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.
