Description

  The present invention relates to a radio communication system, and more particularly, to a radio communication system that automates line design and line setting of radio communication apparatuses facing each other in a radio transmission section.

  When installing a wireless communication device, it is necessary to select a transmission / reception point, a radio equipment such as an antenna, and a frequency that considers interference in order to make the communication function with the required line quality. Furthermore, in the radio network design, first, a cross-sectional view (profile diagram) of the terrain where the receiving point is seen from the transmitting point is created from the terrain map. Next, an antenna, a cable, and the like used for transmission / reception are set, and the electric field strength or radio wave attenuation at the reception point when transmitting at the used frequency is calculated. With such an operation, the required S / N or C / N is evaluated. In addition, if necessary, a temporary antenna, etc. is set up on site to actually transmit a test radio wave and measure the received electric field (electric measurement work).

  Conventionally, the above-described line design is performed in advance, and then, for example, in order to determine the line quality at the installation position of the antenna body, a work is performed such as attaching a rifle scope to the antenna body and measuring the radio field intensity. It was. That is, a radio field intensity meter that measures the radio field intensity in the center area of the rifle scope field of view is provided, and the measured radio field intensity is displayed within the rifle scope field of view. The line quality is determined based on the displayed radio wave intensity, and the antenna orientation is corrected if necessary (see, for example, Patent Document 1).

  Therefore, in the conventional circuit design, a lot of man-hours and advanced calculation techniques are required for obtaining the information on the installation area and circuit design work in the circuit design to be performed in advance. Since the direction adjustment and transmission output setting are performed using a measuring instrument, there is a problem that a skilled worker is required.
