how funny. I just mentioned his tech articles and went back to reading the Chronicle business section and this was what I saw...

AT&T and Verizon wireless customers, listen up. Your world is about to change in the best way.
But to take advantage of that change, it’s going to cost you. If you care about how fast your smartphone talks to the internet, it is going to be worth it. Remember these three words: C-band is coming.
Next week, AT&T and Verizon will switch on new spectrum on their respective networks that will bring their 5G service closer to the hype the telecommunications industry has been churning out for years. It will fill in a big hole in AT&T’s and Verizon’s offerings, and finally make them competitive in 5G with T-Mobile.
This is great news for their customers, many of whom have been wondering why they’re not getting the super-fast speeds they’ve been promised. While C-band will mean a big upgrade in speed, most 5G phones don’t currently support it.
Yep, if you bought a 5G phone in the past couple of years, you’re going to have to replace it to take advantage of what’s coming.
And it’s coming Jan. 19. The rollout of the radio frequencies used for C-band was supposed to happen sooner, but a dispute over airline safety caused a delay. Airliners use C-band spectrum for some altimeters, and the Federal Aviation Administration was concerned 5G would interfere with those instruments.
Telecommunications companies agreed to a delay, and will carve out C-band exception areas around airports, allowing for the start date next week.
For AT&T and Verizon, C-band is critical, a last piece of the 5G puzzle for which the two paid a total of $80 billion in the 2020-2021 auction of spectrum by the Federal Communications Commission.
Currently, those providers only offer 5G service in a low frequency spectrum known as sub-6, and a very high one called millimeter wave, or mmWave. The carriers have a big, national footprint for sub-6, but in most cases, it’s not much faster than LTE. In some instances, it can be slower.
They have a smaller footprint with mmWave, which offers the OMG!! speeds. But mmWave has a hard time passing through objects, even foliage. It has been consigned mostly to open-air locations, including parks, sports stadiums and concert venues.
Verizon also has been building mmWave service out into dense residential areas, including many in inner-loop Houston, for its 5G-based home internet service. C-band will be added to the home service as well.
C-band sits in the middle of the frequencies AT&T and Verizon use, filling a big gap. It promises speeds approaching those of the lower range of mmWave, and significantly higher than sub-6.
T-Mobile, in its acquisition of Sprint, acquired a good chunk of similar, middle-band spectrum and has been hustling to build it out, including in Houston. T-Mobile says its 5G service covers 200 million people in the United States. AT&T and T-Mobile have some catching up to do.
“While T-Mobile has probably the best ubiquitous fast 5G service, its market share of 25 percent still trails both AT&T at 45 percent and Verizon at (29 percent),” said Mark Vena, CEO and principal analyst at SmartTech Research, which tracks consumer tech trends. “To maintain and protect those shares, it’s critical for both AT&T and Verizon to embrace C-band as quickly as possible because it can provide wider coverage and higher speeds.”
Wicked fast
T-Mobile customers with compatible phones have been experiencing impressive speeds with that carrier’s mid-band service. With my iPhone 13 Pro Max, I’ve gotten peak speeds of over 600 Mbps download and 90 Mbps upload in tests when I see the in the phone’s status bar the “5G UC” icon, the indicator that T-Mobile’s mid-band spectrum is in use.
The average is closer to 300-400 Mbps down and 35-50 Mbps up. With its sub-6 5G, speeds range anywhere from the low double digits to over 120 Mbps down, and from 2-25 Mbps up. Clearly, the mid-band makes a huge difference.
What’s even more interesting is that I see decent speeds with just a few bars on the phone’s signal indicator when connected to T-Mobile’s mid-band. With only two bars, I’ve had download speeds in the mid-300s.
So, what can AT&T and Verizon customers in Houston expect when the C-band switch is flipped? I talked to representatives from both carriers to find out.
First, it depends on whether those users own a C-band capable smartphone. Right now, the only compatible devices out of the box are Apple’s iPhone 12 and 13 lineup; Samsung’s Galaxy S21 lineup, Z Fold3 and Z Flip3 and Galaxy A13; and Google’s Pixel 6 and 6 Pro. Other phones may be capable with a software upgrade, but neither AT&T nor Verizon spokespeople would name them.
Those with capable phones should see indicators in the devices’ status bar at the top of the screen. AT&T users will see “5G+”, the same designation for its existing mmWave service. Verizon users will see “5G UW” (UW is UltraWideband), also the carrier’s signifier for mmWave.
Owners of C-band-capable phones will see noticeably faster speeds. Verizon says to expect outdoor downloads approaching or exceeding a gigabit per second, with indoor speeds around 300 Mbps or better. An AT&T spokesperson didn’t not provide specific speeds, but analysts expect them to be comparable to Verizon’s.
Neither carrier will charge extra for C-band access. That said, you need to be on one of the carriers’ unlimited plans to get access to 5G of any flavor.
Cloud in silver lining
That’s the good news. Here’s the bad.
A lot of early adopters, hungry for AT&T’s and Verizon’s promised high-speed nirvana of 5G, went out and bought 5G phones in the past two years. Those early handsets don’t work with C-band. To get access to those speeds, they’ll need to buy a new phone. (Pro tip: When looking at the detailed specifications for a smartphone, check to see if it supports the band designated as N77.)
I asked both carriers’ representatives if there would be some kind of trade-in or upgrade deal. Verizon left open the possibility, saying that, “historically” the company has had “enticing offers” around 5G phones. AT&T has an existing trade-in program.
But analyst Vena says that AT&T and Verizon are going to want to get customers onto C-band as soon as possible, which means deals on compatible phones will abound.
“We might see a level of carrier subsidization for new smart-phones that we haven’t seen in years,” he said. dsilverman@outlook.com twitter.com/dsilverman
