At 66 miles, a 60% Fresnel zone would be around 195'. At 66 miles, the curvature of the earth would be about 160'.
Combined, for a 60% fresnel, you're looking at antenna heights (center of radiated power) at about 160 + 195 = 365 feet.
However, if the angle at which the 10 story building was 'looking' high enough up to the mountain top, they could have made it, but at 66 miles, I doubt it. There was no doubt some measure of reflection/refraction of the signal by terrestrial objects.
365' of height is not that hard to get past if you can find the right two mountains.
Now, to the Maine Atlas for me to find those two mountains!:)
A colleaugue of mine, former cow-orker, just blogged about his experience in his brand new job being a network admin of a college in Maine. Turns out that his switches have a feature called "source blocking" which allows them to disable clients on MAC layer level if a client makes too many unresolved ARP broadcasts. He just outputs the list of clients to a web page taht the tech support desk can respond to when students call in and say "Hey, I can't get on the Internet, is it broke?" the helpdesk says "YEs, you're either scanning the network or infected by a virus. Fix it." And the latest batch of virii are stopped in their tracks.
1. allow employee to work on linux code from work and from home 2. deny that he had permission to do so or you didn't know he was 3. make up license scheme 4. profit!
Now, instead of everyone ranting about ADD/ADHD and whether it's real or not, let us just link to the old article where it was ranted about last month:
The laws surrounding it are rather simple if you just know a few things about how to calculate the signal strength between points (or point to multipoint).
Was your friend busted by: The FCC? His ISP he was sharing bandwidth from against his AUP? His employer for sharing bandwidth without their knowledge?
Given a decent population density, a WISP can certainly be a viable solution, especially in moderately dense rural areas - like old town centers with decent business districts - where the DSL companies and cable modems have not yet tread. And to save money for point to point links - nothing beats paying once for hardware and never paying monthly fees forever.
I think the reviewer is one of the same people that left me some feedback on eBay.

How? They can afford lawyers. College students can't. It's really quite as simple as that. Set the precedent in the court with someone unable to defend themselves and then you can start getting the bigger fish. The same thing happened with Divine, Inc. . Thing is, Divine went Chap 11. So whoever buys their property will do it all again. Lucky us.

Well for OReilly books you can, sort of: http://safari.oreilly.com/
Your point is taken on the 'books, highliter, no Internet luring you to procrastinate';) same thing here. Shelf full of OReilly's to use when necessary.
I'll summarize it again as I have in other forums.
- My laptop sees a signal and requests access to the network by asking for a DHCP address. - Access point sees my request and GRANTS me a lease on an IP address with which I can access their network - I surf using the network - I leave.
I asked, they said YES. They could have easily denied me, but they invited me into the network when I asked if I could. There are SO MANY different ways to keep people out, that owners of AP's just have to do something to secure themselves. Shame on them if they fail to do that.

Rival? Sorry, surpass is the word you're looking for. Granted, TTT was made with newer technology than Episode 2 (or is that 5?) but the effects in TTT surpass those in Ep. 2.
I also expect to see even better effects in RotK, to which I'd expect to see significant improvements from Lucas when comparing Ep. 2 and Ep. 3!

And the price to mail the same exact size and weight envelope to the guy next door?
And in the town I work in (and I think in most of the state) ALL mail, every single frikkin piece of it, goes to one town in the state, then gets sent back out. EVEN IF ITS LOCAL! So when I send from 04901 to 04901, it goes down to 04054 (or whatever) even though it's local. I suppose that's why my local mail is the same exact cost as the one that goes 3500 miles. They put the same effort into it.
The USPS is incredibly inefficient. They're unreasonably expensive and they offer no guarantee ever on any of their 'priority mail' yet they ALWAYS compare it to 2-day shipping from the other carriers. And priority will take 'from 2 to 3 days - sometimes more'. It's not guaranteed 2 to 3 days, just 'it usually takes...'.
> Now if you only had a telephone and a broadband > service like that...
Well the reliability of my broadband seems like they take their example from the USPS. At least it's not cable based ( adelphiasucks.com ! )
And for my email, it costs the nothing to send email to friends in California and around the world or even my good friend BARRISTER JOHNSON ATTANGAH who has $24 million dollars he needs to move out of Nigeria immediately!
I'm terribly unimpressed with the USPS. The good thing is that they DO bring mail to rural America, which is a good thing. OTherwise, independent companies would likely start charging based on 'edge of the world' rates for delivering to 'east bumf$%^, kansas'. [my apologies to anyone living in east bumf$%^, kansas']
It's true that breweries in America actually produced bottled WATER during the era of prohibition and some have bottled water in emergencies in modern times as well. It's also true that most of the mass-produced beer from the big breweries (AB, Coors, etc) is pretty boring. Even for a pilsner it's boring.
However, since about the 80's, we've seen a great resurgence in the brewery world which makes comments like 'American beer is fucking close to water' show the speakers ignorance of American beer today. Yes, there's a bunch of breweries making foofy fruity beers too, but there's a significant number of breweries that serve up cask conditioned authentic ales served at the right temperature and served from a beer engine rather than a tap.
So, you might want to reconsider your ignorance and try some beer that's not mass produced, yet still American and damn tasty to boot.
