Samsung Galaxy S20 and 5G: What you need to know – Tom's Guide

Published

 on


The arrival of Samsung’s Galaxy S20 lineup in stores is a big moment for 5G networking. For the first time, each one of the three new models offers 5G connectivity — it isn’t just a feature reserved for an expensive niche version of the phone. For most of the people picking up one of the new Galaxy S20 phones, this will be their first encounter with the newly launched wireless network standard that promises faster speeds and lower latency.

And if you fire up your Galaxy S20, Galaxy S20 Plus or Galaxy S20 Ultra expecting to be immediately transported to a world of 1 Gbps download speeds, chances are you’re going to be disappointed.

To be fair, there are faster 5G speeds out there that your new Galaxy phone will be able to take advantage of, giving you faster downloads and peppier performance. But just how fast depends on a lot of factors, from where you are to what cellular network you use.

For new Galaxy S20 owners, here’s a quick overview of what 5G is and what kind of performance you can expect from your new phone, both now and in the future.

Galaxy S20 and 5G: Which models can connect to 5G?

The short answer here is all of them — every new Samsung flagship from the $999 S20 all the way up to the $1,399 S20 Ultra is a 5G-ready phone. Samsung has opted to use the Snapdragon 865 chipset in its new flagship phones, which also means they’re equipped with an X55 modem that’s capable of connecting to all 5G networks

There’s one caveat here — the current version of the $999 Galaxy S20 only works with 5G networks built on low- and midband spectrum, so that phone is currently available from AT&T, Sprint and T-Mobile. That’s a key distinction for AT&T customers, as the carrier has just opened up its higher-speed 5G Plus service to everyone. (It had been limited to select customers previously.) The Galaxy S20 Plus and Galaxy S20 Ultra can benefit from the faster speeds of 5G Plus on AT&T; the Galaxy S20 cannot. 

Samsung plans to add compatibility with Verizon’s millimeter wave-based network — more on how that’s different from other 5G networks in a moment — with the Galaxy S20 expected to arrive at Big Red sometime in the second quarter. For now, both the Galaxy S20 Plus and Galaxy S20 Ultra work just fine on Verizon’s 5G network.

Galaxy S20 and 5G: Your wireless carrier matters

As noted above, different carriers have launched their initial 5G networks using different technologies. Verizon is all-in on millimeter wave, making that the focus of its 5G efforts to date. AT&T and T-Mobile have rolled out some 5G coverage based on millimeter wave — AT&T’s 5G Plus network is available in 35 cities and now open to all customers, while T-Mobile has millimeter wave nodes in half-a-dozen cities — but those two carriers have reallocated low-band spectrum to 5G to offer wider coverage to customers. Sprint uses midband spectrum for its 5G network.

So what does that all mean? Millimeter wave is much faster, and can reach the 1 Gbps speeds that 5G advocates have been touting. It’s best used in densely populated areas, though it has trouble getting around physical obstructions, so you often won’t find high-speed millimeter wave networks indoors. (There are exceptions like arenas where Verizon has deployed indoor 5G towers.)

5G networks that use low-band spectrum can cover a wider area, thereby reaching more people. Low-band 5G signals can also reach indoors. But the speeds aren’t as fast as what millimeter wave delivers — they’re only a modest improvement over the 4G speeds you currently get. In fact, in a recent study of 5G network performance, RootMetrics found that Verizon’s LTE speeds were faster than median speeds for T-Mobile’s 5G network and equal to AT&T’s median 5G speed.

Galaxy S20 and 5G: Speeds will vary widely

All that means is, what kind of 5G speeds you’ll get depends heavily on what carrier is providing your wireless service. My colleague Mark Spoonauer had a devil of a time getting decent 5G speeds using a Galaxy S20 Ultra on T-Mobile’s 5G network, with LTE-based phones loading pages faster than the S20 Ultra that was supposedly benefitting from 5G’s speed boost. Mark also couldn’t download a show off of Netflix when his S20 Ultra was connected to T-Mobile’s 5G.

Swapping out the T-Mobile SIM card for a Verizon SIM card did wonders, though, as Mark was able to register 1.4 Gbps-speeds and even download a TV episode in seconds. Of course, he had to stand outside to get that done.

It’s worth noting that when I tested the OnePlus 7T Pro 5G McLaren on T-Mobile’s 5G network in Maui, I had a much better experience (and not just because I was doing my testing in Hawaii). I didn’t see 1 Gbps speeds, but T-Mobile’s 5G network was certainly faster than LTE. And I could download all 3.5 hours of The Irishman in less than 3 minutes on T-Mobile 5G. Then again, that’s a different phone on an entirely different side of the country. Which brings up another important point.

Galaxy S20 and 5G: Where you are matters

5G is more available than it used to be, but it isn’t everywhere yet. And different carriers have launched their networks in different cities.

Verizon may have the fastest 5G speeds of any carrier at this point, but you’ll only find them in 34 cities as of this writing. (And even then, 5G coverage is limited to select neighborhoods.) AT&T’s low-band 5G network is bigger, reaching 80 cities, while T-Mobile boasts a nationwide network that can reach 5,000 cities. As for Sprint, it launched its network in nine cities last year, but it hasn’t really expanded much beyond that while it waits for its merger with T-Mobile to close.

Wondering which carrier provides 5G coverage in your area? Each of the Big Four carriers lists where they offer 5G service on their respective websites:

Bottom line: if you live in an area where your carrier hasn’t delivered 5G yet, you won’t be seeing any boost from 5G at all.

Galaxy S20 and 5G: Things will get better

The good news is that wireless carriers aren’t standing still with their 5G expansion. Expect to see carriers add coverage to more cities and improve coverage in areas they’ve already reached.

