Radio monitoring is the necessary component of the radio frequency spectrum management process, because even authorized use of radio-electronic means does not always guarantee achievement of the desired results due to the difficulties of considering all equipment features and potential mutual interference. Radio monitoring methods must improve following the development of its monitoring targets, to which not only the current radio electronic facilities and telecommunication systems relate, but also high frequency industrial, medical and research units, and also sources of intentional, industrial, and natural interference.

Presently we face the rapidly growing improvement of radio monitoring object: radio communication systems, radio broadcasting, television, wireless data transmission aimed at the increase of the throughput capacity, spectrum efficiency, interference protection. Quick improvement happens on the basis of using complex modulation types with code or time separation, ultrabroadband signals, adaptation to the environmental conditions, redistribution and reuse of radio frequencies, etc.

Thus, first generation of civil digital TV systems, DVB-T, have been replaced with second generation systems, DVB-T2 that ensure increase of data transmission by 30% minimum; local wireless access Wi-Fi systems of "a, b, g, n" standards are being replaced by ac standard systems with significantly higher capacity. The LTE technology having considerable advantages over its predecessor UMTS has become widely used in cellular telecommunication networks.

Radio technologies are also seen to rapidly develop in the military area. The concept of the modern warfare assumes systematic use of military units and armaments gathered into a unified information network, which in real-time scale should allow conveying reliable and full information of the situation and command orders to all participants. The key elements of a military information network include wireless telecommunication systems used at all management levels starting from a tactical link and finishing with a strategic level.

One of the most effective areas of improvement of the radio monitoring methods is in the increasingly wider use of automated systems, combining a large number of territorially dispersed technical means for monitoring, remotely controlled from the unified center. These systems allow increasing performance and radio monitoring tasks precision, eliminating routines for maintenance personnel and raising productivity.

This section covers the principles of building automated systems supplied by IRCOS, their functional capabilities and application features, and also reviews the list of technical means included in it.
