(Source: Qorvo) These technologies include: • V2X (DSRC, C-V2X) for automotive safety: V2X will communicate with vehicles, roadside infrastructure, and the overall environment to improve safety and create a path to autonomous driving. • 4G/5G cloud connectivity for vehicle OEM services: Applications for 4G/5G connectivity could include remotely diagnosing and monitoring car operations, making over-the-air software updates, performing teleoperation, and operating a fleet of shared, autonomous vehicles. • 4G/5G cloud connectivity for in-vehicle experiences: Drivers and passengers could use this type of connectivity to enjoy new in-vehicle experiences, from augmented reality-based navigation to rear-seat entertainment and music streaming services. • Wi-Fi for premium in-vehicle experiences and automotive dealer services: Drivers and passengers could enjoy many enhanced in-car Wi-Fi-based experiences. For example, efficient Wi-Fi connectivity throughout the vehicle could support ultra-high definition (ultra-HD) video streaming to multiple displays and enable screen mirroring from compatible devices and wireless back- up cameras. Wi-Fi could also support automotive dealer services, enabling automatic check-in, diagnostic data transfer, and software updates. • Bluetooth®: Drivers and passengers could stream high- fidelity music via Bluetooth, as well as benefit from practical services such as using a smartphone as a key fob. • SDARS (satellite digital audio radio services): With connectivity to satellite-based radio services, vehicle occupants are connected to their favorite radio broadcasts no matter where they are. The Coexistence Challenges of 5G and LTE By understanding the functions/benefits of the various technologies, we can better look at coexistence challenges— specifically, compatibility with 5G and LTE. 5G, the fifth generation of cellular technology, increases data rates, reduces latency, and enhances the flexibility of wireless services. The 5G spectrum is classified as sub-6GHz and millimeter wave.
