There was a time when I answered How to make self-driving cars work The idea was to design a singular technology that would allow every vehicle on the road to communicate with everything. — other vehicles, infrastructure, signs, police warnings, you name it Vehicle-to-vehicle (V2V) and vehicle-to-vehicle (V2X) communications are less common, but the federal government is keeping them alive through a similar concept, cellular vehicle-to-vehicle communications.
First, I want to bring you back right now, The Backstreet Boys released the mega-single “I Want It That Way,And Star Wars has been reintroduced for generations Phantom MenaceIt’s also the year the Federal Communications Commission set aside the 5.9 GHz band to allow cars to communicate with each other and the world.
You may remember hearing about this a lot over the last 20 years, but you haven’t heard much about it in the last few years. LiDAR and cameras currently dominate developing autonomous driving technologies, but V2V once considered critical Towards a leap to a fully autonomous driving experience.
In 2016, the National Highway Traffic Safety Administration Proposed Rule Notice All vehicles must be fitted with a dedicated short-range communication system for V2X communication. DSRC enables vehicles to communicate between vehicles and traffic elements up to 300 meters apart on a dedicated 5.9 GHz bandwidth.
But after years of holding bands for automakers and no move toward an industry-wide system, the FCC decided to give away some of its bands to Wi-Fi instead. . Arstecnica report. Although the band as a whole did not sign a contract, but. In a letter sent Monday, the National Transportation Safety Board is asking the FCC to allow it to begin testing its new C-V2X technology. C-V2X allows vehicles to communicate with each other via cellular radio protocols. rather than a dedicated short-range radio signal:
The NTSB is writing to the FCC as part of the commission’s public comment period as it considers waiving its right to require automakers to adopt C-V2X technology. Conceptually, C-V2X works in the same way as his previous V2X, direct communication between vehicles or between vehicles and infrastructure. But using cellular radio protocol instead of proprietary short-range wireless communication protocols.
The NTSB said in its letter that the FCC should grant this waiver, noting that since 1995 it has encouraged countries to adopt wireless-based collision avoidance technology. The NTSB also asked the FCC to ensure that Wi-Fi devices do not encroach on the remaining 30 MHz frequencies of Intelligent Transportation Systems.
“30 MHz is enough for basic safety functions,” said Balázs Tóth-Pintér, communications specialist at V2X company Commsignia, noting that the EU has only allocated a total of 40 MHz for V2X. Unlike the US, the deployment is in Europe. “We will see around 1 million of his V2X vehicles in Europe this year. From 2024 he expects the penetration rate to reach 10 million by around 2025,” he said of his Ars is talking to
Tóth-Pintér also said the court’s ruling only added clarity in this area, noting that Commsignia “has been working on its 30 MHz since the FCC issued its ruling nearly two years ago. DSRC and We have delivered equipment with both C-V2X, so changing the physical network layer is not a big deal, so we can go full speed ahead with the deployment,” he said.

General Motors DSRC for 2017 Cadillac CTS sedan and construction of freeway connecting to suburban Detroit to test itSuccessful implementation of V2X or C-V2X requires huge investments in infrastructure and a whole new set of standards and regulations to impact. the automotive industry across diverse markets, both in America and abroad. A new industry of programming and sensor building will emerge and every state will have to compete for contracts and federal funding to be allocated and distributed.
On the other hand, in the last four years, Trump administration NHTSA did little And it certainly wasn’t suited for fighting automakers over the rules and regulations of a whole new technological frontier.
Automakers aren’t waiting for the federal government to get it together. They used lidar, cameras, sensors, and other elements contained in individual cars to push the technology forward. In doing so, automakers turned road-sharing drivers into their products. Beta testers who don’t know and imaginary technology Product and customer first, is completely inconsistent with the goal of building safer cities for all. Also, federal inaction over the past six years has made our roads less safe than ever. When V2X technology was his hot tech to bet on in 2016, he said, for example, 37,000 Americans died in car accidents. 2021, That number was 43,000.
The NTSB petition seems like an attempt to fulfill the dream of safer streets through better technology. These people should really think about what the world looks like. Self-driving cars will never happen. Of course, we don’t need V2X or C-V2X to make our roads safer, but Solutions to reduce road deaths I just think Americans are a bit of a hassle.
