C-V2X better than DSRC, telecoms study claims

Two years of real-world cellular connectivity has proved C-V2X technology is the way forward for the connected car, a mobile telecoms network lobby group has claimed, reports Paul Myles.

Naturally, it’s hardly surprising that top of its claims is that C-V2X is “superior” to DSRC that several automakers prefer as a more robust connectivity solution than cellular which still suffers from patchy coverage in many rural and even heavily urban environments.

Nonetheless, the Next Generation Mobile Networks Next (NGMN) alliance has published the results of data from more than 30 million vehicles in a white paper promoting the benefits of cellular solutions. Its findings are the result of two years of work by a task force of ‘best in class’ industry specialists from across the globe.

Key conclusions from the NGMN claim:

  • C-V2X technology is superior to DSRC/IEEE 802.11p standards from a technical, economical and eco-system perspective and can easily satisfy basic yet critical safety applications;
  • Its technical advantages include communication range, latency and scalability;
  • It has a natural evolution path to future advanced applications by updating current networks to 5G;
  • It not only covers safety features for vehicles but also supports use cases for other traffic participants, such as pedestrians and cyclists;
  • Tests are already ongoing, and the technology can be deployed by 2020.

Huang Yuhong, deputy general manager, China Mobile Research Institute. “This white paper can provide the framework for a smooth transition into the world of the truly connected car, especially as we start to see the introduction of 5G, and I strongly encourage all stakeholders involved in the eco-system to read the document and shape their future planning around it.”

The alliance hopes the commercial objectives of the project will include a reduced time to market of C-V2X and greater co-operation with the automotive industry. The paper covers various deployment aspects of the connected car, including multi-operators and roaming, business models of operating an intelligent transport system (ITS), examining available spectrum and regulatory aspects and reviewing security and privacy issues.

Yuhong stressed that NGMN supports the go-to-market statements from major industry stakeholders such as car manufacturers and chip-set suppliers. It also collaborates with other industry associations including 3GPP, ETSI and 5GAA.
