It is shown that the problem of designing a secure wireless network localized in a limited area of space must be solved through joint consideration of issues on ensuring uniform distribution of the electromagnetic field level in a given local area and minimizing the spurious electromagnetic radiation beyond its limits.
The results of the electrodynamics analysis carried out within the framework of the solution of the problem are presented for the case of communication organization inside shielded premises by placing antenna elements in them on the basis of concentrated and (or) distributed radiators inside them. In this case, the shielding structures forming the walls of the shielded room were considered as ideally conductive.
Normalized distributions of electromagnetic fields are presented for various arrangements of the radiators, as well as for different frequency ranges. It is established that for some types of rooms the most significant factor affecting the field distribution is the operating frequency range.
