- China Mobile, China Telecom and China Unicom have selected the R&S TSME6 drive test scanner from Rohde & Schwarz for their 5G network deployment and optimization efforts.
In China, commercial use of 5G networks started in 2019. By today, it has developed into one of the largest 5G networks worldwide, operated by the three principle mobile carriers: China Mobile, China Telecom and China Unicom. The increasing number of 5G NR base stations have made China´s mobile networks more complex. In addition, the impact of 5G NR on existing 4G networks needs to be taken into consideration. Therefore, even after the initial deployment of 5G, optimization to improve network performance and efficiency becomes increasingly important.
The compact R&S TSME6 drive test scanner from Rohde & Schwarz is used for measuring coverage and interference. The scanner passively captures data from the air interface, offering an accurate view of the RF environment and all information messages of multiple technologies sent out by the networks without the need to subscribe to the network services.
The scanner supports parallel measurements of wireless technologies including 5G NR, TDD-LTE, FDD-LTE, NB-IoT, eMTC/LTE-M, WCDMA, EVDO, CDMA and GSM, meeting operator needs for simultaneous measurements on 3GPP multistandard networks. In addition, the scanner covers all 5G NR frequency bands for sub6 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 supports also the FR2 frequency band from 24 GHz to 44 GHz, fulfilling the requirements of Chinese network operators.
The R&S TSME6 dynamic range can reach more than 30 dB, its sensitivity enables to detect signals as low as -143 dBm, and the 5G NR same-frequency multicell dynamic range is 24 dB. In addition, the R&S TSME6 detects multipath propagation, measuring power, delay and Doppler shift.
Rohde & Schwarz mobile network testing has been cooperating with Zhuhai DingLi Corp., Ltd. to address the Chinese market for more than 10 years. Based in Zhuhai, China, the mobile network test and measurement solution providers delivers the drive test software with a Chinese GUI to complement the test scanners from Rohde & Schwarz.
