China Broadcasting Network Corporation (CBN), Ericsson and its ecosystem partner, UNISOC have carried out an interoperability test based on the 3GPP standards contributed by CBN and terminal enhancements on 700 MHz band n28. The demo used Ericsson wireless equipment and downlink 4-stream technology to achieve an average cell downlink rate of more than 600 Mbps on UNISOC’s commercial customer premise equipment (CPE) with 4 receive antennas, setting a record for downlink data rate of commercial 5G systems in the sub-1-GHz frequency range.

The successful test means that CBN, who is the fourth largest communications service provider in China, is well positioned to rapidly deploy 5G and now has a solid technical foundation to expand the innovative applications of 5G into the low frequency bands.

The 700 MHz frequency band is part of the wider ultra-high frequency (UHF) band used previously for terrestrial broadcasting. It will improve connectivity in rural areas thanks to its ability to support better coverage in open spaces. Moreover, with its wide territorial reach and good penetration in buildings, the 700 MHz band will help service providers meet the rising consumer demand for audiovisual content and other broadband services over wireless networks.

Li Shuang, Deputy Director of Department of Technology Development, CBN, says: “CBN always extensively cooperates with domestic and international industry partners with innovation-driven, open and win-win concepts in mind, promoting continuous maturation of the global industry chain of 5G 700 MHz  and is committed to building a high-quality nationwide 5G network in China. The successful test by Ericsson based on the 3GPP 5G standards contributed by CBN, including the 700 MHz technology standard and n28 band terminal enhancements standard, has improved the 700 MHz network capability efficiently, which is of great significance to the innovation of low-band 5G networks in various scenarios.”


Peng Junjiang, General Manager of Northeast Asia R&D, Ericsson, says: “The 700 MHz network capability test based on CBN’s innovative technology standards validates the new capability of 5G low-band networks, while demonstrating Ericsson’s strong cooperation with chipset and device partners. It also demonstrates the high performance and adaptability of Ericsson’s low band 5G systems.  We have expanded the 700 MHz ecosystem from smartphones to a wider range of terminal form factors including CPE, leveraging efficient technology to provide more usage scenarios for the commercialization of the 700 MHz network in China and the world.”

Xia Xiaofei, Vice President of Market Management Department of UNISOC, says: “The successful interoperability test of the downlink 4 by 4 MIMO in the 700 MHz frequency band will support operators to deploy new 5G NR network more efficiently”

In a real-world environment, CBN can dynamically adjust the number of streams based on radio conditions to reach the optimal rate possible under wireless conditions. When widely supported by commercial CPE and other 700 MHz terminal devices in the future, the downlink 4-stream technology will cater for various innovative 5G applications as well as improve coverage in rural and suburban areas.

This Interoperability Development Testing (IoDT) was carried out at the Ericsson Beijing Lab using a 5G CPE with an embedded 5G chipset, UNISOC V 510, and Ericsson’ s 700 MHz 4T4R wireless network equipment.
