You see, AT&T is promising to launch real 5G NR cellular
in 12 cities by the end of 2018, mere weeks from today. But despite
that fact — and a variety of promises, milestones, and one-off
demonstrations from other carriers which plan to launch as soon as early
2019 — we still don’t have a clear idea of what 5G will actually offer
right away. Few journalists have even so much as touched a 5G device.
That will change next week. AT&T and Verizon tell The Verge
they’ll have live 5G networks in Maui at Qualcomm’s big event, and
we’ll be able to try a real, 5G-enabled phone and a pocketable 5G mobile
hotspot for the first time.
Qualcomm will also reveal a new Snapdragon processor
designed to appear in actual 5G phones, and a “Snapdragon 1000”
processor for a new wave of always-connected Windows laptops. (Maybe, after a decade and numerous attempts, Qualcomm will finally demo a smart-book
worth buying.) Qualcomm will attempt to use the rising wave of 5G hype
to help raise the profile of its new chips — and make the case that the
two are potentially connected.
After speaking to executives from Qualcomm, Verizon, and
AT&T, we’re getting a far clearer picture of what they hope 5G will
offer on day one, even though an awful lot of key details are still up
in the air.
The timeline: Don’t expect phones yet
Even if AT&T launches a 5G mobile network by the end of the year — AT&T said “in the next few weeks” over five weeks ago,
and it’s sticking by “end of the year” as of today — you won’t just be
able to run out and buy a 5G phone. The only confirmed device so far for
AT&T’s network is the chunky Netgear Nighthawk 5G Mobile Hotspot, and AT&T tells us that the so-called “puck” will be its only 5G device available at launch.

Verizon will technically have a phone when it launches
its 5G offering in early 2019, but only kind of. If you buy the
existing, Verizon-exclusive Moto Z3 — let’s just say it’s not our top pick today
— Verizon says its first 5G device will be a magnetic, modular 5G Moto
Mod attachment you can snap onto that phone to add speedy 5G NR
connectivity, too. Verizon says we'll get to try the 5G Moto Mod in Maui
as well.
If those aren’t your cup of tea, you’ll probably be
waiting until Q2 2019 at the earliest. That’s when Qualcomm president
Cristiano Amon expects the first real wave of smartphones to arrive.
”We are working, so as early as the second quarter of
2019, you’ll have smartphones being launched across the United States,
across Europe, across South Korea, Australia. Some early in the quarter,
some later in the quarter... they’re all going to be Android flagship
devices,” says Amon. “You go to CES [in January], you’ll start to see a
lot of phone announcements; you go to MWC [in February], you’ll see a
lot of actual phone launches.”
You’ll note that Qualcomm’s president says “Android,” not Apple — rumor is Apple won’t release a 5G iPhone until 2020.
That shouldn’t be much of a surprise, considering how the original
iPhone didn’t yet have 3G, and the iPhone 4S didn’t add LTE, even though
both were available in competing phones at the time.

If that sounds like a slow start for mobile 5G, know that
LTE had a similarly slow launch, even if in hindsight it seems like it
was faster. Verizon’s LTE network went live in December 2010, but those
once-amazing speeds were only available to people who plugged giant dongles into their PCs
until the first Verizon LTE smartphone launched in March 2011.
(MetroPCS managed to get its first LTE phones out a bit more quickly.)
At least this time, one 5G standard — known as 5G NR and created by the GSMA
— has practically everybody on board. Back in the day, AT&T,
T-Mobile, and Sprint were trying to push HSPA and WiMax as their LTE
alternatives. But even Verizon, which originally promoted and has already deployed the competing 5G TF standard to deliver wireless internet to homes in four US cities,
says all of its future deployments will be on 5G NR instead, and that
5G TF was just a way to push the industry to quickly adopt an actual
global standard. For all they knew, 5G TF could have been it.
“The game was always the standard standard,” says Nicki Palmer, Verizon’s chief network officer.
So it doesn’t look like we’ll have a 5G standards war — at least not yet.
5G is starting slow by starting fast
“We need to
build a crescendo,” says Amon. Qualcomm obviously has a vested interest
in making people believe that 5G is actually meaningfully better than
the cell connections we already have now. “You’re not going to change
your phone unless the battery life is higher, the form factor is
attractive, and you need companies that can actually deliver the
performance,” he says. (Early LTE devices were notoriously thick and
drained batteries quickly.)
That’s why, even out of the gate, he says 5G will be
dramatically faster and dramatically more responsive, to the point that
bandwidth-sapping uses like streaming video will feel effortless.

“Today you stream music everywhere. You don’t download
music anymore; even if you have low coverage, you have enough quality to
stream music. 5G will do that for video,” Amon says, before moving on
to fancier, further-out predictions like unlimited storage and on-demand
processing power from the cloud that can, he imagines, virtually cram
the power of a Magic Leap-like augmented reality headset into a normal
pair of glasses.
