Working Party 3M (WP 3M) - Point-to-point and Earth-space propagation

​​​​​Working Party 3M (WP 3M) - Point-to-point and Earth-space propagation

WP 3M addresses radiowave propagation over point-to-point terrestrial paths and Earth-space paths, both for wanted and unwanted signals. For terrestrial paths, prediction methods are developed for both line-of-sight and over-the-horizon links, taking into account the possible mechanisms that can give rise to fading and distortion of the wanted signal. The resulting predictions, generally expressed in terms of a statistical distribution of propagation loss or outage, provide vital information for terrestrial link planning in the fixed service (FS).
