My summary, beamforming plus wider bandwidth. His white paper probably addresses the more inquisitive and technical readers' questions: http://www.rearden.com/DIDO/DIDO_White_Paper_110727.pdf http://www.rearden.com/DIDO/DIDO_White_Paper_110727.pdf 802.11ac beamforming justs boosts signal quality. It does not take advantage of more bandwidth. I don't think the math is actually that complicated to explain. I think of it as the electromagnetic equivalent of visual cryptography: http://datagenetics.com/blog/november32013/index.html http://datagenetics.com/blog/november32013/index.html An antenna not integrated into the system would see noise. The designated phone would see the exact interference pattern it needs to get the "picture."
