In this paper we propose a technique for a potential distance calculation for a system of detection emergency situation victims equipped with passive radio-tags. This calculation is performed for three channel models: open territories, forest and snowy field. For every model a level of a reader signal received by radio-tag is estimated as a function of distance. Basing on characteristics of state-of-art systems-on-crystal used for radio-tags building an average energy consumption is estimated with a few polling rates. An quantitative characteristics of harvested electromagnetic energy generated by reader in a far field is calculated via electric model of harvester. Our study shows that a potential distance of investigated system based on energy harvesting technology doesn’t exceed 50 meters for typical scenarios.
