World's First 5G Field Trial Delivers Speeds of 3.6Gbps Using Sub-6GHz
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.
Just like 4G isn't 4G and 3G isn't 3G. Other than corporations continuing to rip people off here, what is new?
Time is what keeps everything from happening all at once.
Japan is planning to have a 5G network operating in time for the 2020 Olympics. We are going to see a lot of new tech pushed for 2020 because of that opportunity to show it to the world. Faster trains, 8k TV broadcasts, lots of new EV and hydrogen cars...

"Huawei's network operates in the sub-6GHz frequency band"
Is that the unlicensed 5Ghz band?

Who else bets they're going to include a thousand tracking "features" down in the network's specification to prevent any chance of anonymous browsing?
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.
almost exactly save the 2way radio feature, which is also free?
My previous phone was a Huawei Valiant. The battery life was terrible, and the battery stopped working and needed to be replaced pretty early. It was rootable, though. When I first got it, the screen started glitching, but it got better later.
I read somewhere that the largest initial benefit with the introduction of 4g was that 3g networks improved as the real heavy data users upgraded. I wonder if the same thing will happen to 4g when 5g is introduced. It's nice to be behind the curve but benefit anyway!
I have the Verizon 1GB/month plan. With these speeds, I should be able to hit the cap within 1/3 of a second. Not sure that "5G" really benefits anyone.

That's awesome. You can reach your data cap on Verizon in under 5 seconds.
Don't they basically just rip off Cisco hardware and software?

Huawei? Those shape-shifting squid things
As opposed to shape-shifting kid things?
And don't try telling me that LTE is 4G.

Sub 6 Ghz .... is that better known as 5 Ghz?
because now they can charge me for going over my data cap in minutes instead of hours.
These are some of the important objectives. Speed is just one of the criteria for qualification. In that sense, the test described in the article seems to be more like 4.1 G in the same way plain LTE (i.e. not LTE Advanced) is 3.5G.
