Rohde & Schwarz’s 5G Site Testing Solution (5G STS) combines all the functional, RF, and signaling tests required for 5G installation and troubleshooting in one integrated package. The 5G STS can run 5G and LTE tests simultaneously.
With the new test toolkit, field service engineers can accelerate the process of site acceptance and troubleshooting each new cell site for capabilities, such as beamforming and 5G/LTE dual connectivity, to verify the correct installation and performance and to ensure quality of service (QoS).
The integrated 5G test package is comprised of the R&S TSMA6 receiver plus the R&S TSME30DC downconverter, the handheld network troubleshooter QualiPoc Android, and the R&S Cable Rider ZPH analyzer.
The R&S TSMA6 autonomous receiver uses automatic channel detection (ACD) to show all LTE and 5G signals, identify channel frequency, and decode the PCI/SSB information for quality analysis of the signal. ACD automatically configures the receiver with the correct measurement settings, eliminating the need for the field service engineers to manually enter the settings into the instrument.
The QualiPoc Android smartphone is used to detect the presence of a 5G carrier and to verify the fundamental parameters of uplink speed, downlink speed, and latency. The handheld device can conduct cell and beam quality measurements and verify the presence and quality of the LTE anchor cell, which is essential in 5G non-standalone (NSA) mode, said Rohde & Schwarz.
The optional R&S Cable Rider ZPH, which combines a spectral analyzer, cable, and antenna tester functionality, can measure the occupied bandwidth of the 5G carrier. The zero-span feature enables the SSB to be viewed in the time domain and to determine the number of beams. The tester can also measure optical power and RF-conducted measurements of VSWR and distance-to-fault at the cell site.
