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

Worst-case estimation of electromagnetic background near ground surface created by heterogeneous radioelectronic environment

“…For this group the total EMF intensity created in OP by transmitters of k-th type can be divided on following components [6]: a) EMF generated by the nearest transmitter of k-th type allocated in the "breakpoint" vicinity of OP; intensity П k of this EMF in OP is random and essentially prevailing over the EMF intensity created by other transmitters of this type allocated in an OP vicinity of radius R BPk .…”

“…EML on territory L T created by EMR of terrestrially distributed transmitters with the average EIRP P e and average terrestrial density ρ, is defined in [5,6] as follows:…”

“…EML is the integrated system characteristic defining electromagnetic safety of radioelectronic environment (REE) formed by the full set of radio transmitters allocated on the territory, for operating of radio systems and for people health. Results of [5,6] allow to estimate the fundamental upper bound of EMB total intensity created by homogeneous narrowband REE formed by the set of terrestrially distributed uniform transmitters with undirected EMR, on the basis of calculation of the total EML in the vicinity of OP. But these results are inapplicable directly for complex heterogeneous REE formed by the set of STR (with undirected and directed EMR) and MTR of different radio services and frequency bands, randomly distributed in OP vicinity.…”

“…In [5,6] the concept of an electromagnetic loading (EML) on territory as the total equivalent isotropic radiated power (EIRP) of transmitters set falling to the unit of the area of considered territory, is introduced. EML is the integrated system characteristic defining electromagnetic safety of radioelectronic environment (REE) formed by the full set of radio transmitters allocated on the territory, for operating of radio systems and for people health.…”

“…The aim of this paper is to propose on the base of [5,6] the novel applied method of worst-case estimation of the nearground EMB total intensity created by the full set of STR and MTR of different types, frequency bands and radio services, distributed in the vicinity of OP, acceptable for EMC diagnostics and design of UWB and cognitive radio systems, and for proximate analysis of electromagnetic environmental conditions in populous areas.…”
