In Kathryn, ND. Where my wife is from, there is no cell phone available because of the Sheyenne river valley. They are too low to get reception from Valley City, ND. They do have land line telephone service and electric power. I believe it is a political and financial thing of which I have a brain blockage for understanding.

That, plus people like Vonage, Time-Warner and other VoIP folks who are selling their digital phone service to those who have high-speed internet, means you don't have to have a phone at home, anymore. Long distance charges are basically a thing of the past nowadays, with the advent of cell phones, and digital VoIP stuff.. the internet. I've thought about that - install it on a laptop, get a cellular modem for said laptop and when you're down for the day, if you're traveling, you can sit down, crank up your laptop and your webcam and have a live video conference with the spouse-mate, or whomever. EVERYONE however, still relies on electricity in their homes, so that's why the big push is on to get everyone (as much as possible) on high-speed internet. I think that it should be noted that sending voice over RF started (of course) with that group of Amatuers back in the days of Edison, Feseden, Watts, Tesla and others. After the video thing started, Hams started trying to figure a way to do it over radio. Now, thanks to the groundwork laid out by Hams, most "Instant Message" chat programs available (MSN, Yahoo!, ICQ, AIM, are the top four popular) allow you Voice and Video, at the same time. The technology is here - it's just trying to be implented across the nation without regard to the rest of the spectrum. I personally don't see why the Satellites don't carry the broad-band signals, since they've got cameras that can see pretty much in your house, from 22,500 miles in the air. It wouldn't be anything to 'piggy-back' the digital broad-band signal to whoever has a recieving device, anywhere on the planet. There's no need for money to be involved in Internet access, anymore. It can be done over the air, just like radio... it just needs to get a bit higher in frequency. Keep it up in the 5.4 to 9.5GHz range - that way there's plenty of bandwidth for spread-spectrum stuff, and there's no threat to HF communication. --- 73 = Best Regards, -Geoff/W5OMR ______________________________________________________________ AMRadio mailing list Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected]
