This sounds basically like pumped up MIMO, nothing that is not already known, just not implemented due to limitations of devices. As an example from the whitepaper: "AP 1 and AP 2 both transmit their respective radio signal waveforms simultaneously." The most difficult part here is the syncing of the transmission. It really has to be precise almost to the sample level (10-0.1ns time window for the transmission to start on both devices depending on the bandwidth used). And syncing clocks on remote devices to this precision, not to mention maintaining the sync is very, very hard. And this is just one obstacle this guy has to solve. In addition if the users move the waveform has to be recalculated, on worst case even if the users do not move the radio environment has already changed (due to other things moving) before the old optimized signal has been sent. This makes it necessary for the signal calculations to be local to the device as latencies to remote devices are way too high in order to update the waveform fast enough. However on stationary receivers this problem is not as bad as on mobile ones. These were just few of the problems with this guys approach which sprung up to my mind when reading the whitepaper.
