Along with the LTE mobile communication network rapid demand in China, it appears more trouble and difficulties in network plan and needs a faster and relative accurate scientific method to support the BS (base station) location survey with a view to the weakness transmissibility of the radio wave above 2 GHz. The BS location survey project is one of the important items in mobile communication network plan before construction; however there are less computation model methods and theoretical arithmetic based on measured data to be utilized. The conclusion of BS location survey projection is mainly depended on the experiences and subjective judgments of survey stuffs. In considering of objective factors of surroundings parameter collection, length of work time and etc. in location survey, the common methods including propagation model, ray tracing and etc. have such difficulties and incompetence to apply. Huygens-Fresnel principle is one of most key point characters of radio wave. In the propagation of radio, every point on the surface of the wave is a secondary radiation wave of spherical wave. And space for a bit of radiation field is surrounded by the wave of each point on the arbitrary closed surface wave from the secondary waves in which the result of superposition of mutual interference Take advantage of Huygens-Fresnel principle it has greater possibility to adapt the ability range of BS location survey tools and the requirement of work time with the rapid computation method of Fresnel Zone in BS location survey project. In this paper, it is reported that Fresnel Zone method for the mobile communication will be studied in-depth and the application and the propagation criterion selection of this method will be analyzed concretely.
