NGMN Alliance has defined a testing framework for the NGMN 5G pre-commercial networks trials. The framework is designed to evaluate the performance of 5G networks and ensure their readiness for commercial deployment. The framework includes testing of key 5G technologies such as Massive MIMO, beamforming, and network slicing. The framework also includes testing of 5G applications such as virtual reality, autonomous driving, and the Internet of Things. The framework is expected to be used by network operators, device manufacturers, and other stakeholders to evaluate the performance of 5G networks and ensure their readiness for commercial deployment.
