The 5G Automotive Association applauds FCC adoption of C-V2X rules in the 5.9 GHz band
WASHINGTON, D.C., 21 November 2024 – The 5G Automotive Association (5GAA) welcomes the U.S. Federal Communications Commission’s adoption of 5.9 GHz band rules allowing cellular vehicle-to-everything (C-V2X) equipment to support roadway safety communications technologies.
The dedicated spectrum will support C-V2X direct communications between vehicles and roadway infrastructure, cyclists, pedestrians and other vulnerable road users. It brings to closure a process initiated by 5GAA’s first petition for a waiver to the FCC in November 2018, requesting that C-V2X direct communications be allowed to operate at 5.9 GHz.
“Today’s FCC decision will enhance roadway, cyclist and pedestrian safety by enabling highly reliable and low-latency C-V2X communications,” said John Kwant, Executive Director, Americas, for 5GAA. “Now, for the first time in the United States, C-V2X can operate freely in the 5.9 GHz dedicated transportation safety spectrum in tandem with network connectivity to provide unparalleled safety alerts for greatly enhanced vehicle efficiency and awareness of roadway threats near or far, seen and unseen.”
The C-V2X ecosystem gains a new momentum with the FCC decision providing regulatory certainty to willing deployers and fueling the upcoming US DOT National V2X Deployment Plan, which 5GAA expects to set a clear vision and milestones to achieve the vision zero goal.
As the leading C-V2X industry proponent, 5GAA looks forward to working with its members and the greater automotive ecosystem to deploy this technology across the U.S.

Sustainability
Sustainability benefits of C-V2X
Cellular Vehicle-to-Everything, or C-V2X, communications will make transportation not only safer and smarter but also more sustainable.
Sustainability has three dimensions: environmental, social and economic.
C-V2X ticks all three boxes:
- Environmental: By helping to make every trip smarter, safer and more efficient, C-V2X helps reduce congestion and accidents, thereby reducing air pollution, noise pollution and energy use.
- Social: Saving lives and avoiding injuries are clear social benefits. By enabling real-time communication between pedestrians, cyclists, traffic infrastructure and moving vehicles, including motorcycles and electric scooters, C-V2X will help avoid accidents that otherwise would result in injuries and deaths.
- Economic: By enabling more efficient mobility, C-V2X will save people and employers billions of man-hours currently wasted in traffic jams. Those man-hours can then be dedicated to more rewarding activities.
C-V2X also enables the growth of autonomous mobility, which in turn offers even greater sustainability benefits, for example mobility-as-a-service offerings.

C-V2X and Sustainability in detail
ENVIRONMENTAL BENEFITS
- Transport still represents about 25% of Europe’s total CO2 emissions. By helping to make every trip smarter, safer and more efficient, C-V2X helpsreduce congestion and accidents, thereby reducing energy use, noise pollution and air pollution.
- C-V2X can help all vehicles operate and deliver people and goods more efficiently, thereby reducing pollution and optimizing the use of valuable energy resources.
- INRIX calculated that each second of reduced delays at traffic signals across the United States would translate to an annual reduction of 800,000 metric tons of CO2.
- Connected vehicle technology can help electric cars calculate an energy-optimised route to a charging station that’s not necessarily the fastest or nearest but requires the least energy to reach.
- Examples of environmental benefits enabled by C-V2X technologies include:
- Current technology permitting smarter routing for all vehicles in both urban and rural areas, for example via automated traffic routing, road, bridge, tunnel and parking availability updates and smart parking.
- Future technology permitting “green waves” for emergency vehicles, cars, trucks, lorries and other vehicles instead of stop-and-go traffic.
- Future technology facilitating manoeuvres and cooperation in traffic.
- For more detailed information, please see TNO’s report for 5GAA on the Environmental Benefits of C-V2X.
SOCIAL BENEFITS
- By enabling real-time communication between pedestrians, cyclists, traffic infrastructure and moving vehicles, including motorcycles, C-V2X will help avoid accidents that otherwise would result in injuries and deaths.
- According to the World Health Organisation, there were 1.35 million traffic deaths globally in 2016, the latest year for which global data are available. Road traffic deaths are a leading cause of death among young people, in particular.
- In the European Union, there were about 20,608 road deaths in 2023, or about 46 road deaths per million inhabitants.
- In the United States, an estimated 40,990 people died in road accidents in 2023. The United States Department of Transportation has set an ambitious goal of zero traffic deaths, in part by leveraging advanced technologies to prevent accidents in the first place.
- It says: “The U.S. Department of Transportation’s National Roadway Safety Strategy specifies that zero is the only acceptable number of deaths and serious injuries on our roadways. USDOT is committed to taking substantial, comprehensive action to achieve this goal.”
- By providing real-time hazard notifications and enabling connected cooperative driving, C-V2X makes transportation safer for all road users, including cyclists. As C-V2X makes the roads safer, more people may feel confident in choosing cycling as their primary mode of transportation.
- A U.S. DOT pilot study demonstrated that C-V2X technology can prevent accidents and injury for vulnerable road users.
- Green waves and corridors for emergency vehicles can help save lives and reduce injuries, allowing people to lead longer, healthier and more fulfilling lives.
- Response times are critical for emergency vehicles and first responders to save lives. A 2020 study showed that “green waves” at traffic lights could reduce response times by as much as 30% with little impact on overall traffic conditions.
- By enabling more efficient mobility, C-V2X will save commuters billions of man-hours currently wasted in stressful traffic jams.Those man-hours can be dedicated to more enjoyable and rewarding activities such as doing sports, hobbies, volunteering, education or spending time with friends and family.
- In Europe, the average driver in some cities loses more than 150 hours per year stuck in traffic jams.
- Americans lost as much as 3.4 billion hours in traffic in total in 2021.
- C-V2X helps connect other modes of transport with one another to facilitate a real multi-modal transportation system.
ECONOMIC BENEFITS
- By enabling automated driving and mobility as a service, C-V2X will help create new products and services that help drive more sustainable economic growth.
- For example, anonymous data collected through C-V2X can help governments and policymakers develop more effective infrastructure maintenance programmes and traffic plans.
- By enabling more efficient mobility, C-V2X will save employers and entrepreneurs billions of man-hours currently wasted in traffic jams.Those man-hours can then be dedicated to more rewarding activities.
- For commercial vehicles, C-V2X can help optimise delivery routes and schedules and reduce the number of empty or partially loaded trips. Efficient route management reduces energy use and pollution.
- The deployment of C-V2X technologies in vehicles can increase demand for 5G and future networks, each of which will be more energy-efficient than the technologies they replace.

