Legacy Radio Propagation Data
A collection of datasets from propagation measurements taken between 1944 and 1995. More detailed descriptions are provided on the linked page.
Raw propagation measurement data from 1944-1969 measurements at 40 MHz to 10 GHz over distances from 10 to 1000 km in several countries.
Spot measurements taken in 1963 and 1964 at 30-3000 MHz in environments that emphasize irregular terrain.
Spot measurements taken in 1968 at 30-3000 MHz with antenna heights of 3 m or less.
Over 4,000 attenuation values for measurements between 53.9 and 66.3 GHz in 0.1 GHz frequency increments at eleven pressure steps (1-100 kPa) for three temperatures (7, 30, 52°C) in 1991
Sample data from radio channel impulse response measurements at 915 MHz acquired in 1995 in bursts of 64 or 128 equally spaced impulses using a stationary transmitter and mobile receiver
