5G Skeptic (tbray.org) 97

Tim Bray, writing in a blog post: When I was working at AWS, around 2017 we started getting excited pitches from companies who wanted to be part of the 5G build-out, saying that obviously there'd be lots of opportunities for public-cloud providers. But I never walked away convinced. Either I didn't believe the supposed customers really needed what 5G offered, or I didn't believe the opportunity was anywhere near big enough to justify the trillion-dollar build-out investment. Six years later, I still don't. This is a report on a little online survey I ran, looking for actual real-world 5G impact to see if I was wrong.

The worse that can be said about the blog post is that it's anecdotal, so low on the stuff that hardcore geeks want (benchmarks, benchmarks, benchmarks). And no, the guy doesn't say that 5G causes cancer or covid.

      I just wish someone could explain 5G in a way that makes sense because I fundamentally don't get it.

      From what I can piece together current 5G is the same modulation as LTE. The marketing promises of 5G in terms of density and speed are a function of using higher frequencies which trade performance for distance. Unless you are in a high density area with lots of micro towers everywhere you will be stuck with traditional towers /w 5G on low bands and this will be different from 4G how? More MIMO stacking

      • While I am also lacking technical details, my anecdotal experience is that it is allowing carriers to add more towers where they want them, in ways that were not viable with "4G". My condo now has a cell site for T-Mobile, along with another one just down the road.

        Also anecdotally, I find it leads me to use cell service more than free WiFi when out and about as functionally it provides a better experience.

        Otherwise pretty much a nothing-burger.

      • Generally speaking 5G is very high frequency LTE as far as I can tell. The higher the frequency the greater the data payload. It is short range and thus could be perfect for the last mile or more to the point 1/4 mile. My neighborhood has a couple of players that came and shit units all over the place on new poles.

        How is it possible to use the same frequencies and the same modulations and get substantially different results?

        5G and 4G don't use the same spectrum. 5G uses substantially higher frequencies.

        just replacing existing 4G towers with 5G towers would as far as I understand it result in no substantial difference.

        If we replaced all the 4G towers with 5G towers, the difference would must assuredly be substantial -- we'd have almost no coverage! 4G towers have about a 10 mile range which is substantially more than the ~1000ft you get from a 5G tower. 5G needs a lot more infrastructure.

        • 5G and 4G don't use the same spectrum. 5G uses substantially higher frequencies.

          You seem to think that only 27ghz deployment is 5g, the 3500mhz 5G is also 5g but with significant differences in properties.

          It's that there are real physical limits to the amount of information you can move over a chunk of spectrum at once. More bandwidth means you can handle more people. If you don't mind a little math, I have an example that's pretty easy to follow.

          If you have directional signals and reuse the same spectrum spatially, that is one way to increase throughput. Which is the approach the lower frequency 5G uses at great computational cost.

        • by bn-7bc ( 909819 )
          not necessarily, at least here in Norway they recently (wall about years ago) shot down 3G and repurposed the frequencies for 4G/5G, so while not being able to provide the Gbps services being promised by mmWave 5G it will still be 5G (same air interface, modulation etc) and probably the same coverage/site 3G on the same frequencies , just with the other improvements of 5G (more rf efficiency, converged infrastructure etc)

          As far as I understand it this is not true. For example n71 is used for 5G and is only in the 600mhz range.

        So what is the deal with 5G in concrete terms? How is it possible to use the same frequencies and the same modulations and get substantially different results?

        The answer there is dynamic beam forming, and it's what has led to a fair chunk of the complexity of 5g hardware. This will take some background.

        Existing 4g telco panel antennas are effcetively internally arrays of dipoles. usually two or four arrays for the lowest band (700-900) and four or eight arrays for common 4g bands (1800-2600). Many dipoles are stacked vertically for each array, but usually only a single dipole wide.

        The reason for them being in pairs is due to polarity, they have +-45 degree slants. Anyway, the way these function is the signal at the input is split on an internal phasing harness that at 0 e-tilt ensures that the signal reaches each dipole at the same time. Ensuring constructive interference along the boresight and getting you your directional beam. Most phase harnesses have provision for slightly altering the timing so the beam is electrically tilted downwards, but changes once set up are uncommon.

        Enter 3500mhz 5g. While not significantly higher in frequency it's higher enough that the dipoles are smaller and you can fit more of them in the same area. Instead of being in fixed arrays with a common signal being split among them each has an individual connection to the remote radio unit.. which for not having a bunch of connectors is now usually built into the antenna although there are some exceptions.

        5g sends out a reference signal, which through some nice direction finding finds out where the device to be spoken to is both in azimuth and verticle angle.

        Instead of a fixed beam, it dynamically changes the phasing (this is computationally very intensive) of some of the array to direct a specific beam to the user. It can at the same time be doing the same thing for another user on the same frequency if the angle is sufficiently different.

        When you aren't blasting it everywhere but only fixed targets spectrum reuse can be largely increased. Even in a single tower replacing 4g you get these benefits but the more it's reused and the more targeted the better the benefit.

        I have made some simplifications and could write a bunch more on this, but this is probably enough to get the idea.

        • The answer there is dynamic beam forming, and it's what has led to a fair chunk of the complexity of 5g hardware. This will take some background.

