BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repeater, and more particularly, to an outdoor repeater having an integral antenna.

 As the number of subscribers of wireless communication service increases, the number of base stations has increased significantly for smooth operation of services, but the environment of wireless communication service is very unstable, so there is still a shadow area where radio waves can not reach.

These shaded areas are directly related to customers' service satisfaction, and service providers are investing a lot of money and efforts to remove shaded areas.

On the other hand, the most efficient way to remove shadow areas is to use a repeater that can relay signals between the communication network and the user (terminal).

Conventional service providers maximize the service by arranging various types of repeaters in areas that are considered to be in the shaded areas. Among them, the outdoor repeaters are installed with repeaters and antennas separately.

1 and 2 are views showing a conventional outdoor type repeater.

As shown in FIG. 1, the conventional outdoor type repeater can be installed on a roof or a pillar of a building. Since a repeater and an antenna are separately installed and operated, not only installation and operation costs but also a considerable time .

In one embodiment, the plurality of components included in the repeater circuit portion include a power supply for supplying power supplied from the outside, an amplifier for amplifying a signal, and a filter for filtering a frequency signal of a specific band, The supply unit and the amplification unit are disposed at a lower portion of the main body case, and the filter unit is disposed at a higher position than the power supply unit and the amplification unit.

In one embodiment, the antenna includes an articulated link structure that freely adjusts direction and angle, and uses the articulated link structure to extend the length.

In one embodiment, the antenna includes a first antenna for transmitting and receiving signals between the outdoor type repeater and a communication network, and a second antenna for transmitting and receiving signals between the outdoor type repeater and the terminal, Are integrally formed on different surfaces of the main body case.

According to an embodiment of the present invention, the cost and time required for installation and operation of the repeater can be saved. Further, the heat generated inside the sealed relay can be efficiently cooled.

According to an embodiment of the present invention, the direction and angle of the antenna can be arbitrarily adjusted, and the isolation of the donor antenna and the service antenna can be improved by the shielding effect of the repeater.

3 is a diagram illustrating a configuration of an outdoor type repeater according to an embodiment of the present invention.

The outdoor repeater 100 according to an embodiment of the present invention may include a repeater circuit unit 110, a main body case 120, and an antenna 130.

The repeater circuit unit 110 is located in the main body case 120 and is connected to the antenna 130 so that the downlink signal and the uplink signal can be relayed between the communication network and the terminal.

The repeater circuit unit 110 can perform basic signal processing required for relaying signals such as frequency conversion and amplification of signals. To this end, the repeater circuit unit 110 includes a power supply unit 111 for supplying power supplied from the outside to the main body of the repeater, An amplification unit 112 for amplifying a signal and a filter unit 113 for filtering a frequency signal of a specific band, and the like.

The power supply part 111 or the amplification part 112 generating a lot of heat can be disposed in the lower part of the main body case 120 in the repeater circuit part 110 and the filter part 113, May be disposed at a position higher than the power supply unit 111 and the amplification unit 112, that is, at an upper portion in the main body case 120. [

The filter unit 113 disposed at the upper portion of the main body case 120 is connected to the antenna 130 formed integrally with the main body case 120. The main body case 120 has a closed structure for waterproof, 120 can be efficiently cooled and the possibility of malfunction or breakage of the repeater circuit unit 110 due to the component overheating phenomenon can be prevented.

In addition, the repeater circuit unit 110 removes the oscillation of signals received from either the communication network or the terminal while relaying the downlink signal from the communication network to the terminal or relaying the uplink signal from the terminal to the communication network .

Meanwhile, the main body case 120 shields the repeater circuit unit 110 from the outside and can be electrically grounded.

The main body case 120 may be integrally formed with the antenna 130, and a plurality of antennas for transmitting and receiving signals in both directions may be integrally formed on different surfaces of the main body case 120.

The antenna 130 is connected to the filter unit 113 disposed at the upper portion of the main body case 120 and may be formed integrally with the main body case 120.

Here, the antenna 130 may include a first antenna for transmitting / receiving signals between the repeater 100 and the communication network, and a second antenna for transmitting / receiving signals between the repeater 100 and the terminal, And may be formed on different surfaces of the body case 120.

Specifically, the first antenna may be integrally formed on the upper surface of the main body case 120 so as to receive the downlink signal from the communication network or transmit the uplink signal transmitted from the repeater circuit unit 110 to the communication network.

The second antenna may be integrally formed on the other surface of the main body case 120 to receive an uplink signal from the terminal or transmit the downlink signal transmitted from the repeater circuit unit 110 to the terminal.

In addition, the antenna 130 may extend in a joint-shaped link structure in a state where the antenna 130 is integrally formed on the upper portion of the body case 120.

Here, the 'joint type link structure' can use a known technique as a structure capable of tilting or rotating the antenna in any direction and angle.

That is, since the upper and lower ends of the antennas connected to each other are connected to each other by a joint type link structure, the direction and angle of the antenna can be freely adjusted and the direction of the antenna can be easily adjusted according to the installation location.

4 is a diagram illustrating an outdoor type repeater according to an embodiment of the present invention.

Compared with the conventional outdoor type repeater shown in FIG. 1, the repeater and the antenna are formed integrally so that the installation cost, the operation cost and the installation space can be saved, and the installation work time can be shortened.

Also, it can be seen that the direction and angle of the antenna can be freely adjusted by connecting and extending the antenna of the repeater by a joint type link structure.

FIG. 5 is a diagram for explaining improvement of heat of the equipment and reliability of the equipment.

In FIG. 5, the mean time to failure (MTTR) is the time from failure to repair (recovery) when a part, device or computer system is operated. Mean time to failure (MTTF) It can not be repaired.

Also, Mean Time Between Failure (MTBF) is a measure of how much time is lost when a component, device, or computer system is operated, ie, how long the breakdown time is, MTBF = MTTF + MTTR.

For reference, MTTF is used when repair is impossible, and MTB is used when repair is not possible.

MTBF and MTTF are important concepts used to analyze faults, identify their causes, and estimate reliability of parts, devices, or computer systems.

Here, the MTTF increases with lower temperature of the part, which means that the use time of the equipment is increased due to lowering the temperature of the specific equipment.

Therefore, the outdoor type repeater 100 having the integrated antenna of the present invention can increase the MTTF by improving the heat of the repeater 100 as described above, which increases the use time of the repeater 100 and increases the operating cost It can be saved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims And changes may be made without departing from the spirit and scope of the invention.
