The "Ruselectronics" holding, part of the Rostec Group, has started supplying "Groza" tropospheric communication stations equipped with a new digital modem using neural networks. These stations provide communication at a distance of up to 210 km, which is especially important for remote areas, and support data transfer rates up to 45.5 Mbps.
The operating technology of the "Groza" station is based on the reflection of a signal from the troposphere, the lower layer of the atmosphere. To create a connection, at least two transceiver stations are required. An antenna with a diameter of 150 cm can be installed on various platforms: from the roof of a building to mobile masts or tripods. The main feature of the solution is a digital modem that, thanks to neural networks, can adapt and extract useful signals from noise. Updating the data processing algorithms in the modem has almost doubled the data transfer rate compared to the previous version.
The production of these stations is carried out at the Krasnoyarsk NPP "Radiosvyaz" with the support of the Industrial Development Fund.
Rinat Galeev, General Director of the enterprise, noted that the "Groza" stations are designed for wireless communication in remote areas and along transport routes, offering ease of deployment, low power consumption and an economic alternative to satellite communications, which requires channel leasing.
