Fastest in the industry dual-band 8-channel (4x 10 Gbps E-band plus 4x 5 Gbps Q-band) industry-record wireless connection with aggregated 60 Gbps throughput operates on a distance of 11 km (6.8 miles).
ELVA has announced the installation of mm-wave 4x 5 Gbps Q-band (40.5-43.5 GHz) radio links as an upgrade to the previously installed four 70/80 GHz 10 Gbps radios in the Arctic Circle. All the wireless radios are being deployed at the same telecom towers at an 11 km distance above the river.
The customer is responsible for the telecommunication services of the holding, has recently expanded its fibre backbone to 200 Gbps and increased its wireless mm-wave backup up to 60 Gbps aggregated throughput.
Two independent dual-radio Q-band (40.5-43.5 GHz) wireless links (PPC-10G-Q-3ft/2+0) were used to upgrade the link. Each channel in the PPC-10G-Q-3ft/2+0 wireless bridge provides 5 Gbps full-duplex capacity, with a total capacity of the Q-band throughput equal to 20 Gbps (4x 5 Gbps), with its own transceiver, cables and power supply. A pair of radios work in different polarization, sharing a single 3ft antenna via diplexer.
This is currently the first in the industry deployment of polarity- and frequency-separated aggregated Q-band link with such capacity. Wireless radios are using 3ft antennas, which is a rare case for Q-band, so additional adjustable struts were used to sustain additional wind load.
The customer’s network team has solved the difficult task of improving the fiber line reliability at its most complicated stage, the underwater crossing of Yenisei River near the city of Igarka (Krasnoyarsk region). During the winter season of 2020-2021, a unique project of horizontal directional drilling in permafrost under the Enisei river bed has been completed before the seasonal ice drift, by drilling simultaneously from both left and right banks of the river.
The unique dual-band combination of 8 multigigabit radios working together at E-band and Q-band allows significantly improve wireless connection availability under precipitation of different types and densities.
