In the 5G race of 2019, consumers were the real losers

"Commentary: The carriers were largely in testing mode, and consumers were the guinea pigs.

5G wasn't a complete bust, but it didn't live up to the hype either.

It's the beginning of 2019, and the hype for 5G is immense. Verizon talks about all of the different applications at a keynote at CES. A few next-generation networks had already turned on in December 2018, and after years of big promises and anticipation, it looks like the game-changing technology is finally going to show up in a big way. 
Then 2019 happened. 
Those networks that turned on a few weeks prior? Consumers still don't have access to some of them. One initially touted a single robot customer. 
The handful of networks in the US that went live in the middle of the year suffered from extremely limited range. Overseas, coverage was promising, but likewise spotty. The broader range flavor of 5G, which promises to cover more people, launched this month with an incremental increase in speed over 4G. 5G smartphones have been pricey, suffered from weak battery life and been limited in the types of 5G bands they could access. 
Watch this: 5G kind of sucked this year. Here's how it may get better....
Game-changing this is not. 
The shaky launch of 5G this year underscores the fact that the wireless industry is still in testing mode when it comes to the technology, and you're the guinea pig. But the need to be first, which has driven many of these carriers, ultimately hurt consumers by over-promising and under-delivering. Yes, speeds can be 100 times what you could get on 4G, but it's not worth much if it's limited to an intersection. 
"Carriers made it sound like 5G would dominate the world in 2019/2020," said Lopez Research analyst Maribel Lopez. "The reality is that we've seen a few phones and a few cities deployed."
Going into 2020, I hope there's less of a focus on who's first, and more on simply offering a service that gets close to fulfilling the many promises made over the last few years. That also includes devices that are more affordable and can offer more flexibly to hop between carriers and different flavors of 5G. 
There's reason to be hopeful, as the technology matures and further deployments and upgrades continue. 
But after a rough 2019, you'll excuse me if I remain skeptical. 

5GE is a thing. Really

Getting 5G to consumers first meant so much to AT&T that it changed the definition of its 4G network. At the beginning of the year, the company rebranded its LTE Advanced network, which other carriers had built out as well, as 5GE, claiming it was on an evolutionary path to 5G. The 5GE symbol showed up on phones where the 4G symbol used to be. 
AT&T emphasized the 5G bit, causing a lot of confusion and leading many consumers to believe they had 5G. It sparked a lawsuit from Sprint, which was settled
AT&T later toned down the marketing of 5GE, including making the Evolution bit more pronounced, but the confusion had already set in. The company wasn't available to comment on its latest use of the term. 
AT&T declined to comment directly on the market confusion caused by 5GE, instead referencing the work its done to invest in its network. 
"We continue to push the boundaries of what's possible with existing network technologies, and results throughout 2019 in studies like Ookla and GWS show that AT&T's best nationwide network, accessible on over 20 devices, outperforms our competitors," said an AT&T spokesman. 
T-Mobile's low-band 5G network arrived. And while the speeds were sometimes impressive, often times they were just slightly better than its 4G network.

In 2018, Verizon also played fast and loose with the definition of 5G in its claim to launch the first home broadband service. In truth, the company used a proprietary technology that was very 5G-like, causing rivals to dispute its achievement. It's since vowed to switch over to the industry standard for its home service, but hasn't expanded it. 
In 2019, Verizon talked up 5G UWB, or ultra wideband, its term for really, really fast 5G. (Here's a full list of 5G marketing terms.) But when the service launched in Chicago, testers needed a map to hunt down coverage. It was a mess, although it eventually got better. It plans to hit 30 markets by the end of the year, even if the coverage within those cities is spotty. 
"There were always going to be serious logistical challenges to 5G's deployment here," said IDC analyst Jason Leigh, noting that South Korea was successful. "There was going to be an inevitable letdown." 
Verizon, for its part, acknowledges that it's still early days for the deployment, but that consumers, businesses and governments are excited by the prospect of 5G. Applications like the Disney Star Wars experience, powered by 5G, give you an idea of what's possible. 
"They recognize the impact this network will have," said a Verizon spokesman on the reaction the company's received from its customers and other partners, noting that it's still early days in the 5G roll out. 
This month, T-Mobile and AT&T both launched 5G networks using low-band spectrum, which means way better range. The downside, however, are the lackluster speed boosts. T-Mobile says it gives you only a 20 percent boost in speed over 4G, but covers a wide area. AT&T launched a millimeter wave network a year ago, but still limits it to a closed group of business customers. It says its low-band 5G network offers similar speeds to 5GE. 
Ironically, Sprint, which is saddled with the reputation for poor service, has the most robust network in the few cities it operates in. It's using mid-band spectrum, a sweet spot that gives you a mix of better speed and wider coverage. It's also the type of spectrum that most of the world outside of the US is using. But given its financially strapped situation and the fact that it's waiting for T-Mobile to snap it up, it's hard to seriously consider. 
Globally, we saw similar results our expansive tests. In the UK and Australia, coverage offered big jumps in speeds, but big coverage gaps too. South Korea, however, performed the most consistently. Our overall conclusion: 5G had a long way to go. 

