For the trials, the tier-1 mobile network operator trusted the commercially available Rohde & Schwarz 5G NR network measurement solution. It comprises an R&S TSME6 or an R&S TSMA6 network scanner for data collection and the R&S ROMES4 drive test software suite for analysis and visualization. Equipped with an antenna, the 5G NR measurement solution fits into a backpack or shoulder bag for convenient and efficient drive and walk testing (see Figure 6 and Figure 7).
The described 5G NR network measurement solution can be expanded to a frequency range of up to 30 GHz (FR2) using the downconverter R&S TSME30DC. To avoid an impact of the body of the test engineer on the measurement results, Rohde & Schwarz offers a backpack that allows to mount the 5G NR mmwave receive antenna above the head level (see Figure 8).
