Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus and method for measuring a radio wave using an unmanned aerial vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication technique, and more particularly, to an apparatus and method for measuring a radio wave of a wireless communication device.

In recent years, a great deal of radio waves have been used in real life as a wide variety of wireless communication technologies have been developed and used. In addition to 3G base stations, LTE base stations are installed in many parts of the city, and radio wave devices used by ordinary citizens such as Wi-Fi access points are becoming very diverse. As a result of the spread of wireless facilities, the use environment of radio waves becomes more complicated and the risk of radio wave usage is becoming more controversial. In order to solve these problems, there is a growing interest in the measurement of radio wave environment.

Measuring radio waves in developing and using radio equipment is very important. In order to develop a wireless system and verify that it operates as intended by users, it is essential to measure radio waves in a real environment. Regular radio wave measurements are also carried out for maintenance and repair of radio equipment used in a real environment.

However, in order to make the use of radio wave appliances effective, rooftops and steel towers of high buildings are installed and installed as high as possible. In this environment, there are many risks and difficulties in measuring the intensity of radio waves transmitted by the base stations, such as climbing high steel towers or climbing the rooftops of buildings. Also, there is a risk of safety because people have to approach the antennas where strong radio waves are transmitted by holding the instruments directly.

Radio waves for digital terrestrial broadcasting are also being transmitted nationwide. Administrative authorities and broadcasters measure the radio propagation environment around the country in order to guarantee the citizens' right to watch. In the case of TV broadcasting, there are many limitations and difficulties in order to measure the intensity of the received radio signal because the antenna must be installed at a height of 9 m from the ground. Most measurement vehicles are equipped with an an- nome master, which can be raised to a height of 9 meters, and an antenna is rotated and attached to a number of additional devices. In addition, if the antenna master moves up to 9m, there is a risk of overturning of the vehicle. Therefore, there are many restrictions on the stopping position of the vehicle, so that the measurement may not be possible at a desired place.

The present invention provides a radio wave measuring apparatus and method using an unmanned aerial vehicle in order to enable safe and accurate real-environment radio wave measurement required in the entire course of radio wave utilization such as development, installation, maintenance, and maintenance of radio facilities.

The present invention relates to a radio wave measuring apparatus using an unmanned airplane, which comprises an unmanned airplane, an antenna installed at a predetermined position of the unmanned airplane and receiving a surrounding radio wave, And a radio wave measurement processing unit for calculating the size of the radio wave upon receiving the generated radio wave and transmitting the calculated size of the radio wave to the remote controller.

As in the present invention, when measuring the radio wave intensity of a mobile communication base station or the like by using an unmanned airplane, it can be easily used in a place where people are difficult to approach, and since a person does not have to go near an antenna having strong radio wave intensity, .

Further, even in the case of digital television broadcast propagation environment measurement, it is free from restriction of the installation place of the antenna master, and since the antenna is not required to be raised to 9 m, many risk factors disappear.

In addition, since the measurement time is shortened, the working efficiency is also increased.

In addition, when the radio wave environment is measured in the air by using the drones, it may be vulnerable to breakage or fire due to exposure to large-power radio waves. In order to solve such a problem, have.
