IVA Technologies, a Russian corporation, has built a modular complex for IVA S/W underwater communications, which has no analogues in the world. Naval submariners tested the complex in the Arctic at a depth of 26 m and a length of up to 2000 meters.

The features of the IVA S/W radio complex have been accomplished by integrating radio contact with a “traditional” hydroacoustic device based on the concepts of the transmission of electromagnetic waves in tandem.
There are no technological analogues of such a solution in the world at present, according to IVA Technology.
The integrated approach makes it possible to neutralize the drawbacks of hydroacoustic systems and eliminate the existence of suspended matter, algae, thermocline and other inhomogeneities from relying on the hydrology of the delivery medium. This is particularly true while operating in an atmosphere of contaminated water, as well as in environments of extreme hydroacoustic noise, especially in coastal areas.
Sergey Chernykh, Deputy Chairman of the Board of Directors of the Haytek Company, noted that tests of the modernized mobile radio complex IVA S / W have helped us to verify its efficiency and quality under real conditions. – This is a normal wave of water when there are underwater waves, as well as variations in the temperature based on the diving depth.
The existence of such variables can have a significant effect on the final outcome, but this did not happen, and all the tests were successfully passed by the complex we created. “
How the antenna IVA S / W operates underwater
A wireless transceiver, hydroacoustic and electromagnetic antennas, contact controllers and an underwater communication headset integrated into a full-face mask are included in the IVA S / W underwater radio complex.
undercode was told by the Russian corporation IVA Technologies (part of the Haytech group of companies) about the availability of a modified version of the IVA S/W handheld underwater communications radio complex. With the involvement of combat swimmers from the special purpose naval unit of the Russian Navy (Navy), the improved radio complex has been successfully tested in the Barents Sea.
A group of divers with IVA S/W equipment succeeded in developing reliable high-definition voice contact at a distance of up to 2,000 meters and a depth of up to 26 m during the experiments. The organization explained to undercode that such metrics are a kind of record” of current processes in both Russia and the world.
The integration of hydroacoustic and electromagnetic transmission mechanisms provides barriers (algae, natural and artificial barriers) for the complex to bypass. “In our case, the implementation of the electromagnetic communication theory is to relay information using the magnetic component of an electromagnetic wave,” Sergei Chernykh told:’ Water, air, ice, stone, as you know – all these are non-magnetic substances.
The magnetic field does not see a noticeable distinction between them when going through them. Because of this property, contact can be coordinated through the media interface (air-water and vice versa), even through the ice layer, as well as across barriers – such as underwater reefs.’
