5G NR network rollout is now – let’s test!: Page 6 of 10

3GPP release 15 specifies the initial 5G standardization framework of the radio access network called 5G New Radio (5G NR). The standard contains a high degree of flexibility in radio parameters, which complicates network measurements. However, Rohde & Schwarz has already conducted measurements in pre-commercial 5G NR trial networks with its commercially available 5G NR network measurement solution. We gained interesting insights into the new technology’s performance, capabilities and frequency bands.

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).
