The call was carried out along with Chinese state-owned firm China Broadcasting Network and was in compliance with the 2x30MHz technical specifications of CBN’s 700MHz FDD band.

The trial used a 5G smartphone form factor mobile test device powered by the Qualcomm Snapdragon X55 5G Modem-RF System.

Qualcomm said in a statement that speeds of more than 300Mbps were achieved and this "provides a foundation for further enhancing the spectral efficiency of the 700MHz band and accelerating CBN’s commercial 5G rollouts nationwide".

“Qualcomm Technologies is excited to work with CBN and the industry to continue to advance key technologies that are instrumental for 5G commercialisation worldwide,” said Durga Malladi, senior vice-president and general manager, 4G/5G, Qualcomm Technologies.

“It is of great significance to achieve the wideband FDD 2x30MHz 5G data call in the 700MHz band with CBN. We are also proud to see the first wave of commercial 5G mobile devices supporting 700MHz powered by our Snapdragon 5G Modem-RF systems and are set to provide strong support for CBN’s deployment of 5G devices and services.”

Qingjun Zeng, deputy general manager, China Broadcasting Network, said: “With the goal of creating a business model combining media convergence and 5G, CBN has been sharping our competitive edge based on continuous innovations in 5G technology, content platform and business model.

“Over the past year, we have been actively advancing international standardisation and nationwide construction of large-bandwidth 700MHz networks. Our collaborative effort with Qualcomm Technologies in achieving the world’s first large-bandwidth 700MHz Band 2x30 MHz 5G call marks a great step towards our construction of high-quality 5G networks over the 700MHz band.

"We look forward to joining forces with industry partners to accelerate the nationwide coverage of CBN’s 5G networks which can support the high-quality development of ICT industry and radio & television industry as well as help boost the country’s economy.”
