Something I've noticed is that a phone is actually usable at a stadium or concert when 3g or 4g felt essentially useless at that density.
reply
I've seen an interesting corollary: 4G on an airplane at the gate is much faster than the 5G microcells inside the terminal.

If I'm downloading podcasts for a flight, I do it on WiFi beforehand or on 4G on the plane. 5G in the terminal is really useful at getting you some service, but it's slow.

Probably a side effect of not enough backhaul speed.

That has not been my experience at all although that’s just another anecdote.

I thought that's why many large venues offer free WiFi.

5G outperforms wifi in crowded situations. With wifi you get increasing collisions and backoff intervals until everything stalls; with 5G you just get less bandwidth (time sliced) but no collisions, and its frequency spectrum is free of interference.

AT&T has figured out a way to monetize that. If you have a "Turbo" plan or add-on, your phone will work in crowded cells.

If you don't, good luck with that.

Net neutrality would have prevented this kind of pay to win
reply
How would it have helped? Net neutrality doesn’t mean you can’t sell your customers different bandwidth guarantees.

Net neutrality is only about the connections between a provider and external networks, not about how a company handles bandwidth contention amongst its customers.

Net neutrality would fix a problem like “only Facebook is accessible inside crowded stadiums” not “AT&T customers who pay more get better connections in crowded stadiums”

reply
Net neutrality as generally understood says nothing about being able to pay more for a higher service tier from your ISP.

It's entirely on the publisher side: net neutrality was an attempt to avoid ISPs getting paid extra---costs that would be passed onto you---in exchange for making your experience on site A be better than your experience with site B (or service, vs site).

Think: "Oh, yeah, Netflix 4k works great on your new Comcast plan! But if you want Hulu 4k, you're gonna need to pay us more, because Netflix pays us to make their shit work better than Hulu's if you don't!"

reply
Net neutrality was just big companies like Google trying to get free bandwidth for things like YouTube which saturate all their peers.

Think about it, when’s the last time you saw a funded campaign for something that was actually good for us? When’s the last time you saw Google campaigning for privacy?

reply
People still believe this? Google pays their ISP. I pay my ISP. Google does not pay my ISP. Why is my ISP's response to the amount of traffic I use demanding to bill someone other than me?

To be clear, Google was doing this out of self-interest. Paying user ISPs for access to those users is not a cost they want to pay. But it's the same as any other protection racket. A local shopkeeper has personal reasons to not want to pay off the mob, but that doesn't mean their position is wrong.

reply
ISP's spent $$$$$ against net-neutrality cause they wanted to get paid twice (Google already was paying for their side of the bandwidth as the source).

When you add the second line---pretending that that nobody funding all the anti-net-neutrality let-big-ISPs-do-what-they-want stories that pro-legacy-company Republicans ate up---it makes me think this is some astroturfing, since it goes from "maybe this person fell for the ISP claims" to straight-up dishonest intentionally-misleading-fallacy.

Google was obviously on the side of "don't get charged twice" but ultimately net-neutrality was a tech enthusiast consumer position that came out of a desire to avoid getting charged more on the basis of what sites you did or didn't want to watch, and ISP's trying to influence where you visited by cutting deals to get paid to prioritize A vs B.

(Hell, ISPs were already getting paid "twice" for the bandwidth in some ways, e.g. when your "100Mb" plan only works at that speeds if your neighbors aren't using it much. That's a different sort of incomplete-advertising trickery that helped create the whole "too many people using Youtube are saturating the network!" "problem" in the first place.)

(And high-bandwidth publishers already were making private peering/colo-of-servers deals with ISPs and CDNs that I don't believe would've been prohibited by net neutrality, so the 'protection racket' aspect of the ISP's game was maybe more arguably wanting to be paid thrice? Or wanting to be paid without providing that colo service?)

4G used clever ideas to get much better practical spectrum efficiency than people thought was possible... At the cost of very expensive infrastructure. The biggest selling point to carriers was standalone 5G networks that were cheaper to build but paradoxically carriers are prone to frame 5G as a feature customers pay more for.

