Working Party 3J (WP 3J) - Propagation fundamentals
WP 3J provides information and develops models describing the fundamental principles and mechanisms of radio-wave propagation in non-ionized media. Such material is used as the basis of propagation prediction methods developed by the other Working Parties. Recognizing the natural variability of the propagation medium, WP 3J prepares texts describing the statistical laws relevant to propagation behaviour and the means of expressing the temporal and spatial variability of propagation data.
