    We have a mostly solar powered analog extender site that covers Death Valley National Park. I guess digital requires a ton of power for all the processing 'computer' equipment, thats why its still analog. Its kinda hard to have an all solar site where it snows and this one as at 10,000 feet.

    It would be nice to see more of these as batterys and solar gets better.

    That's awesome how its way out there and they're getting cell coverage. Its still awesome that you have a cell site operating at that altitude. But with processors becoming so advanced, you knew it was bound to happen.

    That looks pretty cool. I wish other wireless carriers would consider this along the Gulf Coastal Region as a backup along with their current generators for an add'l backup during Hurricane season..

    Altho todays base-stations are more powerful, they have also gotten much more energy efficient. A new 3G base-station is something like 80% more energy efficient than a 10 year old analog one. And with special solutions (like Ericsson's "main-remote" used here) the energy use is optimized even further.

    Not sure about the mechanical engineering, but those solar panels would have to be bolted down real good to keep a hurricane wind from ripping them up, I guess :confused:

    Anyway, the idea of this site in Cambodia, is that it is fully self sustaining. Usually sites need to be located near an electric grid for power. And then need to have backhaul to the switch via fixed-line or be in range of another site for microwave transmission (like ~30 miles and Line of Sight). This one you can throw anywhere. Something not done too often (or ever!)
