It's a simulation [1]. The claim is that the technique is applicable to center frequencies below 6GHz and the 1Tbit/s used a bandwidth of 100MHz (for a spectral efficiency of 10^7 bit/s/Hz???). I'm guessing that whilst the technique might be applicable below 6Ghz, the 1TB/s rate isn't.<p>There are fundamental limits on the information capacity of an antenna using the EM spectrum [2], based on the surface area of the volume of space it occupies, in units of wavelength. (Related to the Holographic Principle?) I haven't done the calculation, to see if the claimed rate is within this limit, but a spectral efficiency of 10^7 bit/s/Hz is about 5 orders of magnitude beyond what others have reported (less than 100bit/s/Hz [3]). It will be interesting to see the details!<p>[1] <a href="http://www.ispreview.co.uk/index.php/2015/02/university-of-surrey-claims-1tbps-speed-over-future-5g-mobile-tech.html" rel="nofollow">http://www.ispreview.co.uk/index.php/2015/02/university-of-s...</a><p>"UPDATE 25th Feb 2015<p>We’ve been finding the 1Tbps claim a little difficult to
digest and so have been prodding Professor Rahim
Tafazolli for further details, specifically a greater
clarification of how the performance was achieved.<p>According to Tafazolli, the new class of Detector (a
completely new approach) was tested through computer
simulations (these simulated a real mobile/wireless
environment) and were found to achieve the 1Tbps rate
claimed. In our view that’s quite a bit different from
conducting a practical test.<p>Next year Tafazolli said that his team would work to
implement this in a proper hardware/software platform and
test it in a real environment in the 5GIC outdoor testbed.
Hopefully they will be able to announce the performance in
2017."<p>[2] <a href="http://arxiv.org/pdf/cs/0701055.pdf" rel="nofollow">http://arxiv.org/pdf/cs/0701055.pdf</a><p>[3] <a href="http://ieeexplore.ieee.org/xpl/articleDetails.jsp?reload=true&arnumber=6381034" rel="nofollow">http://ieeexplore.ieee.org/xpl/articleDetails.jsp?reload=tru...</a>
