Keywords: MIMO technology, Massive MIMO, antenna arrays configurations, directivity functions of the antennas, radio engineering systems of railway transport, 5G
Summary: The article is devoted to MIMO technologies and analysis of its use prospects in transport radio engineering systems. The state of technological railway radio communication on the Russian railways is considered. The evolution of MIMO antennas and their spectral efficiency growth is demonstrated. The review of the basic configuration options of Massive MIMO antennas and the mathematical apparatus for calculating their orientation is given. The design and principle of operation of Massive MIMO antennas is described.It is shown that the transition of technological railway radio networks to the infrastructure of 5G networks will use MIMO technology.
