TV-Band White Spaces Database Providers list officially released
One year after the proposals by TV-Band white-spaces database providers the FCC released recently the next steps in this matter. As it was expected the FCC opted for license the spectrum database to multiple providers:"While the operation of multiple database administrators may present some coordination challenges, we find it is in the public interest to have multiple parties developing business models for this new mechanism."
It results that all the proposals from last year have been "conditionally" selected:
- CommSearch
- FrequencyFinder
- KB Enterprieses/LS Telcom
- Key Bridge
- NeuStar
- Spectrum Bridge
- Telcordia
- WSdB
"we are designating the database administrators subject to a number of conditions, including that they attend workshops to be conducted by OET and perform real-world testing of their databases to ensure they provide accurate results before they are made available for use by TV bands devices"

Hi Gonzalo, I just have found your blog and its really informative and helpful. I study CRs as well, and this is my first time getting introduced to the internals of the wireless communication technologies. The more I study about the history of wireless standards and its evolving nature, the less I believe in the future of CRs. (No offense! I need to fulfil the requirements of a PhD about CRs as well.) Let me put it this way: There are various technologies (IEEE 802.11, 802.15.1, 802.15.4, 802.16, 802.22, etc.) working on the ISM band in an uncoordinated and non-cooperative manner. Consider a case where there are 3 WiFi APs operating in the ISM band and we all know that they are almost oblivious to each other and incapable of fully utilizing the available ~80MHz of spectrum. You might say that there are various industrial WiFi providers providing a centrally managed network of WiFi APs for such scenario. Yes, there are, but they don't work that well as advertised. Think about what happened in the presentation of iPhone 4 in 2010. ("Because there are 570 Wi-Fi base stations operating in this room. We can't deal with that." -- Steve Jobs) At TechCrunch 2008, RailsConf 2010, Web 2.0 Expo 2010. These giant conferences and public events are equipped with centrally managed and professionally placed >500 WiFi APs, and they just didn't work. On the other hand, take look at GSM. We are not capable of making a stupid WiFi network work in ~80MHz, but a GSM operator is able to serve "millions" of its customers in just ~25MHz. To sum up, my prevision is that: When we manage to finalize a standard for CRs and in the progress of introducing it into the market, GSM will be serving up to %90 of the internet connectivity market in a much more effective and successful manner. (Please, make me wrong.) It just seems to me that we are trying to clean up the mess of a bunch of uncoordinated big-brother company activities, which will just inevitably get lost in the dusty pages of the history in a near future. Here is another example: For decades people worked on sensing and now FCC tell us that let's forget about that sensing and use a GPS database. Sorry but.. WTF! I really would like to hear your opinions on these matters.
