SHENZHEN, China -- ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, has released details of a new 5G access network architecture based on dynamic mesh networking.

ZTE believes that 5G RAN (radio access network) technology should be a dynamic mesh network based on IP backhaul. In 5G networks there could be many types of base station including UDN (user densification network), massive MIMO (multiple-input multiple-output), traditional macro, and D2D. These various base stations will coordinate with each other horizontally more often than they do in 4G networks, and so will require a dynamic and adaptive wireless mesh network.

ZTE's approach to the improvement of 5G network architecture will make it possible for 5G networks to implement highly-effective SDMA (space-division multiple access), and ZTE hopes this approach will become the next telecoms industry hotspot for 5G technology research.

ZTE has viewed 5G as a strategic product since 2012, and has established teams to develop major 5G technologies and prototypes, including new services and applications. Since 2009, ZTE has researched SDA (software defined air-interface) technology, and in 2013 debuted its 5G SDA technology.

“ZTE’s 5G SDA solution allows self-adaptation of the air interfaces, so that in the same network, a network element can supporting a variety of services, and the SDA can allow multiple wireless access technologies for optimal adaptation, maximising air interfaces efficiency,” ZTE Xiang Jiying said, “At present, SDA technology is a key research area for 5G.”

For base station collaboration technology, ZTE has developed its Cloud Radio solution, and has tested and implemented it for commercial use in 4G networks, laying a solid foundation for partially-dynamic 5G mesh networks. As 5G involves a large number of parallel computations, ZTE has also developed vector processing chips for both 4G and 5G technologies which increase device processing capacities by 10 times.

Broadband speeds are ramping up across Europe as the continent, at its own pace, follows North America towards a gigabit society. But there are many steps to take on the road to gigabit broadband availability and a number of technology options that can meet the various requirements of Europe’s high-speed fixed broadband network operators. During this radio show we will look at some of the catalysts for broadband network investments and examine the menu of technology options on offer, including vectoring and G.fast for copper plant evolution and the various deployment possibilities for FTTH/B.
