5 things to know about 5G if you work in the auto industry

Let’s start with the simple facts first: from a peak speed perspective, 5G is 100 times faster than 4G. This means that during the time it took to download just one piece of data with 4G the same could have been downloaded 100 times over a 5G network. You can just imagine how this speed is important for a connected car when it comes to the amount of data that will need to be shared.

According to Dr. Joy Laskar, CTO of Maja Systems, future autonomous cars will generate nearly 2 petabits of data, which is equivalent of 2 million gigabits. “With an advanced Wi-Fi connection, it will take 230 days to transfer a week-worth of data from a self-driving car,” Laskar said.

With 5G, that time would go from 230 days to just over 2 days.

5G also means low latency, as in a matter of milliseconds.

Latency is the amount of time it takes to send information from one point to another. We encounter it everyday when we drive, and make a decision to break suddenly: latency is the amount of time between our brain sends the instruction to our foot to push down on the brake in this example. When it comes to networks, we usually talk about the difference between the 20 milliseconds of our current 4G networks to the 1-5 milliseconds of the 5G network.

However, there’s even a larger difference when it comes to self-driving cars.

Human reaction speed is a bit above 200 milliseconds, leading to accidents every day. 5G’s 5 millisecond latency is practically real-time, which can be used to provide the user with additional safety information before it is visible, for example roadworks, fast moving emergency vehicles and visually hidden pedestrians about to cross the street. These cooperative Advanced Driver Assistance Systems (ADAS) will help the driver to drive safely and avoid accidents.

Reliable communication means guaranteed delivery of time-critical information. For example, for remotely driving an autonomous vehicle in real-time in case its autonomous function fails. There is no other alternative than cellular networks for enabling such services. 5G cellular technology is designed from day one for ultra-reliable communication with low latency to enable complex machine centric use cases, including autonomous cars in dense urban as well as high speed scenarios. We expect adoption of fully autonomous capabilities in limited areas initially leveraging 5G signal coverage, with long-term evolution towards fully autonomous transport eco-system for maximizing safety, efficiency, and sustainability.

Thanks to these three elements—increased speed, lower latency, and increased reliability—a whole new generation of exciting use cases can be unlocked.

In Europe, the 5GCAR project, led by Ericsson, is helping to develop an overall 5G system architecture. As part of their work, they identified a number of new use cases that need 5G to unlock the future of transportation, from lane merge coordination to long range sensor sharing and increased protection for pedestrians. 

5G won’t just make connecting cars easier: it will make manufacturing cars easier as well.

5G is about to change manufacturing as we know it through secure and almost real-time connectivity that will result in transformative productivity, speed and efficiency improvements. The car industry will be among the first to benefit.

But don’t just take our word for it: ask Mercedes-Benz. We recently teamed up with Telefónica Germany to enable 5G car production via a private 5G network for Mercedes-Benz at the company’s Sindelfingen plant in southern Germany.

Jörg Burzer, Member of the Divisional Board of Management of Mercedes-Benz Cars, Production and Supply Chain, said: "With the installation of a local 5G network, the networking of all production systems and machines in the Mercedes-Benz Cars factories will become even smarter and more efficient in the future. This opens up completely new production opportunities.”
