Comparison of mobile radio transmission at UHF and X band

Experimental measurements of mobile radio transmission have been made in a suburban area at 0.836 GHz and 11.2 GHz. The results are presented in terms of average transmission loss, level crossing rates, power spectra, average duration of fades, and probability distributions. Fading rates were predictably higher at 11.2 GHz but the average excess path loss over the free space calculation was comparable to the values obtained at UHF, lending encouragement to possible exploitation of the higher microwave bands for mobile radio.