To that end, 5G networks initially built on one technology will eventually incorporate others. “Real 5G is a combination of sub-6 GHz and millimeter wave,” Qualcomm president Cristiano Amon said during the chipmaker’s technology summit this past December. Look for wireless carriers to start combining those technologies in their 5G coverage. And the Galaxy S20 Plus and S20 Ultra will benefit because the X55 modem inside works with all the technologies in play.

That may be small comfort now, when 5G coverage remains limited. But it means your phone’s 5G performance will improve over time — a positive step if you’re among the growing number of people holding on to your smartphone for more than two years.

Slack researcher discusses the fear, loathing and excitement surrounding AI in the workplace

Published

 on

 

SAN FRANCISCO (AP) — Artificial intelligence‘s recent rise to the forefront of business has left most office workers wondering how often they should use the technology and whether a computer will eventually replace them.

Those were among the highlights of a recent study conducted by the workplace communications platform Slack. After conducting in-depth interviews with 5,000 desktop workers, Slack concluded there are five types of AI personalities in the workplace: “The Maximalist” who regularly uses AI on their jobs; “The Underground” who covertly uses AI; “The Rebel,” who abhors AI; “The Superfan” who is excited about AI but still hasn’t used it; and “The Observer” who is taking a wait-and-see approach.

Only 50% of the respondents fell under the Maximalist or Underground categories, posing a challenge for businesses that want their workers to embrace AI technology. The Associated Press recently discussed the excitement and tension surrounding AI at work with Christina Janzer, Slack’s senior vice president of research and analytics.

Q: What do you make about the wide range of perceptions about AI at work?

A: It shows people are experiencing AI in very different ways, so they have very different emotions about it. Understanding those emotions will help understand what is going to drive usage of AI. If people are feeling guilty or nervous about it, they are not going to use it. So we have to understand where people are, then point them toward learning to value this new technology.

Q: The Maximalist and The Underground both seem to be early adopters of AI at work, but what is different about their attitudes?

A: Maximalists are all in on AI. They are getting value out of it, they are excited about it, and they are actively sharing that they are using it, which is a really big driver for usage among others.

The Underground is the one that is really interesting to me because they are using it, but they are hiding it. There are different reasons for that. They are worried they are going to be seen as incompetent. They are worried that AI is going to be seen as cheating. And so with them, we have an opportunity to provide clear guidelines to help them know that AI usage is celebrated and encouraged. But right now they don’t have guidelines from their companies and they don’t feel particularly encouraged to use it.

Overall, there is more excitement about AI than not, so I think that’s great We just need to figure out how to harness that.

Q: What about the 19% of workers who fell under the Rebel description in Slack’s study?

A: Rebels tend to be women, which is really interesting. Three out of five rebels are women, which I obviously don’t like to see. Also, rebels tend to be older. At a high level, men are adopting the technology at higher rates than women.

Q: Why do you think more women than men are resisting AI?

A: Women are more likely to see AI as a threat, more likely to worry that AI is going to take over their jobs. To me, that points to women not feeling as trusted in the workplace as men do. If you feel trusted by your manager, you are more likely to experiment with AI. Women are reluctant to adopt a technology that might be seen as a replacement for them whereas men may have more confidence that isn’t going to happen because they feel more trusted.

Q: What are some of the things employers should be doing if they want their workers to embrace AI on the job?

A: We are seeing three out of five desk workers don’t even have clear guidelines with AI, because their companies just aren’t telling them anything, so that’s a huge opportunity.

Another opportunity to encourage AI usage in the open. If we can create a culture where it’s celebrated, where people can see the way people are using it, then they can know that it’s accepted and celebrated. Then they can be inspired.

The third thing is we have to create a culture of experimentation where people feel comfortable trying it out, testing it, getting comfortable with it because a lot of people just don’t know where to start. The reality is you can start small, you don’t have to completely change your job. Having AI write an email or summarize content is a great place to start so you can start to understand what this technology can do.

Q: Do you think the fears about people losing their jobs because of AI are warranted?

A: People with AI are going to replace people without AI.

Biden administration to provide $325 million for new Michigan semiconductor factory

Published

 on

 

WASHINGTON (AP) — The Biden administration said Tuesday that it would provide up to $325 million to Hemlock Semiconductor for a new factory, a move that could help give Democrats a political edge in the swing state of Michigan ahead of election day.

The funding would support 180 manufacturing jobs in Saginaw County, where Republicans and Democrats were neck-in-neck for the past two presidential elections. There would also be construction jobs tied to the factory that would produce hyper-pure polysilicon, a building block for electronics and solar panels, among other technologies.

Commerce Secretary Gina Raimondo said on a call with reporters that the funding came from the CHIPS and Science Act, which President Joe Biden signed into law in 2022. It’s part of a broader industrial strategy that the campaign of Vice President Kamala Harris, the Democratic nominee, supports, while Republican nominee Donald Trump, the former president, sees tariff hikes and income tax cuts as better to support manufacturing.

“What we’ve been able to do with the CHIPS Act is not just build a few new factories, but fundamentally revitalize the semiconductor ecosystem in our country with American workers,” Raimondo said. “All of this is because of the vision of the Biden-Harris administration.”

A senior administration official said the timing of the announcement reflected the negotiating process for reaching terms on the grant, rather than any political considerations. The official insisted on anonymity to discuss the process.

After site work, Hemlock Semiconductor plans to begin construction in 2026 and then start production in 2028, the official said.

Running in 2016, Trump narrowly won Saginaw County and Michigan as a whole. But in 2020 against Biden, both Saginaw County and Michigan flipped to the Democrats.