High-flying promises of fast internet and cloud
connections are nothing new, but historically they have always crashed
into the reality of actual network performance that doesn’t live up to
them. And the way that Qualcomm, AT&T, Verizon, and others hope to achieve the performance out of the gate may mean a slightly different, spottier network than the ones we’re used to right now.
AT&T and Verizon both say they’re exclusively rolling out millimeter wave (mmWave) radios, which inherently provide far
more bandwidth and capacity than today’s networks. But at 39GHz and
28GHz, those millimeter wave signals also don’t travel as far or
penetrate buildings as easily as conventional cellular. That means
you’ll probably drop down to LTE speeds when you transition indoors, and
in order to cover the same area as today’s LTE cell towers, carriers
will need to provide many more smaller cell sites. AT&T says it’s
focusing on outdoor cells first, but is also looking at indoor ones for
public venues like stadiums and concert halls.
:no_upscale()/cdn.vox-cdn.com/uploads/chorus_asset/file/13592292/Qualcomm_5NR_Preso_spectrum.jpg)
5G NR does have a solve for wider coverage, too: “sub-6”
spectrum, meaning radio frequencies below 6GHz, which include everything
from traditional WI-Fi (2.4GHz, 5GHz) down to the decently
building-penetrating 700MHz frequency that AT&T, T-Mobile, and
Verizon use for a large portion of their LTE networks today. (T-Mobile
recently added some 600MHz as well.)
But AT&T and Verizon say they aren’t prioritizing
sub-6 5G quite yet, partly because the carriers don’t have enough
spectrum at lower frequencies to wow with speed. “With a 20MHz band of
600MHz [spectrum], you’re not going to get that lift. You’d have to ask
yourself what’s different, what does 5G really mean,” says Verizon’s
Palmer.
It also might be partially because sub-6 smartphone chips may not be ready yet, at least for the particular spectrum pairings
that US carriers currently use. “The FDD, which is what the bulk of
operators have ... the silicon to support that FDD spectrum doesn’t
become available until later in 2019,” says Gordon Mansfield, AT&T’s
VP of converged access and device technology.
The upshot? Instead of promising to launch their 5G NR
networks in entire cities at once, AT&T has only committed to
bringing 5G to unspecified “parts” of the 19 locations it’s named so far,
and the fastest forms of 5G may never cover every person. “Our ambition
is large... that doesn’t mean we’re going to blanket every corner of
the country with millimeter wave,” says Palmer, adding that she will
“most likely” start in areas with the most traffic and demand, too.
T-Mobile says it will have a nationwide 5G network in 2020, but it's not
clear how much of that will be millimeter wave and how much sub-6. It's
using both.

None of this means your device will just drop off the
network when you’re out of 5G range, though. AT&T and others say
they are building their 5G NR tech on top of existing 4G LTE to start.
Your devices will be connected to both LTE and 5G NR simultaneously and
switch between them seamlessly, says Mansfield.
Plus, both AT&T and Verizon expect current LTE
networks to get faster as 5G rolls out — partly because people moving to
5G will free up room on the LTE networks, partly because of all the
underlying infrastructure improvements the carriers are making to ensure
their 5G networks will be faster, and partly because we still haven’t
reached the limit of what LTE can do. AT&T even launched a fake 5G network called “5G Evolution” last year
to show off how existing LTE Advanced and LTE Advanced Pro techniques
could reach theoretical download speeds of 400Mbps. (Other carriers
rolled out those techniques even earlier, though.)
TL;DR: not all 5G will be equal, the
faster flavor of 5G will come first but it’ll be spotty, and the rest of
the time you’ll probably be surfing on LTE. But at least it could be
faster LTE than you’re getting today.
Nobody’s talking pricing, speed, unlimited, or data caps
When it comes
to cell phone plans, 2018 is the year the word “unlimited” lost all
meaning, as marketers realized they could twist it however they like.
Verizon now has three unlimited plans! And every unlimited plan has limits.
So consider me a wee bit concerned that on the eve of AT&T’s launch, neither AT&T nor Verizon was willing to talk about how much, how often, how fast,
nor answer what’s probably the most burning question: whether we should
expect to pay more, less, or the same for 5G connectivity. (Because
5G’s inevitable, right? You’ll be paying for it sooner or later.)
For that matter, neither carrier would even tell me
whether today’s data caps might get larger to account for the tremendous
amount of data we’ll supposedly be using on 5G. I figured that would be
a softball question, but they deflected anyhow.
:no_upscale()/cdn.vox-cdn.com/uploads/chorus_asset/file/11603635/Screen_Shot_2018_06_26_at_12.19.27_PM.png)
“5G ushers in a new era of how to consume wireless
services,” Palmer told me, pointing out that alternative business models
might make sense for, say, a 5G cloud gaming service. “You as a customer would purchase that in a different way.”
“Is it the cost of one device or the fact you’re
connecting many devices? We have to look,” says Kevin Petersen,
AT&T’s SVP of wireless product marketing.
