Verizon successfully tests edge computing on a live 5G network, cutting latency in half

HOUSTON, Jan. 31, 2019 (GLOBE NEWSWIRE) -- Verizon engineers have successfully tested edge computing - putting compute power closer to the user at a network’s edge - on a live 5G network, cutting latency in half. Low latency - the time it takes for information to make a roundtrip - is important today for applications like online gaming and video streaming, and will be increasingly vital as next generation wireless experiences emerge.

In a newly formed 5G test bed in Houston, Verizon engineers installed Multi-access Edge Compute (MEC) equipment and MEC platform software into a network facility closer to the network edge, thus decreasing the distance that information needs to travel between a wireless device and the compute infrastructure with which that device’s apps are interacting. 

In this test, the engineers used an Automated Intelligence (AI) enabled facial recognition application to identify people. Using MEC equipment located in the network facility, the application was able to analyze information right at the edge of the network where the application was being used (instead of traversing multiple hops to the nearest centralized data center).  As a result, the engineers were able to successfully identify the individual twice as fast as when they duplicated the experiment using the centralized data center.  Putting the compute power closer to the user at the network edge greatly decreased the time to deliver the experience – a key benefit of the Verizon Intelligent Edge Network.

“For applications requiring low latency, sending huge quantities of data to and from the centralized cloud is no longer practical. Data processing and management will need to take place much closer to the user. MEC moves application processing, storage, and management to the Radio Access Network’s edge to deliver the desired low latency experiences, thereby enabling new disruptive technologies,” said Adam Koeppe, Verizon’s Senior Vice President for Network Planning. “This shift in where the application processing occurs, the inherent capabilities of 5G to move data more efficiently, and our use of millimeter wave spectrum is a game-changer when it comes to the edge computing capabilities we can provide.” 

Why latency is important for next generation networks

As 5G rolls out, we will see a rise in wireless applications that are heavily dependent on low latency. Consider, for example, vivid, immersive Virtual Reality (VR). This requires accurate syncing of video playback with the physical movements of the user. Any lag, even small, can lead to imperceptible differences between what a user sees and experiences, which is why some people get dizziness or nausea when using VR. If information for the headset is travelling over a network, you need super low latency to ensure there is no lag (wait time). In a future where cutting edge innovations like self-driving cars and remote-controlled robotics are envisioned, having near-zero latency is even more critical.  Hosting events at venues, industrial automation, retail, gaming, and video analytics with AI will all benefit from MEC technology.

What is edge computing and MEC?

As cloud computing has taken hold, there has been a trend to use large, centralized data centers where massive amounts of computing and storage take place. In the era of 4G, this approach enabled app development and innovations that significantly altered the way we use mobile devices. However, this approach has some drawbacks in how data flows. When someone wants to stream video, for example, their commands may have to travel several states away to access the needed storage or computing requested, and then data travels that same distance back. The distance is not really noticeable most of the time, adding up to mere milliseconds, but in a future where near zero latency is needed every millisecond matters.

Lower latency is one of the numerous benefits to come from introducing MEC at the edge of the network, but it is not the only benefit.  An increase in reliability, energy efficiency, peak data rates, and the ability to process more data through more connected devices are also benefits of introducing MEC technology.

“To achieve near-zero latency, where data moves many times faster than the blink of an eye, having computing functions closer to the user is a vital step,” said Koeppe. “With this test, we have shown how much of an impact the move towards a MEC-based network architecture can make.”

Verizon Communications Inc. (NYSE, Nasdaq: VZ), headquartered in New York City, generated revenues of $130.9 billion in 2018. The company operates America’s most reliable wireless network and the nation’s premier all-fiber network, and delivers integrated solutions to businesses worldwide. With brands like Yahoo, TechCrunch and HuffPost, the company’s media group helps consumers stay informed and entertained, communicate and transact, while creating new ways for advertisers and partners to connect. Verizon’s corporate responsibility prioritizes the environmental, social and governance issues most relevant to its business and impact to society.
