A tool employed in radio frequency engineering determines the power received by one antenna based on the transmitted power, antenna gains, and distance between them. For instance, it can predict signal strength at a receiver given the transmitter’s output and the characteristics of both antennas. This predictive capability is invaluable for system design and performance evaluation.
Predicting signal strength is fundamental for designing reliable wireless communication systems. Accurate power transfer calculations are essential for optimizing range, ensuring sufficient signal-to-noise ratio, and managing interference. Harald T. Friis’s original work on this topic, dating back to the 1940s, laid the foundation for modern link budget analysis, a critical process for optimizing communication links. This foundational concept remains crucial in diverse applications from satellite communication to WiFi network design.
