Telecom at the main digital platform of the country
Abstract
In early June, for the second time in a four-day format at the Nizhny Novgorod Fairgrounds, the 10th Annual Digitalization of Industrial Russia (CIPR) conference took place, which has become one of the five largest business events in the country. The report on the event, in which the Ministry of Digital Development, Communications and Mass Media of the Russian Federation and major telecom operators traditionally actively participate, reflects the telecom component, the volume of which is growing year by year.

Application of optical fiber of G.654 category in TEA NEXT project
Abstract
The information about the choice of optical fiber types for use in the TransEurAsian backbone TEA NEXT communication line is presented. Different types of optical fibers of G.654 category and possibilities of their welding with fiber of other categories are considered. The paper tells about setting up the extraction of G.654.E subcategory fiber in Russia.

WIRELESS COMMUNICATION
Method of increasing the security of signalling structure in the airwaves
Abstract
The possibility of increasing the structural secrecy of communication channels in the air is considered. The method of channel security enhancement for communication systems with application of noise-immune codes is proposed. An assessment of the degree of influence of the proposed method on the efficiency of the communication system, including key characteristics of the security and secrecy of the modified communication channel, as well as an assessment of the complexity of the considered method are performed.

Methodology of frequency resource utilization in the design of railway LTE-1800 TDD standard radio communications
Abstract
When designing a digital network of technological railway radio communication based on the LTE-1800 TDD standard, as well as during frequency-territorial planning, the most relevant tasks are the use of frequency resource and ensuring electromagnetic compatibility (EMC) of the system. The paper considers the topical aspects of network construction and proposes a variant of frequency resource utilisation for railway transport taking into account EMC.
