Radiation analysis for co-exisiting GSM900 and UMTS900 networks

A three-dimensional model is created for a building structure to study the radiation exposure from base-station antenna operating under a coexistence of GSM900 and UMTS900. This model can be used to analyze the radiation distribution of the building structure in the frequency bands of GSM900 and UMTS900 and predict the level of field variation due to the deployment of UMTS900. Full wave electromagnetic simulation using Integral-equation based Method of Moments with higher order basis functions (HOB) is used in this simulation for acquiring higher accuracy with less computation time. Localized measurements were carried out to verify the simulation results and good agreements were shown.
