Re: Won't do any good in the Hills of WV. Sounds like in your location they would need an extremely tall tower on top of one of those hills. The provider will have to hash that out if they want to provide for your community. 5Ghz is definately line of site comms, but as I said if your antenna has line of site with the tower it will work, even with low power. Here in the front range of the rockies, 10Ghz can go for 100 miles as long as they have line of site to each other. That means one station going to the top of the mountain and the other station can be anywhere on the plains that has line of site to this mountain. It works. |

Saugus, MA | 100-miles at 10 GHz isn't realistic. The practical limit at 10 GHz is on the order of 12-miles, even if you use 8' diameter parabolic high-gain antennas at each end. The problem is attenuation when moisture or rainfall is present. See this thread for a more detailed explanation (»Back to technical reality...). |

Longmont, CO | Yes I agree in some geographical regions it is like that.
However out here in the rocky mountain front range area it is always very arid and with 14K ft. mountains to have one end is always a plus. The rocky mountain microwave group has made contacts on 10Ghz beyond 100mi. The point being that the 5Ghz band is doable in most areas as long as they have line of site to the providers antenna. Yes reflections would present problems in some installations, but it would be the provider who would make sure this is corrected in any installation. So it would be very expensive to the provider to customize each and every installation. They would have to do a survey of each potential customer site and then go from there. Similar to DTV |

You should try to set up one of those towers on a ridge line. Anyone that owns one thinks every little tower that goes up has a cell company behind it, and a $3500.00/month budget to pay for it. I operate a wireless ISP here in the Mt's of NC (Mitchell/ Yancey Counties) and it is very difficult to get through the foliage, hills, and costs of setting up. |
