A new report from 5G America identifies a wide range of telecommunications provider-connected car opportunities, including cellular connectivity and multi-access edge computing to support intelligent transportation systems designed to make roadways safer and more efficient. (MEC) is included.
The 32-page report, titled “Vehicle Connectivity: C-V2X and 5G”, also serves as an excellent tutorial about C-V2X technology, the set of connected car standards around which The industry seems to be connecting.
The FCC essentially backed C-V2X technology in November, when it voted to dedicate 30 MHz of spectrum to the technology. Spectrum was previously devoted to the pre-connected car technology known as DSRC, but few DSRCs have been deployed.
As the 5G America report points out, the C-V2X standards define two basic types of connectivity. One is direct (PC5/Sidelink) connectivity which does not require cellular connectivity. The second is cellular connectivity, known as UU mode or vehicle-to-network (V2N) connectivity.
The report states that the chips under C-V2X can support both types of communication.
Cellular communications are already in use to support telematics services, and that’s where the telecommunications provider’s opportunities come in. And while 5G communication offers additional benefits, such as lower latency, the C-V2X can also support LTE communications.
Applications and synergies
A major application for the C-V2X standards is intelligent transportation systems (ITS), which will include networks of sensors, communication devices, and other infrastructure. While some ITS applications will rely on non-cellular PC5/Sidelink communication, others will use cellular connectivity and some will use both.
As the report points out, the Roadside Unit (RSU) is responsible for PC5 communications, but can also support cellular communications. The report cites the example of an RSU deployed at a traffic light that uses a cellular connection to receive signal phase and timing information from a traffic management center and a non-cellular PC5 link to distribute the information to a vehicle. Uses up.
The 5G America report sees a synergy between transportation planners/road operators and cellular providers, who can share the cost of equipping roads with RSUs. In the process, providers will also get roadside access to smaller cells.
Telecom Provider Connected Car Opportunities
Other connected car opportunities for telecom providers mentioned in the report:
- Special Service Level Agreements (SLAs) can be drawn up specifically for RSUs
- For example, RSUs may be able to enhance wider 5G network operations by, for example, sharing information about vehicle locations and speeds which can be useful in managing beamforming in an area.
- Cellular providers may be able to leverage their network infrastructure to provide virtual RSUs for areas where physical RSUs are not viable due to physical restrictions or low population
- V2N connection can be used to update software for vehicle operation and maintenance
- Cellular providers are well-located to operate MEC resources at CellSites and other locations to support vehicular services such as high-definition real-time maps, real-time traffic monitoring/alerts, and various entertainment content.
- Providers may provide peering with other mobile providers at MEC locations
- Providers can use network slicing to meet car manufacturers’ requirements for low-latency security applications and for convenience use cases that are less latency-sensitive
