Normally on radio higher frequency uses less energy (and reach less distance and is more directive)
Actually, higher frequencies get you less distance for the same power and whether it's more directional depends entirely on the antenna. At higher frequencies, it's easier to make directional antennas, because they're smaller than at lower frequencies. However, WiFi antennas are generally designed to be omni-directional, or something approaching it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
