Huawei Claims 30Gbps Wireless 'Beyond LTE'
shreshtha writes "Huawei says it has 'recently introduced ... Beyond LTE technology, which significantly increases peak rates to 30Gbps — over 20 times faster than existing commercial LTE networks.' It claims to have achieved this with 'key breakthroughs in antenna structure, radio frequency architecture, IF (intermediate frequency) algorithms, and multi-user MIMO (multi-input multi-output).'"
Of course it's a "peak" rate. If you sustain that rate for two seconds, you'll have already more than blown through your entire cap of 5 GB (40 Gbit) per month.
So which company had its fancy new antenna tech lifted for this. China's R&D = Reconnaissance and Deception.
Seriously, I think we are entering into a period where the bandwidth is way more important than the processor. I am sure that Moore's law can be manipulated into something that will predict how quickly things will advance.
It wasn't that long ago that mobile bandwidth was pretty much useless, now we have speeds that have surpassed early home wireless networking.
I live in a rural area, only have 2G, I'm waiting for 3G, but I'm not sure it will ever quite get there, my provider will most likely just jump it and go to whatever the next level is, making my phone obsolete in the process. Of course with a bit of luck, the standard will be backwards compatible, but at some point they will have to just abandon some technology and look forwards.
and AT&T will be able to charge overages in less than 1 second. I wonder if their servers will be able to throttle you in at 0.7 seconds into a large download.
Never say never. Ah!! I did it again!
I find it refreshing to see them creating new technology instead of just implementing standards.
Plus it just confirms my comments yesterday about even engineering and design talent moving overseas; that no job is "safe" any more from the risk of being offshored. Given Huawei's market share in the telco industry, this particular bit of engineering should make anyone still working for the formerly big names in telecommunications some serious pause when they think about their job security.
It isn't that long ago that people thought a job with Northern Telecom would last a life time, and we know how that turned out for those who believed in that dream.
I do not fail; I succeed at finding out what does not work.

Huawei is a Chinese company just recently been banned from quoting on Australian government contracts amid suspicion of putting backdoors into its kit for the Chinese government:

So we have a lot of announcements recently about how amazing and indispensable Huawei kit is. But like this one, they can't point to a single breakthrough, its all kind of vague claims that can't even pinpoint what breakthrough they made. It's all very much like a Chinese pride thing.
Soooo unimaginative. Ever considered that phones aren't the only devices using mobile internet? Realised that in areas only serviced by ADSL and cable, that LTE gives you by far the highest upload speed?
Not only can they not shake off the reputation of being too close to the Chinese government, their hardware is usually lower-tier.

yeah, that's what I came to post: it seems to be a violation of Shannon's Law. But, then again, the Chinese are known for violating all kinds of laws.

Which came from espionage of a First World company, as Chinese "companies" are wont to do.

The more reason to halt the move and reverse it, even if it takes force. With enough force, even the most "irreversible" things in economics can be made to reverse course back to the First World. Job security is something worth preserving in the First World, even if it comes at political costs.

That can be restored with law. Given how badly Huawei implements things, their technology is only good for a political prop when countries rightfully reject it(Australia, US).

Standards are wonderful things, oddly enough almost nobody actually rolls into active service products meeting all these fancy numbers.
In Down Under Land (Oz tray Lee Uh) Telstra rolled out an LTE network. Sure In Theory LTE can deliver "Up To" 300Mbps. Despite Telstra being very much a PREMIUM service provider their shiny-new tech delivers speeds which are not even in the same city, let alone the same ballpark. (to use an Americanism)
Now don't get me wrong folks, LTE is MUCH better than HSPA+, but absolutely nobody on the Telstra LTE network is getting even HALF of the "maximum theoretical throughput of an LTE network".
So if "LTE can do 300Mbps" means end-users are getting maybe 35Mbps, then the JOYous claims of "up to 3.5Gbps" might maybe one day deliver 100-200Mbps of real-world actual throughput.
And while I'd hate to be the person who claimed that "640K is enough for anybody", I do honestly believe it will be quite some time yet before a mobile-handset (phone, iPad, etc) would need more than "one hundred megabits per second" (or thereabouts).
People driving WiFi gateways or using cellular communications from a "fixed location" scenario would. And that will lead to a two-tiered service, you can pay X for "mobile usage" which is FAST (by todays standards) but not pushing the limits of the technology, or you can pay XXXtra for Ludicrous Speed and the caveat being "not for mobile handsets".
This would keep the vast unwashed masses from snowing the network, and the premium/business-grade/etc users will still have plenty of capacity.

