PPC 20 G 2+0 is the trunk radio relay station with a transmission rate of 20 Gbps for 4G+/5G.
On June 28, 2017 the DOK company declared the superiority in creation of the trunk radio relay station on the speed of 20 Gbps for infrastructure 4G+/5G, the ISP applications and television of Ultra HD TV, in Russia. As a part of technology two standard radio bridges of PPC-10G 10 Gbps united in a set 2+0 by means of the adapter of dual polarization are used. It allowed to tell a double data stream of 20 Gbps using one antenna.
Feature of the radio bridge - independent work of each of two channels PPC-10G 10 Gigabit Ethernet. Failure of one of channels will not influence work of another. It allows to operate failsafe solutions of 20 Gbps 2+0 for wireless trunks between base stations of cellular communication 4G+/5G, to provide broadband access to the Internet and transfer of digital TV to HD/UHD quality for consumers in residential arrays, cottage settlements and industrial zones in the absence of communication on the optical cable.
The radio bridge of 20 Gbps 2+0 works in the range of 71-76 / 81-86 GHz and provides a stable relation at a distance to 6 km. In need of accumulation of capacity, radio bridges of 20 Gbps 2+0 can be aggregated with the same device in quadruple channel 4x 10 Gigabit Ethernet with the subsequent assembly in channel 40 GE by means of the network switch.
To stations of 20 Gbps 2+0 (2x PPC-10G) applies technology of millimeter waves which allows to exclude radio-frequency noises between the neighboring radio lines using the engineering device called the adapter of dual polarization (Dual Polarised Adaptor). At the same time (V) and horizontal (H) polarization of a radio-frequency signal is used vertical.
 | This very compact and high-performance communication equipment at the level of the best world analogs. At the same time, our radio bridge with the adapter of dual polarization is developed taking into account severe Russian conditions, and is capable to work steadily both in the southern regions, and in the region of the Far North with temperatures up to-50 Pages.
