News and commentary on cognitive radio
Keith just pointed out to me that he’s posted a google map of their earlier spectrum campaign.
Going all web 2.0 for a moment, what I think would be really cool for the CR community is if we could put together a collaborative spectrum sensing google map so all of the varying measurement campaigns could be synthesized together into one usable super database.

According to the WaPo, new rules for Block D have been issued:
Under the new proposal, the network would be auctioned as one national block of radio spectrum or, alternatively, as 58 separate regional airwaves licenses. The agency said that it prefers to sell the spectrum as a whole and that it would give priority to such a bid. But if no one meets the minimum reserve price for the national block, the commission would close the auction with a minimum of half of the 58 regional licenses sold.
…
To attract bidders in a new auction, Martin said yesterday that the minimum price to bid on the network would drop by nearly half, to $750 million. The deadline to build the network would extend to 15 years from 10 years, and any lease charges from public safety officials would be capped at $5 million a year.

Michael Marcus points to a series of papers released by the FCC on management and efficiency tradeoffs between licensed and unlicensed users.
I’m busy this week, but I might try to give my two cents on the papers next week.

Emerging Networks has a series of posts reporting results from spectrum occupancy measurement campaigns.
In this entry, they discuss the results of measurements taken during during Keith’s and Tom’s whirlwind tour of America.
In this entry, they report measurements from a drive across Ireland
Here they report measurements from Dublin.
Finally, in this post they discuss results of a campaign in Dublin performed by Shared Spectrum.
