Over at his always-informative Spectrum Blog, wireless guru Michael Marcus brings to my attention a new report that will definitely be of interest to everyone here about "The Economic Value Generated by Current and Future Allocations of Unlicensed Spectrum." It was written by Rich Thanki of Perspective Associates, a UK consulting firm. I haven't had time to finish the whole thing yet, but it basically lays out the argument for opening up more spectrum, especially "white spaces," to unlicensed use.
Anyway, Mike Marcus has an much better write-up of the report than I could ever do, so head over there to check out his discussion. One important thing that Mike stresses is the importance of technical flexibility:
But the key issue here is not the presence or absence of a license, the key issue is deregulation. A major reason why unlicensed networks have been so innovative is that the descendants of the FCC Docket 81-413 rulemaking, e.g. Wi-Fi, Bluetooth, and Zigbee have been in spectrum bands with great technical flexibility... If you overregulate unlicensed systems, they can stagnate just as much as licensed one often do.