The area where wireless networks fall short is coverage. Obviously many homes and businesses are difficult to cover with wireless technology. Also many "IoT" and public service situations need wide coverage, and a network that works in 92% of places is "close but not cigar." There are few obvious answers rather than "lots of fiber and very cheap small cells" and "satellite technology" but it's what it takes to address wireless use cases that currently aren't addressed.

reply
This doesnt seem to match reality?

e.g. Notably several major carriers in India skipped 3G entirely and went to 4G directly because it was cheaper per subscriber. Which implies less expensive equipment per unit performance?

reply
Most of what passes for 5G in the US is the same old but full duplex with wider channels.

Calling that 5G obscures the fact that millimeter wave 5G standalone is a totally different beast, and a huge network engineering challenge.

It may seem bureaucratic to regulate what people can call 5G, but US consumers get ripped off thinking they're on an advanced network when in fact you could call it the long-term evolution (see what I did there?) of the existing network.

reply
5G mm is vaporware. Virtually no one uses it (especially globally) and it is expected to be stripped out within a generation or two.
reply
sure but is anyone deploying mmwave outside of maybe sports stadiums? I'm not exactly going to get it on my commuter train or at work.
reply
I get 5G mmWave in my home and around my neighborhood in Seattle. In fact sometimes at home I’ll turn off WiFi on my phone just because I’m sitting in a WiFi dead zone but the mmWave still works great.

This is on Mint Mobile, a budget MVNO now owned by T-Mobile. I pay $20/month for 15GB data.

reply
You're probably not getting mm wave with Mint. T-Mobile hasn't deployed mm wave much. They have deployed a lot of 2.5GHz spectrum which will be very fast (faster than most people's home internet connections). If you're seeing 5GUC, that's probably not mm wave.

I think a lot of people are attributing speeds of 200-700Mbps to mm wave when it's actually pretty ordinary speeds for 2.5-5GHz coverage today now that carriers have decent capacity there. If you're getting below 144Mbps, you're in the bottom 25% of T-Mobile's network experience. Over the past 6 years, speeds have gotten a ton faster, mostly from 2.5-5GHz spectrum. Verizon is the only carrier that put much effort into mm wave and it still covers basically nothing.

Ignoring latency, you're likely to get speeds similar to wifi from today's mobile networks without mm wave - unless you have a really great home internet connection and a good wifi setup. I have a MacBook Pro, but it only has wifi 6 and I can get 700-800Mbps out of my wifi, but I'm not getting 2Gbps from it.

reply
You're ripping yourself off, you can get 1TB of 5G from tmobile for $50-60
reply
How is paying $20 instead of $50-60 ripping themselves off? Have you considered that the extra 985GB might be useless to them?
reply
Imagine taking the time to respond like this.
reply
I'm paying $15/mo. To pay $50/mo for in the end the same thing (I'm going to use the same amount of data regardless) just means I'm spending $420 a year more for the same outcome.

How is it a better deal to spend more money for essentially the same thing?

Imagine you're buying food that will go bad tomorrow. You can't keep it. You can't share it. You can buy enough food to fill you up today for $5, or enough food to fill you up 50x for $20. You will still eat that one unit of food, the other 49 units will just go to waste. Which do you buy?

For all the time I've had Mint, I've saved nearly $3,000 compared to your $50/mo plan. I've never felt the urge to really need more data personally, and it's worked well for me on my international travels around North America. If the outcome was the same, wouldn't you rather keep $3k in your pocket?

reply
is anyone deploying mmwave outside of maybe sports stadiums?

I have it in my home, but I live in the center of a major city. It just speedtested at 476.64 Mbps down, though I think I've seen 650+ in the past, but I might be mis-remembering that.

However, I only get 5G mmwave (indicated as "5GuW" on the phone) on my work phone.

The carrier I use for my personal phone charges an extra $20/month for 5G, and I don't care that much, so I leave it at 4G LTE.

