Chinese telecommunications giant Huawei has carried out the world’s first field test of fifth-generation cellular network (5G) technology using a 3.5 GHz band, which is expected to become the global 5G standard. Huawei also tested the connection between instrument and chip manufacturers, Thepaper.cn reported.
Huawei’s announcement comes after Qualcomm, an American competitor, successfully tested its 5G connection on Feb. 21. The latter’s connection is based on New Radio (NR) work in the 3rd Generation Partnership Project (3GPP), an international mobile telecommunications standards organization.
According to 3GPP’s official website, the standards for 5G technology will be set this year. Global telecom giants including Qualcomm, Huawei and Ericsson have all been carrying out research and tests of the new technology, competing for a leading role in setting those standards.
“The international community has reached a consensus that a unified 5G standard should be established. Currently, all the telecom giants have offered their technological patents to 3GPP, hoping that their standards will be the ones adopted,” an anonymous expert told Thepaper.cn, adding that the competition to set the 5G standards could affect national interests.
Chinese companies have gained ground in the 5G battle, where the U.S. and EU have long been leaders. During the No.87 RAN1 meeting held by 3GPP in 2016, the polar code, created by Chinese companies, was defined by participants from around the world as the control channel encoding scheme for the application of 5G in eMBB (enhanced mobile broadband) scenarios.
