The article presents scientific and technical proposals on the possibility of joint use of radio frequency spectrum of the fifth-generation mobile radio communication means and existing departmental radio-electronic facilities. On the basis of the load analysis, using the method of theoretical assessment of electromagnetic compatibility, the norms of territorial diversion between radio means are obtained. On the basis of the results of the calculations, it is possible to determine the subbands in which the joint use of radio means is possible, subject to optimization of the frequency-territorial plan and implementation of technical and organizational measures to ensure electromagnetic compatibility.

Radio Frequency Spectrum

Deployment of space systems based on multi-satellite constellations to provide broadband Internet access and communication services acutely raises the question of their radio frequency support including issues of electromagnetic compatibility (EMC) between competing space systems using multi-satellite constellations (StarLink, OneWeb, Kuiper, etc.), their EMC with traditional space systems (satellite communication systems that employ spacecraft in geostationary and non-geostationary orbits, space systems of other services), as well as regulatory issues of entering into service and staged deployment of space systems. The article formulates the problematic issues of radio frequency support of modern space systems taking into account the trends of satellite constellations deployment and proposes the solutions with consideration to international and national requirements in the regulation of radio frequency spectrum including the ITU requirements and the requirements of Russian State Commission for Radio Frequencies. The paper shows the ways to share the radio frequency spectrum to meet new requirements of the World Radiocommunication Conference 2019 (WRC-19).

Radio Frequency Spectrum

A technique of estimating the possibility of distribution (allocation) of frequency bands for single-frequency systems is proposed. The technique provides the valueof the radio-frequency spectrum unavailable for singlefrequency systems in the specified territorial area and frequency band according to the conditions of electromagnetic compatibility with existing radioelectronic equipment. A system of criteria for evaluating the possibility of allocating frequency bands for singlefrequency systems is proposed. Предложена методика оценки возможности распределения (выделения) полос частот для одночастотных телекоммуникационных систем. Методика предусматривает определение величины адиочастотного спектра (РЧС), недоступного для одночастотных систем в заданном территориальном районе и полосе частот по условиям электромагнитной совместимости (ЭМС) с существующими радиоэлектронными средствами (РЭС). При этом учитывается групповое помеховое воздействие радиоэлектронных средств одночастотных систем на существующие РЭС. Предложена система критериев оценки достаточности доступной части спектра для удовлетворения потребностей в этом ресурсе одночастотных систем.

This paper deals with the procedure of new transmitter insertion into the existing Plan, including results of transmitter insertion simulation with software support developed for the proposed algorithm. The same procedure can also be applied for other radio communication services using the corresponding plans and technical requirements databases (minimum field protection ratio, etc). The proposed algorithm ensures an efficient and economical use of radio frequency spectrum.

The radio frequency spectrum is a limited natural resource, which is very important and strategic in the operation of telecommunications. Considering that it is a limited natural resource, its management is regulated internationally by the International Telecommunication Union (ITU), in which details are set out in the radio regulations (RR) as an integral part of the ITU Convention. The study is based on applicable legal regulations and is supported by literature studies. The results of the study indicate that the regulation of the radio frequency spectrum is based on radio regulations, international agreements within the ITU through the World Radio communication Conference forum. The implications of regulating the use of the radio frequency spectrum always take into account the general public needs for the dynamics of the progress in telecommunications technology, of which implementation of its utilisation rests in the principle of fairness and equity between regions, and efficiency. Therefore, all policies made are directed at creating a market balance, ensuring fair competition between telecommunication operators as a potential to prevent market dominance, as well as protecting consumers.

Radio Frequency Spectrum

Data presented at this symposium showed that there had been considerable progress during the previous year towards the solution of one of the basic problems in radio astronomy—the determination of the full radio frequency spectra of the discrete sources. The generally accepted plan is to establish the spectra of a few ‘reference sources’. At present, these reference objects must be chosen from among the most intense sources, Cassiopeia A, Cygnus A, Taurus A and Virgo A. The utility of both Cygnus A and Taurus A is impaired by their close proximity to other discrete sources of appreciable strength. If they are to be observed with small antennas, meticulous interferometry, employing both variable spacing and variable azimuth, will probably be required in order to obtain an accuracy of 10 %. Cassiopeia A and Virgo A appear to be sufficiently in the clear for present needs, though only the latter is visible in both hemispheres and it is about twenty times less bright than Cassiopeia A. However, Cassiopeia A has received most attention so far. The effects of radiometer non-linearity must be examined, particularly at the lower frequencies, when calibrating Virgo A in terms of Cassiopeia A.
