| Radio communication technology along with the social economy each developed for use in people’s social life, new technology, new business like bamboo shoots after a spring rain appear repeatedly, radio facilities demand rapid growth, resulting in serious environmental deterioration of the radio spectrum. The concept of grid radio monitoring appeared. The most significant monitoring mode characteristics on the monitoring data of the information as the foundation strengthen the contact in the radio administration, radio business applications, radio monitoring technology three aspects, to provide technical support and better promote the radio management level.In this paper, from the basic knowledge of grid of radio monitoring system to start, coverage determination on issues such as face in the radio monitoring system construction of grid sites for key research, the main works are as following:First, outlines for the current radio monitoring dilemma, such as wireless communications equipment gradually to the miniaturization, digitization, intelligent development, the traditional large-scale monitoring station of low radiation power monitoring capacity and distance of the shortage of spectrum utilization, a specific region with the situation is also not effective evaluation. Thus the concept of grid radio monitoring system, the basic concepts, features and functions are introduced.Secondly, in view of the main challenges that facing the construction of the grid radio monitoring system, such as the problem of monitor site location and coverage, analysis of different radio waves propagation models, and the transmission distance is calculated.Thirdly, the paper uses existing technology into field measurement and intelligent simulation software, the grid with a single monitoring site in the radio monitoring system, comparing the coverage of summing rules, for the actual construction of Xi’an in Shaanxi grid radio monitoring system to lay a certain theoretical basis. |
