I’m interested in maximum wi-fi speed at distance of 12 Km. We have limit at summary power of antenna and card - 1 W. Please, recommend some dish antennas with needed dBi. Wifi cards r52h have ability to regulate power in them, how much power we have to set them to avoid exceeding of summary power of 1 W. Frequency from 5,4 to 5,7.
P.S.
In our country, state structures of regulation radio frequency, count summary power of cards and amplification of antenna.For example, at frequency 5,4 we have maximum summary power of 1 W. Is this right by european standards or not?
