EXPERIENCE OF PARTICIPATION IN WORLD RADIOCOMMUNICATION CONFERENCES
A.B. Nalbandian, advisor to the minister of transport, communication and IT of Armenia, vice-chairman of ITU-R Radiocommunication advisory group, chairman of RCC Working Group on preparation for WRC-19; albert.nalbandian@mail.ru
The results of World Radiocommunication Conferences (WRC) on which the Radio Regulations are constantly being improved are shown. Features of the preparation (at national, regional, global levels) and ITU Member-State participation in the WRC are analyzed. WRC is not an ordinary conference with listening of reports and possible acceptance of the streamline document therefore it is offered to consider radiocommunication conferences as multilateral, multisubject, multistage, multilingual and multi-hour negotiations. Therefore, delegates should be prepared for such negotiations. The author presents his position on the basis of his work in International Consultative Committee on Radio/ITU-R from 1977 to the present day.
Keywords: World Radiocommunication Conferences, International Consultative Committee on Radio (CCIR), International Telecommunication Union, Radio Regulations, negotiations, frequency bands, radiocommunication, radiocommunication service.

The method of organization of communication network for emergency services by using of unmanned aerial vehicles (UAV), which are used as a transport for heterogeneous gateways, is provided. Possible scenarios for the implementation of the flying network are considered, the analytical model is developed, and computer experiments have been carried out to research the parameters of the network functioning under various parameters, such as UAV flight speed, radio coverage radius and the interaction architecture of sensor nodes with
the coordinator.

The IEEE 802.11ah communication protocol suitable for the utilization in centralized networks with high number of autonomous nodes (up to 6000) and wide coverage (up to 1 km) is considered. Traffic produced by sensors in such network is commonly unsaturated because of low intensity of input packet stream per node. It creates problems in the analysis of probabilistic-time characteristics because of computation-intensive simulation. The review of IEEE 802.11ah technology’s main components is presented. The analytical model based on Markov network allowing to research system throughput and energy consumption under the conditions of high number of devices and low intensity of input stream is proposed. The developed system can be applied for planning of metropolitan area wireless networks for collecting information in such applications as industry monitoring systems, intellectual transport systems and Internet of Things.
Keywords: IEEE 802.11ah, Internet of Things, wireless networks, review, analytical model.
PERSPECTIVES OF LOCAL TELEPHONE NETWORKS OF THE RUSSIAN FEDERATION
S.P. Efimov, Association of Telephone Operators, general director, Ph.D.; a.o.t.s@ya.ru
Within the framework of new strategy of development of digital economy, adopted in the Russian Federation in 2017, the situation in communication industry and changes of revenues of fixed and mobile communication operators are analyzed. It is established that since 2012 there is a redistribution of income in favor of the largest operators with the participation of the state
budget system of the Russian Federation. Present tariff policy and existing economic models of interaction between telecom operators can lead to the collapse of communication industry and absorption of operators by transnational corporations. Some measures for stabilization of the situation are proposed. The necessity of elaborating a new plan of development of communication industry on the basis of the new concept is proved.
Keywords: telecommunications, hierarchical structure of telephone networks, telecom operators, economics of telecom operators, telecommunication monopolies, small and middle-size telecommunication enterprises.
