distance for a given path loss value. Use the Distance and Power change prediction calculator to predict how a proposed transmitter power change, whether an increase or a decrease, will affect your usable range -- OR -- how a proposed range requirement change, whether an increase or a decrease, will affect your transmitter power requirements, while factoring in the signal decay rate observed in your current system. All path loss & distance / power
