The Krasnoyarsk enterprise Rostel, which is part of Rostec, presented the Groza-1.5 tropospheric communication station. The devices use signal reflection from the troposphere and are designed for communication in remote regions. The station is ideal for operation in the mountains, along the coasts, and in the Far North.
Recent tests in Yamal demonstrated that the Groza-1.5 can withstand temperatures down to -50°C and provides impressive communication speeds.
During tests on a route over 63 km long, the system provided a data transfer rate of 49.9 Mbit/s. This is a record figure for tropospheric communication.
The tropospheric communication system is planned to be used in remote fields in the Arctic, where traditional communication methods are either impossible or too expensive. Unlike satellite internet, tropospheric communication does not require renting a spacecraft; only two stations are needed.
Inside the Groza is a high-speed modem with a neural network, allowing the system to adapt and extract useful signal from noise.