Edit: Just re-tested and got 767 Mbps.

reply
5GUW on Verizon isn't necessarily mm wave. Originally, it meant mm wave, but that hasn't been the case since 2022. Now it means the 3-5GHz C-Band spectrum or the 20-50GHz mm wave. If you're seeing 5GUW on your phone, it's going to be C-Band a lot more than mm wave.

C-Band spectrum also makes sense given a speed test of 400-800Mbps. That's fast, but not hugely faster than what you should expect with really good coverage today. T-Mobile experiences speeds above 560Mbps 25% of the time. Verizon's 5GUW (which is mostly C-Band) experiences speeds above 620Mbps 25% of the time. You ran two speed tests and got 477Mbps and 767Mbps. One of those is pretty average for C-Band and one of those is quite good for C-Band (25% faster than the 75th percentile), but nothing too out of the ordinary.

Those are speeds that are relatively common when carriers have around 150MHz of 2.5-5GHz spectrum deployed in your area and you have good signal and not too much congestion.

mm wave does exist, but the coverage is often a block or two with indoor coverage being really spotty. C-band coverage will be measured in square miles. C-Band won't have the coverage that lower frequencies have, but it's a lot more practical to deploy than mm wave. mm wave shines when you have a small, high-value area where you want to deploy 1,000MHz+ of capacity. Carriers might have 50MHz of capacity around 800MHz, 90MHz of capacity around 1.9GHz, 150MHz of capacity around 4GHz, and 1,000MHz of capacity around 30GHz. That really high frequency mm wave won't cover a large area, but there's a lot of it. If you're looking to cover a sports stadium, it makes sense. If you're looking to cover people's homes (even in major cities), C-Band is going to get you really good speeds with coverage that will be a lot more usable.

It's possible that you're getting mm wave, but those speeds are pretty normal for good C-Band coverage. The first test is pretty average and the second test is quite good, but nothing extraordinary.

reply
Everyone uses the example of stadiums, but the occupancy rate of stadiums makes the economics of the network and backhaul iffy. I would guess only the biggest NFL stadiums get it as a showcase. Maybe parts of Manhattan, too.

Chinese cities, especially at train stations and the surrounding area get really impressive flows of people every day. But even in China I would expect that while they might have a lot more 5G SA when in the US, that the radios are actually mid band and not millimeter wave for most coverage. You still get higher capacity and low latency, but most people probably don't notice the low latency, except maybe Chinese autonomous taxis faking it till they make it.

reply
My phone clearly shows me when I'm on 5G vs 5G mmWave.
reply
In Germany I notice a massive difference in 4G and 5G. If I see 4G on my phone and know I can put it away again if it's not some kind of an emergency because it's basically unusable. I am not sure what is going on here, probably the telcos that are limiting the bandwidth.
reply
There’s always a gradual refarming of the spectrum into the next G. Usually the most penetrating frequencies (ie lowest) are kept on the lower G to maximize legacy support.

For a while I had my phone stick to 3G, which doesn’t support emergency alerts, because my jurisdiction kept sending them out for joint custody disputes at 3AM 1000km away. It was fine But the 3G became unbearable and they tightened up the alert criteria.

reply
> There’s always a gradual refarming of the spectrum into the next G.

Not necessarily for 4G to 5G. 5G can run a 4G compatible control channel and timeslices can be 4G or 5G.

> Usually the most penetrating frequencies (ie lowest) are kept on the lower G to maximize legacy support.

Maybe, but at least in the US, 4G wad deployable on new lower frequency spectrum that had previously been used for TV. LTE 71, 600 Mhz is lower frequency but wouldn't have been usable for 3G because legacy phones didn't use those frequencies.

reply
The difference between 4G and (non-SA) 5G is fairly small compared to earlier generations. They use the same core network, and it’s actually quite possible to be connected to 4G and still see the 5G logo.

These tricks are less common in Germany though, as far as I’ve seen, so seeing 5G can serve as a weak proxy for “the carrier has at least touched this base station in the last few years”, which increases the chance they’ve upgraded its spectrum or backhaul a little bit.

