11.10.10 How Do Engineers Predict Whether A Radio Link Will Work?

Before installing a radio system, engineers must estimate whether sufficient signal strength will reach the receiver. This FAQ explains radio path analysis, path loss, diffraction, clutter, atmospheric losses, fade margin, and the practical techniques used to determine whether a proposed communication link will operate reliably.
