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, are being 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 and it's spading ax standard, which almost twice exceeds ac in terms of the maximum transmission rate. In cellular communication networks, LTE (4G) technology is widely used, but it is already being replaced by 5G systems, which are much faster than 4G, and use radio frequencies up to several tens of gigahertz.
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. The role of unmanned aerial vehicles (UAVs) is growing rapidly. In local conflicts, the use of small-sized UAVs is of particular importance, which not only conduct reconnaissance from the air, but also act as weapons capable of effectively destroying enemy forces and assets.
One of the most effective areas of improvement of the radio monitoring methods is the use of automated systems, combining a large number of territorially dispersed technical means, 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.
