5G NR sub-6 GHz device testing platform

November 23, 2017 // By Jean-Pierre Joosting
Based on the CMW platform from Rohde & Schwarz, the latest version of the CMW100 communications manufacturing test set enables the testing and validation of sub-6 GHz 3GPP 5G new radio (NR) based devices.

3GPP's 5G NR will support frequency ranges up to 52.6 GHz, but initial 5G designs will use frequencies below 6 GHz with a focus on 3.5 GHz. For these sub-6 GHz carrier frequencies, 3GPP currently discusses a maximum bandwidth per component carrier of 100 MHz. Consequently, the CMW100 communications manufacturing test set with a measurement bandwidth of 160 MHz is ready for testing initial 5G NR sub-6 GHz wireless devices. Thanks to its high measurement speed, the CMW100 is an ideal for high-volume production environments.

The flexible testing system is suitable for all types of wireless devices, supporting LTE, WLAN and Bluetooth besides 5G NR sub-6 GHz. This makes the CMW100 cost-effective for mass production of cellular and non-cellular (wireless connectivity) devices calibrated and verified in so-called non-signaling mode (analyzer/generator). Manufacturers of handsets and devices profit from a variety of measurement functionalities with a single investment in equipment, training and adaptation costs.

Anton Messmer, Vice President Mobile Radio Testers at Rohde & Schwarz, said: “The evolution to 5G networks will employ a wider range of spectrum bands. Utilizing spectrum bands below 6 GHz is the decisive aspect of enabling deployments with reliable network coverage. The CMW100 demonstrates Rohde & Schwarz capability to support 5G NR sub-6 GHz and will help accelerate the 5G ecosystem.”

The latest 160 MHz version of CMW100 is available now. Dedicated vector signal analysis and generator software options supporting 5G NR sub-6 GHz will be available in 2018.
