I’ve been super busy lately, but I’ve been meaning to delve into this announcement more deeply. Unfortunately there’s not really a lot of information out there other than a PDF file available (after the break.) Basically this DIDO proposal is for wireless clients to connect to wireless access points, but with a customized waveform, computed at a datacenter, designed to maximize throughput in a given area. This boils down to an interference mitigation strategy but I’m not sure that this is the way that Rearden Labs would like for you to think of their ultimate technology. To me, I also don’t believe this has been fully thought through, but there is a portion of the idea that is interesting to me. This interesting part is where a data center manages the waveforms. It’s not practical but interesting. 

This is nitpicky but the author of the paper clearly either doesn’t understand wireless technologies with the numerous incorrect references or doesn’t care to engage anyone that knows anything and is only focused on selling. Anyway I do applaud the out of the box thinking.

Rearden Wireless™ is excited to introduce a breakthrough in wireless technology:

Distributed-Input-Distributed-Output (DIDO) Wireless Technology

DIDO technology is a revolutionary approach to multiuser wireless that provides each user the full data rate of shared spectrum simultaneously with all other users, by eliminating interference between users sharing the spectrum. As a result, DIDO profoundly increases the data capacity of wireless spectrum with sub-millisecond latency, while increasing reliability and reducing the cost and complexity of wireless devices.

A New Approach to Multiuser Wireless

Distributed-Input-Distributed-Output (DIDO) wireless technology is a breakthrough approach that allows each wireless user to use the full data rate1 of shared spectrum simultaneously with all other users, by eliminating interference between users sharing the same spectrum. 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. 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.

The potential of DIDO is to have unlimited number of simultaneous users, all streaming high-definition video, utilizing the same spectrum that a single user would use with conventional wireless technology, with no degradation in performance, no dead zones, no interference between users, and no reduction in data rate as more users are added.

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.

This paper describes how DIDO is dramatically different than conventional wireless technology, how DIDO works, what we have running so far, and the mind-blowing applications DIDO makes possible.

We believe that DIDO wireless will completely transform the world of communications and far more.

Small Cells

Small Cells, previously known as 'femto' or 'pico' cells are possibly a savior to network operators. They offer capacity and coverage to the end user and are inexpensive for the network operator. Why aren't they everywhere?
