The patent covering OnLive CEO Steve Perlman's amazing new wireless tech

Steve Perlman was right, when talking about asking the right questions. The way this amazing new wireless tech works is that it actively cancels out interference at the transmitter, instead of just maximizing the received signal, it's a creative new way to look at the problem of channel utilization.

It's a form of spatial multiplexing, with some additional math on top of it. They derive a set of coefficients describing the channel from every transmitter to every receiver. Then they tweak the values of the channels in a matrix such that they aim the nulls in transmission for a given channel at receivers who don't want to receive it.

This allows you to send more signals to those who want it, while avoiding sending it to those who don't want it. This is done with multiple transmitters, to multiple receivers, all at the same time, and the coefficient matrix is kept updated along the way.

Channel capacity is proportional to S/N. If a single transmitted signal is 20 db over the noise floor, and you can reduce the level of interference below that value, you could get 100 times the original bandwidth for a given system and this tech can do just that.

OnLive Founder and CEO Steve Perlman officially names his amazing new wireless tech
DIDO => Distributed-Input-Distributed-Output technology. More info about DIDO is here and here.

Here's a detailed explanation of how DIDO works.

You can watch a video of Steve Perlman's unveiling of this amazing new wireless tech here and Rearden already has plans to spin-out a company based on this amazing new wireless tech.

Here's the link to the patent, enjoy reading it.


  1. You're slowly beginning to become extremely useful for news John, keep this up and you may put Onlivefans Articles out of buisness. :)

  2. yeah great coverage man! I used to use onliveinformer, and now i use onliveportal, but onlive spot seems to be the upcoming site for best coverage!

  3. Are there any side effects or is this the optimal solution in all possible scenarios (incl. ones that optimize for a single user close to a base station)?

    Will have to wait for Rearden to show their practical implementation of this tech, i mean hardware and facts. These are only patents so far, but when someone like the OnLive founder says they can do it and they have working hardware, one can say they are up to something.

    Current info points toward no side effects and only benefits, but in practice it's usually different.

    We'll just have to wait and see. They plan to spin-out a company on this tech soon. This info is in one of my other articles.

  5. My interpretation -
