La norme LTE est continuellement en développement. Ainsi, l'agrégation de porteuses (CA, Carrier Agregation) constituait la principale amélioration qu'apportait la version 10 (LTE-Advanced). Les versions 11 et 12 apportent, elles aussi, plusieurs nouvelles composantes à cette norme. Certaines consistent en des améliorations de caractéristiques existantes (notamment de la CA), tandis que d'autres sont des concepts totalement nouveaux, tels que la technologie de coordination multipoint, ou CoMP (Co-ordinated Multi-Point).Cette note d'application récapitule les solutions de test de Rohde & Schwarz destinées aux versions 11 et 12 de la norme LTE-Advanced et faisant appel à des générateurs de signaux vectoriels, à des analyseurs de signaux et de spectre, ainsi qu'à un testeur de communications radio en large bande.
