There is greater attenuation due to rain when the signal frequency is high.so downlink is also kept at lower frequency. Air molecules, such as N2, O2, CO2 are roughly 3 to 4 ngstroms in diameter. What is the difference between uplink and downlink? Based on the relation between frequency and wavelengths, the higher the frequency, the shorter the wavelengths and therefore the distance of travel is lower. Bass sounds have wavelength about the size of the objects and waveguides in their path, whereas higher sounds are progressively deeper into the ray optics regime. The short answer is yes. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Sound waves travel slower in cold air than warm air because the molecules hit faster and transmit the pulse in less time in warm air. The energy of sound may dissipate along distance by many cause at the same rate in any frequency, Low frequency wave not carry in "longer distance" than high frequency.