Meet Our Members – Interview with Menno Malta, Monotch CEO
The 5G Automotive Association (5GAA) thrives on the collective expertise and collaborative spirit of its members. Over 110 organisations strong, our membership represents a global network of market leaders and innovators shaping the future of connected mobility.
We are kicking off a new series, “Meet Our Members,” to delve deeper into the stories of the individuals who make up the backbone of 5GAA. First up, we will be featuring Menno Malta, CEO of Monotch, who has been actively involved in one of 5GAA’s most recent and exciting areas of work – Vehicle-to-Network-to-Everything (V2N2X) communication.
This interview series will showcase a diverse range of profiles, highlighting their contributions, challenges, and predictions for the exciting world of 5G-connected transportation. Get ready to be inspired by the passion and ingenuity of our members as we meet the people who make 5GAA.
Menno, you are the CEO of Monotch, a 5GAA member company. How does Monotch’s work relate to 5GAA’s, and what keeps you engaged with our association?
Monotch operates at the forefront of the V2N2X market. Our proven TLEX platform is used by cities and road authorities all over the world to connect mobility and digital infrastructure bringing substantial societal benefits and increased cost-effectiveness.
The initial interest that drew us to 5GAA was the opportunity to engage with OEMs, mobile network operators, and related industries. This is still of interest! We really appreciate the possibilities to discuss developments and work jointly on progressing the market. The networking opportunities are also great for us.
Monotch is based in the Netherlands. Last year, your views were instrumental in the organisation of 5GAA’s workshop in the Hague, where we looked at C-V2X deployment in the Low Countries. Two years later, what is the state of play for C-V2X and connected mobility in the Netherlands, and how do you see it unfolding?
In the Netherlands, we see a steady growth of smart and connected roadside infrastructure as well as new use cases such as emergency vehicle warnings that are now available on a large scale. This leads to more connected parties, including the first vehicle OEMs. On top of this, there is a push on urban challenges and use cases, which will lead to even more data and impact in the next few years. The Netherlands is truly a lighthouse deployment, and authorities from other countries come here often to see what’s happening and how they can apply learnings in their own jurisdiction.
One of 5GAA’s recent areas of work has been vehicle-to-network-to-everything (V2N2X) communications, and you’ve been one of its main contributors. What is V2N2X, what makes this such an important topic, and what are some of the biggest hurdles to overcome in achieving its widespread adoption?
V2N2X is a subset of overall V2X, where the cellular network and cloud components are used to realise connected mobility. It allows the ecosystem to get to scale with many use cases in a relatively short term, as it leverages existing technology such as apps, onboard units and, of course, the 4G/5G network! I think it’s hugely important for 5GAA as it shows the value of a connected ecosystem to the main stakeholders and can kickstart overall C-V2X deployment.
The V2N2X work item has been concluded with the publication of a white paper, ‘Road Traffic Operation in a Digital Age,’ and two associated reports. What is the objective of these publications, and how do they complement each other?
The white paper can be seen as a summary of the Technical V2N2X Architecture report. It’s a great read for everyone involved in this market, whether you’re an authority or a private sector executive. The Technical V2N2X Architecture report offers detailed insights into the blueprint architecture, and I recommend it to subject matter experts.
The other technical report is of a different nature. It describes the V2N2X market from a business perspective—for example, the market size, the kinds of business models we see, and which factors drive the market. It also contains descriptions of large-scale example deployments, taking away whatever doubts people might have about the feasibility of V2N2X..
The upcoming online session on 18 June will present the findings of these publications. What are you most excited about sharing with the audience?
So much to share! I can promise the session will be packed with insights, but I’m probably most excited to share the OEM and IOO (Infrastructure Owner and Operator) customer profiles we created. It’s about their goals, pains and gains, and for this, we did a survey and an analysis of large-scale deployments. I’m so excited about it because it really ties to the why of our work.
