Scientists from Perm National Research Polytechnic University (PNRPU) have presented an innovative device capable of providing stable broadband access to the Network even in remote areas.
The development is a modem operating in the 2600 MHz band and supporting MIMO 4x4 technology, which allows data to be transmitted over four independent channels. The device is compatible with 4G and 5G networks, equipped with four ports for wired connection and connectors for external antennas. As Sergey Tyurin, senior lecturer at the Department of Automation and Telemechanics of PNRPU, explains:
In addition, the developed modem is compatible with 4G and 5G networks, and supports modern communication standards: Wi-Fi 6 - higher connection speed (data transfer), LTE-A Pro - an improved version of 4G mobile communication, QAM256 - an encoding method that allows you to transmit more information at a time.
The key advantage of the development is high speed: up to 4.6 Gbps at a distance of 1 km from the base station and 100 Mbps at 20 km. For comparison, most commercial modems in Russia provide a speed of 100–300 Mbps, but when moving away from the tower, it drops to 1–10 Mbps. The device also supports external antennas with signal amplification up to 27 dBm, which improves the quality of communication in difficult conditions.
The cost of the new modem is 15,000 rubles for the 4G version and 22,000 rubles for the 5G model. For example, the flagship Huawei 5G modem costs 71,500 rubles, while being inferior in speed. The development may become a solution not only for private users, but also for small businesses that depend on a stable Internet connection.
The technology has already been tested using MatLab Link Budget Analysis and Google Earth software packages, which confirmed its stability over long distances.
The use of antennas has significantly improved the power and quality of the received signal, even if the user is far from the cell tower. The calculation results showed that the device operates stably at a distance of more than 11 km from the base station.
In Russia, the problem of access to high-speed Internet remains relevant for many regions, especially in rural areas. According to a study in 2024, only 39% of households are completely satisfied with the quality of communication.
