Estimation of rain attenuation on earth-space millimeter wave communications links
… calculating rain attenuation along earth-space millimeter wave communications links is proposed. The model computes attenuation as a function of point rainfall intensity for a given frequency, path elevation angle, and earth station latitude and altitude. Estimates of the attenuation …

Millimeter wave communications : from point-to-point links to agile network connections
Millimeter wave (mmWave) technologies promise to revolutionize wireless networks by enabling multi-gigabit data rates. However, they suffer from high attenuation, and hence have to use highly directional antennas to focus their power on the receiver. Existing radios have to scan the space to find …
