Tin foil hats obligatory
That is all.
A group of university researchers in Japan say they have achieved wireless data connections of up to 100Gbps with a new transmitter operating at the submillimetre terahertz frequency range. The team operating out of Hiroshima University, Panasonic Corporation, and the National Institute of Information and Communications …
That is all.
Most people shudder at installing structured cabling in their homes, but that seems to be the requirement for these future wifi technologies. Not too hard in a lot of houses to install multiple APs from the ceiling space.
If you have to have structured cabling in the wired format to begin with, why not simply bring it to a port on the wall?
I was excited by the headline but the caveats pretty much annihilate it.
Yes but the attenuation is going to be rubbish in that range
..or wonderful - depends how urban one's environs happen to be.
Source article - a range of tens of metres...... that's a LOT of access points.........
That'll drop to tens of centimetres the moment there's any fog or rain... even humidity will affect it at those frequencies!
"Err, but only in the same room..."
As anyone on the end of a xDSL line knows it's the Attenuation, stupid! 100Gbps Bluetooth maybe?
If the range is so limited I don't see how they can, on any level, compare it with Fibre optics since the key features of fibre are high bandwidth AND low attenuation/metre.
Maybe it can be combined with nano-material surface wave-guides as a new form of antenna - Dulex* WaveGuide Vinyl Silk?
*not Durex, although that 'raises' alternative antenna ideas :)
"... at 300GHz, would break the terahertz frequency barrier."
How does a 300GHz transmitter break the Terahertz frequency barrier? Are they talking about the upper sideband limit when modulated at 100Gb/s? If so it seems like a terminology cheat.
