Recently, Rohde & Schwarz (hereinafter referred to as “R&S Company”) and Zhuhai Century Dingli Co., Ltd. (hereinafter referred to as “Century Dingli”) jointly won the bid for China Mobile’s 5G multi-mode frequency scanner centralized procurement project, R&S TSME6 5G The multimode frequency sweeper stands out in this collection. Up to now, as the only foreign company, R&S has all won the bids for the centralized procurement projects of the three major operators, China Mobile, China Unicom and China Telecom. With industry-leading product features and performance, the R&S TSME6 frequency scanner will provide a reliable measurement tool for the deployment and optimization of field networks in China.

China has entered the first year of 5G commercial use in 2019, and has built the world’s largest 5G network, with more than 700,000 5G base stations built and 330,000 shared base stations being promoted. The increase in the number of 5G base stations and the need for co-construction and sharing have made China Mobile’s network more and more complex. The impact of 5G network on the existing 4G network also needs to be considered. The frequency scanner can detect and optimize the overall performance of the network. An important test instrument to ensure the quality of mobile network communication.

As the industry’s first 5G frequency scanner, R&S TSME6 has provided testing services for major operators and base station manufacturers around the world in the early stage of 5G deployment, ensuring the quality of 5G networks in terms of frequency clearing test, interference search, network performance test and network optimization. . A single R&S TSME6 frequency scanner can support 5G, TDD-LTE, FDD-LTE, NB-IoT, eMTC, WCDMA, EVDO, CDMA, GSM and other parallel tests, fully meeting operators’ synchronous measurement requirements for 3GPP multi-standard networks , which greatly improves the test efficiency. In terms of frequency, the R&S TSME6 can cover all 5G Sub6GHz TDD and FDD frequency bands including 700MHz, 2.1GHz, 3.5GHz, etc., and can be extended to support the FR2 frequency band from 24 to 44 GHz by cascading R&S TSME44DC and other frequency conversion modules, which can completely cover Frequency band testing requirements of Chinese operators.

As the industry’s smallest, lightest, and lowest power 5G multimode frequency sweeper, the R&S TSME6 has excellent test performance. Its beam detection depth can reach more than 30dB, the ultra-low noise figure enables it to detect signals as low as -143dBm, and the 5G NR same-frequency multi-cell detection depth is as high as 24dB. In addition, the R&S TSME6 is the only device on the market that can fully detect multipath. It can measure the power, delay, Doppler shift and other parameters of each path, which is unique in the field of high-speed rail testing and channel modeling.

R&S’ comprehensive mobile network test solutions support all cellular technologies from 2G to 5G, supporting the entire network lifecycle from laboratory validation, spectrum cleanup, interference search and base station installation to site acceptance, benchmarking, optimization, troubleshooting and monitoring tests. In the future, R&S will continue to strengthen cooperation with a number of telecom operators such as China Mobile, China Unicom, China Telecom and China Radio and Television to help optimize and improve the quality and performance of China Mobile’s network.
