In any case, it would mean transferring a BluRay in something like 30 seconds, assuming you had a faster drive.

What it would do is end the concept of "local storage". Online is faster.

Don't be so quick. Don't just consider single link transfers, remember that wireless is always shared bandwidth. If you have a terabit for everyone that means you can have hundreds of megabits for tens of thousands of folks in a small area all connected to one access point / cell tower.

  They are talking about terahertz bands that aren't suitable for distance communication, the ranges are practically measured in centimeters.

      Water vapor in these bands is a strong absorber limiting distance in earth's atmosphere to ~10 meters or less. Subtract a good deal for omnidirectional emissions and decent snr.

        That's very wavelength-specific, as this graph shows: http://upload.wikimedia.org/wikipedia/commons/thumb/d/db/Atmospheric_Microwave_Transmittance_at_Mauna_Kea_%28simulated%29.svg/350px-Atmospheric_Microwave_Transmittance_at_Mauna_Kea_%28simulated%29.svg.png http://upload.wikimedia.org/wikipedia/commons/thumb/d/db/Atm... Water and water vapor has the same effect on the visual part of the spectrum also, but this doesn't reduce people's enthusiasm for it as a potential communications medium. http://en.wikipedia.org/wiki/Terahertz_radiation http://en.wikipedia.org/wiki/Terahertz_radiation
