# cranerainpl

## Syntax

## Description

returns the signal attenuation, `L`

= cranerainpl(`range`

,`freq`

,`rainrate`

)`L`

, due to rain based on the
Crane rain model. Signal attenuation is a function of the signal path length,
`range`

, the signal frequency, `freq`

, and
the rain rate, `rainrate`

. The rain rate is defined as the
long-term statistical rain rate. The attenuation model applies only for frequencies
from 1 GHz to 1000 GHz and is valid for ranges up to 22.5 km. The Crane model
accounts for the cellular nature of rainstorms. For more information about the Crane
rain model, see [1].
