LTE networks of the future could peak at 30Gbps
posted by Nick T. / Mar 27, 2012, 4:04 AM
Today's commercial LTE networks are pretty fast, but they are only going to get faster in the future. Ridiculously fast, judging by what the guys at Huawei have accomplished. The Chinese company announced that it has developed what it calls Beyond LTE technology, which should be capable of reaching transfer rates of up to 30Gbps. That is 30 gigabits per second, with 1 gigabit equal to a thousand megabits of data.
"key breakthroughs in antenna structure, radio frequency architecture, IF (intermediate frequency) algorithms, and multi-user MIMO (multi-input multi-output)". Reaching these hypothetical speeds would require a lot more frequency spectrum than what contemporary LTE networks are allowed to use. We are not exactly sure how much bandwidth would be needed, but since the LTE-Advanced standard can run on no more than 100MHz of non-contiguous spectrum for a maximum speed of 3.3Gbps, Huawei's Beyond LTE would presumably require considerably more bandwidth than that. In comparison, today's LTE standard utilizes only 20MHz of contiguous spectrum and peaks at 300Mbps.Of course, there is a catch, for Huawei's technology takes advantage of not only
The Beyound LTE technology by Huawei might not become commercially available anytime soon, if it ever gets adopted at all. Nevertheless, it is pretty awesome knowing that companies are constantly working towards shaping the future of wireless networks.

You know nothing about Huawei. They are not just the manufacturer of those phones you've been seeing here in PA. They also develop the technologies on cellular towers and radios.

You couldn't blink fast enough to see your phone reach its data limit... if the battery was big enough to last that long. And then you'd have to wait an hour for it to cool down enough to put back in your pocket. The future is going to be so sweet.

This is really good news but I just don't see how speeds that high are going to be necessary. Page loads for even the heaviest data consuming sites can be achieved instantaneously with speeds much slower than a Gigabit down/up. No multiplayer game, no VoIP app, no video call or HD video stream will ever need that much speed in transfers for it to be able to run flawlessly. I look forward to faster speeds but should this someday come to US networks, I could only imagine the price to pay for such a premium service. I just hope its reasonable. I'll take 100 mb down and be happy forever. That is unless some breakthrough product comes out that needs such a high demand for data transfers (which I still don't see happening).

first of all hard disk write rate much much lower than this :D

Just for reference, 30 Gigabits per second = 3.7 Gigabytes per second. This is also equal to 30,000 Mbps. But this has nothing to do with a data limit (such as 2GB or 4GB per month), but is purely the speed of a download. The faster the download speed, the less time it takes.

ha, and you guys scream about data limits now.. lolz that kind of stuff is unlikely to be for phones.. more like cars and other things that might require megafast download speeds.

The only problem with these technology is it is not pratical to use, because the faster the speed the more energy is need. So I dont see the good use at this speed, with that speed our phone might catch fire or drain out battery in an hour unless we need comeup with battery break throug like increase the battery 20 fold then .........

Maybe this is what they’re referring to. NOTE they refer to SITE PEAK SPEEDS, NOT USER SPEEDS. It’s more like a backhaul solution for LTE and LTE-A towers. By 30 Gbits/sec, they might simply mean the tower can support 100 LTE users at 300 Mbits each or 10 LTE-A users at 3 Gbits each. http://www.huawei.com/ilink/en
” Huawei announced the demonstration of Beyond LTE technology at the 2012 Mobile World Congress. This new technology will significantly increase site peak rate to 30Gbps, over 20 times faster than existing commercial LTE network.”
Also this is the actual announcement they made at the 2012 MWC, a new 10 Gbit/sec ETHERNET router for Cell Sites. It’s ETHERNET, not wireless – that’s why there are no references to spectrum requirements
As the world’s first 10GE CSR, ATN 950B covers bandwidth increase from 1GE to 10GE during LTE phases, even beyond LTE
