Formula
Allowable path loss = transmit power + antenna gains − receiver sensitivity − margin; distance km = 10^[(path loss − 32.44 − 20 log10 MHz) ÷ 20]
What the result means
The main result is a deterministic estimate based on the entered assumptions. Supporting values make the margin, demand, or conversion visible so you can compare scenarios without treating the output as a guarantee.
Coverage radius is meaningful only for a wireless transfer path. For wired or internet data transfer, use measured route reach and service limits instead of this radio model.
