Hey, Kurtis Heimerl here. This work seems to have gone though the telephone game, so I thought I should make some slight corrections to the original (down?) sharable article. Firstly, I'm not a professor, I'm a graduate student (https://www.eecs.berkeley.edu/~kheimerl/). Secondly, there wasn't enough mention of everyone involved. This project is an offshoot of the fantastic OpenBTS work done by David Burgess et al, now working under the Range Networks (http://www.rangenetworks.com/) banner. A lot of work on the open source projects have been done by Alexander Chemeris and Thomas Tsou, and they should be given credit as well. Lastly, the project is still under heavy development. It's worth noting the "prototype" used by Mobile Active had no clever power tricks, and was just a software modification of OpenBTS. We'll have something more substantial soon.
Past that though, I'm happy to see people quickly understand what we're going for here. Great to know others think your work is interesting. We'll also be deploying a sample "BTS Application" at burning man this year. Check it out: (http://tier.cs.berkeley.edu/drupal/burningman)
