What is RSSI and how is it used in FPV systems?
RSSI, or Received Signal Strength Indication, is a critical metric in wireless communication systems. It measures the strength of the signal between a transmitter and a receiver, providing valuable information about the quality of the connection. In the context of FPV (First Person View) systems, RSSI is used to determine the health of the radio link between the quadcopter and the radio transmitter.
FPV systems have become increasingly popular in recent years, enabling users to experience a first-person view of their quadcopter’s flight. However, maintaining a reliable radio link is crucial for ensuring safe and stable operation. RSSI provides an indication of the signal strength, which can help users avoid loss of radio signal and prevent unexpected crashes. In this article, we will explore the role of RSSI in FPV and Long Range systems, its measurement techniques, and its impact on performance.
