802.11a might do what you need. Not sure if it has been standardized yet, but if not there are a number of proprietary implementations in the same speed range. It promises 50Mbps with similar properties to 802.11b.
20 miles is going to be a long throw, but not outside the range of possibilities if you have line of site and good rooftop acesss. You will need some big antennas though. A site in the middle making it 2 10 meg shots would be ideal.
FCC Part 15.247 limits EIRP. You can't legally put out enough power in the unlicenced bands.
