A study from an industry association promoting 5G claims cellular vehicle-to-everything (C-V2X) offers better vehicle-to-vehicle (V2V) connectivity than dedicated short-range communications (DSRC).
The 5G Automotive Association (5GAA) has published a study that has found C-V2X “consistently – and in many cases overwhelmingly – outperforms 802.11p/DSRC”. However, the group freely admits one of the qualifiers for this superiority was C-V2X’s greater adaptability to 5G, a technology it itself is seeking to promote. The group also said it found C-V2X performed better than DSRC in the areas of “reliability over [an] extended communications range”, “non-line-of-sight performance”, and “resiliency to interference … from other devices”.
The group noted the latter criteria would be “particularly important in … non-line-of-sight scenarios” when the limitations of connected vehicle tech can manifest themselves, but it neglected to mention that such situations can also present barriers to 5G infrastructure.
Commenting on the study, 5GAA chief technology officer Maxime Flament claimed it showed C-V2X to be “today’s most cutting-edge technology for connected and automated driving, and the best to finally deliver upon safety and traffic efficiency”. He also claimed all the group’s member organizations “believe in C-V2X as the future of mobility”.
