Qualcomm Technologies has made the world’s first large-bandwidth 5G data call in the 700MHz (Band n28) FDD spectrum band in China.
The 700MHz band is just being opened up as the previous analogue TV services have shut down. The frequency gives longer range than the 2.4 or 3.8GHz bands and so is of significant interest for applications such as the Internet of Things and for rural areas. However there is a challenge to get high bandwidth.
This is why Qualcomm worked with China Broadcasting Network (CBN) on the demonstration. TV operator CBN was awarded a 5G license last year and the 700MHz band was approved by the 3GPP standards body in March 2020.
This used the 2x30MHz technical specifications of CBN’s 700MHz FDD band and a 5G smartphone form factor mobile test device powered by Qualcomm’s Snapdragon X55 5G Modem-RF System. This achieved download speeds of more than 300 Mbit/s.
Qualcomm is also working with Vivo, ZTE, Quectel, Fibocom and Gosuncn to launch the first batch of commercial 5G devices that support CBN’s 700 MHz including smartphones, CPE and 5G modules, all powered by the flagship Snapdragon 865 5G Mobile Platform and/or the Snapdragon X55 5G Modem-RF System.
CBN has also accelerated the establishment of 5G trial network pilot project for applications such as media convergence, IoT in agriculture, industrial interconnection, Ubiquitous Power Internet of Things (UPIOT) and others. The state-owned carrier is the sole network operator in China authorized by the government to operate nationwide cable TV network providing cable TV, mobile, fixed broadband, satellite communication services as well as providing public safety services.
“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,” said Durga Malladi, senior vice president and general manager, 4G/5G at Qualcomm Technologies.
“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,” said Qingjun Zeng, deputy general manager, China Broadcasting Network. “Over the past year, we have been actively advancing international standardization and nationwide construction of large-bandwidth 700MHz networks. Our collaborative effort with Qualcomm Technologies in achieving the world’s first large-bandwidth 700MHz Band 2×30 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.”
