Web30 de nov. de 2014 · This is called the free space path loss, and we can calculate this loss, in decibels, as: 20 log 10 ( d) + 20 log 10 ( f) + 32.45. Where: d is the distance, in kilometers. f is the frequency, in megahertz. So for your specified distance of 30 km, and a frequency of 868 MHz: 20 log 10 ( 30) + 20 log 10 ( 868) + 32.45 = 120.76 d B.
