Statistical Approach for Exposure Assessment to IEEE 802.11 Base Stations in Indoor Environments

The paper presents a methodology developed and implemented for the assessment of human exposure to Indoor Base Stations compliant with the IEEE 802.11 Standards. An efficient procedure that combines simulations and measurements has been introduced and verified in a selected and controlled environment. The procedure is based on a precise simulation of the electromagnetic ambience where the access points are deployed, by means of a combination of physical and ray optics. A statistical description of the obstacles is implemented to sped up the computational time. Data have been statistically analyzed and compared to measurements, to identify conservative exposure coefficients that minimize the number of measuring points, without introducing an excessive overestimate.
