On 5G Radiated Field Measurement/Calculation Procedures and Exposure Compliance Limits

Abstract

The paper deals with several measurement and calculation procedures applicable in 5G New Radio technology. It brings the comparison of measured and calculated electric field levels for the purpose of simplification of industry field work. The structure of 5G New Radio signal is shortly explained, as well as all applied measurement procedures: Code-Selective Procedure, Frequency-Selective Procedure and Channel Power. The results are presented in 95% confidence interval and compared to the valid limit values. For the purpose of electric field calculation, several approximations procedures are used: Free Space, Perfect Ground Reflection and lossy ground reflection based on reflection coefficients arising from Fresnel and Modified Image Theory approach, respectively. Some illustrative results are given in the paper.
