I spent all day reading this discussion, one of the few things that I wonder is why many of techie wifi people on here don't think about getting an Amateur Radio License
Having an Amateur (Ham) License not only allows you to try some of these wifi experiments using real powere--more than a watt, but it also grounds you with some understanding of RF propagation, RF theory and some understanding of rules and regulations in regards to wireless communications.
Try going to a local ham club meeting. Talk to some of the people there and you'll find a wealth of information. They aren't all old guys talking to people on morse code. There are some pretty cutting-edge things going on in the ham bands and you may find experiences there help you out in other places.
An Amateur Radio License also tells others you know what you're talking about. It is a very technical hobby and compliments computers and the internet quite well.
The FCC does more than hand out frequencies like a domain name registrar hands out web addresses. They do actually enforce the rules and regulations and type-approve equipment. Getting rid of the FCC is foolish without an in-depth plan of how you plan to accomplish many of the tasks they do. Sure the FCC has it's problems, but I'll tell you, from what I have read today; I have a better appreciation for the FCC after reading some of the stupid ideas some people on here have had to replace it.
The Radio Spectrum is a natural resource owend by everyone. The FCC's job is to manage it.
You can argue that the FCC isn't doing their job well, however PLEASE do not advocate giving away my stuff... I feel the Radio Spectrum is mine --- as it belongs to everyone. It can not be sold or auctioned, however the right to use a certian part of it in a given geographical area for a given time may be.
Next thing you know people like you will start selling air and I won't have any left to breathe. Some things are better left to everyone.
The FCC is more than a registrar, they also make sure that devices transmitting on RF don't kill you. Would you like to have little johnie microwaved -cooked by his R/C car?
My point being however, that there is no fundamental reason to treat the RF spectrum different than land use on earth
UMMM
Oh boy, Umm where to begin.... Well lets see lets start with wavelengths under 30 MHz or with longer wavelengths than 10 meters... these wavelengths often travel around the world --- THERE GOES YOUR FUNDAMENTAL REASON
Frequencies from 30-3000 MHz can travel along weather fronts for hundreds to thousands of miles... bounce off aurorae reflect off of the moon and originate from satellites. THERE GOES YOUR FUNDAMENTAL REASON
Radiowaves travel outside geoplitical boundries into different regions states counties and countries. THERE GOES YOUR FUNDAMENTAL REASON
Far as I can tell YOUR FUNDAMENTAL REASON IS STUPID
The FCC should be reorganized --fixed or replaced, however most of what it does in very important stuff. Remember we also have international treaties regarding the RF spectrum we are obliged to follow.
I would think the issue has more to do with the doppler effect.
WRONG
It's highly unlikely the doppler effect would have anything to do with it. What you fail to see is you are talking about radio waves that travel at the speed of light, not sound waves. The frequencies and the bandwidth used mean that you would need to be going a whole hell of a lot faster than 100 mph to make a difference.
Differences in the tolerences of the parts used in cellphones will have more of an effect on the frequency of the signal than a doppler shift would, even in an airplane. Now satellites in the sky in non-geosynchronous orbits or other spacecraft will have quite a noticable doppler shift. If you listen to the beacons on some of the OSCAR sats, you can hear the tones change as the bird flies over. This will not be the case on a cellphone in a car.
You would more likely get "picket fencing" in the signal this is a rapid fluttering sound as heard on an analog FM signal. This is a rapid fluttering sound caused by multi-point reflections of a signal. As you travel the signal is bouncing off everything around you and the signal strength veries a lot. Even though your signal is a digital signal it is sent via radio waves. the digital signal is very robust, however when the signal to noise ratio drops below a certian level and the signal degrades enough, it just drops off. ---This will sound exactly the same to the listener as when you are in an area with low signal strength and the signal just drops off.
Some airlines are implementing onboard picocells so that passengers can connect to the airplane's own cell phone 'network' and avoid problems due to doppler effect.
NO. This is to avoid problems as a cellphone in a plane would constantly be changing from cell to cell as a plane flies over. If you put a cellphone in a plane it can probably see (and hit) every cell in a state or more. as the plane moves different cells would be preffered as the topography, altitude, airspeed, troposheric conditions are changing. This can cause all hell to break loose on a cell network where differnt cells are constantly voting in over a VERY large geographic area.
Your cellphone will actually work great on a plane. Try adding several hundred to a few thousand cellphones working all at the same time in the friendly skies and watch the cell network choke.
It is also possible that cell phones do interfere with some onboard control things..
Bingo! Nothing like releasing a whole lotta RF into a faraday cage (the signal can only get out of the plane through the windows) to screw up other electronics. Granted the amount of interference a cellphone will have on the electronics of a plane is minimal, you must understand that a minor problem with the navigation or control systems of an airplane is never minor.... There are no minor problems on airplnes... Since you could end up flying into the ground at Mach.8 ! Also, 1 phone on a plane is onething put 400 phones at 500 miliwatts each all transmitting and that's like running your microwave oven with the door open!!!!
It looks like they want $9,000.00 for this thing.
It looks like a whole lotta fun in a shiney black box, but I don't think there is enough good stuff on TV to have the need to record 7 different things at one time.
BUT... It could allow you to access Cable, Satellite, Over-The-Air Broadcast possibly High-Def and standard, maybe 7 tuners is about right??
I wish the site wasn't so slashdotted, I was barely able to get to the price and then I started getting server errors. I'll have to remember to check back later.
For a man to have ethics and morals, he must decide to have ethics and morals.... You can not adopt all models of ethics and morals and be an ethical and moral person. To do so is an oxymoron, just as you are a regular kind of moron. There are no shades of gray. Shades of gray are a cop-out for the ethically inept.
Cheap stabs about the ethics of the president do not help your argument, it only shows the depth of your depravity. People like you should think before you open your mouth.
Next time keep your mouth shut before you let all the stupid out.
No, you still miss the point. It doesn't matter if you use an extreme example or something "in the gray" the point is there is not gray if you have any morals.
What is so difficult about wrapping your head around the idea there is right and there is wrong? Causing annoyances for the sake of causing annoyances is unethical and immoral no matter how slight. Don't you see degree isn't the issue! You should see that the problem is with the entire concept.
I don't think it follows that needing a salary so that one can feed one's family is equivalent to being morally challenged. I'm not sure if you have children or not. But if you did, would it be moral of you to turn down a marketing job in a tough economy?
If you had morals, you would realize that the ends do not justify the means. Just because your children are hungry does not automatically give you carte blanch to set your moral aside. In fact doing so only proves you never had any morals to put aside.
Character means you find a way to feed your children without being immoral or unethical. Saying there is a tough economy and you had no choice just shows the quality of your character.
What a man does with his life is not nearly as important as how he does it.
Why does this just cause a picture in my mind of someone's long lost childhood friend showing up at your door after being kicked out by his wife and broke with no job?
I know that isn't what it's all about, but that was the the first picture that popped into my head.
I would think that artificial gravity, inertial dampers and warp drive would all be closely related. Since it may be likely that in order to create gravity (or counter act it) you may have to warp space.
It may be likely if any one of these technologies were to become practical, so will the rest.

