing a communication service together.

Recently, as the spread of smartphones and tablets is increasing, data traffic of portable terminals is explosively increasing. According to statistics, it is known that more than 50% of traffic generated from portable terminals occurs in buildings.

Therefore, as the existing mobile communication network becomes difficult to cope with such traffic demands, it is known that mobile communication providers are actively planning to build a small communication network such as Femtocell while inducing traffic distribution through a Wi-Fi network have.

PAM Tocell is a very small mobile communication network provided through a pam-to-cell repeater that is connected to a base station and a wired network in a shaded area of a building. By utilizing a wired network, it is possible to reduce the cost of establishing a base station So that the satisfaction of the wireless service is increased.

Traditionally, the installation of pam tokens in the shaded areas of buildings has been costly in terms of efficiency. However, since the LTE (Long Term Evolution) service has been launched, data traffic is increasing more and more. Interesting.

Meanwhile, a WiFi service provided to a portable terminal is provided through a Wi-Fi access point (AP) (hereinafter referred to as "AP" for convenience), and most homes or buildings are provided with one or more APs connected to a wired Internet network .

The wireless service area of the AP is theoretically several hundred meters long. However, as the distance increases, the transmission speed is rapidly decreased and the actual serviceable area is known to be about 20 to 30 meters due to obstacles.

However, in the case of houses, the AP radio signal is more attenuated due to many walls and furniture due to its relatively narrow area, and there is a lot of signal distortion. Therefore, a shaded area in which wireless connection is not possible occurs, There is a problem such as a significant decrease.

This problem also occurs when a pamphlet repeater is installed in a house, and therefore it is urgent to prepare a solution for solving such a shadow area problem.

Also, most houses are provided with a broadcasting joint receiving facility (MATV) or a general wired broadcasting facility (CATV) in accordance with relevant laws and regulations. Specifically, as shown in FIG. 1, a household terminal box 50 is installed in each household A plurality of TV cables 40 branching from the household terminal box 50 are connected to the living room or the TV receptacle 30 installed in each room. At this time, each TV cable 40 is embedded in a wall or ceiling.

However, as the use of CATV / MATV facilities is lowered due to the recent spread of IPTV, it is necessary to use these facilities for new use.

The present invention aims to improve the quality of mobile communication and short-range wireless communication in a building using a TV cable network installed in a building. In particular, by minimizing the length of a wireless section by transmitting a mobile communication signal and a Wi-Fi signal to each room or a living room via a TV cable network, it is possible to solve the problem of speed reduction and connection failure due to walls, etc. The purpose.

Further, it is intended to transmit various wireless communication signals of different standards such as Zigbee together through a TV cable network to integrate various types of wireless services in a building, thereby reducing user installation cost and installation cost .

In order to accomplish the above object, the present invention provides a system for providing a wireless communication service using a TV cable network installed in a building, the system comprising: a television input line connected to an external MATV or CATV repeater; A femtocell repeater for outputting a mobile communication signal and a Wi-Fi signal; A plurality of TV cables installed in the building; A broadband distributor which combines the TV signal of the TV pull-in line with the mobile communication signal and the Wi-Fi signal of the femto-cell repeater, and distributes the combined signal to the plurality of TV cables and transmits the signal; Signal separating means for separating the TV signal, the mobile communication signal, and the Wi-Fi signal from the combined signal, respectively, connected to terminals of the plurality of TV cables, a TV connection port for outputting the TV signal, And an end device having an antenna for outputting the Wi-Fi signal and the mobile communication signal.

The present invention also provides a system for providing a wireless communication service using a TV cable network installed in a building, the system comprising: a TV distributor connected to an external MATV or CATV repeater through a TV lead; A first TV cable and a second TV cable separately installed in the building; A Femtocell repeater installed in the building and connected to an external wired network and outputting a mobile communication signal; A broadband distributor for combining a TV signal output from a first output terminal of the TV distributor and a mobile communication signal of the fomtocell repeater received through the second TV cable and outputting a combined signal to the first TV cable; A first signal splitting unit connected to an end of the first TV cable and separating the TV signal and the mobile communication signal from the combined signal received from the broadband splitter, A first terminal device having an antenna for outputting the mobile communication signal; A second signal separation unit connected to an end of the second TV cable for preventing interference between the TV signal and the mobile communication signal; a TV connection port for outputting the TV signal; And a second end device having communication means for communicating with the second end device.

In the wireless service system according to the present invention, the fomtocell repeater may further output a Wi-Fi signal, and the first signal separation means of the first end device may further comprise means for separating the Wi-Fi signal.

In addition, in the wireless service system according to the present invention, the communication means of the second end terminal includes an antenna for receiving a radio output signal of the fomtocell repeater, and the second signal separating means includes an antenna, And a signal amplifier is installed between the antenna and the filter.
