CBN, Ericsson and UNISOC show 700 MHz capability for 5G
A record-setting, MIMO downlink speed test has shown the enhanced network capability of the 700 MHz frequency band for 5G.

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.”
