                      Millimeter Wave Terminal Performance

                      Millimeter_wave_terminal_performance_test_system.png

                      For 5Gmm-wave application scenarios, 3GPP TR38827 defines five-channel models for UMi (Urban Micro) CDL A~E of urban micro-base station and InO (Indoor Office) CDL A~E of indoor micro-base station. The purpose is to build a reconfigurable channel environment in the laboratory and verify the scene performance of base stations and terminals.


                      In order to achieve the above application scenario test in the laboratory, this test system has a perfect experimental environment such as a millimeter-wave full-band anechoic chamber, three-dimensional reconfigurable probe wall, millimeter-wave antenna, millimeter-wave frequency converter, and high-precision turntable. By accessing 5G core network and base station devices (or using base station emulator), using advanced instruments such as high-end channel simulator, it fully supports 5Gmm-wave mainstream band, supports all millimeter-wave channel fading models of 3GPP, and supports communication performance test of 5G base station, terminal, chip, and other morphological devices.


                      Using compact field technology, the system works with a base station emulator, spectrum analyzer, signal source, and terminal device to complete radiofrequency consistency test items defined by 3GPP 38521-2.

                      The millimeter-wave probe antenna of this system complies with the distance and angle layout requirements of 3GPP TR38827 by verifying the following channel model parameters in the test area:


                      Power Delay Profile (PDP)


                      Doppler/Temporal correlation


                      PAS similarity percentage (PSP)


                      Cross-polarization


                      Power validation


                      Finally, the similarity of laboratory channel environment is verified according to the channel verification criteria of 3GPP.