          This isn't exclusive to 5G. LTE has beamforming / MIMO (Up to 8x8 on LTE-A) too.

          Is it just a function of higher frequencies = smaller waves = higher spatial resolution? Is it just tweaking parameters like stacking more antennas? Or asked another way what is LTE missing that is exclusive to 5G?

        It will cost more to add more antennas because it’s coverage limited to line of sight only, but this is overcome by the massive potential profits and revenue streams.

        High-band 5G is pretty much limited to line-of-sight, but 5G in general can operate in a wide range of frequency bands, including the 850 MHz band, which penetrates buildings just fine. But because higher speeds necessitate wider bands, telcos won't be able to support nearly as many users at higher speeds in those lower bands.

There really isn’t much of an upside at all to customers except perhaps if they suffer reduced performance in very high usage areas.

            T-Mobile is deploying 5G as far down as the 600 MHz band. And unlike 3G, LTE and 5G can coexist in each frequency band. So if you're used to a 700 MHz band now, you'll probably have access to 5G service in that band as well, either through dynamic spectrum sharing with LTE or because your carrier dropped 3G service in that band and deployed LTE and 5G in it instead. The main difference is that your phone will be using a more efficient coding scheme that gives you somewhat better throughput than it did wh

            • This is exactly what I said initially. Very little discernable difference to consumers, they pay the same or more and keep the same data caps. The main benefit is carriers sell the excess bandwidth to anyone and everyone.
      • It will cost more to add more antennas because it’s coverage limited to line of sight only

        False. Nothing about 5G or many of the benefits is brings (including some of the ones you mentioned) requires it to use high frequencies, that is completely optional and used to increase speeds in some cases. The point of the standard goes far beyond bandwidth, the point of speed goes far beyond how much you can download in a given time.

        • Yes, but this is not what is marketed at all. There are almost no direct benefits to consumers, they get less %bandwith from the system for the same cost. All the additional bandwidth is just going to be sold to make more profit.

They are quite used to sending a guy out in a truck to check substation breaker status. What they do need is something that will work through the rain, trees and other crap for miles. Because the telcos are never going to build out a high density network to serve low density customers. They didn't when they switched from 2G and 3

  • I live well within (only 10 miles or so from the center of) one of the 25 largest metro areas in the nation and neither LTE nor 3G are strong enough at my home to utilize. There is never more than a bar and calls are frequently dropped. If it weren't for my phone's WiFi connection through my cable provider, I'd have to have a landline. And it isn't just my home. I lose calls while driving along major boulevards throughout the area. I see no excuses. The land throughout the region is flat, and there are few

    • I live less than 1 mile from a major freeway in California, in a fairly dense neighborhood. I get no signal in my kitchen and 1 bar in the rest of my house. Without a micro/femto cell or wifi calling cell phones are useless in my house.

      Correct me if I'm wrong, but 5G is not intended to replace 4G LTE in all locations. It's intended for high density use, like in a few metropolitan areas. The attenuation of the 5G bands is so bad that it is of practically no use unless there is a clear line of sight to the base station.

      I get two bars of coverage on 4G and I can step out my front door and see the base station antennas about half a mile away. Through the trees. 5G? Not going to happen.

      • Correct. The first 4G LTE sunsets should be post-2030. What 5G does do, though, is siphon off investment in expanding basic coverage in favor of rolling 5G radios out into high density areas.

        As to both of our coverage situations, the antennas used by the stations are highly directional. I also have antennas in sight that operate on the frequency of my phone. Regrettably, the antennas on the tower in sight are pointed lengthwise along a major roadway. I am well out of that tower's cones.

  • Skeptical? So who still believes that the roll-out of 5G & the COVID-19 pandemic are simply a coincidence?
  • I pay my mobile provider more for extra data and do all my work via a hotspot on my aging Pixel 4.

    Interestingly, the Marina also provides a WiFi signal which is pathetically slow and unreliable compared to the 4G data; the notion that WiFi is the gold standard for wireless Internet is pretty well over.

    Why would you say such a stupid thing? He's literally using WiFi and it's faster than the WiFi they provide, so WiFi must be crap?

      sp Wifi at a Marina is crap hmm, is this Wifi you pay for (as in x time/data costs y) or is it "free wifi" that the marina gives it costumers as a curtesy? If the former you should really complain to them as a service you payed for really died not provide the expected service, remeber to talk to a manager, as the person manning the costumer service desk/ "chekin/checkout" has enough crap already, if the latter tough you got it for free shut up.
      • I was talking about this incredibly meaningless statement that sounds exactly like someone who doesn't know anything would say:

        the notion that WiFi is the gold standard for wireless Internet is pretty well over.

        This is where I stopped reading the article. That's such a stupid statement, you know that there is no useful information this person can possibly have for you.

  • Is they shut down 3g effectively reducing the range of devices. 5g implementations do not have the same range. In addition to that, many M2M and IOT devices have to be upgraded or abandoned. All this so the cell industry can give you another reason to buy a device or upgrade your plan

    • by bn-7bc ( 909819 )
      does 5G have worse range/coverage than 3G at the same frequency and transmit power? physics are still physics so those limitations donæt change, you have to compare like with like .

Money will say more in one moment than the most eloquent lover can in years.
