Short-Range Wireless Networks, kurz SRWN (dt. "Drahlose Netzwerke für den Nahbereich), ist der Oberbegriff verschiedener Funktechnologien mit einer physikalisch stark begrenzten Reichweite von wenigen Metern oder gar nur Zentimetern. Zu den SRWN-Funktechnologien zählen zum Beispiel:
Die Reichweitenbegrenzung wird hauptsächlich durch eine reduzierte Sendeleistung erreicht. Die stärkere Freiraumdämpfung bei hohen Übertragungsfrequenzen trägt ihren Beitrag zur Minimierung der Reichweite bei.
