Стандарт LTE непрерывно развивается. Основным усовершенствованием в версии 10 (LTE-Advanced) была технология объединения несущих (CA). В версиях 11 и 12 в стандарт LTE добавлено несколько новых компонентов. Улучшены некоторые имеющиеся функции (например, усовершенствована технология CA) и добавлены совершенно новые концепции, такие как координированная передача и прием (CoMP).В этом документе кратко описываются решения для испытаний от Rohde & Schwarz для сетей LTE-Advanced версий 11 и 12, в которых используются векторные генераторы сигналов, анализаторы сигналов и спектра и широкополосный радиокоммуникационный тестер.
