The automotive industry is moving beyond traditional connected-car features toward vehicles that can communicate continuously with networks, infrastructure, other vehicles, and cloud-based systems. At the center of this transformation is 5G technology, which provides the high bandwidth, lower latency, and connectivity capabilities needed for increasingly software-defined vehicles.
Audi and Verizon have explored this opportunity through advanced private 5G networks, edge computing, Cellular Vehicle-to-Everything (C-V2X), and connected-vehicle testing. Their work demonstrates how telecommunications and automotive technology can come together to create smarter and more responsive transportation systems.
What Is 5G Technology in Cars?
5G technology in cars refers to the use of next-generation cellular connectivity to connect vehicles with digital services, cloud platforms, road infrastructure, other vehicles, and potentially pedestrians.
Unlike traditional in-car internet connectivity, automotive 5G can support applications where rapid communication and continuous data exchange are important. These include connected safety systems, real-time traffic information, vehicle diagnostics, infotainment, fleet management, and future autonomous-driving applications.
5G is not expected to make a vehicle autonomous by itself. Instead, it can provide an important communication layer that works alongside cameras, radar, lidar, onboard computing, artificial intelligence, GPS, and other vehicle technologies.
Audi and Verizon’s 5G Automotive Innovation
Audi and Verizon have worked on a private wireless network and technology-testing environment for Audi’s automotive test facilities in Germany.
The environment combines 5G and LTE connectivity, private multi-access edge computing, C-V2X communication, and real-time video and data transmission. It is designed to help Audi test connected-car technologies under different network conditions before technologies are deployed more broadly.
The testing environment can simulate connectivity conditions across different geographic regions and network configurations. This is particularly valuable for a global automotive manufacturer because connected vehicle functions need to work reliably across different markets and infrastructure environments.
Why 5G Matters for Connected Cars
Modern vehicles generate and consume enormous amounts of data. Cameras, radar, infotainment systems, navigation platforms, vehicle sensors, telematics systems, and driver-assistance technologies can all contribute to this data flow.
5G can help support automotive applications through several capabilities:
1. Lower Latency
Some connected-vehicle applications require information to move quickly between vehicles, infrastructure, and computing systems.
Lower network latency can help reduce the time required to exchange information, particularly when combined with edge computing.
2. Higher Data Capacity
Connected vehicles increasingly depend on data-intensive services such as high-definition mapping, software updates, video, cloud applications, diagnostics, and advanced driver-assistance systems.
5G provides greater network capacity that can support these growing requirements.
3. More Reliable Connectivity
Vehicles are constantly moving between locations and network environments. Automotive connectivity therefore requires network technologies that can maintain dependable communication while vehicles are in motion.
4. Support for Edge Computing
Rather than sending every piece of data to a distant cloud data center, edge computing can process selected information closer to where it is generated.
This can reduce the distance data has to travel and can support faster responses for certain connected-vehicle applications. Verizon describes mobile edge computing as an important component of its connected and autonomous vehicle strategy.
The Role of C-V2X in 5G Cars
One of the most important technologies associated with connected vehicles is Cellular Vehicle-to-Everything (C-V2X).
C-V2X allows vehicles to exchange information with different parts of the transportation ecosystem.
Vehicle-to-Vehicle (V2V)
Vehicles can exchange information with nearby connected vehicles. This could support warnings about hazards, sudden braking, traffic conditions, or other road events.
Vehicle-to-Infrastructure (V2I)
Vehicles can communicate with infrastructure such as traffic signals and intelligent transportation systems.
This can help support applications related to traffic management, road conditions, and intersection safety.
Vehicle-to-Pedestrian (V2P)
Connected systems can potentially help identify and communicate information about vulnerable road users, including pedestrians.
Vehicle-to-Network (V2N)
Vehicles can communicate through cellular networks with cloud services and other connected applications for analytics, fleet management, software services, and more.
Verizon’s current automotive work includes V2X applications designed to exchange information between connected vehicles, road users, and infrastructure.
5G and Road Safety
One of the strongest potential applications of connected-car technology is improving road awareness.
Imagine a vehicle approaching an intersection where the driver’s view is blocked. A connected system could potentially receive information about another vehicle, road hazard, traffic signal, or vulnerable road user before the driver or vehicle sensors can directly observe it.
This does not mean 5G replaces vehicle safety sensors. Instead, connectivity can provide another source of information that complements onboard sensing and driver-assistance technologies.
Verizon’s automotive initiatives include testing 5G-connected cameras, C-V2X communications, and edge computing for applications involving vehicle and infrastructure awareness.
5G, Edge Computing and Autonomous Driving
Autonomous vehicles require a combination of technologies rather than a single connectivity solution.
An autonomous vehicle may use:
- Cameras
- Radar
- Lidar
- GPS and high-precision positioning
- Artificial intelligence
- Onboard processors
- Digital maps
- Vehicle sensors
- V2X communications
- Cloud and edge computing
5G can act as a communication layer connecting the vehicle to external systems, while edge computing can provide nearby processing capabilities.
This architecture could become increasingly important as vehicles exchange larger quantities of information with smart roads, traffic systems, cloud platforms, and other vehicles.
However, autonomous-driving decisions that require immediate responses will continue to depend heavily on computing and sensing capabilities inside the vehicle. 5G should therefore be viewed as an important supporting technology rather than the sole foundation of autonomous driving.
Audi’s Private 5G Test Environment
One of the notable aspects of the Audi-Verizon collaboration is the use of a private wireless network for automotive testing.
Audi’s test environment incorporates technologies from several technology providers, including Nokia’s modular private wireless platform, AWS-based private edge computing, C-V2X capabilities, and real-time video and data transmission technologies.
The setup allows automotive technologies to be tested under controlled conditions while reproducing different network environments.
This can help automotive companies evaluate:
- Vehicle-to-cloud communication
- Connected infotainment
- C-V2X applications
- Autonomous mobility technologies
- Safety applications
- Real-time video
- Data management
- Connectivity performance
The approach can also reduce the time and complexity involved in testing connected technologies across different network environments.
5G Is Expanding Beyond Infotainment
Early connected-car discussions often focused on Wi-Fi hotspots, navigation, streaming, and entertainment.
The role of connectivity is now becoming much broader.
Modern connected vehicles can use network connectivity for:
Over-the-air updates: Manufacturers can deliver software improvements and feature updates without requiring every update to be installed manually at a dealership.
Vehicle diagnostics: Connected systems can transmit vehicle information to manufacturers and service providers.
Fleet management: Commercial operators can monitor vehicle locations, performance, and operational data.
Smart traffic systems: Connected vehicles can exchange information with transportation infrastructure.
Safety alerts: Vehicles can receive information about changing road conditions and potential hazards.
Digital services: Drivers and passengers can access increasingly sophisticated cloud-based services from inside the vehicle.
Verizon’s Broader Connected-Vehicle Strategy
The Audi collaboration is part of a broader push toward connected transportation.
Verizon’s current automotive platform includes technologies for connected vehicles, autonomous vehicles, edge transportation, location services, digital experiences, and security.
