PCell

As we become more and more reliant on mobile Internet-connected devices, bandwidth is becoming an increasing concern. Start-up Artemis Technologies (founded by QuickTime and WebTV creator Steve Perlman) hopes to fix the problem of poor signals with PCell, a "personal cell" that lets every mobile 4G device get full signal strength.

That's done by deploying a large number of small devices rather than a fairly small number of cell towers. Though the technology is still experimental, Perlman touts PCell as being capable of increasing signal speeds 1,000-fold.
