- Rohde & Schwarz’s Chinese subsidiary and Zhuhai DingLi have won a contract to supply 5G scanners to the operator China Mobile in 2021.
- The compact R&S TSME6 scanner simultaneously measures a variety of wireless communication technologies in multiple frequency bands.
- This is the third consecutive tender in which Rohde & Schwarz has been awarded the supply of R&S TSME6 frequency scanners by China Mobile.
Since 2019, China is building the world’s largest commercial 5G network, with over 70 % of the 5G base stations worldwide. Large numbers of 5G base stations in the low and medium frequency bands of 700 MHz and 2.1 GHz are planned and the long-term coexistence of 4G and 5G base stations will make network environments more and more complex. Since 2G and 3G will gradually be phased out, frequency clearance is very important in China right now.
The R&S TSME6 scanner is distinguished by its coverage of all frequency bands and all mobile communication standards. It therefore meets the 5G test requirements of China Mobile for the deployment and optimization of its network infrastructure.
The R&S TSME6 is used by testing services of major operators and base station manufacturers around the world since the the early stages of 5G deployment. It ensures 5G network quality with frequency clearance testing, interference hunting, network performance testing and network optimization.
The R&S TSME6 drive test scanner supports parallel measurements of wireless technologies including 5G NR, TDD-LTE, FDD-LTE, NB-IoT, eMTC/LTE-M, WCDMA, EVDO, CDMA, GSM, while meeting operation needs for simultaneous measurements in 3GPP multistandard networks. The scanner also covers all 5G NR frequency bands for sub 6 GHz TDD and FDD, including the 700 MHz, 2.1 GHz and 3.5 GHz frequency bands. In combination with the R&S TSME30DC and R&S TSME44DC downconverters, it also supports the FR2 frequency band from 24 GHz to 44 GHz, fulfilling Chinese network operator requirements.
The R&S TSME6 can also detect multipath propagation, measuring power, delay and Doppler shift and other parameters.
