And duplicate description thereof will be omitted.

Preferred embodiments of the present invention are largely divided into three. First, when the location is specified using the correspondence to the preset position in the order in which the radio wave environment data is stored without storing the location information separately. Second, the data and the location information are generated by generating the location information when the radio wave environment data is stored. In the case where the position is specified by the correspondence, third, the measurement position coordinate corresponding to the propagation environment data may be specified using the pre-stored reference GPS coordinates. Each case will be described below.

2A is a block diagram of a system for measuring radio wave environment data according to a first preferred embodiment of the present invention. 2A, a radio wave data receiver 210, a button input unit 220, a storage unit 230, and an output unit 240 are illustrated.

The radio wave data receiving unit 210 receives radio wave environment data as a separate RF antenna or a mobile communication terminal. When the radio wave data receiving unit 210 is a mobile communication terminal, radio wave environment data is stored in the storage unit 230 through an interface connecting the mobile communication terminal and the storage unit 230.

The button input unit 220 includes a button which is clicked to specify a position at a position at which an arbitrarily set radio wave environment is to be measured, and detects a button click signal when the radio wave environment measurer clicks a button. Since the button click signal is a signal for storing the received radio wave environment data, when the button is clicked by the button input unit 220, the radio wave environment data received by the radio wave data receiver 210 is stored in the storage unit 230. Therefore, since the radio wave environment data is stored in the order of a preset position in the storage unit 230 along the movement path of the radio wave environment measurer, the radio wave environment measurer may analyze the radio wave environment along the movement path using the stored data.

The output unit 240 outputs radio wave environment data at the time of measurement so that the radio wave environment measurer can recognize the radio wave environment, and also outputs radio wave environment data and the analysis result thereof so that analysis can be performed in various ways. do. Therefore, the output unit 240 may output the measurement position of the radio wave environment and the analysis result of the radio wave environment data. The output unit 240 may be a plan view or a grid window, the preset measurement position may be shown by a number in the plan or grid window. Therefore, when the displayed number is clicked, corresponding propagation environment data is output so that the analyst can analyze the propagation environment based on this. In addition, in the case of measuring and analyzing the radio wave environment inside the building, when the radio wave environment is clicked, the measured radio wave environment data is output as a two-dimensional planar graph or a three-dimensional three-dimensional graph. Can be analyzed. Here, the measurement position shown in the plan view or the grid window is configured as a touch screen panel so that the user can click the corresponding position on the screen to analyze the propagation environment.

According to another embodiment, the apparatus for measuring the radio wave environment further includes a device for receiving a GPS signal to obtain location information therefrom at a location where the GPS signal can be received, and at a location such as a building that cannot receive the signal. You can get location information by clicking location specific button. That is, when the button signal is detected when the GPS signal is received in the device receiving the GPS signal, the GPS signal may be specified as the measurement position information. Using this, it is possible to more conveniently specify the position for measuring the radio wave environment by using the GPS and the position specifying button according to the present invention provided in the prior art for convenience.

2B is a block diagram of a system for measuring propagation environment data according to a second preferred embodiment of the present invention. The differences from the first embodiment described above will be mainly described.

The location information generator 225 generates corresponding location information as a number when the button input signal is detected by the button input unit 220. Numbers indicating the location information are sequentially generated corresponding to the numbers of the preset location information. For example, when the radio environment measurer presses the number, if the previously generated and stored number is '4', the radio environment measurer searches for it and generates and stores the new number '5'. In addition, the radio wave environment measurer may modify the generated number when the corresponding number is missing while referring to the drawings and the location information displayed on the output unit 240. In this case, the radio wave environment measurer may modify location information generated in advance by using the button input unit 220 or directly input location information. To this end, the button input unit 220 may include a plurality of direction buttons, numbers, and letter buttons to correct and input location information.

2C is a block diagram of a system for measuring radio wave environment data according to a third exemplary embodiment of the present invention. The differences from the above-described second embodiment will be mainly described.

The GPS receiver 250 measures the reference GPS coordinates specifying the measurement position coordinates. Here, the reference GPS coordinates are coordinates for specifying the coordinates inside the building in which the GPS signals are not received, and are composed of at least three coordinates. If the reference GPS coordinates are three, the GS coordinates for any position in the building may be specified using the ratio. For example, if the reference GPS coordinates are P1 (2,3), P2 (10,3), P3 (5,10) in the Cartesian coordinate system, and the positions are indicated on the schematic, the measurement that the radio environment measurer is trying to measure. The coordinates of the position can be easily obtained by the ratio of the coordinates described above to the schematic. Therefore, the measurement position coordinate calculator 255 may calculate the GPS coordinates of the preset measurement position using the reference position, the measurement position, and the reference PS coordinate on the design drawing.

In addition, the calculated GPS coordinates may be stored in accordance with the coordinate system received by the GPS receiver to have the same effect as the GPS signal is received even at the position where the GPS signal is not received. In addition, by specifying the location of each floor of the building by storing the altitude information on the design drawings, the GPS coordinates for the up, down, left and right can be generated and stored.
