Cutting Through Bullshit Around 5G Latency

There’s a lot of unrealistic hype going around about 5G. Most of the hype focuses on the blazing-fast speeds 5G can offer.

Today, T-Mobile’s CEO, Mike Sievert, made a big deal about 5G latency rather than 5G speed:1

Latency measures the time delay involved in data transfer. It’s common for 4G connections to have a latency of about one-twentieth of a second (50 milliseconds). Some 5G technologies may be able to push latency far lower.

The video Sievert shared is allegedly a demonstration of latency under different technologies. It’s not remotely fair. The phone supposedly demonstrating a 4G LTE connection is about five seconds behind the real world. Latency isn’t anywhere near that bad with 4G. If it was that bad, normal voice conversations and video chats using 4G wouldn’t be possible.

Rethinking “Nationwide”

T-Mobile and AT&T started describing their 5G networks as nationwide once the networks covered over 200 million people. I’ve seen multiple people suggest that this is related to FCC rules. Allegedly, the FCC only allows networks to be described as nationwide when they cover over 200 million people. I’ve searched around, and I can’t find any FCC documents mentioning such a guideline.

As far as I can tell, the 200 million number comes from the National Advertising Division (NAD), a self-regulatory body for the advertising industry.1 Here’s an excerpt from a 2014 NAD publication:

NAD noted in its decision that it has applied a consistent standard for ‘coast to coast’ service for the past 10 years. In general, a wireless network can claim to be nationwide or coast to coast if the provider offers service in diverse regions of the country and the network covers at least 200 million people.

200 million people would make up about 60% of the U.S. population.2 I don’t think a network covering 60% of the U.S. population is nationwide in the common-sense meaning of the word. If networks with such lackluster coverage are advertised as nationwide, consumers will be misled.

The NAD should update its approach. The exact meaning of nationwide isn’t clear cut, but I think even a loose standard should be something like this:

Nationwide network: A network that covers at least 85% of the U.S. population and offers service in some parts of every state.

The NAD should probably frame its standard in terms of a percentage of the U.S. population covered (rather than a raw number of people covered). In 2004, 200 million people would have been almost 70% of the U.S. population.3 The NAD’s standard made more sense then. As the country’s population has grown, the NAD’s standard has become weaker.

AT&T’s 5G Coverage Now “Nationwide”

This morning, AT&T announced that its 5G network is now nationwide. By “nationwide,” I believe AT&T means that the service is estimated to cover over 200 million Americans. There are still plenty of parts of the country that are not covered by AT&T’s 5G service.

AT&T shared a few other noteworthy items in its announcement:

  • AT&T will add 5G support to the Unlimited Starter plan (the carriers’ most basic postpaid unlimited plan) at no extra charge on August 7.
  • Business customers on the Unlimited Web-Only plan will also get 5G support starting on August 7.
  • Cricket Wireless will begin offering 5G service on August 21.

On all of these plans, 5G service will only be available for subscribers with 5G-compatible devices.

5G Coming To Cricket Wireless

Today, AT&T came out with a press release stating that 5G service will be coming to Cricket Wireless. Here’s the relevant bit:

On Aug. 21, Cricket Wireless customers will be able to activate 5G service on the Samsung Galaxy S20+ 5G. More details soon!

As far as I can tell, Cricket has not yet updated its own web pages about 5G.

I expect Cricket subscribers will be able to access both AT&T’s sub-6 5G and AT&T’s ultra-fast millimeter wave 5G. While the S20+ will initially be the only 5G phone offered by Cricket, we should soon see the carrier offering more 5G-compatible devices. It may also be possible for Cricket customers to bring their own unlocked 5G phones to the service.

Verizon’s 5G Mobile Hotspot & Tethering Policies

Verizon’s higher-end unlimited plans come with monthly allotments of full-speed 4G hotspot data.

  • Play More Unlimited – 15GB
  • Do More Unlimited – 15GB
  • Get More Unlimited – 30GB

Subscribers that burn through all of their full-speed 4G data can continue to use more hotspot data with a 4G connection throttled to a sluggish 600Kbps speed.

Verizon doesn’t prominently advertise it, but the company has separate policies for 5G hotspot data. Here’s a bit from a section of Verizon’s website that gives additional details about one of the carrier’s unlimited plans:1

Unlimited 5G Ultra Wideband Mobile Hotspot

An unlimited 5G Ultra Wideband mobile hotspot means your smartphone becomes an ultra-fast and reliable Wi-Fi connection for your other devices. Service available in select locations and requires a 5G capable device.

