Have you guys heard about pCells? They're supposed to revolutionize cellular:
This might be bigger than we think, though. With this kind of technology, which can be easily deployed, the possibilities go beyond watching 4K video in crowd:
But with Artemis:
- You could use beamforming instead of beamsteering, eliminating the cost of traditional approaches.
- The power being transmitted would be split among hundreds of antennas, each of which is individually not transmitting harmfully high levels of RF energy. At the location of the receiver constructively interferes to add up to the necessary power required, and everywhere else the radio waves just add up to noise.
- The ability to focus the radio waves to a sphere of energy just a cm in diameter means potentially that little energy will be wasted, and it's safe to use around humans (assuming the receiver itself is a cm thick).
Whoa.
