Network latency refers to the time required for a packet of data to travel round trip between two points. For 5G technology to realize its potential, network latency must be all but eliminated.
This is a pivotal challenge for any carrier building a true 5G network. If someone streams a movie in HD, casts an NBA game to their 4K television or collaborates with distant colleagues in a virtual “sandbox,” latency is of critical importance. High latency is a recipe for frustration, inefficiency and—where immersive digital experiences are involved—even nausea. As a general rule, the lower the network latency, the better the user experience.
What causes network latency?
Any number of factors can contribute to network latency, including the speed and available bandwidth on the network, or the sheer size of the transmitted data packet. Network latency will be faster than the blink of an eye on the nation’s first 5G network. And users will soon reap the benefits, sending and downloading massive amounts of data at speeds scarcely imaginable just a few years ago. When latency is lowered, the bar is raised.
As more and more devices connect, the demand for robust, seamless network responses will not go away; it will explode. And it’s not just more phones or tablets that will be trying to connect. Factory machinery, traffic lights, elevator banks and thousands of other massive systems will be clamoring for bandwidth in the very near future.
In fact, low latency is a precondition for the fulfilment of massive IoT—the ability for heavy industry and other big data enterprises to innovate and operationalize efficiencies on a global scale, in near real time. Network providers that fail to meet this challenge will be left behind.
Gigabits-per-second throughputs and single-millisecond latencies are set to become the new normal. Tomorrow’s innovators will demand and expect robust, reliable network service—not just sometimes, but all the time.
The next big technological innovations are coming in 5G to serve … business, education, government and consumers.

What are benefits of lowered network latency?
“The next big technological innovations are coming in 5G to serve the future needs of business, education, government and consumers,” says Nicki Palmer, chief network engineering officer and head of wireless networks, Verizon Wireless. “Low-latency services and massive IoT scale will thrive … [meaning] more connected services and devices, and higher broadband capacity that can benefit our entire society.”
Reducing network latency can also help ensure sharper, more vivid immersive experiences. One of the trickiest challenges of virtual reality goggles is syncing the video playback with physical movement of the goggle wearer. If one of these elements is out of step, it’s a surefire recipe for dizziness and in some cases, nausea, and high latency is one of the biggest culprits.
But over Verizon’s 5G network, VR experiences can be as rich and detailed as a motion graphics designer can imagine. Immersive content can be cast to the VR headset with startling speed and precision, making the environment pop—and blowing the wearer’s mind.
What does lowered network latency look like in the real world?
Verizon has recently conducted a number of tests and simulations—some quietly, others on the world’s biggest stages—to illustrate the benefits of low network latency. With observed latency figures of 1 millisecond or less, these applications give just a hint of what can be accomplished over our developing 5G network, when precision goes hand in hand with imagination.
Verizon and KT showcase Samsung 5G tablets, conduct video call
On Sunday, February 4, Verizon chairman and CEO Lowell McAdam and KT chairman and CEO Chang-Gyu Hwang successfully conducted the first-ever pre-commercial 5G video call on two fully functioning prototype 5G tablets. Mr. McAdam participated on the international call from Minneapolis MN. Mr. Hwang participated from Seoul, Korea.