Really depends on the concrete situation, though. Having a small 4G cell with 20 MHz of spectrum to yourself beats an overloaded large 5 MHz rural 5G site any day.

reply
I’d you have a 5G phone and plan but see 4G, that usually means you are at the very edge of coverage. Thats not the experience 4G was or still is if you are in a well covered area (which would have 5G available as well)

Interesting; in Australia I'm using exclusively 4G with no problems
reply
The thing that changed with 5G is that my iPhone 13 Pro‘s battery has been draining 30% faster. Enable the hotspot and it gets burning hot.
reply
My pessimistic take is it’s being optimized for the “numbers” users benchmark with. The 5G repeater towers that display on your phone as full-bars but the tower itself is constrained, to juicing the speedtests. Apple even changed how the RSSI translates to the bars. There are engineers doing great work, and the marketing teams muddle the waters (like ATT’s “5Ge”).
reply
ATT did a lot of this, android has a ‘feature’ they utilize to inflate the signal bar: https://android.googlesource.com/platform/frameworks/base/+/...
reply
I think it’s also because the best frequencies are already occupied by 2g/3g and 4g so it’s hard to provide good 5g coverage over large areas.
reply
3G has been shut down in several countries to free up frequencies. 2G was also shut down in several countries, it seems to be still up in most european countries with shut downs being scheduled in the next few years up to 2030.
reply
2G is hard to shut down, because it just works, and many of the core services and old phones rely on it. It will survive 5G, 6G, 7G an other Gs.
reply
2G is being shutdown (or already has) in many countries and those old phones and core services will need to be replaced.
reply
2G also needs a tiny amount of spectrum in contrast to the newer standards, as it was designed almost exclusively for voice calls, where a few Kbps is sufficient for good quality speech. (And 64kbps, which is only 8KB/s, is considered "toll quality".)
reply
4G is becoming the "baseline" and replacing 2G in many of those services, especially the "low energy" IoT implementations of LTE.
reply
Australia (2018), New Zealand (2018), US (2017), Iceland (2025), Switzerland have shut down 2G networks.

In Norway, Telia shut down 2G in 2025, but Telenor is holding out until the end of 2027.

In Sweden, Telia is holding until 2027, and all other telcos have already switched it off.

France is shutting down 2G this year.

So the 2G shutdown is a real thing.

reply
'best' is relative here; lower bands travel further, which is great for maximizing coverage footprint, but not great for high-density. Each node can only handle so much traffic, and you can pack them in more densely with short-range spectrum. mmWave really is the best frequency for very high density, high capacity networks, but the bottleneck is you have to deploy all the extra nodes to get the coverage.
reply
I’m not in the industry, so I can’t speak intelligently on this, but as a user, literally the only change I’ve actually noticed in my day-to-day is that when they removed 3G, I lost a shitload of connectivity. I live probably half a mile from the capital building in a greater metro region of over a million people and I still get shit connection at home on TMo. Maybe physics is the problem, but why waste time making things insanely fast in a lab setting? Work on making it fucking usable in the real world, like in a neighborhood with trees.

I do not give a shit if I can download at 500mbps while resting my phone on a wireless router. I need to be able to USE it.

reply
More likely, data usage has increased greatly in your area since 3G was still available and your carriers spectrum or backhaul hasn’t caught up. 4G/5G make things more efficient but ultimately can’t fight physics.
reply
Does this affect signal strength? I'm just annoyed I can't get more than two bars at home, or talk on the phone and take a shit at the same time.
reply
Ive never heard a single person say they don't see a difference between 4G and 5G, atleast in the USA.

Ive switched my entire home internet setup to 5G and haven't had an outtage in two years. Whereas it was once a week with fiber. I also can fallback with duel sims.

5G has legitimately changed my quality of (digital) life.

reply
That’s most likely because of the massive amounts of midband spectrum that became available for 5G use in the US and less so due to any inherent advantage of 5G.
