Steve Perlman Releases Whitepaper on Wireless DIDO Tech

OnLive's director of corporate communications Brian Jaquet informed us last night that OnLive CEO and founder Steve Perlman completed his whitepaper (PDF) in regards to the new DIDO wireless technology. He also gave a sneak peak of DIDO at the Columbia Magill lecture in early June which can be seen in the video below (starting at the 28th minute).

As we reported earlier this month, Perlman has seemingly broken Shannon's Law with his Distributed-Input-Distributed-Output (DIDO) wireless technology. Created at another of his startups at parent company Rearden Companies, it's an experimental wireless communications system that promises to pipe a full wireless stream from a nearby cell tower no matter its current load, whether its 100 simultaneous users or a 1000.

"Distributed-Input-Distributed-Output (DIDO) wireless technology is a breakthrough approach that allows each wireless user to use the full data rate of shared spectrum simultaneously with all other users, by eliminating interference between users sharing the same spectrum," reads his abstract. "With conventional wireless technologies the data rate available per user drops as more users share the same spectrum to avoid interference, but with DIDO, the data rate per user remains steady at the full data rate of the spectrum as more users are added."

"As a result, DIDO profoundly increases the data capacity of wireless spectrum, while increasing reliability and reducing the cost and complexity of wireless devices," he continues. "DIDO deployment is far less expensive than conventional commercial wireless deployment, despite having vastly higher capacity and performance, and is able to use consumer Internet infrastructure and indoor access points."

Ultimately the goal of using DIDO is to allow an unlimited number of simultaneous users, all streaming high-definition video, utilizing the same spectrum that a single user would use with conventional wireless technology. There will be no degradation in performance, no dead zones, no interference between users, and no reduction in data rate as more users are added. Sounds impossible.

"I know that sounds impossible," he said earlier this month, "but literally if you have a cell that has 100 megabits per second worth of bandwidth in it and you have 100 people, each person gets 100 megabits a second. It’s really pretty amazing; you don’t interfere with anybody else."

He added that DIDO works indoor/outdoor for urban/suburban applications at distances of several miles, and for rural applications, DIDO works at distances up to 250 miles. Urban/suburban latency is sub-millisecond.

Will DIDO wireless completely transform the world of communications as we know it? The proof is in the pudding as they say. But so far we're pretty dazzled by what he's accomplished with OnLive, allowing us to stream HD PC gaming on a low-end laptop and soon a tablet and smarphone.

For those interested in learning more, Perlman's paper describes how DIDO is dramatically different than conventional wireless technology, how DIDO works, what the team has running on DIDO so far, and the "mind-blowing" applications DIDO makes possible. Also check out his sneak peak, seen below.
