What Is 5G and How Fast Is It?

Matt Branda, director of 5G technical marketing for chipmaker Qualcomm, says every 10 years or so the telecommunications industry runs out of ways to innovate existing wireless technology, so developers start designing a new system—labeled with a "G"—from the ground up. And that's what's happening now.

"We've done a lot with 4G, but we're really pushing it to its limits at this point," he says. "So now we're looking at 5G and what it can do."

In addition to making mobile connectivity faster and more efficient, as previous generations have done, 5G could reduce the clutter of wired connections, too. In this vision of the future, instead of getting internet service from a cable coming out of the living room wall, you would get it from a router with an antenna equipped to receive a wireless signal from your service provider.

And despite the lack of a wired connection, the internet speeds would be a lot faster.

When 5G launches, says Branda, the initial peak speeds are expected to be about five times faster than those of 4G (or LTE) connections, which right now can reach up to 1 Gbps.

But don't get too excited. Just like today's peak speeds, those of 5G will be just that, peaks. They'd require perfect conditions, he says, and be more of an exception than the norm.

And that's okay, because there currently aren't any applications out there that require 5 Gbps speed. Branda notes that even 8K video streaming, which doesn't yet exist, would require only 100 Mbps.

What's more important is that minimum speeds will increase, too, providing a much more consistent experience for the average person, he says. In addition, 5G will ease the burden on 4G networks, letting them work faster and more efficiently.

But 5G has the potential to spark even more profound change. It could dramatically reduce latency—the speed at which a packet of data travels between two devices—from about 50 milliseconds to one. That's a crucial development for applications that require immediate reactions, says Mark Hung, a vice president at the technology research firm Gartner. Think telemedicine or remote-controlled drones.

"It's what some have started to call the 'tactile internet,' because latency is so low it feels like you can touch the internet," he says.

And, finally, moving to 5G would allow telecommunications providers to utilize new parts of the wireless spectrum, Branda says, boosting capacity at a time when the current options are stretched to the limits, but demand continues to soar.

"Companies spend billions of dollars on spectrum, because it's very hard to come by," he says. "That helps them provide consumers not only faster speeds, but also truly unlimited data at better efficiency."
