The Shenzhen-based telecom equipment manufacturer ZTE Corporation was granted a certificate for a 5G network interoperability test by China’s Ministry of Industry and Information during a summit in Beijing on Wednesday.

On July 17, at the summit organised by the IMT-2020(5G) Promotion Group – an organization affiliated with the country’s top industry regulator to boost the development of the superfast technology – ZTE Corporation obtained permission to work on the China 5G Technology R&D (Research and Development) trials to pave the way for 5G commercial deployment, the Paper reported.

The interoperability testing trial this time centers on laboratory and field testing in SA (Stand Alone) and NSA (Non-Stand Alone) scenarios in the 2.6GHz and 3.5GHz spectrums respectively, as well as the performance of terminal base-band chips in terms of link level modulation and coding, network coding and link adaptation.

On July 11, ZTE announced it had been the industry’s first to complete the 5G base station RF OTA (over the air) test at 26GHz in the millimeter-wave frequency band in China’s enhanced 5G technology R&D trial, which was organized by the IMT-2020(5G) Promotion Group as well.

Prior to the completion, the company had been in the third phase of the China 5G Technology R&D trial, with successful completions on laboratory and field testing in SA (Stand Alone) and NSA (Non-Stand Alone) scenarios at 2.6GHz, 3.5GHz and 4.9GHz frequency bands.

With the 3.5GHz band, ZTE achieved a peak data rate of 1.4Gbps in the trial, which was close to the theoretical limit.

According to public information on the first batch of 5G commercial deployments in the world, ZTE has secured 25 5G commercial contracts worldwide, covering major 5G markets such as China, Europe, the Asia Pacific and Middle East, cooperating with more than 60 companies worldwide.
