This page is oriented to the system engineer planning a radio application with EtherNudge.
For this we included:
We hope you find this area of the website usefull and look forward to any feedback that can improve and enrich it!
The Egli model is positioned for rural terrain, with hills up to 15 m hight and based on a study done in the USA.
Pathloss = 117 + 40* log(distance) + 20*log(frequency)  20*log (HeightTx * HeightRx)
Pathloss is the attenuation in dB that is expected for a given distance, frequency and antenna heights.
Fill in the values to calculate the propagation loss or else enter an acceptable propagation loss to calculate the maximum transmission distance.
A  Attenuation (dB) 


D  Transmission distance 


Ht  Antenna height 


F  Frequency 


Hr  Antenna height 

This page converts between two common units for radio power  Watts (W) and Decibel "milliwatts" (dBm) dBm= 10*log10(W/ 0.001)
dBm  Decibels 

W  Watts
