900 mhz and 1800 mhz. And facing East or West. And Satellite, somewhat
above 2.0 ghz. 

And a significant number of ISPs are currently employing 802.11 2.4 and
5.0+ ghz equipment for last mile links (Proxim Tsunami) and Motorola
Canopy gear.

There are also warnings regarding parts of the power grid.

However, fair warning. Perhaps Sean Donelan knows more?
