Huawei Claims 30Gbps Wireless 'Beyond LTE'

Posted by timothy on from the offer-void-in-australia dept.

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).'"

    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.

      Exactly. If I could stream a video stream that was my phone's full resolution along with audio that was decent, I couldn't care less if I got a faster stream. Give me an auto login to my home server and a Linux (or something else) desktop that is sized for my phone with remote desktop and I will have peaked my transfer speed needs. Honestly I don't even want most of my data on my phone, or on some third party's server. I want it stored in my home and streamed via vpn to my phone as I need it. If I lose my phone, I just change the password, grab a new phone and it is like nothing ever happened. This would also mean that I wouldn't care how fast of a processor the phone had, or how much storage it had. As long as it could decode the audio/video stream, I'm good to go.

      Moore's law? Not really. There are theoretical limits on maximum bandwidth that are far more restrictive than theoretical computation limits. For a given SNR, the maximum digital bandwidth of a communication channel is proportional to the frequency bandwidth. You can get closer to the Shannon-Hartley limit with better rf circuits coding, noise models, etc... but there's still a limit.

    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.

    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.
