For autonomous car technology to be unlocked, many experts agree that large-scale adoption of 5G—the next-generation wireless technology—is required. The current 4G network is fast enough to online stream full HD content and play online games, but it can’t support safer and smarter autonomous cars.
Said Nokia’s Jane Rygaard in a recent interview with the BBC: “We need to look at how long it takes for the message to be transmitted between sensors and then get to the computer in each car, and then how long it takes for the computer to make a decision, and all of this has to be in less time than a human would take to make a decision—2 milliseconds. We need a network supporting this, and 5G is that network.”
The current 4G network is simply not fast enough to provide the capability to give autonomous vehicles human-like reflexes that may have prevented the Uber vehicle fatality.
Driverless cars are just one of the many incredible technologies that are likely to be ushered in with 5G. Virtual reality and artificial intelligence are two more examples of the breakthroughs that we can expect once the data network catches up with technological advancement.
Evolution of the Networks
The wireless data network has advanced steadily over the past 30 years, and some life-changing technologies have been hot on its heels. The modern evolution began in the early ’80s with the introduction of the first-generation analog cellular system. Though cell phones were still relatively rare, people could finally talk to each other on the go.
By the early ’90s, second-generation and 2.5G mobile systems enabled people to send text, but it wasn’t until the start of the new millennium that people had access to broadband-speed internet through 3G. Phones evolved from devices for making calls to a tool for multifaceted communication, entertainment, shopping, and much more.
4G is the latest evolution, and it offers enough bandwidth and speed to allow real-time information- and location-sharing. This evolvement enabled the sharing economy and helped give birth to companies like Uber and Lyft. However, it’s still not fast enough to support technologies that require the speed of human reflexes. That’s where 5G comes in.
Why 5G is Crucial for Autonomous Cars
The fifth-generation wireless technology is expected to connect almost everything around us with an ultra-fast, highly reliable, and fully responsive network. 5G will allow us to leverage the full potential of advanced technologies such as artificial intelligence, virtual reality, and the Internet of Things (IoT).
Self-driving cars use hundreds of sensors to make vehicles faster and smarter. These sensors generate unprecedented amounts of data, much more than any other IoT adoption would. Handling, processing, and analyzing this amount of data requires a much faster network than the existing 4G technology. Autonomous cars, systems require incredible data processing capabilities and speeds needed to mimic the timing of human reflexes.
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, and that is why we need much faster ASIC processing technology and products,” Laskar said.
The world’s leading semiconductor companies, such as Intel and Qualcomm, are advancing toward an ASICs revolution, combining large available bandwidth at 5G frequencies with new innovative digital radio and antenna architectures. Simply put, these companies are creating chips to turn autonomous vehicles into mobile data centers, allowing driverless cars to make real-time, complex decisions.
Market watchers say that 5G, when adopted at the full scale, will offer internet speeds up to 100 times faster than 4G. It will present exciting possibilities for the automobile industry used for vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) connectivity. Furthermore, the technology’s low latency will make these vehicles extraordinarily safe and reliable on the roads—safer than vehicles today that are operated by people.
