Detailed Description

a log distance propagation model.

This model calculates the reception power with a so-called log-distance propagation model:

where:

• : the path loss distance exponent
• : reference distance (m)
• : path loss at reference distance (dB)
• : distance (m)
• : path loss (dB)

When the path loss is requested at a distance smaller than the reference distance, the tx power is returned.
