What is 5G? The definitive guide to the 5G network rollout



Here’s everything you need to know about what 5G is

That new device may hit download speeds of 1 Gbps (but only on a high-band 5G network) and theoretically hit a peak of 10 Gbps.

AT&T is sticking by its decision: “We’ve been talking about 5G Evolution for a while now. Faster connectivity and no latency could also revolutionize hospitals, enabling holograph-assisted surgeries. First, there are only a handful of 5G-compatible smartphones on the market, though that number is growing. The results showed that 47% of AT&T subscribers who own iPhones think their device is 5G-capable.

Don’t confuse AT&T’s 5G plans with the 5GE logo that appears on AT&T customers’ phones. (That’s not just phones, but rather connected devices, too. With 5G, that could actually happen. That means you’ll be able to download full-length movies in seconds, but it will also open up a world of possibilities we can’t even imagine yet. That’s exponentially better than AT&T’s existing LTE network, which averaged download speeds of 32.91 Mbps earlier this year.

Here’s how 4G and 5G speeds compare.
The dangers of 5G

There is no evidence to suggest that 5G is dangerous to your health, and yet people are still concerned.

That’s why both sub-6 and mmWave are necessary to make 5G widespread and high speed.

First there was 2G, a set of standards governing wireless telephone calls. 4G delivered speeds that enabled video streaming and an entire economy of apps that need sustained, reliable connectivity.

In 2017, the 3rd Generation Partnership Project, the group that creates the rules for wireless connectivity, issued the non-stand-alone standard for 5G, which allows 5G to coexist alongside 4G. But that’s only part of what 5G is — the faster speeds will mean so much more than just higher-quality streaming and lightning quick downloads.

“5G will be the post-smartphone era,” Robert J. Millimeter-wave frequency was previously unused, and the advent of 5G has given carriers access to the spectrum that will enable the faster speeds we expect with the new standard.

But mmWave has a few drawbacks: Because it’s so high-frequency, the waves don’t travel long distances. Indeed, at Qualcomm’s annual developer get-together in December, Qualcomm president Christian Amon said that real 5G will be a combination of the low, mid, and high-band frequencies.

To that end, Sprint is using its existing midband (2.5 GHz) spectrum to build out its 5G network.

That means your existing smartphone won’t catch a 5G signal (unless, of course, you bought one of the handful of 5G-ready phones that went on sale last year). Similarly, AT&T’s 5G Plus relies on mmWave in the 35 cities it’s available in, but the carrier also has a low-band network that now reaches 80 cities with a goal of completing a national reach by mid-year.

Rollout: When can I expect 5G?

5G is already here, but unless the stars of your location, the wireless carrier you subscribe to and the smartphone you own are perfectly aligned, you probably can’t use it yet.

AT&T, Verizon, T-Mobile and Sprint have all launched their 5G networks, but there are caveats. to build out 5G networks and test them with devices equipped with 5G radios that comply with the new standard. In fact, they can’t even travel through windows or buildings. In fact, one in three Americans think they already have 5G, according to a recent study. In June 2018, the 3GPP finalized the standard for stand-alone 5G. “Phones are the first place to launch because [they’re] such an anchor in our lives from a connectivity standpoint.”

That’s about to change.

Lower latency will make augmented reality and virtual reality more useful — and eliminate nausea — because there won’t be any lag. At 2.5 GHz, a signal can travel farther but not as fast as with mmWave. When I tested AT&T’s 5G Plus network in Las Vegas last year, I hit 900 Mbps over 5G. 5G networks operate on different frequencies with sub-6 GHz and millimeter-wave (20-60 GHz) at the low and high ends of the spectrum.

Carriers were already using sub-6 spectrum for existing LTE networks, and now they need more of it to build out 5G. But in rural areas where there are few buildings or cell towers, mmWave won’t work. (More on those in a moment.) And with the exception of T-Mobile’s newly launched nationwide service, the carriers have launched service only in some parts of certain cities, with little overlap. AR glasses and VR headsets haven’t yet cracked the mainstream, but tech companies are betting that these devices will eventually replace our smartphones. The company is reportedly waiting until 2020 to go all in with 5G with the iPhone 12.

Huawei and ZTE also have 5G phones, but those are only available in other countries.

what is 5gThe Snapdragon 865 ands 765 chipsets from Qualcomm should mean more 5G-ready phones in 2020. That logo translates to “5G Evolution,” AT&T’s expanded service with advanced LTE technologies, such as 4X4 MIMO, which doesn’t hit the speeds we expect from 5G (or even match Verizon’s current 4G service, in our testing). After years of hype about gigabit speeds that will let you download full-length movies in mere seconds, 5G became a reality last year. We were pretty public about what we were doing and what we were deploying,” Igal Elbaz, senior vice president for wireless technology at AT&T, told us at CES 2019.

We entered 2020 with half-a-dozen 5G-capable smartphones on the market: Samsung’s Galaxy S10 5G, Note 10 Plus 5G, the OnePlus 7 Pro 5G and OnePlus 7T Pro 5G McLaren, LG’s V50 ThinQ 5G and the Moto Z3 or Moto Z4 with 5G Moto Mod. (Image credit: Tom’s Guide)

5G could transform schools by enabling virtual- and augmented-reality experiences that will bring concepts out of textbooks and into real life for kids in classrooms. Even AT&T’s expanding low-band network is available in a limited number of areas at the moment.

