Wireless communications through free space using optical carrier (Free Space Optics, FSO) technology ensure high data rates, low error rates and power consumption and inherent security. However, FSO channel availability can be limited by path attenuation due to atmospheric hydrometeors, especially fog but also snowflakes and raindrops. In this work a parametric model to simulate droplets scattering effects on FSO links is proposed. Extinction and scattering effects versus precipitation rate will be analyzed for snow and rain particles. Multiple scattering effects will be briefly discussed.

Abstract
Wireless communications through free space using optical carrier (Free Space Optics, FSO) technology ensure high data rates, low error rates and power consumption and inherent security. However, FSO channel availability can be limited by path attenuation due to atmospheric hydrometeors, especially fog but also snowflakes and raindrops. In this work a parametric model to simulate droplets scattering effects on FSO links is proposed. Extinction and scattering effects versus precipitation rate will be analyzed for snow and rain particles. Multiple scattering effects will be briefly discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
