New 5G radio standard used to transmit on 100MHz bandwidth on 3.5GHz band

China Mobile has tested an end-to-end 5G connection, which it claims to be the first based on 3GPP’s new radio (NR) standard. 

The operator will be demonstrating the technology at its global partner conference next week.

Vice president Li Zhengmao said: “China Mobile is committed to promoting the unified global 5G standard with industry partners. The achievement of end-to-end 5G NR interoperable connection testing, compliant with the 3GPP 5G NR standard, is an important milestone of 5G standard to productisation and pre-commercialisation from standard.”

The operator worked with US chipmaker Qualcomm and Chinese equipment vendor ZTE on the project, which used the 3.5GHz band – widely identified as the main spectrum band for 5G services.

The demonstration achieved a bandwidth of 100MHz – potentially able to transmit a huge amount of data. Last month SoftBank in Japan, also working with ZTE, achieved a data transmission speed in a 5G trial of almost 1Gbps on a bandwidth of just 20MHz.

Cristiano Amon, executive vice president of Qualcomm Technologies, said: “Achieving the world’s first end-to-end 5G NR interoperable data connection is true testament to our 5G leadership, driving toward the timely launch of standard-compliant commercial networks.”

The demonstration took place at China Mobile’s 5G Joint Innovation Centre, a distributed cluster of laboratories where the world’s largest mobile operator is working on 5G projects.

At the operator, Li said: “China Mobile is committed to working with other industry leaders, including Qualcomm Technologies and ZTE to promote that the 5G products continue to mature and the 5G industry marches to success.”

Xu Huijun, CTO of ZTE, said: “ZTE is aiming to become one of the first suppliers of commercial 5G equipment and solutions. During the course of 5G technology verification and product-based development, ZTE is actively verifying a multitude of key technologies, solutions and network models together with industry partners.”
