It is evident from Equation (1) that, all other variables held constant, as the transmission frequency is reduced, the wavelength, λ, increases.

Λ - The wavelength of the carrier (i.e., the center frequency of the radiated signal)ĭ - The distance between the transmitting and receiving antennas. G t - The gain of the transmitting antenna. Where the (λ/4πd) 2 term is sometimes referred to as the path loss or free space loss. This article is available in PDF format for easy printing
