Lab Tests at Fraunhofer IIS

Scenario Description

The first scenario tested in the scope 6G-SKY Emulations is a combined terrestrial and non-terrestrial network. Here, a plane acting as a so-called high-altitude-platform (HAP) is providing a 5G non-terrestrial network (NTN) for User Equipment (UE) within an area on the ground. The connection to the 5G core network is provided by a backhaul connection via satellite. Besides the NTN, there is also a terrestrial network (TN) provided by base-stations (gNBs) on ground. The UE is served either by the terrestrial or the non-terrestrial network, depending on the connection conditions. This scenario is shown in Figure 1-1.

Overall result: the hybrid TN / NTN tests showed good and consistent performance.
