Just calculate it.
Wavelength = c / f where c = speed of light ~= 3*10^8 m/s, f = frequency The default channel, 26, is somewhere in the high region of the 2.4 GHz ISM band, which would be around 2.485 GHz => 2.485*10^9 Hz. Wavelength(high end) = (3*10^8 m/s) / (2.485*10^9 1/s) = 0.1208 meters => 12.08 cm. The low end of the 2.4 GHz is 2.400 GHz. so the wavelength there is: Wavelength(low end) = (3*10^8 m/s) / (2.0*10^9 Hz) => 15 centimeters So the wavelength is between 12 to 15 centimeters, depending on which channel you're sitting on. 13 centimeters is a good answer. -David _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Nahr ...
