WebMay 10, 2012 · One rule of thumb often used for Faraday cages to prevent transmission is that the holes need to be no larger than 1/10 of the wavelength of the signal. So for a 3G cell phone that operates at a frequency of 2.1 GHz (2.1 * 109 Hz), the wavelength = (3 * 108 m/sec) / (2.1 * 109 Hz) = .14 meters. Thus, for a Faraday cage to prevent this noise ... WebThe wavelength calculator solves for wavelength, velocity or frequency given 2 known variables. Choose a calculation to use the wavelength equation λ = v/f to solve for …
Webrelated to the wavelength. The parameters mentioned above are embedded into the far field equation. D is the largest physical dimension of the antenna. Wavelength is λ, which is related to the frequency of operation on the antenna. For smaller antennas the far field range length, r, can be approximated by:4
