Four admirable spectrum licensing wonks have started an advocacy site on low-frequency unlicensed wireless: Kevin Werbach, Andrew Odlyzko, David Isenberg, and Clay Shirky are a combined powerhouse of intellectual might and regulatory expertise. Their site promotes the notion of unshackling spectrum below one gigahertz from outdated technical notions that restrict innovation. The FCC has become more and more amenable to these ideas, as it toys with rulemaking vastly different than anything that's come before.
The site is funded by Microsoft. I had some back and forth with Werbach about what that means, and he has clarified the issue on their About page. Microsoft is funding their time to devote to the issue, but the editorial voice is independent. I know all of these gentlemen except Odlyzko, and can vouch that you wouldn't see the door hit their backside if there were a conflict of interest or an attempt to change their statements.
