Year-round availability statistics for industry-first commercial 40 Gbps E-band wireless channel

Year-round 2019-2020 statistics for the availability of 40 Gbps 70/80 GHz radio across the Yenisei river in the Arctic Circle was revealed for the public.

DOK Ltd, ELVA’s manufacturing partner in Russia today has reported availability statistics for 40Gbps E-band wireless channel commissioned in August 2019 for Norilsk Nickel (LSE: MNOD) and broadband Internet access for local residents. This installation of E-Band PPC-10G-E-HP / 2+0 radios was done by DOK Ltd. engineers jointly with specialists of Edinstvo Ltd., a subsidiary of Norilsky Nickel, who is responsible for the telecommunications of the holding..

PPC-10G-E-HP / 2+0 radios operate in the frequency range 70/80 GHz and have two independent 10 Gigabit Ethernet channels. Two PPC-10G-E-HP / 2 + 0 radio bridges with various center frequency and cross-polarization of the signal allows getting 40 Gbps aggregate total bandwidth.

Pavel Vadov, technical director of Edinstvo Ltd., said, “We are pleased with the operation of the radio channel between the Igarka and Priluki sites across Yenisei river. The equipment meets our requirements for the availability of a communication line and has shown itself well when operated in the Arctic Circle. Now we are considering the possibility of increasing the capacity of the radio bridge by 4x more 10GE channels, using similar equipment from DOK for the 40.5-43.5 GHz Q-band spectrum.”

The actual annual availability of the aggregated channel for four transceivers shows compliance with the calculated values according to the line budget calculator. In terms of rain zones according to ITU-R PN.837-1 recommendation, Igarka with a value of 17 mm/h for 0.01% of the annual probability of rainfall is located between the rain zones C (15 mm h) and D (19 mm/h). The projected availability of the channel was confirmed experimentally, occupying an intermediate value between the calculated values for rain zones C (15 mm/h) and D (19 mm/h).

The equipment met Edinstvo operator’s requirements for the availability of a communication line and has shown itself well operated in the Arctic Circle.

The diagram shows the actual availability of the aggregated channel when operating in the adaptive radio modulation mode, with modulation schemes switching from QAM128 to BPSK. The hardware-controlled mode of adaptive modulation of the PPC-10G-E-HP / 2 + 0 radio bridges ensures the ability of the wireless communication line to maintain a connection at various rain levels by switching from QAM-128 modulation to lower types of signal coding QAM-64, QAM-32 etc. to BPSK. This increases the link budget ratio of the radio by temporarily reducing the data rate. After passing the rain front, the automation restores the nominal values ​​of the 10 Gbps throughput for each transceiver.

40 Gbps Wireless World Record for E-band Communications at a Distance of 11 km Over Yenisei River on Polar Circle

First time in the industry, commercial 40 Gbps wireless channel was deployed at unprecedented distance of 11 km (~7 miles) in Igarka city, Siberia. The channel has 72 μs latency and is built on doubled PPC-10G-E/2+0 E-band radios for Norilsk Nickel (MCX: GMKN).

DOK Ltd, ELVA’s manufacturing partner in Russia today has reported on their website about deployment of 40 Gbps radio channel across the Yenisei River as wireless backup of Norilsk Nickel’s 40GE fiber channel backhaul. This cross-country 956 km fiber backhaul was laid through Russian Arctic regions to Norilsk city. The fiber has 40 Gbps bandwidth similar to installed radiolink and is intended for the operation of the Norilsk Nickel Group enterprises, local mobile operators, and state and municipal services.

This installation of E-band radios was done by DOK Ltd engineers jointly with specialists of Edinstvo Ltd, a subsidiary of Norilsky Nickel, who is responsible for the telecommunications of the holding. This project is a significant technological achievement and it marks the world record for combining ultra-gigabit overall bandwidth of the E-band radio communications with the unprecedented distance range.

In fact, 40 Gbps wireless channel is a new technology that has a proven potential for developing telecommunications infrastructure of large businesses.

A particularly difficult section of Norilsk Nickel’s fiber backhaul is considered to be the pass of the cable at the bottom of Yenisei River. Extraordinary climate conditions of the Polar Circle make it impossible to repair the fiber cable under the iced waters for much of the year. In this regard, Edinstvo Ltd has decided to build a backup wireless channel with a capacity of 40 Gbps over the Yenisei River.

The points of deployment of 40 Gbps wireless channel were done at antenna masts in Igarka and Priluki cities, located on different banks of the Yenisei river at a distance of 11 km. There were used two paired radio bridges of the PPC-10G-E-HP / 2+0 model. These are four parallel independent 10 Gbps radio channels aggregated into total capacity of 40 Gbps. Such scheme provides increased reliability of the wireless channel, as each 10 Gbps transceiver has an independent connection to power supply and external network equipment.

Max latency measured at 11 km distance was 72 microseconds. These numbers show that E-band radios can bring the data capacity and latency needs of 5G networks as well.

Pavel Vadov, Technical Director of Edinstvo Ltd, said, “We have studied the product lines of Russian and global brands of 10GE radio links looking for equipment which could work at wireless distance of 11 km. Only PPC-10G-E-HP radio presented by DOK has satisfied us. After few months of testing of one pilot 10 Gbps radio, we were assured that this radiolink is what we exactly need. At the present time, the radio channel with up to 40 Gbps capacity has been put into commercial operation”.

With this project, it was confirmed that 70/80 GHz E-band 10GE radio links could be successfully used for replacement or as a backup for any hi-end fiber backhaul. There are many territories in the world  where the laying of fiber optic links is complicated and costs a lot of money. As an alternative to fiber or as a backup line, the 70/80 GHz PPC radios provide short deployment time at an affordable cost.

PPC-10G-E-HP / 2+0 operates in the frequency range 70/80 GHz and has two independent 10 Gigabit Ethernet channels. Two PPC-10G-E-HP / 2 + 0 radio bridges with various center frequency and cross-polarization of the signal allows to get 40 Gbps aggregate total bandwidth.
