60 Gbps Broadband Wireless World Record mm-Wave Links Deployed on 11 km path as a Backup for 200 Gbps Fiber

Dual-band 8-channel (4x 10 Gbps E-band plus 4x 5 Gbps Q-band) industry-record wireless connection works on a distance of 11 km (6.8 miles) from the same footprints.

The company has announced the installation of mm-wave 4x 5 Gbps Q-band (40.5-43.5 GHz) radio links in addition to the previously installed four 70/80 GHz 10 Gbps radios across a river in the Arctic region. All radios are mounted on towers at a distance of 11 km on the bank of the river.

The customer is responsible for the telecommunication services of the holding, has recently expanded its fiber backbone to Norilsk city to 200 Gbps and increased its wireless mm-wave backup over Enisei River up to 60 Gbps aggregated throughput.

Q-band (40.5-43.5 GHz) wireless link PPC-10G-Q-3ft/2+0 (2x5 Gbps)with 3ft antenna

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 cuetomer’s team has solved the difficult task of improving the fiber line reliability at its most complicated stage, the underwater crossing of the river. During the winter season of 2020-2021, a unique project of horizontal directional drilling in permafrost under the 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 8x multigigabit radios working together at E-band and Q-band allows significantly improve wireless connection availability under precipitation of different types and densities.
