The frequency bands 902-928, 2.45GHz and 5.8 GHz, when used with certain restrictions in two methods of spread spectrum modulation can have a theoretical maximum of 1W US. The 2.4 and 5.8 GHz bands generally overlap in Europe where the limit is half that and in Japan where the limit is generally 100 mw. In addition, there are more restrictions on antenna gain in Europe / Japan than in the US. Tom On Friday, March 06, 1998 4:13 PM, Ryan E.
