The New America Foundation — a think tank self-described as investing in, “new thinkers and new ideas to address the next generation of critical challenges facing the United States” — hosted a forum on broadband in the US.
Here’s a quick description from an email I received from the group:
On Monday New America’s Wireless Future Program hosted a policy forum highlighting the critical need for developing an affirmative national broadband strategy to keep the U.S. prosperous in the 21st Century. We also released a new Issue Brief, by NAF’s Benjamin Lennett, that explains how unlicensed access to TV band ‘white space’ will give a big boost to rural broadband.
Here’s a link to a PDF of the report’s executive summary.
Update — this post was initially only going to cover the NAF forum, but here’s some interesting broadband news via KurzweilAI.net:
Time reversal allows wireless broadband under the sea New Scientist news service, June 25, 2008 Researchers at Scripps Institution of Oceanography and NATO Undersea Research Center have developed an “acoustic time reversal” technique that boosts underwater wireless broadband speed by up to three times, or extends the range up to 3500 km.
The system compensates for reduced signal/noise ratio due to phase-delay artifacts from surface and sea-bottom echoes. A receiver first transmits an acoustic carrier signal. The sender then time-reverses what they receive, and also modulates the signal to carry a message.
