Paul,

Look at what people are doing with Wi-Fi routers; if I'm not mistaken, those don't put out much more power and people can get ranges of up to 10 miles out of them with directional antennas.

Just curious, but how could such low-power transceivers be of any practical use for packet? Wouldn't the RF footprint be so limited that hardly anyone in the neighborhood would be able to use it? Am I missing something here... or is the plan to use an amplifier for wider coverage?
