Analysis of Indoor RF-Field Distribution

With the increasing use of wireless technologies great social concern has risen about health effects that might be caused by the interaction of electromagnetic waves with the human body. The compliance of exposure situations with international safety limits requires reliable methods capable of quantifying the RF field in every environmental scenario. This project focuses on the assessment of indoor field distributions caused by either indoor or outdoor base stations: We report on our semi-automated measurement method for high-resolution mapping of synthesized inhomogeneous field distributions in a semi-anechoic chamber. In addition we describe the numerical calculations of the field distributions using the finite difference time-domain (FDTD) method. The results gained by these complementary approaches will be well suited for developing recommendations for indoor exposure measurement techniques for public, national and international authorities.