What’s more, it’s evident many smartphone users aren’t sure what 5G is. LTE can’t compare, but I clocked over 200 Mbps on an iPhone running on AT&T’s 5G E (advanced LTE) network. But that should change as more cities come online and more 5G devices become available.

Overall, 2019 had been the year that 5G starts to take off, but 2020 is when next-generation networks will have a meaningful impact on the masses. The hand-off should be imperceptible.

This will be especially useful in areas of the country where 5G networks will take longer to get off the ground.

Existing 4G networks will also play a role in carriers building out their 5G coverage, as technologies like dynamic spectrum sharing will allow carriers to share their spectrum between 4G and 5G uses.

And the improvements carriers are making to their networks to prepare for a nationwide 5G rollout will make 4G better, too. “2020 will be the year of scale of 5G,” Qualcomm’s Amon promises.

By year’s end, we’ll not only see the first 5G iPhone, we also expect most wireless networks to offer nationwide coverage. AT&T is also carrying the phone, but only for business customers and developers. Topol, Intel’s general manager for 5G business and technology, said during an interview at last year’s Mobile World Congress. On the roads, 5G could make self-driving cars safer, because communication between vehicles and infrastructure will become instantaneous.

“It’s not just speed and latency, it’s so many other things,” Verizon chief product development officer Nicki Palmer said during the December 2019 Qualcomm tech summit on 5G. (Image credit: Tom’s Guide)

The $1,299 Galaxy S10 5G is available on Verizon, Sprint and T-Mobile. Qualcomm’s 700 series of processor is aimed at less expensive phones than the flagships that will feature the Snapdragon 865, so industry observers think that a wider variety of 5G-capable handsets will be available in 2020.

“First and foremost in 2020, it’s about getting [5G] in smartphones,” said Ryan Sullivan, Sprint’s vice president of product engineering.

That’s starting to take hold, now that the Galaxy S20, Galaxy S20 Plus and Galaxy S20 Ultra are here. When your device drops a 5G signal, it will fall back on LTE. “They may not all be a 2020 thing, but you start to see some of those new use cases and new product categories emerge.”

To that end, Qualcomm has released its XR2 mixed reality processor with 5G connectivity, and at the end of February, unveiled a reference design built around the chip that it says will accelerate development of new mixed reality experiences.

what is 5gQualcomm has developed a 5G-ready processor for AR- and VR devices. That’s when we’ll begin to see the full potential of 5G. “This transition from 4G to 5G is even bigger and frankly much more revolutionary.”

This isn’t going to happen overnight, but expect major shifts thanks to 5G in the next five years. Why?

For years, the belief that radio waves can cause brain cancer in humans has spread, seemingly affirmed by a 2000 scientific study of high-frequency waves and their effect on human cell tissue. Then 3G arrived, making it possible to surf the internet on a smartphone.

“Connected PCs, connected IoT products, connected AR/VR, connected gaming consoles, things like that — we see all of those on the horizon,” Sprint’s Sullivan said. Qualcomm’s Amon predicts that there will be 200 million 5G subscribers by the end of 2020, and that there will be 2.8 billion 5G connections by 2025. All four wireless carriers flipped the switch on 5G in the U.S. (That may be why AT&T just opened up its mmWave-based 5G Plus network to all customers.) The LG V60 ThinQ is following this spring, and other 5G-ready phones will be announced long before Apple takes the wraps off the iPhone 12.
5G beyond phones

People equate the G’s — 2G, 3G, 4G and now 5G — with smartphones, because that’s always been the place where we’ve been able to see an indicator of what kind of connectivity we’re getting. The LG V60 ThinQ has also been announced, and it’s a 5G phone as well.
Sprint and Verizon have committed to offering 5G-connected laptops this year, Qualcomm says.

What is 5G?

5G is the fifth generation of wireless communication standards. We’ve seen that play out in our testing of Sprint’s network, which doesn’t deliver the 1 Gbps speeds that mmWave-based networks from its rivals do, but does allow you to catch a signal more reliably.

T-Mobile launched its 5G network using mmWave in a half-dozen cities, but now features a nationwide 5G service using low-bad spectrum that can reach 5,000 cities in addition to some rural areas.

Apple decided to sit 2019 out — there’s no 5G iPhone 11. The S20 Plus and S20 Ultra can work with any type of 5G network, be it built on mmWave or low- to midband spectrum. (Image credit: Tom’s Guide)

The number of 5G phones is expected to increase this year, thanks in large part to the Snapdragon 865, a newly unveiled mobile processing platform designed to work with 5G modems. during 2019, and you can now buy 5G phones that can take advantage of faster speeds on those networks. A recent New York Times report examined that study and found it to be based on a misunderstanding of the human body — specifically, the skin’s ability to shield the brain from radio waves.

Our colleagues at Live Science have also looked into the dangers — or lack thereof — that 5G can pose, and found that while there is no reason to be alarmed about the rollout, more studies will (and should) be conducted as 5G becomes more widespread to determine its impact.

AT&T continues to expand its low-band 5G network, which is now available in 80 cities. (The Moto phones require a pricey accessory; it can’t connect to 5G on its own.)
