I need to break the "radio silence" ... I've been pretty busy with administrative projects and travel, so blogging has taken a back seat.
I have been working on dynamic spectrum access (DSA) for a number of years now. A paper on one of my projects, together with Arnon Tonmukayakul, is coming out in Netnomics shortly. In addition, I presented a paper on DSA and the FCC White Spaces decision at the recent iConference. Hopefully, the papers will be made available soon.
So, given this, I found this site to be of interest. You can use it to find the TV white spaces at a particular address.
If you go back through this blog, you'll find that I have been interested in (OK, critical of) comparative studies of broadband penetration. So, I found this site interesting, which looks at broadband from the point of view of connectivity rather than penetration. From this perspective, rankings (for what they're worth) look quite different.
