'At This Point, 5G is a Bad Joke' (computerworld.com) 199

An anonymous reader shared this skeptical opinion piece from Computerworld: Let's start with the name itself. There is no single "5G." There are, in fact, three different varieties, with very different kinds of performance... But, what most people want, what most people lust for is 1Gbps speeds with less than 10 milliseconds of latency... [T]o get that kind of speed you must have mmWave 5G — and it comes with a lot of caveats.

First, it has a range, at best, of 150 meters. If you're driving, that means, until 5G base stations are everywhere, you're going to be losing your high-speed signal a lot. Practically speaking, for the next few years, if you're on the move, you're not going to be seeing high-speed 5G. And, even if you are in range of a 5G base station, anything — and I mean anything — can block its high-frequency signal. Window glass, for instance, can stop it dead. So, you could have a 5G transceiver literally on your street corner and not be able to get a good signal. How bad is this? NTT DoCoMo, Japan's top mobile phone service provider, is working on a new kind of window glass, just so their mmWave 5G will work. I don't know about you, but I don't want to shell out a few grand to replace my windows just to get my phone to work.

Let's say, though, that you've got a 5G phone and you're sure you can get 5G service — what kind of performance can you really expect? According to Washington Post tech columnist Geoffrey A. Fowler, you can expect to see a "diddly squat" 5G performance... ["roughly the same as on 4G LTE," while some places "actually have been slower."] It wasn't just him, since he lives in that technology backwater known as the San Francisco bay area. He checked with several national firms tracking 5G performance. They found that all three major U.S. telecom networks' 5G isn't that much faster than 4G. Indeed, OpenSignal reports that U.S. 5G users saw an average speed of 33.4Mbps. Better than 4G, yes, but not "Wow! This is great!" speeds most people seem to be dreaming of. It's also, I might add, much worse than any other country using 5G, with the exception of the United Kingdom.

With a range of 150m, even if there are base stations "everywhere" you're not going to be moving from cell to cell that fast, with your data transactions moving transparently with you, without either a lot of latency, or a lot of lost network connections. Think about the network load for moving all those connections around and re-transmitting all the lost packets.

        Such scenario can be served a lot better with wifi. When there are massive number of people, the bottleneck is always the celltower / router, not the wireless technology part. Gigabit wifi is useful. Gigabit wifi that can serve thousands and thousands of people is useful. Gigabit wifi that connect to 10Gbps internet is useful. Gigabit 5G that is still data-capped is not.

          Err, no? When you are out of wireless bandwidth, you are out of wireless bandwidth and there isn't much you can do about it. Backhaul is comparably trivial.

        • So we make the next version of WIFI with automatic handover to the next base station, and build out free WIFI in all the high population density parts of the country. People can use 4G for everywhere else.
      • One of the benefits of this is the cellular providers can now provide ISP services. I worked at Verizon when they rolled out their 5g network, and I believe I saw that there were places they were offering ISP services over cellular networks.

        This is, once they get past the LOS limits of 5g mmw.

        Another example is where you need LAN speeds on a wireless network. There's a "city" where they test driverless cars. They need the LAN speeds there, but since the cars are mobile, it has to work on wireless.

      • I was surprised it went to great effort to point out how you might lose the super fast connection while driving. Well.. duh? If you're driving, you don't need the internet (and neither does your car). Your passengers can manage to survive without it too for brief instances; give the kids a book. If you're a commuter on mass transit, they'll give you wifi in some other way, but it's far better to just take it easy than try to work while commuting, sheesh.

        • Well.. duh? If you're driving, you don't need the internet (and neither does your car).

          Being able to work while commuting on a train (which is going to be faster than your car in most circumstances) is a norm in much of the world today.

          But it's often limited by spotty connectivity. Fixing this would be a great asset to work efficiency.

      Brick phones had no competition, there was no other way to make mobile phone calls so they were considerably better than nothing.

        5G doesn't have to be pretty spectacular. Phones get replaced on about a 3 year basis, so we are about 4 years away from near-total 5G handset domination.

        And yes, someone will chime in how much they love their 900MHz-only Nokia 2110. They are in luck, 2G is likely to stay alive in Europe significantly longer than 3G. It might beat 4G too.

        If 5G isn't noticeably worse than 4G, it will automatically win.

          The major point of 5G is to avoid Shannon's Law by doing massive MIMO. 4G doesn't support that. 5G is going to be feel like a miracle for festivals, stadiums and dense cities. It will pretty cool at 700MHz for rural areas too. Suburbs and smaller towns are fine with 4G.

    Like South Korea or Japan, and see 5G in all its glory.

    More seriously: The article shows a complete lack of technicall understanding from the author. Saying that 5G is three standards depending on the frequency is like saying that GSM was 5 standards because there are implementations in 450Mhz, 800Mhz, 900Mhz, 1800Mhz and 1900Mhz. No, in GSM (and indeed in all cellular standards) the signanling, framing, etc is done in the same way, no matter which frequency the operator happens to use. Besides, 5G is called 5G because is the ONLY 5G standard worldwide. In 4G we had 2 standards, in 3G he had 3, and 3 standards also in 2G.

    And this also neglects other benefits that 5G brings to the table, both for users (network slicing, improved latencies), operators (new markets, possibility to have more users attached to a single tower), or industry (autonomous freight trucks, edge computing).

    So no, 5G is no joke, is simply in its early stages, wait and see.

    No, that couldn't be more wrong. Very few people want or expect 1Gps. What we want is not even 1/10th that speed, but:

    1) Reliable- where we actually get real 10, 25, or 50Mbs continuously. Not 1Gps for 2ms every now and then, and 1Mbs the rest of the time.

    2) With range and coverage- where we actually STAY connected with reasonable speed, regardless of where we are.

    3) With reasonable power requirements- where we don't drain our battery in just a few hours.

    Super blazing speed that only works in one square block and only outside, without moving, and without anyone else on the network, is useless.

Radio amateurs have been doing this narrowband text stuff for years.
