MobiBridge-10G radio in a new task-oriented booklet

ELVA-1 presented a new task-oriented booklet about MobiBridge-10G radio

This new ELVA-1 booklet is intended for mass transit operators interested in ultra-fast 10 Gbps data offload from buses, trams, trains, etc. Currently their fleet uses many surveillance cameras, digital ticket machines and other devices and this data volume is usually 300-600 GB per vehicle per working day.

The task to offload such amount of data to operator’s network requires very fast wireless technologies. We tested ELVA-1 MobiBridge-10G with 600 GB data offload, and it takes only 10 minutes to complete.  Other technologies like 5G, Wi-Fi, and popular 60 GHz 1Gbps radios may require several hours to upload such volume of data.

Our MobiBridge-10G 10 Gbps full duplex radio allows a mass transit company to operate a fleet of vehicles without any downtime due to data offload. Data offload can take place either at the depot or at other parking locations. We are currently conducting a comparative experiment, where the same file is uploaded from the same points by our MobiBridge radio and a one of the popular on the market 60 GHz 1Gbps radio. We will post the video on YouTube to support this booklet with a convincing field experiment.

This Ultra-high Speed Data Offload for Mass Transit Fleet booklet is available on the web

Pros and cons of 5G for train-to-ground communications

Industry experts expect greater use of 5G to connect trains to the ground and provide passengers with broadband Internet access as they are used to in their homes, offices or on city streets. At the same time, the proprietary Trackside Networks networks are being built by rail operators.

The big pros of 5G are that it’s to be almost free for rail operators, and passengers don’t have to spend money on paid on-board Wi-Fi (to be fair, many rail operators provide it for free). To focus on 5G, the rail company doesn’t have to do anything at all – just wait for the mobile operators to install 5G base stations along the railroad tracks. Then they can do an inexpensive upgrade of the train modems that receive the signal from cellular towers from LTE to 5G and feed that traffic to the onboard Wi-Fi network.

At the same time, there is a long list of disadvantages of 5G for train ground communications. Some of them will be extremely difficult to overcome, for example, due to the fact that the car is an all-metal structure, significantly weakening the strength of signals from 5G base stations to passengers’ gadgets. Read more about the pros and cons of 5G for train-to-ground communications on the ELVA blog.

5G train-ground diagram
You can find misleading terminology in the media about 5G “train-to-ground” communications, all to ” catch budgets” on the hype around 5G. It looks like this: marketing materials talk about a roadside 5G network, but in reality, it is a dedicated TSN network of the rail operator, which simply occupies the 5G frequency resource, most often in the 5 GHz band. Of course, this infrastructure is not a true 5G network, since passengers’ smartphones cannot connect to it, but only to special train terminals. An example: it is the TSN network of the British rail carrier FirstGroup called “Rail-5G”, built in cooperation with the developer of communications equipment Blu Wireless.

Solid state noise source for 300-GHz-band wireless communications

For testing terahertz communication receivers and other components, solid-state noise sources for up to 330 GHz were developed by ELVA-1 and available for orders

Terahertz communication is a prominent future because of its potential for applications in next generation wireless technologies. It is assumed that the restriction-free frequency spectrum above 275 GHz can be used to achieve 100 Gbps wireless communication. At the current time in the industry, communication in the 70-80 GHz band is implemented at a speed of 10 Gbps, and higher data transfer rates are realized only with channel aggregation, for example, 4x 10 Gbps. Terahertz communication by wireless links can completely replace optical cables when building urban-scale networks.

The expansion of the future communications industry will look to further 130+ GHz range for additional communication channels. Accordingly, submillimeter-wave noise source is needed to test and calibrate these components to reach to the millstone of 100 Gbit/s wireless communication which can fill in the gap between the optical and wireless links.

8 Channel Dual-band Aggregated 60 Gbps mm-Wave Link Deployed as a Backup for 200 Gbps Fiber

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.

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 on 11 km path in the Arctic Circle was revealed for the public.

ELVA disclosed availability statistics for 40Gbps E-band wireless channel commissioned in August 2019 for broadband Internet access for local residents. This installation of E-Band PPC-10G-E-HP / 2+0 radios was done by engineers jointly with customer’s specialists 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.

Th customer’s technical director said, “We are pleased with the operation of the radio channel across 11 km path over the 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 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, local site 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 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.