Repeat after me: NOBODY is going to build a cellular network which will *guarantee* actual real-world throughput of 150Mbps for every user in their footprint in anything even approximating the near future. Possibly not even in my lifetime.
The cost in towers, spectrum, and backhaul is economically prohibitive.
Sure they'll sell you "up to" mumble-something, but that's just an opportunity to let the network get congested at either the wireless or backhaul level and not care.
NO Wireless technology scales to compete with fibre-to-the-user when you consider *uncontended capacity*.
And THAT is why fibre-rollout projects are worth it in the long-term. (Heh, if nothing else, said fibre will be needed to support all them shiny-new cellular towers each of which covers less than 7 homes)

They don't need caps at the 2 or 4 mark even now. It's just the abusive practices of a tight-fisted duopoly. Consider that the towers go virtually unused between 12 AM and 8 AM. Why not give everyone unlimited data during off-peak hours, the same way they did with voice (unlimited nights and weekends)? Now you see this is about earning more money through punitive overages than about providing service.
While some might dream of a return to "America First" and "Made In Canada" policies and tarrifs, I can't imagine us ever returning to such systems.
First and foremost, the consumer won't stand for it. The consumer now expects computers at under $1000 instead of the $2000 plus it used to cost to manufacture them onshore.
A recent article I read pegged the "Made in America" price of an iPad at roughly $1400 -- more than double the market price. At such prices, people simply would stop buying them, because it's pretty damned hard to justify toys over $1000 in most people's minds.
I don't think it's a good situation for the "First World" at all, but I can't see any of the companies involved in offshoring being willing to return to North American manufacturing and assembly when it would make their products completely uncompetitive in the rest of the world markets. Quite frankly, companies like Apple make far more from their foreign sales than they do from North American sales. As a result, if you returned to a nationalistic policy on manufacturing, they'd simply pull up the remainder of their North American roots, officially become a foreign company, and keep on with business as usual. With the US one jewel less in the globalization crown.
And the same goes for all the other big multinationals. The only thing keeping their head offices in the US or Canada is tradition. Globalization has become an unstoppable behemoth; no one with real influence over the government through lobbyists would tolerate stepping back from globalization.
Let's face it -- the corporations sold out the people by lobbying the government for years or decades, and the people were too engrossed by their television sets and Big Macs to notice until it was too late.

640KB is not enough for everyone, but it is enough for some people. It's just about enough to edit long text documents and simple images. 6.4MB is enough for more, it's enough for long rich text documents and occasional more complex images. 64MB is enough for more, it's enough for editing large photos. 640MB is enough for nondestructively editing complex photos and enough for simple video editing. 6.4GB is enough for realtime nondestructive video editing. 64GB is enough for... pretty much anything we use computers for today.
There will always be new applications that require more RAM, but often they are fairly niche products. The same is true of bandwidth. Waiting to load web pages irritates everyone. Waiting to load images irritates most people. Not being able to stream video irritates fewer people. Not being able to stream HD video irritates even fewer. Not being able to interactively stream 3D volume datasets probably only irritates a few dozen...

"I don't think it's a good situation for the "First World" at all"
Sure it is. Think of offshoring as your tax for helping the third world to industrialize faster. Conditions and labour rates rise in the beneficiary countries until they start their own post-industrial economies. Japan, Hong Kong, Korea, Taiwan, India and Mexico are past the initial industrialization stages. China is getting there. Soon we'll (all) be outsourcing to Africa and getting them up to speed. Just like England did with America.
