Working Party 3L

ITU‑R WP3L is a part of ITU Study Group 3 which concerns itself with radiowave propagation. WP3L is more specifically concerned with ionospheric propagation and radio noise.

A significant reference document maintained by WP3L is the ITU‑R Recommendation P.372 “Radio Noise” which is a significant reference document when planning radio services and considering the impact of sources of interference.

IARU is involved in discussions about the updating of P.372, drawing heavily on work done is some of its societies to measure current noise levels to professional standards.
