As 5G rolls out across the planet, it’ll offer subsequent generation of mobile connectivity experience powered by a dramatic increase in speed and low latency. it’ll also open up possibilities for a brand spanking new mobile, gaming, health, edge, and industrial applications – with tons of hype and expectation. While we tend to associate 5G’s impact on our own personal devices, like phones and tablets, one among the areas where we’ll likely see the foremost significant impact is going to be automotive.
As transportation marches towards autonomous vehicles (we’re almost there, but we’re getting closer), connected cars are starting to look more and more sort of a small data center. These data hubs are going to be continuously pushing and receiving, different sorts of data through the 5G network, with automotive safety, because of the primary goal. Here are three examples:
1. Next-Generation Maps
We’re already won’t to our maps being updated with live traffic conditions, but maps will evolve to soak up and deliver far more information in real-time. As we glance into the near future, vehicles will amass abundant sensors and cameras, and that they are going to be constantly surveying the road and their surroundings. When a car will recognize something different within the environment, like new roads, construction, a change within the number of lanes or lane location, it’ll send that information to the cloud. There, a central database is going to be updated, and therefore the information is going to be pushed bent other vehicles, and potentially others within the road network (like pedestrians and therefore the roadside infrastructure) in almost real-time.
2. C-V2X Alerts
V2X (Vehicle-to-Everything) communication is that the technology that permits cars to speak with the various parts of the traffic system which will affect the vehicle, and the other way around. This includes vehicles, infrastructure, and pedestrians.
Until 5G infrastructures have sufficient coverage and are tested to meet automotive standards, V2X will be rolled out as DSRC (Dedicated Short Range Communication). DSRC allows vehicles to communicate with low latency (<100ms) directly with other vehicles or roadside units (RSU) with a line of sight range of up to 300m. While this is already a huge evolution from where we are today, with 5G, we’ll see C-V2X (Cellular V2X) that will take this to a whole new level.
5G technology will allow cars to use the direct PC5 interface (where a tool can communicate with another device over an immediate channel) also because of the network Uu interface, which uses cell towers for the radio access networks. We’ll see even lower latency with 5G, the power to speak up to 600m for PC5 direct communication, and up to 2km with Uu. this suggests V2X are going to be ready to include much more moving parts within the vehicle’s view, and longer (through larger distance) to react to road conditions ahead like accidents, lane closures, icy or wet roads, and debris.
Furthermore, the PC5 interface also allows the vehicle to not only communicate with other cars and RSUs, but it’ll even have the potential to speak with pedestrians and cyclists via their cell phones and potentially other devices. Why is that this important? It could prevent accidents resulting from blind corners or people entering the road between cars. Both the vehicle and pedestrian/cyclist would be notified and may take appropriate action.
3. Software Updates and Services
The third feature which will be enhanced by 5G is over-the-air (OTA) software updates. While this exists already today on some vehicles, it’ll become standard on all vehicles within the future. As we glance at the cars of the longer term, the amount and sort of applications, sensors, and cameras will still increase, and that they will all believe interdependent services. of these applications will get to regularly be maintained and updated.
The algorithms behind autonomous and smart vehicles will still learn and mature as they capture data and push it bent cloud data centers for analysis. As these software elements get smarter, they’re going to then be updated and dispatched over 5G through the vehicle’s OTA module as a part of the telematics gateway. These sorts of updates will become as common, and certain as frequent, as we’ve been familiar with our smartphone updates.
Enhancing Automotive Safety with Storage
How does data storage play a task altogether? For one thing, maps, V2X security keys, application software, data logging, OTA buffering, and therefore the many lines of software code that exist already in vehicles are, and can still be, stored within the vehicle on NAND flash-based products.
With V2X going far beyond just the vehicle, storage also will be vital in RSUs, smart city devices like traffic signals and therefore the edge and cloud data centers that gather and process this ecosystem of knowledge. But how do these pieces work together? Last month joined the Automotive Edge Computing Consortium (AECC) to assist drive open distributed computing infrastructure for connected vehicles along with side mobile network operators, automotive manufacturers, and communication leaders.
While 5G will enable massive automotive data to maneuver quickly with low latency, our job is to create the optimal foundation for data to be captured, preserved, accessed, and transformed, so drivers and passengers are going to be safer on the road.
