FCC Pitches Free, Bowdlerized Wireless Internet Access
Aidtopia writes "FCC Chairman Kevin Martin is proposing auctioning off an unused part of the 25 MHz spectrum on the condition that the winner provide free wireless Internet access. The proposal sets coverage targets that ramp up to 95% of the population within 10 years. The catch: the provider must filter out obscene content." I wonder what definition of "obscene" the FCC would like to use.
This isn't the 25MHz spectrum, it's a 25MHz block of the 2.1GHz spectrum. Realizing that makes this story make a whole lot more sense. There's no possible way this would work in the HF range.
I agree with your concern. If we assume an S/N ratio of 20db (about 3 S units on my HF rig or noise at S6 and signal at S9 which I consider a good copy) then Shannon-Hartley's theorem says that they will get at best 333kbps. I used the example calculation #1 at http://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theorem and just substituted 50kc for 4kc to get this.
Anyone disagree?

Sure. "s/obscene/dissenting/g" means "everywhere you see 'obscene', substitute 'dissenting'". It's the syntax of the Unix ed text editor; see this page for details.
