The purpose of the work is to develop a plan for the use of the radio frequency resource of technological radio communication networks of JSC "Ukrzaliznytsia" with a step of the frequency grid of 12.5 kHz. Research methods - analysis of the use of radio frequency resource, analysis of the conditions of electromagnetic compatibility, analysis of the joint operation of radios with different frequency spacing, border coordination of frequency assignments, development of a draft plan for the use of radio frequency resource. An analysis of the use of frequency resources in technological radio networks at regional branches and affiliates of JSC "Ukrzaliznytsia". The basics of frequency-territorial planning of technological radio communication networks of JSC "Ukrzaliznytsia" are considered and recommendations on the allocation of frequency resources for radios with a step of the frequency grid of 12.5 kHz are developed.  Product Description popup.authors Indyk Serhii V Zhuchenko Oleksandr S Kovtun Iryna V Korolyova Nataliya A Lysechko Volodymyr P Maziashvili Artur R Sverhunova Yuliia O Trubchaninova Karyna A Shtompel Mykola A popup.nrat_date 2021-02-25 Close
