Study Of Impact From The Electromangnetic Radiation Of Various Base Station On The Environment

The thesis studies the electromagnetic radiation characteristic of base station likeGSM(Global System for Mobile communications),TD-SCDMA(Time Division-Synchronous Code Division Multiple Access),WCDMA(Wideband Code DivisionMultiple Access) and collocation. The study method is contrast analysis by theorycalculation and field monitoring. This thesis calculates the impact of electromagneticenvironment of GSM,TD-SCDMA,WCDMA base station and2G and3G collocationbase station, respectively. Electromagnetic radiation of various of base station wasmeasured by Narda EMR-300, Narda NBM55and PMM-8053A, and that of collocationbase station was measured by SRM3000. Based on the result of comparative analysis,this thesis studies the electromagnetic radiation characteristic of base station anddiscusses influence of base station parameter and its surrounding environment onelectromagnetic radiation and obtains electromagnetic radiation characteristic of variousof base station. Viewed from electromagnetic environmental protection standpoint, thisthesis comes up practical effective measures containing protective principle, protectiveobjects, protective distance. According to base station electromagnetic radiationcharacteristic and urban and rural differences, a scheme for base station site location andequipment type selection is presented in this thesis.
