For lower frequencies (below 10 GHz), the attenuation is reasonably predictable. For high frequencies in the millimeter wave range, the attenuation not only increases, but becomes more dependent upon peculiar absorbing characteristics of H2O, O2, and the like. Figure 1 shows the areas of peak absorption in the millimeter wave spectrum."</li></ul>