Yesterday, I was exploring my Verizon online account for the Play More Unlimited plan and found this:

Screenshot of Verizon account interface showing a 5G hotspot allotment

Verizon is currently allowing 50GB of full-speed 5G hotspot use each month on the Play More plan. After 50GB of use, speeds are throttled to 3Mbps. While 3Mbps isn’t a great speed for hotspot use, it’s still fast enough that most people could browse the internet and do work on a laptop without overwhelming frustration.

I’m guessing the Do More and Get More plans have the same 50GB allotment, but I’m not sure. It’s odd that Verizon’s 5G hotspot allotment on the Play More plan is so much larger than the regular (4G) allotment.

I wonder if the large allotment is a promotional thing. Will we see the allotment shrink as more subscribers get 5G-compatible phones?

Post publication update: As of January 1, 2021, Verizon appears to have dropped the data cap and throttle for Ultra Wideband hotspots.

Opensignal’s Report on U.S. 5G Performance – No Big Surprises

Earlier this week, Opensignal released a report on the performance of 5G networks in the United States. Opensignal’s report puts some numbers and data behind two things that were already clear:

  • T-Mobile is destroying the competition in terms of 5G coverage, but T-Mobile’s 5G isn’t very fast
  • Verizon’s 5G is outrageously fast, but the coverage profile is terrible.

Opensignal primarily collects its performance data by crowdsourcing data from tests that run in the background on regular people’s phones. It looks like the company restricted the data underlying this report to include tests run from 5G-compatible phones.

Speeds

Verizon destroyed the competition with an average 5G download speed of 495Mbps. The other major networks in the U.S. had 5G download speeds averaging around 50Mbps. Verizon’s dominance in download speeds is due to the company’s focus on rolling out millimeter wave 5G.

Coverage

Unlike Verizon, T-Mobile has focused on deploying sub-6 5G. This type of 5G is great for covering large areas, but less impressive for delivering high speeds. Unsurprisingly, T-Mobile dominated in terms of 5G availability. According to Opensignal’s data, T-Mobile subscribers were able to access 5G 22.5% of the time. Verizon did about fifty times worse with an availability score of 0.4%.

While 0.4% is low, it’s still a better availability score than I would have predicted for Verizon. I wonder if Opensignal’s crowdsourcing approach might lend Verizon’s availability scores a leg up. If living near a Verizon 5G deployment makes a Verizon customer more likely to purchase a 5G phone, selection bias can creep in and cause Opensignal to overestimate Verizon’s actual 5G availability.

Silly press releases

Following Opensignal’s release of its report, T-Mobile published a press release. The company bragged about the network’s excellent 5G coverage without mentioning that the network got demolished in the download speed results.

Verizon published its own press release bragging about ludicrous download speeds. Verizon’s awful 5G availability score was not mentioned.

Download Speed Experience – 5G Users

Opensignal’s report included a metric called Download Speed Experience – 5G Users. The results for this metric were calculated by looking at users with 5G-compatible phones and tracking their average download speed even at times where they did not have 5G connections. In some sense, this single metric does some accounting for both 5G speeds and 5G availability.

Verizon and AT&T tied for the top spot:

The metric is interesting, but I don’t think it quite captures how users will feel about the quality of their download speed experiences. The marginal value of a 10Mbps boost in download speeds that moves a subscriber from 5Mbps to 15Mbps is much greater than the marginal value of a 10Mbps boost that moves a subscriber from 500Mbps to 510Mbps. Collapsing a distribution of download speeds into a single, average download speed masks this reality.

5G+ Brilliant Marketing From AT&T?

A while back, AT&T began calling some its 4G service 5GE. It tricked consumers into thinking they were getting 5G when they weren’t. It was bullshit.

Now, AT&T is calling its millimeter wave (mmWave) service 5G+. In some ways, the 5G+ label could confuse consumers. Verizon’s 5G service uses pretty much exclusively mmWave right now. Verizon doesn’t call its mmWave service “5G+.” To Verizon, mmWave is just “5G.”

Still, I’m not annoyed by AT&T’s 5G+ branding. Not all 5G is the same. Lower frequency, sub-6 5G, is typically way slower than mmWave 5G. Laypeople don’t realize how different sub-6 5G is from mmWave 5G. If we want consumers to understand the difference, carriers need to help make that happen. Calling sub-6 service “5G” and mmWave service “5G+” makes a clear distinction for consumers.

Samsung Galaxy S20 5G UW’s Mislisted & Different Specs

Verizon just released the Samsung Galaxy S20 5G UW. While other carriers had already released versions of the S20 5G, Verizon’s UW (ultra-wide band) model of the phone is the first version compatible with Verizon’s millimeter wave 5G service.

