She may be thinking of Clearwire (or may want to consider it) - it's transmitted via radio, somehow? You don't need to wire anything for that one, the modem just picks up a signal. I had that when I lived in VA and it might've been $35 a month. Not the fastest, but pretty adequate, since I wasn't a gamer and didn't need to move files with any sort of speed.

They don't have coverage here, or didn't when I moved, so I have Comcast cable internet. No TV, no land line, and I don't live in a neighborhood that's wired for the spiffy high-tech internet that they'll let you buy from a phone company without a land line. Comcast isn't the best and I think I pay around $50 for just basic internet. Big to that.
