Qualcomm (NASDAQ: QCOM) and Ericsson (NASDAQ: ERIC) have jointly announced that they have successfully tested the world’s first inter-company interoperability between Qualcomm’s Cat9 LTE (Category 9) MSM mobile chipsets and Ericsson’s LTE-A (LTE-Advanced) network infrastructure.

This test was done between the two companies in order to prove that interoperability is already possible on Cat9 hardware from both companies. Since, Qualcomm is both an infrastructure and client chipset company while Ericsson is only infrastructure since the company folded up the ST-Ericsson’s joint venture that produced competing products to Qualcomm’s Snapdragon processors.

The two companies were able to achieve the Cat9 450 Mbps speeds thanks to carrier aggregation (combining multiple frequencies/bands) that Qualcomm’s chipsets and Ericsson’s infrastructure are both capable of doing. Ericsson actually even tells us which hardware they accomplished this on, their RBS 6000 family of base stations for macro and small cell networks. Which means these are fairly small base stations and fairly short distance connections. Additionally, thanks to Ericsson’s specs of the RBS 6000, we know that Qualcomm and Ericsson used 60 MHz 3x carrier aggregation in order to deliver the Cat9 LTE speeds of 450 Mbps.

Qualcomm, unfortunately, doesn’t tell us which Snapdragon chipset this is that’s running the new 450 Mbps speeds, but they do say that it is a future chipset which could be something coming next year or something 2 or 3 years from now. We simply can’t know. But what we do know is that the carriers are very very unlikely to deliver anything anywhere near these speeds. The unfortunate reality, however, is that right now there are no carriers in the US even technically capable of delivering three 20 MHz different bands of  LTE based on their spectrum allocation. And even if they had the spectrum holdings to enable Cat9 LTE with carrier aggregation, they wouldn’t even have the backend to support it.

So, if 100 Mbps is something that we can expect in a year or two, why should we bother with the deployment of expensive fiber-optics cabling that (currently) achieves only 20/20 or 50/50 Mbps, if you’re lucky?

Good old copper wire proved its invaluable status – I am writing this while being connected to the Internet using 20Mbps stream coming down through 43-year old telephone installations (yeah, I do have those three-pin large connectors), but it seems that copper-based networking standards aren’t dead yet.

Networking wizards at Swedish telecommunications giant Ericsson came up with improvements that are nothing else but breathtaking. Researches at the company managed to introduce couple of new technologies to VDSL2+ protocol. Key feature is now “crosstalk cancellation” and “line bonding”… Crosstalk Cancellation works by looking for any presence of noise on the line and increasing the signal strength and is the main culprit why your home will have Internet connection in excess of 500 Mbps (62,5 MB/s). If your house is withing 500m from the modem pool, that is.

And now wait to hear “analysts” and “experts” who are saying that Internet will collapse. Get a decent internet connection before crying loud, guys’n’gals.

This specification covers all GPGPU-capable hardware, regardless of that hardware being in servers, workstations, desktops, notebooks or handhelds – if your GPU is able to compute, the manufacturer only needs to adopt OpenCL support in the driver and that’s that.

That should not be an issue, with AMD/ATI and Nvidia strongly standing behind the standard. Computing engineers on both sides bickered about Brooke+, CAL or CUDA in the past, but both makers are firmly behind OpenCL as the way for the future.

So far, companies that developed and ratified this initial spec include 3Dlabs, Activision Blizzard, AMD, Apple, ARM, BARCO, Broadcom, Codeplay, Electronic Arts, Ericsson, Freescale, HI, IBM, Intel Corporation, Imagination Technologies, Kestrel Institute, Motorola, Movidia, Nokia, NVIDIA, QNX, RapidMind, Samsung, Seaweed, TAKUMI, Texas Instruments and Umea University.

You can learn more at the official page of OpenCL API, but I wasn’t able to check the site as it was hammered down with numerous requests (this story was written at 10:05AM CET).
