LTE è soggetto a uno sviluppo continuo. La release 10 (LTE-Advanced) ha introdotto l'aggregazione delle portanti (CA) come miglioramento primario. Le release 11 e 12 aggiungono diversi nuovi componenti a LTE. Alcuni sono miglioramenti alle funzionalità esistenti (come miglioramenti a CA), mentre altri sono concetti completamente nuovi, come il multipunto coordinato (CoMP).Questa nota di applicazione riassume le soluzioni per test di Rohde & Schwarz per LTE-Advanced in base alle release 11 e 12 utilizzando generatori di segnali vettoriali, analizzatori di segnali e di spettro e tester di comunicazione radio in banda larga.
