Worst-case estimation of electromagnetic background created by cellular mobile stations near ground surface

The novel technique of worst-case estimation of near-ground electromagnetic background created by mobile stations (MS) of cellular communications is offered. This technique takes into consideration peculiarities of radio wave propagation on different distances between MS and observation point (OP) and of statistical features of ensemble of MS signals in OP related to the presence of prevaling component. It allow to estimate the fundamental upper bound of electromagnetic background total intensity created by MS directly on the basis of calculation of the total electromagnetic loading on territory as the total equivalent isotropic radiated power of MS set falling to the unit of the area of considered territory, and/or estimation of average terrestrial density of cellular traffic intensity. The given results ensure the facilities of EMC design of cognitive radio systems in frequency bands assigned for mobile communications and of support of the acceptable electromagnetic environmental conditions in populous areas.
