Environmental safety of cellular networks taking into consideration electromagnetic background produced by systems of public information service

The paper discusses the system analysis technique and evaluates the contribution made by the electromagnetic (EM) background, generated by cellular phones of other users, by systems of on-air radio broadcasting and diversified radio-tail objects in deterioration of environmental safety of cellular radio networks, as well as the influence of wide spreading of cellular radio communication facilities on a growing environmental risk of positioning on territories of contemporary cities of power transmitting centres and other-type radio-tail objects having power electromagnetic radiation and creating intensive EM background in densely populated places.
