Cells in the sky
Brad Templeton has a killer idea: using commercial airplanes as broadband cells in the sky, or specifically, a mesh network at altitude. A sample of his thinking here:
Airliners fly so often these days, spaced often just 40 miles apart along the oceanic routes. It should be possible with modern technology to produce a mesh network that transmits data from plane to plane using line of sight. Two planes should in theory be able to get line of sight at 30,000 feet if they are up to 400 nautical miles apart. The planes could provide data and voice service for passengers at a reasonable price, and also could relay for ships at sea and even remote locations.
One can also use lower bands that can go further, since there is no spectrum competition over the the open ocean, but I suspect planes don’t spend too much time more than 400 miles from any other airliner (or 200 miles from any land station.) In the high bands many megabits of data bandwidth are available, and in theory spectrum allocation is not an issue when out of sight of land, so even hundreds of megabits would be possible. An airline could offer just this service, or at a higher price switch to satellite in the few dead zones — which again, it should be able to predict with some accuracy. Aiming should be easy, since the aircraft all transmit their GPS coordinates regularly on transponder frequencies and can also do so in the data network. In fact, you would be able to know where a new mesh partner will be approaching, and where to point, before you could ever detect it with an omnidirectional antenna. And people could be given enough bandwidth for real internet, including voice. (Though that still means they should perhaps go to a phone lounge to have long conversations.)
Much food for thought there.

Good idea! Cringley had a similar thought and did a little experiment on this awhile back.

I feel like a fog. My life's been really boring today. I haven't been up to much.
