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

ashwinl2• 12 years ago

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.

"a pure software-defined radio C-RAN" http://artemis.com/pcell

"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

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.
