Huawei may be blacklisted by the U.S. and under scrutiny by governments around the world, but there is no disputing their status as a leader in the telecommunications industry. If there was any doubt about that, Huawei has just put it to rest.

According to an announcement on the company’s site, Huawei has achieved a world record for single user 5G smartphone speed, achieving 2.92 Gbps, in conjunction with Türk Telekom. The test, conducted in Istanbul, Turkey, was performed on a Huawei Mate 20 X 5G smartphone.

“We combined two 5G carriers and established a new world record by reaching speeds of above 2.92 Gbps in our live 5G test network,” said Yusuf Kıraç, Türk Telekom’s CTO. “We are also the first operator to experiment with the 5G New Radio Carrier Aggregation Technology (C-Band NR Carrier Aggregation), which doubles the 5G link speed. Türk Telekom will continue to lead the development of all new generation technologies that our country needs in the future, as we do today.

“We have reached unprecedented speeds thanks to this technology, which provides many benefits for users and operators,” said Kıraç. “The high speed and large capacity targets promised by 5G technology have been achieved.”

While governments around the world debate about how to address concerns and allegations that Huawei passes sensitive information to the Chinese government, operators have warned that banning Huawei will lead to 5G rollouts taking years longer and costing billions more. This latest test adds veracity to those claims and will no doubt be a factor in any negotiations moving forward.
