Spring Valley, CA | i don't like this...
because it appears they haven't accounted for the kind of windage that will be occuring at 12 miles up... it's cold and windy up there and if one of these things goes off course, then that would be a problem for subscribers now wouldn't it... |

said by russotto  :12 miles is above the airspace used by commercial air traffic. In fact, I believe it's above controlled airspace entirely. However what isn't mention if there is an armada of these things floating around (not stationary) what is it going to to particularly (very marginal signal) DSS satelite reception. Possibly even more commercial large signal satellite when the drift past in inclement weather.
Given the size and only 12 mi up that is a pretty large obect still, again especially for DSS, which is extreme line of sight (very narrow sight beam) full signal needed, especially if not perfect weather.

Yes, but the key word is TETHERED. Which means a cable extending back to the ground, just like the "barrage baloons" in WW II. Which means a hazard to air navigation.
Actually, this is a rather goofy scheme, akin to BPL, considering the plethora of antenna towers all over. |

| The tests are tethered. I can't find anything that indicates the ultimate 12-mile high blimp would be tethered. Indeed, I did find references to propulsion and avionics, which would indicate that it would be designed to fly and navigate itself, not only at the end of a cable.

Oh, riiiigggghhhhtt. Hundreds of these things are going to stay up by themselves on auto pilot and maintain station for years at a time.
Besides which, I can just see the RF soup nightmare up there as they all try to use a set band of frequencies at the same time with the TX power required for a decent signal at 12 miles at 900 Mhz and above. Never mind the uplinks.
No wonder they have taken so long to even test this dufus scheme. Seems to be just a bit much when you consider that it would be MUCH easier to just rent tower space. More reliable too in the long run. Less potential for disaster. |

Belvedere Tiburon, CA | Agreed all around. I wasn't saying untethered flight was workable, just that it was what they seemed to be planning.