I pre-ordered the phone. The device I received does not have the specs Samsung advertised. Here’s an archived Samsung web page with the specs as of June 2. Here’s the page as of today, June 9.

No SD Card Slot

Unlike other models of the S20, Verizon’s UW model doesn’t have an SD card slot. Those who pre-ordered the phone couldn’t have figured that out from the information on Samsung’s website.

The June 2 specs page shows an SD slot:

Mention of the SD slot is dropped in the newer, corrected version of the page:

The listing for the phone on Verizon’s website is getting a lot of one-star reviews from pre-order customers annoyed about the missing SD slot.

Missing network bands

I like it when phones have extensive cross-network compatibility. I was pleasantly surprised when I saw Verizon’s S20 5G would be compatible with band 71 (a low-frequency band T-Mobile uses extensively). Here’s a screengrab from Samsung’s early specs page:

Originally listed bands for S20 5G UW

It turns out the phone doesn’t support band 71 (or bands 1, 29, and 30). Here’s the updated specs page:

Less RAM than other carriers’ models

Verizon’s version of the S20 5G comes with 8GB of RAM. Samsung listed this correctly on the early specs page. Other carriers’ versions of the S20 5G come with 12GB of RAM. For most users, I expect the reduced amount of RAM in Verizon’s model won’t cause performance issues.

AT&T Drops 5GE Ads & Keeps 5GE Icon

For a while now, AT&T has been misleadingly labeling some of its 4G services as “5GE.”

A self-regulatory body in the advertising industry recently concluded that AT&T should stop mentioning 5GE in advertisements:

A panel of the National Advertising Review Board (NARB) has recommended that AT&T Services, Inc. discontinue its ‘5G Evolution’ and ‘5G Evolution, The First Step to 5G’ claims…the NARB panel determined that both claims will mislead reasonable consumers into believing that AT&T is offering a 5G network and recommended that the claims be discontinued.

AT&T agreed to cease advertising 5GE, but the carrier will continue to show the 5GE icon on phones. As a result, AT&T has been receiving well-deserved scorn from journalists.

AT&T’s actions aren’t surprising. I don’t think the National Advertising Review Board has much power to change business practices outside of advertising. Further, AT&T has tricked some subscribers into thinking their 5GE connections are actual 5G connections. If AT&T stopped showing the 5GE icon, the carrier would have to deal with complaints from frustrated customers thinking they lost 5G access.

Xfinity Mobile Updates: 5G, Pricing, and Prioritization

Today, Xfinity Mobile released a handful of changes.

5G Support

Xfinity Mobile now officially offers 5G powered by Verizon’s network. The carrier’s updated network webpage has a lot of content devoted to the wonders of 5G.

Pricing

The 1GB by-the-gig plan has increased from $12 per month to $15 per month. Data add-ons for by-the-gig customers have also increased in cost from $12 per GB to $15 per GB.

The 3GB by-the-gig plan for $30, the 10GB by-the-gig plan for $60, and the $45 per line unlimited plan are still available with unchanged prices.

Prioritization and video throttling

With the last generation of Xfinity Mobile plans, subscribers were typically subject to deprioritization during congestion. It looks like subscribers on the new by-the-gig plans will not be subject to deprioritization. Here’s a screenshot from my within my Xfinity online account:1

Screenshot suggesting Xfinity Mobile is offering better prioritization on by-the-gig plans

As far as I can tell, subscribers on Xfinity Mobile’s Unlimited plan will continue to be deprioritized during periods of congestion.

Optional opt-in

Existing subscribers are not being forced to switch over to Xfinity’s new plans. At the moment, it looks like subscribers who don’t switch over will continue to experience the old price structure while missing out on new perks like 5G access.

I’m unsure whether Xfinity Mobile will let subscribers stay grandfathered on the old plans indefinitely. It’s possible subscribers will eventually be forced to switch to new plans.

My take

As an Xfinity Mobile affiliate, I got a heads up that changes were coming. It sounded like there would be a price increase on the 1GB plan, and I figured I wouldn’t be able to recommend Xfinity Mobile as strongly after the changes. I’m happy to say my expectation was wrong. The $3 increase in the 1GB plan isn’t too substantial, and the improved prioritization for by-the-gig customers is great.

I’m frustrated by how actively Xfinity Mobile is marketing the new 5G service without making it clear that (a) Verizon’s 5G coverage is extremely limited and (b) few consumers have devices compatible with Verizon’s 5G. That said, Xfinity Mobile’s marketing is less misleading than what we’re typically seeing from carriers offering 5G. While the new 5G access won’t have a meaningful effect on most subscribers today, it will become more important as Verizon expands its 5G coverage.
