Testing all cellular NTN technologies (NR-NTN, NB-NTN, and Direct-to-Cell) with the CMX500 one-box tester
The CMX500 is the versatile solution designed for testing various NTN technologies, including NR-NTN, NB-NTN, and Direct-To-Cell (D2C, DTC), all conveniently housed in a single unit. It contains multiband and multiorbit support, along with a dedicated NTN workspace that enables users to visualize the deployed network and its relevant parameters.
Rohde & Schwarz offers an XLAPI Python Test Case package for the CMX500, which includes a range of Starlink LTE-DTC test scenarios. These scenarios cover critical aspects such as LTE attach time and success rates in DTC mode, Event A3 handover, cell reselection between intra-frequency LTE DTC cells, and recovery after Radio Link Failure (RLF) on LTE DTC cells, among others.
