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.

NOTE: 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.

10 Gbps 60 GHz V2N Connectivity for Your Transportation Projects

To ensure optimal performance of the MobiBridge radios, a comprehensive test was demonstrated to measure 10 Gbps 60 GHz V2N Connectivity.

ELVA-1 introduces a revolutionary approach to V2N (vehicle-to-network) high volume data transmission, leveraging robust 10Gbps MobiBridge radio technology across a whopping 10 gigabit channel. In the following demonstration video, an impressive 470GB file is seamlessly transferred from on board vehicle storage directly to its operator’s remote server in real time – highlighting exciting new possibilities for light rail transport systems, intercity buses and self driving cars when it comes to their transportation of security camera recordings, passenger films or route information alike.

The transportation industry requires data exchange between vehicles and operators to be completed in a rapid manner. This applies to light rail transport, intercity buses, autonomous cars – exchanging security camera recordings, passenger films or route details for self-driving automobiles as only some examples. To achieve the best possible transfer speed of 10 Gigabit per second it is not enough relying on radio connectivity: server hardware such as storage drives and network cards must also optimized; this can conveniently achieved through usage of Data Booster devices which compile information from cameras and sensors via standardised interfaces.

ELVA-1 provides an innovative solution for the transportation industry: Mobibridge radios, which offer fast and reliable wireless communication. Our revolutionary 60 GHz 10Gbps technology allows data to be transferred in a matter of seconds during short stops.

Latest test of E-band 70-80 GHz 10 Gigabit V2X/V2N Light Rail Connectivity

For the first time in the industry, next-generation 10 Gbps wireless communications are being tested for a light rail.

This testing of V2N (Vehicle to Network) connectivity is aimed at the development of digital ecosystems in public transport. The project is being implemented in cooperation with the light rail operator Transport Concession Company.

ELVA-1 has announced the testing of PPC-10G-Rail 10-gigabit wireless communication system operating in the 70-80 GHz (71-76 / 81-86 GHz) band is being carried out on the light rail routes. The purpose of the tests is to develop ultra-broadband communication technologies between a network and moving vehicles (V2N), analyze the characteristics of a wireless connection and its availability at various distances between the rail transport and base stations, and also to collect traffic statistics for various weather conditions.

The existing technologies for connecting rail transport to the Internet (train-to-ground) are widely based on the use of GSM modems. In some of the projects, a network of roadside Wi-Fi access points is used. Both technologies are characterized by low connection speed (up to 300 Mbps) and handshaking delays when switching from one base station to another.

Read new blog post on 10 Gigabit V2X/V2N 70-80 GHz E-Band Connectivity Car-To-Network

Read a story about how ELVA-1’s partner successfully tested 71-76/81-86 GHz E-band wireless radios for V2X / V2N communications. The technology is promising self-driving cars and driverless rail transport.

ELVA-1 reported the results of the experiment with the organization of 10-Gigabit full-duplex communication V2X (“a car for everything”) to moving car.

The experiment proves the efficiency of the idea:

  • For the frequencies 71-76 / 81-86 GHz, the practical possibility of transmitting a data stream to a moving vehicle with a bandwidth of up to 10 Gbps is shown .
  • The distance of stable communication in the experiment on the road is up to 2.5 km at a transmission rate of 2 Gbps, and in tests on a countryside road, a connection of 10 Gbps was achieved already at a distance of about 500 m between the vehicle and the base RRS.
