The tests were carried out using a test setup with the R&S CMW500 wideband radio communication tester and R&S CMX500 5G NR signalling tester from Rohde & Schwarz, and the MediaTek Helio M70 5G modem for the sub 6 GHz band.
The test setup provided a 5G network simulation with a signalling connection compliant with 3GPP Release 15.
5G NR will initially operate in non-standalone (NSA) mode, largely relying on existing 4G LTE infrastructure, and then migrate to standalone (SA) mode using 5G NR network infrastructure.
Commenting, JS Pan, General Manager of Wireless System Design and Partnership at MediaTek, "MediaTek’s Helio M70 is the industry's fastest sub 6 GHz modem and is expected to appear in next generation 5G devices by 2020. Helio M70 is the only 5G chipset with dual LTE and 5G connectivity and multimode capability that supports all current cellular generations from 2G to 5G. It presents an ideal solution to deliver a 5G experience with ultra-fast connectivity and intelligent power saving."
The R&S CMX500 5G NR signaling tester can be easily integrated into the existing Rohde & Schwarz LTE test setup. Together with the R&S CMW500 wideband communication tester, it is said to provide a versatile test solution during R&D. The R&S CMX500 supports both SA and NSA mode. Using this future-proof setup, developers of 5G user equipment and infrastructure should be able to quickly and reliably demonstrate and assure 5G NR compliance of their devices.
