According to an article from The Register, a team from Stanford University has patented technology that could halve the bandwidth that a mobile provider needs.
Operating under the name Kumu Networks, they are showcasing tech which they claim would exactly double throughput. Radio equipment (such as mobile phones) would be able to send and receive on the same frequency through a process similar to noise-cancelling headphones; by knowing what a base station is transmitting it can cancel out the information from the very faint signal it receives.

I'm not a robot like you. I don't like having disks crammed into me... unless they're Oreos, and then only in the mouth.

really? I thought upper sideband was the upper half of the modulated carrier waveform and lower the lower half, the BFO control would provide the missing half of the carrier waveform, technically giving you two channels on the one carrier frequency? - too lazy to google.

righto, had a wiki-peek and saw my understanding was slightly off, mind you I was about 11-12 years old when it was explained to me. http://en.wikipedia.org/wiki/Single-sideband_modul ation [wikipedia.org]
