Devices meeting the 5G NR specs should support frequency ranges up to 52.6 GHz. However, the first 5G designs will use frequencies below 6 GHz with a focus on 3.5 GHz. For these sub-6 GHz carrier frequencies, 3GPP is currently talking about maximum bandwidths of 100 MHz per component carrier. The R&S CMW100 Communications Manufacturing Test Set with a measurement bandwidth of 160 MHz already enables testing of the first 5G NR Sub-6 GHz devices. With its high measuring speed, the R&S CMW100 is specially designed for mass production in production.

In addition to 5G NR Sub-6 GHz, the flexible test solution supports all relevant technologies such as LTE, WLAN and Bluetooth. This makes the R&S CMW100 a cost-optimized solution for mass production of all cellular and non-cellular (wireless connectivity) devices whose calibration and verification is performed in so-called non-signaling mode (analyzer/generator). End device manufacturers therefore have a wide range of measurement functions at their disposal – with only one investment in a single measurement device platform, one-time training and adaptation costs.

Anton Messmer, head of the mobile communications measurement department at Rohde & Schwarz, explains: “With the introduction of 5G, broader frequency ranges are being used. The use of bands below 6 GHz is the decisive factor for the construction of networks with reliable coverage. The R&S CMW100 shows that Rohde & Schwarz is equipped for 5G NR Sub-6 GHz”.

The latest 160 MHz version of the R&S CMW100 is now available from Rohde & Schwarz. Software options compatible with 5G NR Sub-6 GHz for vector signal analysis and generation will be available in 2018.
