2022: Base Station Layout

On June 9, 2022, representatives of NRNU MEPhI announced that a mock-up of the next generation communication base station 5GS created in the engineering center on the basis of the Open project.

As reported, the layout is a two-channel base station with a radiophoton antenna module. During the creation of the layout, radio photonics technologies were used for spectral multiplexing and combining UpLink/Downlink data channels.

Scientists and engineers of the center are developing their own stack of hardware and software modules for the active antenna system O-RU of the sub-6 GHz and mm-Wave bands. In particular, it is planned to create their own IP modules in accordance with the O-RAN specification: the nFAPI data translation module, PHY, DDC/DUC, CFR/DPD modules.

Also in Russia, for the first time, fully domestic active antenna modules will be created, allowing the implementation of 5G technology . The intellectual property of the developed solutions remains completely in the Russian Federation.

The developers of the engineering center of the National Research Nuclear University MEPhI are ready to take on part of the work on the creation of domestic equipment for 5G communication systems. In particular, the specialists propose to implement modulation and demodulation algorithms, antenna systems and blocks, as well as a component base in the microwave region. In addition, the center proposed to train qualified personnel for the implementation of a large-scale state task.

The development of domestic infrastructure requires, among other things, the development of its own electronic component base IP and cores. We are ready to take on part of this work - in terms of "physics" and the creation of a component base in the microwave area - power amplifiers, low-noise amplifiers. Our center already has experience in creating base stations, GSM 3G and. 4G For June 2022, we are faced with the task of optimizing this infrastructure and moving to 5G. MEPhI also developed a 100 Gbps stream trunk line encoder, which can be used in the domestic infrastructure of cellular networks. data reported by Vladimir Klokov, head of the center

One of the first MEPhI projects implemented was associated with the construction of a prototype GSM base station based on UmTRX SDR and SW project OpenSource back in 2013. Since then, specialists have come a long way - they have developed their own equipment and by 2016 established serial deliveries of the product. Later they introduced their own physical layer stack, the L2 software stack, began to optimize its technical characteristics, switch to communication standards from GSM to 3G and 4G.

MEPhI has its own technological center for creating a component microwave base, the resource of which is involved in solving problems at each stage of product development. added chief constructor

According to Vladimir Klokov, educational projects can also come to the rescue in solving the problems of creating domestic equipment for 5G communication systems.

Since 2018, the engineering center has become an active participant in the educational process of the university. Employees combine scientific work with teaching. For June 2022, we offer three main areas for organizing personnel training for the 5G + communication system market. told Vladimir Klokov

First, scientists insist on the creation and implementation of additional educational programs - information technologies and communication systems. It is proposed to implement them within the framework of undergraduate, graduate and postgraduate studies. List of competencies of future professionals - digital signal processing, baseband infrastructure application level, encryption, circuitry and microcircuit engineering, hardware.

It is also proposed to create advanced training courses and additional educational programs in the field of telecommunications systems. Additional education, according to experts, should be introduced in such areas as: digital signal processing, encryption algorithms, hardware construction, testing and verification methods.

Thirdly, scientists propose to make NRNU MEPhI one of the leading certified centers in the field of 5G + communication systems. Here it is necessary to direct all efforts to the development of metrological support, or rather, to the development of input and output control methods for the equipment of 5G + systems. It is important to ensure access to international education markets in the field of telecommunications systems. Equally important in this direction is the development of new standards for communication systems using promising integrated photonics technologies for 6G technologies.

Work on the creation of domestic 5G equipment in Russia began in 2019. Then the Ministry of Industry and Trade presented a draft target program "Development of industrial production of fifth-generation networks and the Internet of Things in the Russian Federation for 2019-2024." It provides for the allocation of funds for the creation of equipment and software for 5G networks and the Internet of Things in Russia.