Tell them to use Skype."
From "Skype's Website:...Skype, created by the people who brought you KaZaA"...
I can tell you that being brought to me by the same people who inflicted kazaa on the world sure instills a lot of confidence... Does is come with the b3d projector and save now????
Sorry, Schernau's Law tells us that your post has no value, that you probably use AOL, own an X-box, and are as bad as the trolls, since you used the word 'puter' in your post.
My law says you sound like a little bitch with taped-together glasses who keeps getting beaten up too much. How does it feel to have yourself become the TROLL???
...and Coca-Cola found itself in when Pepsi came on the market.
Pepsi-Cola was founded in New Bern, NC, in 1898.
Many of PepsiCo's brand names are over 100-years-old, but the corporation is relatively young PepsiCo was founded in 1965 through the merger of Pepsi-Cola and Frito-Lay
I remember the big Coke -vs- Pepsi thing was in the very late 1970s to early/mid 1980s.

Sounds like APRS
Current is how much food is available
Voltage is how fast it's shoved down your throat
Which would make Wattage crap as it is the product of the two
It was printed on an EPSON Printer

Normally I would be against just getting out the restore disc and starting over... it usually just causes the problem to come back later.
In this case I think it's a good idea. I'd hate to have to go to Mars to make a housecall on a sick puter
