Laser-based optical broadband could break all records with the use of fast Fourier transforms for demodulation. Research published in the journal Nature Photonics shows a possible data transfer rate of 26 Tbps, which the authors say could help to broadcast three-dimensional high-definition television signals and support the continued rollout of cloud computing. The key to the process, the Fourier transform, is a physical technique that separates all of the different frequencies out of a signal - in this case, out of a laser beam. It could lead to higher broadband transfer rates than have ever been demonstrated, as the researchers created line rates of both 26 and 10.8 Tbps with frequency-division multiplexing. By way of comparison, a typical three-minute mp3 compressed at a bit rate of 128 kbps occupies roughly 3 MB of disk space. That means approximately 1,135,957 radio-edit songs could be broadcast per second - enough to fill six and a half years of radio airtime.

Ok, sounds great! But I also have to wonder about any adverse health effects associated with this new technology. Not trying to be a downer, but before I made up my mind about it, I would want to know about these things as well, especially in the case of children, because you know they will want it installed in all the schools.
This is the kind of practical attitude I appreciate!

This is OVERKILL!!!
I would just be happy to have better service here in the US compared to other countries.
This is an article from '09 but i'm confident the numbers haven't changed much, except prices going up!
