Mobile communication technology evolves from GSM, 3G, LTE, to 5G now. The complexity of gNodeB technology has reached to a certain high level to induce enough challenge for test projects. High throughput, more antennas and massive capacity brings very heavy test jobs in lab. A full life cycle of gNodeB development projects must include all the tasks like functional test, load and capacity test, automatic non-regression test and stability test. These test cases may apply 1 single UE, multiple UEs, or even hundreds and thousands real UEs.Naselit’s MUTA solution provides a total system package of SW and HW. By integrating of the controlling of real Ues and IP application test modules, MUTA enables NEM to test their products efficiently and then reduce the cost of human resource in test labs and be able to commercialize gNB much earlier.
