Living On The Wireless Edge With AI And 5G

SwissCognitiveWe are at the cusp of something truly transformational, driven by two much-hyped yet groundbreaking technology mega trends: artificial intelligence () and 5G. Together they make possible things that never existed and seemed utopian not too long ago.

A vivid example of this is the rise of self-driving vehicles. Notwithstanding the recent setbacks in the first iteration of self-driving, a fully autonomous self-driving vehicle will be the epitome of and 5G technology.

When you enter a fully , one without a driver or even a steering wheel, the vehicle does the driving for you while you sit back and relax. To make that possible, a number of complex things have to happen. The car has to continuously collect millions of data points from its thousands of sensors, dozens of cameras and multitude of other monitors. This data is fed to highly sophisticated algorithms, the “intelligence” of the self-driving system. These algorithms churn the data and instruct the car to drive itself safely.

If you apply the traditional approach to self-driving, this intelligence will reside in a centralized . The data collected from the vehicle will be hauled to the for processing, and instructions will be sent back to the vehicle. However, when you consider a moving vehicle in which decisions have to be made in split seconds, this approach simply won’t work. For example, if the vehicle sees any obstacle, it has to quickly determine whether it is another moving vehicle, a bike, a live person, an animal or just debris on the road – and act accordingly. The turnaround time between sensing and action must be extremely short. So, what is the solution?

Intelligent Or Intelligent Edge?

The ultimate question for any effective system is: Where should the intelligence lie: in a centralized or in a device? In engineering lingo, devices are referred to as “edge devices” because they are at the edge of the network, while the is at the center. This dichotomy is applicable to many applications and use cases, be it extended reality (/), medical applications, , industrial, consumer, etc. The obvious choice is to keep intelligence at the edge or as close as possible to it. However, this is not practical because edge devices typically have limited processing power and are battery powered. Therefore, they cannot replicate the prowess of the .

The other option would be using a fast link, like 5G, between the and edge devices. However, this is not practical because edge devices generate huge amounts of data. Hauling all that raw data for trillions of devices would be onerous and expensive, even for 5G.

As with many things in life, the answer is a healthy middle: Move the intelligence that deals with immediacy toward the edge. Keep processing-intensive functions in the . And use 5G to connect them intelligently. That’s exactly what the tech industry is working toward. It helps that tech giants such as Amazon, Facebook, Google, Huawei Intel, Microsoft, Qualcomm and others have expertise in both and communications.

Moving Toward Edge Intelligence

Moving toward edge intelligence simply means adopting distributed architecture for modern systems, wherein edge devices have the intelligence to not only collect and analyze the data that they send to the , but also make crucial time-sensitive decisions. Thanks to Moore’s law, devices, be they smartphones or IoT devices, now have enough processing capability and power efficiency to run algorithms.

Edge intelligence in no way undermines the importance of the . The is and will remain a crucial part of the system. The development, training and fine-tuning of algorithms will still happen in the . That is transferred to edge devices for fast decision making. This architecture can be scaled to support trillions of devices in the future.

Another important aspect of edge intelligence is privacy and security. It allows confidential information to be securely and privately stored in the edge instead of the . This is even more important for commercial enterprises that don’t want their trade secrets to get out of their systems.
