Here are four more tech acronyms related to C-V2X that will soon enter the mainstream vernacular as the Intelligent Roadway System rapidly advances.

1. PC5: AKA sidelink for V2V, V2I and V2P

PC5 may sound like the latest video game console to top your kid’s Christmas list, but this short range direct communication interface is the secret sauce that sets C-V2X apart. Unlike DSRC, which employs technology derived from what’s in the Wi-Fi router in your home, PC5 is designed to benefit from advances in LTE technology to offer increased communication range (~2X), better non-line-of-sight (NLOS) performance, enhanced reliability, higher capacity, and better congestion control in denser environments. PC5 gives the capability to our transportation system to maintain the connectivity that moving vehicles require – and which is needed for safety-critical communication.

C-V2X has the capability of network communications in addition to direct communications, giving roadway operators state-of-the-art ability to deliver safety and mobility applications and services, in a manner that is cost-efficient.

2. V2N – Vehicle to Network

Not all in-vehicle communication is urgent – sometimes drivers just want to know which route will speed up their morning commute. Vehicle-to-network (V2N) systems connect vehicles to the cellular infrastructure and the cloud so drivers can enjoy connected tech like traffic updates and travel notifications. By leveraging existing cellular networks and mobile ecosystem support, C-V2X offers new business models and economic benefits, which is likely to expedite the deployment of C-V2X-equipped vehicles.

3. 5G – Fifth generation wireless

If you’ve got a device with internet access, you’ve probably heard of 5G, but not necessarily how it’s going to revolutionize driving as we know it. In the very near future, 5G will be the backbone of how we all communicate with each other and our “things,” and this can include safety in between vehicles. C-V2X today provides an evolutionary step towards the use of 5G tomorrow. The benefits of this evolution will include an agnostic, backwards compatible platform that ensures road operators and OEM’s can cost effectively take advantage of new advances in 5G wireless communications.

4. FOTA – Firmware over-the-air

Cars that can talk to each other understandably raise concerns about cybersecurity. One of the key ways to prevent attacks is to update software regularly, and that’s where Firmware Over-the-Air (FOTA) works its magic. Already an established cloud technology for mobile phones, its application to the automotive world helps to tackle the rapid evolution of connected car systems. FOTA can update a car’s software anywhere – at the showroom, in the garage, on the road. As our vehicles become more computer than machine, FOTA is one of the critical mechanisms for maintaining an up-to-date, secure system more effectively.
