guides electromagnetic waves
Massive demand for large volumes of high-speed content has sparked interest in new methods for cost-effective solutions organization «last mile». The article discusses the reasons for signal attenuation during the propagation, compared to a free and sent by various systems of electromagnetic waves. The conclusion about the superiority guided waves over short distances, and the connection between distance and magnitude of losses in the rail system. Considered guiding system in the downstream supply network. The conclusion about the benefits and the need for further study single-rail system in the electricity network.
