Self driving cars already have a feature of see and think for themselves. But a new technology that will run on the soon-to-be-launched 5G network promises to give them a more advanced skill, the ability to talk with each other. The C-V2X, a communication technology using the same 5G network that comes on our phones, will allow vehicles to improve both functionality and safety with traffic signals and other roadside gears with each other.
Cars will not broadcast their location, speed and direction right now – some already do with today’s 4G networks. They will be able to interact to turn on stop signals or merge into lanes, the digital equivalent of human drivers who make eye contact. By chatting with a traffic signal, your car will be able to synchronize a journey with a green light. Vehicles could also talk among themselves to squeeze more cars on the road and build vehicles to improve fuel economy.
Technology should initially help traditionally powered cars – for example, warning you of collision risks or icy paths. Advocates say that it will truly shine by making autonomous vehicles more efficient and thus more practical. Smarter self-driving cars will be able to decide what to do on their own rather than slowing a person back to control or avoid problems.
“Adding additional meaning will unlock the full potential of self-driving technology,” said Maxime Flument, chief technology officer of the C-V2X5G Automotive Association.
The C-V2X is designed to overtake a two-decade-old effort called Dedicated Short-Range Communications (DSRC), which only achieved scattered success. V2X refers to vehicles that are communicating with everything – from vehicle to vehicle (V2V), vehicle to infrastructure (V2I) or vehicle to pedestrian (V2P). C means that communication takes place on the same cellular network technology that our phones use.

Increasing C-V2X Alliance
The 5GAA, a consortium backing C-V2X, had eight founding members when it debuted in 2017. It now has 120 members, Flomart said, including key players that include several industries.
Carmakers are members including Audi, BMW, Daimler, Ford Motor, GM, Honda, Hyundai, Nissan, Volkswagen and Volvo. So are technology companies like Intel, Samsung and Qualcomm; Auto electronics companies such as Alpine, Continental and Bosch; Network equipment manufacturers including Nokia and Ericsson; And carriers AT&T, T-Mobile, Verizon and Vodafone.
The C-V2X already works on today’s 4G networks. 3GPP, is an industry group that develops wireless network standards, has incorporated some C-V2X technology that allows cars to transmit basic driving information over 4G networks. Release 15 of 3GPP, an update to the 5G standard expected later this year, will support the download of videos and maps for cars, said Nokia’s head of V2X work, Uwe Puetschler.
Putzschler said that 16, released by mid-2020, would enable more radical C-V2X capabilities, such as letting multiple cars negotiate the best way to cross an intersection. This will require a faster response to 5G, known in the industry as low latency. Release 16 should be at least 10 milliseconds less than ten milliseconds, he said. The flare is also needed to integrate cars or trucks into a platoon.

Ford is among the companies that have already reached that conclusion. In 2022, Ford vehicles will get the C-V2X, making the carmaker one of the standard’s fastest advocates. After heavy DSRC investment, Ford described the C-V2X as faster, more reliable, and less expensive, according to Jovan Zagajack, manager of Ford’s connected vehicle platform and product team.
