IoT-NTN Platform
NE6000 Test Solution
The ALifecom NE6000 Network Emulator has been upgraded with the latest 3GPP release 17 standard to support IoT over NTN. This platform combines a channel emulator, eNodeB, and EPC in a comprehensive test solution. This solution accurately replicates real-world signal propagation conditions for advanced testing and validation of IoT-NTN devices.
