World's First 5G Field Trial Delivers Speeds of 3.6Gbps Using Sub-6GHz

Posted by timothy on from the saturation-is-the-goal dept.

Mark.JUK writes: Global Chinese ICT firm Huawei and Japanese mobile giant NTT DOCOMO today claim to have conducted the world's first large-scale field trial of future 5th generation (5G) mobile broadband technology, which was able to deliver a peak speed of 3.6Gbps (Gigabits per second). Previous trials have used significantly higher frequency bands (e.g. 20-80GHz), which struggle with coverage and penetration through physical objects. By comparison Huawei's network operates in the sub-6GHz frequency band and made use of several new technologies, such as Multi-User MIMO (concurrent connectivity of 24 user devices in the macro-cell environment), Sparse Code Multiple Access (SCMA) and Filtered OFDM (F-OFDM). Assuming all goes well then Huawei hopes to begin a proper pilot in 2018, with interoperability testing being completed during 2019 and then a commercial launch to follow in 2020. But of course they're not the only team trying to develop a 5G solution.

      No no no. We French fucks at SI dictate that G is for giga.

      You can never use G for anything other than giga. g is for gram, but we don't use g for the base unit of mass, we arbitrarily use kg as the base unit for mass even though k is the prefix for 1000. However, 1000 kg isn't kkg, as our own rules dictate, but Mg, which is megagram. Note the capital M, we use big letters when we're scaling things up in magnitude and small letters when scaling them down.

      Except for k, as noted previously, because K is for Kelvin. And also except for h and da. We'll gloss over h and da, as well as d and c, because we got drunk and included them even though every other prefix is based on powers of 1000. Yeah, we woke up next to da one morning and it wasn't pretty, I can't believe we included a prefix with two fucking letters when every other prefix is a single letter.

      Back to M. M is MEGA and means 10^6, while m is milli and means 10^-3 (but M is also mass and m is also meter). Now, I know you thought that M being 10^6 would mean m was 10^-6, but it's not. (It's just not, okay?) For 10^-6 we use a u, but not a regular u that you can write or type easily, a squiggly ass Greek fuck of a u. This fucking guy: . Sure, we could have used u since it's not in use in any other base unit, dimension, or prefix, but fuck you, we're French.

      But don't worry, is the only one like that, unless you count the dimension symbol for temperature, or the 2nd-tier named units where is for Ohm (we haven't used O but we were worried it might look like a 0 even though we dictate that you must put a space between quantities and units) while C is degree Celsius (because C is for coulomb).

      Now, you might be thinking that we should have used c for coulomb and C for degree Celsius. I'm sure that capitalization led you to believe degree Celsius is named after someone whereas coulomb is not. In fact they are both named after people, but degree Celsius is the only named unit in the first or second tier of base units that has multiple words. We actually dictate that named units start with lower case letters except when any regular ass word would have its first letter capitalized, such as at the start of a sentence. However, since degree Celsius is two fucking words, we decided that Mr. Celsius would always be capitalized, just because. This left us with no choice but to use C for coulomb and C for degree Celsius. Of course when pluralizing degree Celsius we go to degrees Celsius, not degree Celsiuses, even though "degree Celsius" as a whole is the fucking term.

      Where was I? Ah, yes, the . Don't worry, after we go to n, which is for nano, or 10^-9. This is the counterpart to G (for giga) which, as I explained previously, is only for giga and not the universal gravitational constant, so please get it right. It's all so simple and consistent!

    So, 3.6 Gb/s is cool and all; but I did a quick check and Verizon is calling 18GB/month the 'XXL' plan, so this appears to be largely an exercise in accruing overage fees even faster.

    It seems like what will matter much more(unless somebody is planning to use the same tech for highly directional point-to-point wireless links, in which case raw speed is pretty useful); is how well these '5G' arrangements handle congestion; and how efficiently the amazing-fancy-theoretical-peak-throughput can be divided across a large number of users. Unless you are made of money, the problem with wireless data isn't so much how slow it is; but how costly it is(in part because of scarcity, which more efficient RF technology might actually alleviate, the 'because we can' part is a separate issue); and how it has a habit of just collapsing in a screaming heap under heavy load.

    If the impressive peak bandwidth numbers indicate a larger pool of usable transmission capacity extracted from a given chunk of spectrum, fantastic, that is progress. If they simply represent what you could do if a single client used every doesn't-play-well-with-others trick in the book to get better speeds, that's utterly useless.

      I'm not worried. New equipment will be stamped out and installed into existing towers. Nothing new here as that's how it always happens. If the laws of physics become an impediment, so be it; the limitation will set expectation and thus the industry will adapt. Meaning, don't expect 8k or 16k video formats streaming over cellular service anytime soon.

      The new hotness will be voice over WiFi anyways. Xfinity (Comcast) already has a large WiFi router install base already, each one broadcast the same public SSID. The idea is that you can roam between areas with Xfinity and route all traffic through their network and not my cellular provider. In fact, I do that already with my familiar places I often visit. No need for a 6GB monthly plan. And unless you're a road-warrior, there's no need for you to have one either.

      My cable ISP has caps too. I really don't mind caps, provided they aren't too low. They have to find some way to give people high speeds and somehow restrict people from saturating the connection 24 hours a day.

      For me, a faster connection isn't just about more throughput, but more about having individual pages load faster, not waiting for videos to buffer, and being able to play a game on release day, rather than have to wait until the next day for the game to finish downloading.

      For a mobile connection, I want the data I'm looking up to come in fast. But I know I'm not going to be downloading 4K movies on the bus. It would be nice, but I realize there are limits to what we can get.

      I don't really think we need a 3.6 Gb/s connection on mobile, as most of the connections will be closed before the TCP window reaches that speed, but I guess it really can't hurt to have the capacity available when you need it. I guess it just realistically means they'll be able to have more customers downloading at reasonable speeds.

    • Very high throughput even when the user is moving very fast (e.g.high speed train travel upto 300 kmph).
    • Very low latency connections (1-10 ms)
    • Support for massive city-wide or region-wide deployments of Internet of Things over low power cellular connections
    • Very high spectral efficiency leading to reliable high throughput connections in densely populated neighboords
