FCC Part 15.247 limits EIRP. You can't legally put out enough power in the unlicenced bands.
Sure you can, you get more power with more directional antennas. Here's a company that will sell you everything you need: http://wavewireless.com They can get 25 miles. Using a 36db Yagi you can build the same thing yourself, as many have done. You do have to back off the transmitter slightly to stay within FCC limits, but 20+ miles 802.11b is easily done within FCC limits. I cannot speak to 802.11a, as I know nothing about how it works, or the frequences and power involved. -- Leo Bicknell - bicknell@ufp.org Systems Engineer - Internetworking Engineer - CCIE 3440 Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org
