Radiowave propagation www.itu.int/itu-r/go/rsg3/ Scope Propagation of radio waves in ionized and non-ionized media and the characteristics of radio noise, for the purpose of improving radiocommunication systems. Structure The following four Working Parties (WPs) carry out studies on the Questions assigned to Study Group (SG) 3: WP 3J Propagation fundamentals WP 3K Point-to-area propagation WP 3L Ionospheric propagation and radio noise WP 3M Point-to-point and Earth-space propagation

With the growing interest in delivery of broadband services through local access networks, WP 3K studies the propagation effects associated with millimetric radio systems (e.g. operating around 20-50 GHz) used for point-to-multipoint distribution. Prediction of area coverage has to address the effects of buildings, their spatial distribution, attenuation and scattering from vegetation, and attenuation by rain. Methods to quantify the relevant propagation effects such as attenuation and distortion due to multipath are a key area of study in WP 3K.

Similarly, propagation impairments on slant paths from satellites are treated by a series of Recommendations that contain prediction procedures that quantify the relevant effects and, in turn, provide an assessment of overall propagation loss, fading behaviour or signal depolarization. Recommendations are available that apply to the fixed-satellite service (FSS), the mobile-satellite service (MSS) and the broadcasting-satellite service (BSS).