I don’t know if these thoughts are code for “5G is
expensive and we need to defray the cost,” whether these carriers just
haven’t figured out pricing yet, or whether they don’t want to tip their
hands early, but we’re getting down to the wire — especially for
AT&T’s promised end-of-2018 launch.
And I do wonder how the death of net neutrality
will embolden the carriers to do things that would have been
unthinkable before. One of the reasons carriers argued for the end of
net neutrality was to open up “innovative” business models, and it’s
possible they’ll look at bundling their own services, or those of
partners, with free or discounted 5G connectivity.
Lastly, I thought it was especially weird that Verizon
wouldn’t talk about what kind of speeds we can expect from 5G,
considering Verizon said months ago that its 5G Moto Mod would produce
download speeds of up to 5Gbps, and AT&T recently told us we should
see at least gigabit speeds. When I went back to look at Motorola’s 5G Mod website, I noticed a discrepancy: the fine print at the very bottom of the page says that we should expect peak
download speeds of more like 300–500Mbps. That’s still fast, but it’s
not really 5G. I pinged Verizon last night to ask about that, and I’ll
let you know what I hear.
I suppose it won’t be long until I’m standing on a tropical island measuring speeds for myself, though.
Let’s talk chips
Maui won’t just be about data speeds. 5G is just one of the topics Qualcomm intends to touch on.
Amon confirmed to The Verge that it’s where
Qualcomm will launch its next flagship Snapdragon processor for 5G
devices, and he also namedropped a separate “Snapdragon 1000” chip for
always-connected ARM-powered PCs — a processor rumored to finally be
powerful enough to challenge Intel’s Y and U-series CPUs in ultrathin
laptops and 2-in-1s.
We won’t get details until next week, but Maui is an
important moment for Qualcomm. Apple seems to be getting stronger every
year, while Intel is definitely not. Apple’s own processors are getting
so fast, so quickly, that an iPad Pro could arguably beat a new Intel-powered MacBook in raw speed, and the rumors that the Mac will ditch Intel chips for Apple’s own ARM processors are starting to make an awful lot of sense.
:no_upscale()/cdn.vox-cdn.com/uploads/chorus_asset/file/2430006/snapdragon-eye.0.jpg)
If true, Qualcomm will want to have a rival laptop chip,
and that means showing it can actually provide enough performance to
make Windows laptops and tablets worth buying. Amon agrees that wasn’t
true of the disastrous Windows RT, and I’d argue it wasn’t true of the Snapdragon 850 laptop chip that Qualcomm released last year, either (read our Samsung Galaxy Book 2 review), but maybe this time will be different?
Amon
says the “Snapdragon 1000” will support more memory, which is a big
deal all by itself — the Galaxy Book 2’s 4GB didn’t feel like enough for
Windows.
But Qualcomm’s president also hints that Maui won’t be
all about CPU performance, because in his view, 5G connectivity makes it
less important how much computing power you can fit in your pocket or
shoulder bag, and because more and more key smartphone features (machine
learning, image processing, graphics, etc.) are no longer primarily
handled by the CPU. “Apple has achieved remarkable single-threaded CPU
performance,” he says, “but ask yourself if the most important thing on a
processor is the single-threaded CPU performance?”
There’s some truth to that, but the idea that 5G is
suddenly going to turn your ARM-powered mobile chip into a supercomputer
is quite a stretch — and it’s hype we’ve heard before. LTE was also
supposed to provide low enough latency for on-demand processing, but
splitting a processor load between a local device and a remote server
has proven a pretty tough business so far. (The first generation of
cloud gaming companies got absorbed by Sony instead of prospering on their own, and Sony’s service recently added an option to just download the games instead of streaming.)
And it’s really not a great argument for a Windows
laptop, where raw local performance is key. Plus, winning over Windows
users will mean figuring out some lingering app compatibility issues.
“Windows RT was a big disaster because you have no apps,” Amon recalls.
That’s not quite the case anymore now that Windows on ARM supports
“legacy” x86 apps to a degree, but he also believes that demand for
those legacy apps is shrinking as more people use a phone as their
primary computer. Amon argues that if what people want from a laptop is
mobile apps on a larger screen, Qualcomm already has enough processing
power.
Clearly there’s going to be a lot of hype to unpack in
Maui, both in terms of what 5G can actually deliver — when, where, how
much — and in terms of whether Qualcomm’s new processors will make the
first wave of 5G devices feel like a huge upgrade instead of a beta test
for people with money to burn. I fondly remember bragging about the blazing speeds I saw with my first 4G LTE dongle, but the early phones were a bit of a mess at launch.
But there may just be enough new tech
here to justify a bit of hype. I light up every time I imagine a
wireless connection that could totally wipe the floor with the
landline service I have at home. That’s the feeling that Qualcomm,
Verizon, and AT&T are trying to foster. Now they just have to prove
they can make it real.
