Wireless System Could Offer a Private Fast Lane

The pCell spatial demonstration [1] is really amazing. If this delivers what it promises, we could finally have the technology we needed to cut the cord entirely for personal/business Internet access and to no longer be at the mercy of Comcast/TWC/Verizon to deploy the last mile. That is, if we aren't just trading one despot for another.

Sounds kinda like CDMA. Anyone have a more technical description?

I've been looking for a technical explanation as well. The best I've found so far are a host of the patents ostensibly associated with pCell implementation [1], [2], [3], etc.

[1] System and method for DIDO precoding interpolation in multicarrier systems https://www.google.com/patents/US8571086

[2] System and method for adjusting DIDO interference cancellation based on signal strength measurements http://www.google.com/patents/US20110002371

[3] Systems and methods to coordinate transmissions in distributed wireless systems via user clustering http://www.google.com/patents/US20110002371

[3] is https://www.google.com/patents/US8542763 , you pasted [2] twice.

These are quite readable; worth a look. Thank you, ashwinl.

Looking at the diagram (http://cdn.androidcommunity.com/wp-content/uploads/2014/02/a...) It looks like nothing more than beam forming antennae.

Which is what 802.11n does.

So this looks like some very sexy marketing, and little else.

"data centers connected to the antennas perform fast mathematical calculations to create a unique and coherent wireless signal for every person on the network" -OP
