The Russian company IVA Technologies has developed a modular underwater communication system IVA S/W, which has no analogues in the world. The complex was tested in the Arctic by Navy submariners at a depth of up to 26 m and a range of up to 2000 meters.
Russian company IVA Technologies (part of the high-Tech group of companies») announced the release of an updated version of the IVA s/W mobile radio system for underwater communications. The improved radio system was successfully tested in the Barents sea with the participation of combat swimmers of the Russian Navy's special-purpose military unit.
During the tests, a group of divers with IVA S/W devices managed to establish stable high-definition voice communication at a range of up to 2 thousand meters and at a depth of up to 26 m. Such indicators are "a kind of record", since underwater communication at a comparable range is not provided by any of the modern systems both in Russia and in the world, the company explained to CNews.
The characteristics of the IVA S / W radio complex were achieved by combining radio communication based on the principles of electromagnetic wave propagation in tandem with a" traditional " hydroacoustic installation. According to IVA Technologies, currently there are no technical analogues of such a solution in the world. The combined solution makes it possible to eliminate the disadvantages of hydroacoustic systems and avoid dependence on the hydrology of the distribution medium, the presence of suspension, algae, thermocline and other inhomogeneities. This is especially important when performing work in a polluted water environment, as well as in conditions of strong hydroacoustic noise, including in the coastal zone.
"Tests of the upgraded IVA s/W mobile radio system allowed us to check its performance and quality in real conditions," he said Sergey Chernykh, Deputy Chairman of the Board of Directors of the hi-Tech group. – Where there are undercurrents, there is a natural wave of water, as well as changes in its temperature depending on the depth of the dive. The presence of such factors can greatly affect the final result, but this did not happen, and the complex we developed successfully passed all the tests."
The IVA s/W underwater radio complex includes a digital transceiver, hydroacoustic and electromagnetic antennas, communication control controllers, and an underwater communication headset embedded in a full-face mask.
The IVA S / W radio complex is designed for voice communication and data transmission both in sea and fresh water, and across the water–air interface. The dimensions of the complex are only 500 x 500 x 100 mm with a weight of about 4 kg, so that all modules of the complex with connecting wires are placed on the scuba tank, without interfering with the movement of the diver in the water.
The IVA S/W has an 8-hour battery life. Additionally, a version of the radio complex equipped with a surface communication headset can be used to accompany a group of divers from the surface.
The combination of hydroacoustic and electromagnetic communication systems allows the complex to bypass obstacles (algae, natural and artificial barriers). "The application of the principle of electromagnetic communication in our case is to transmit information using the magnetic component of an electromagnetic wave," said Sergey Chernykh. – As you know, water, air, ice, and rock formations are all non-magnetic substances. Passing through them, the magnetic field does not see a significant difference between them. It is due to this property that it is possible to organize communication across the interface (air-water and Vice versa), including through the ice cover, as well as through obstacles – for example, underwater reefs."
The IVA S / W radio complex was developed for conducting shelf research and exploration of new mineral deposits under water, including in the Arctic basin. It can be used for monitoring the situation in coastal zones, performing repairs and maintenance of stationary underwater structures, and preventing and preventing emergencies in oil and gas production areas. In addition, it can be used for the development of underwater drones, protection of water areas, as well as the organization of voice communication in the reconnaissance group of divers, including deep-sea ones.
As Sergey Chernykh explained, the radio complex for underwater communication developed by IVA Technologies includes an electromagnetic antenna, that is, in fact, radio communication is made under water, and there are really no such devices in the world.
When asked whether the IVA S / W radio complex has competitors, Sergey Chernykh explained that the underwater radio communication system developed by IVA Technologies has no analogues, but at the same time its competitors are traditional hydroacoustic communication systems that have only a hydroacoustic antenna with all the resulting pros and cons of hydroacoustics.
"We offer a comprehensive solution that combines both types of communication, maximizing the advantages and minimizing the disadvantages of each of them in order to achieve the main goal — to ensure high — quality communication between divers and the surface, regardless of their environment," said Sergey Chernykh.
In the first version of the mobile underwater radio station, which was introduced in 2018, the IVA S/W complex provided a communication range of up to 500 m when diving to a depth of 100 m, and up to 60 m across the interface (water-ice-air).

The developers also managed to reduce the influence of the directional effect of the antennas and improve reception in all directions, as well as Refine the system for switching the reception/transmission modes in order to be able to use commercially available communication headsets.
According to the results of the tests, the personnel of the military unit and representatives of the Northern fleet command expressed their readiness to use IVA s/W communication systems, IVA Technologies said.
The direction for the development of telecommunications equipment under the IVA Technologies brand was opened in the company "Hightech" in 2016. Today, it produces product lines that include the IVA MCU video conferencing platform, IVA IP phones, the IVA s/W wireless underwater communication mobile radio complex, and the IVA CV automatic face recognition system.
IVA Technologies also develops domestic processor solutions. Already in the first quarter of 2021, the company intends to release the first samples of chips based on the IVA TPU processor architecture. It is expected that the first varieties of "systems on a chip" IVA Technologies will be used on debugging boards for embedded systems and server applications. In addition, several module implementations are being developed based on microprocessors that will be directly used in customers ' electronic devices.
The Hightech group of companies also specializes in the supply and implementation of solutions in the field of information security, telecommunications, engineering systems design and it infrastructure facilities.
The co-founders of Hitek LLC, registered on November 21, 2013, according to an extract from the unified state register of legal entities, are Adam Basiev, Yury Mesropov and Olga Ilyagueva with shares of 30% each, and Sergey Chernykh with a 10% share. The former co-founder and CEO, as well as the current Chairman of the Board of Directors of the company is Nikolay Ivenev, former assistant to the state Duma Deputy of the VI convocation (2011-2016) - member of the defense Committee.
According to " Contour.focus", the company has 124 state contracts for a total of 1 billion rubles. Its customers include Ministry of interior, Ministry of Finance, "TransTeleCom", FAS, emergency, space-rocket center "Progress", the Corporation for air traffic management in Russia, "RT-inform", the "Granatum", It is etc. At the end of 2019, the company demonstrated revenue of 1.3 billion rubles, with an increase of this indicator by 26% compared to the previous year and a net profit of 43.4 million rubles.
In June 2018 "Hatak" and the state Corporation "rostec» we have signed an agreement on strategic cooperation. The agreement provided for joint activities to develop unified communications systems, data storage systems, artificial intelligence and machine vision. Automatika concern (part of rostec) has become a production site where high-Tech developments will be implemented.
In April 2020 CNews found out that within three years, Hightech will create and launch its own enterprise-level software and hardware communication platform-a competitor to Cisco and Avaya, spending a little more than 1 billion rubles.
