The device sounds like it's going to be valuable, should it ever reach commercial viability. Having a movie on my smartphone, however, is just about the last thing in the world I would want, whether or not it arrives in seconds or years.

Or may take a few minutes for the refresh to work if servers are busy. Interesting article on this use for graphene. The statement "Today, optical modulators are used to speed communications by using electrical signals to switch a laser on and off" was confusing at first until reading further indicated that the author was referring to switching the optical path on and off, not the electrical current to the laser itself. As for the bit rate, this sounds like a first cut. 1Gb/s now, 500Gb/s later after more research and improvement.

When making posts it takes a bit of time for the paragraph breaks to get processed. Use the 'Enter' key in the normal fashion. Then after clicking on the 'Submit Comment' button, refresh the page, a few times if necessary. It may take several seconds for your text to show up again, but this time it will have the paragraph breaks. Or go back to the home page, keep refreshing until your post pops up, then click on your post. This has the same effect as the refresh.

I, for one, do not want a smarphone that is tethered with a fiber optic cable. [p]Why do these releases always have to dumb down to the point of being just plain ridiculous in their grasp for relevance? It would have sufficed to say "DSL" instead of "smartphone". [/p] [p]One more thing: 1GHz (500MB/s) is a joke - we were already there in 1989....we're at 100Gb/s SHIPPING commercially now kids. "Can", "might", and "should" are for comic books.

I have been following the various articles on graphene for the past year. It is truly an amazing material holding great promise in the electronics field. A 500GHz data path per user over a wireless cell phone network? Now that would be something to see - no pun intended.
