NC Governor Allows Anti-Community-Broadband Law
zerocore writes "North Carolina governor Bev Perdue will not veto a bill that will limit small town municipalities' ability to create community broadband when private industry will not go there. 'The governor said there is a need to establish rules to prevent cities and towns from having unfair advantage over private companies. But she said she was concerned that the bill would decrease the number of choices available to consumers. The bill would require towns and cities that set up broadband systems to hold public hearings, financially separate their operations from the rest of government operations, and bar from them offering below cost services. They also couldn't borrow money for the project without voter approval in a referendum.'"
Right. More public projects should have to comply with requirements like these. Transit systems being an excellent example.
Transit systems are a completely different beast. The cost savings for the city are only found when you look outside the system. More productivity when workers can get to work because they aren't in traffic. less road rage. less accidents. less emergency runs for car accidents meaning police have more time for looking for criminals. less road repair. Firemen putting out fires instead of carrying the jaws of life to cut some guy out of his SUV rollover.
If you don't understand how the system works, go to New York. Or Shanghai, or London. Just try owning a car in one of those cities.
Finite wireless spectrum?!? What are you talking about? Let's talk Mhz:
There is Ghz spectrum between say, 2.4 and 3.4 Ghz, which seems limited. So you might break it out into 1 mhz bands, giving you 1,000 usable frequencies. Or break it more finely,into .1 mhz bands giving you 10,000 usable, or .01 giving you 100,000 frequencies, or...
A 0.01 MHz band does not give you much capacity, perhaps something of the order 0.1 Mbps. While bandwidth is not the same thing as data rate, they are proportional.

Spread spectrum technology, first developed by military for secretive radio communications, send information in short bursts in pseudorandom frequencies. This frquency hopping allows for far more efficient use of existing radio frquencies with minimal disruption. Numerous studies show this type of technology could extend the available bandwidth a billionfold or more.
By definition, spread spectrum uses a lot of bandwidth ;) The problem with data rate is that when everyone uses spread spectrum, noise floor goes up, and thus the signal/noise ratio gets worse. This, in turn, means a smaller data rate per bandwidth, as explained by Shannon.
Escher was the first MC and Giger invented the HR department.