Don't buy a 5G phone

If you were looking at a 5G smartphone this year thinking you were future-proofing yourself, turn around and walk away. 
As mentioned before in numerous CNET stories, buying a 5G phone this year is a bad idea
They're expensive, tend to overheat and suffer from weak battery life. But more importantly, they don't future-proof you for upcoming 5G deployments. 
That's because 5G is a bit more complicated off the bat, utilizing different bands of spectrum. Verizon's 5G UWV uses championed so-called millimeter wave spectrum, which offers tremendous speed and equally tremendously short range. Think a glorified Wi-Fi hotspot with speeds that let you download whole seasons of Game of Thrones in minutes.

As previously mentioned, AT&T and T-Mobile are starting their consumer push with low-band 5G, even if they too have small deployments of millimeter wave networks. Eventually, all of the carriers will start to incorporate low, mid and millimeter wave spectrum when the spectrum becomes available. 
But here's the rub about this year's 5G phones: They're limited in the bands you can tap. So Verizon's Samsung Galaxy S10 5G will get millimeter wave spectrum, but not low band. Or a T-Mobile low-band phone is stuck on that band. 
It's like being stuck in the middle lane of a freeway as faster, freer lanes all around you open up. 

A smoother 2020

As all technologies do, 5G will mature in 2020. Qualcomm has already discussed an integrated processor that includes a 5G modem that will run in more affordable phones. Companies like AT&T and T-Mobile will start building out the different bands of their 5G network. 
Now that 5G networks are live, and the idea of "first" is meaningless, my hope is carriers will just focus on making this work -- for as many people as possible. 
Because despite all my criticism, I do genuinely believe 5G will change the world. I look at how things have changed in the last 10 years since 4G launched, and things are wildly different. The combination of speed and latency from 5G can really enable a lot of new technologies, from remote medicine to self-driving cars
I'm ready for that revolution, even if I have to sit through an early stretch of marketing jargon and unwarranted hype. "

How Your Phone Betrays Democracy

“In footage from drones hovering above, the nighttime streets of Hong Kong look almost incandescent, a constellation of tens of thousands of cellphone flashlights, swaying in unison. Each twinkle is a marker of attendance and a plea for freedom. The demonstrators, some clad in masks to thwart the government’s network of facial recognition cameras, find safety in numbers.

But in addition to the bright lights, each phone is also emitting another beacon in the darkness — one that’s invisible to the human eye. This signal is captured and collected, sometimes many times per minute, not by a drone but by smartphone apps. The signal keeps broadcasting, long after the protesters turn off their camera lights, head to their homes and take off their masks.

In the United States, and across the world, any protester who brings a phone to a public demonstration is tracked and that person’s presence at the event is duly recorded in commercial datasets. At the same time, political parties are beginning to collect and purchase phone location for voter persuasion.

“Without question it’s sinister,” said Todd Gitlin, professor of journalism at Columbia University and former president of Students for a Democratic Society, a prominent activist group in the 1960s. “It will chill certain constitutionally permitted expressions. If people know they’ll be tracked, it will certainly make them think twice before linking themselves to a movement.”

A trove of location data with more than 50 billion location pings from the phones of more than 12 million Americans obtained by Times Opinion helps to illustrate the risks that such comprehensive monitoring poses to the right of Americans to assemble and participate in a healthy democracy.

Within minutes, with no special training and a little bit of Google searching, Times Opinion was able to single out and identify individuals at public demonstrations large and small from coast to coast.

By tracking specific devices, we followed demonstrators from the 2017 Women’s March back to their homes. We were able to identify individuals at the 2017 Inauguration Day Black Bloc protests. It was easy to follow them to their workplaces. In some instances — for example, a February clash between antifascists and far-right supporters of Milo Yiannopolous in Berkeley, Calif. — it took little effort to identify the homes of protesters and then their family members.

The anonymity of demonstrators has long been a contentious issue. Governments generally don’t like the idea for fear that masked protesters might be more likely to incite riots. Several states, including New York and Georgia, have laws that prohibit wearing masks at public demonstrations. Countries including Canada and Spain have rules to limit or prohibit masks at riots or unlawful gatherings. But in the smartphone era — masked or not — no one can get lost in a sea of faces anymore.

Imagine the following nightmare scenarios: Governments using location data to identify political enemies at major protests. Prosecutors or the police using location information to intimidate criminal defendants into taking plea deals. A rogue employee at an ad-tech location company sharing raw data with a politically motivated group. A megadonor purchasing a location company to help bolster political targeting abilities for his party and using the information to doxprotesters. A white supremacist group breaching the insecure servers of a small location startup and learning the home addresses of potential targets.”
