Die Received Signal Strength Indication (RSSI) stellt einen Indikator für die Empfangsfeldstärke kabelloser Kommunikationsanwendungen dar.
Dieser Indikator wird von Mobiltelefonen und anderen auf Funkkommunikation angewiesenen Systemen benötigt, um einen für die Kommunikation brauchbaren Kanal zu finden. Falls die Signalstärke, die für eine erfolgreiche Kommunikation benötigt wird, auf dem aktuell genutzten Kanal unterschritten wird, kann mit Hilfe des RSSI-Wertes gegebenenfalls auf einen besseren Kanal gewechselt werden.
Der RSSI-Wert ist ein Ein-Byte-Wert, geht also von 0 bis 255, je höher, umso besser die Signalstärke (nach IEEE 802.11-Standard). Ein RSSI von 1 ist der geringste empfangbare Wert.
