ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, today unveiled and showcased its Pre5G Ultra Dense Network (UDN) solution marking a new stage of Pre5G technologies at Mobile World Congress in Barcelona.

ZTE’s Pre5G UDN solution is centred on user experience and based on existing network architecture by virtue of interference management and suppression, mobility enhancement, and other key technologies. The technology provides a solution to address increasing interference between base stations with overlapping cells in dense networks. The solution achieves system frequency multiplexing and substantially increases efficiency and network capacity. Tests show that the downstream rate is increased more than10 times in the overlap areas between cells where the technology has been implemented.

ZTE initiated the idea of Pre5G at the first 5G World Summit. Pre5G uses the most practical core 5G technologies to deliver a near 5G user experience and is compatible with commercial LTE user equipment, and will be used commercially before 2020. By using operators' existing sites and spectrum resources, Pre5G dramatically enhances the access rate of existing network users and the overall network capacity, and effectively eases the challenges of the data traffic surge before 5G standardization, which allows mobile operators to efficiently evolve to 5G.

Massive MIMO (multiple-input and multiple-output), UDN, and Multi-User Shared Access (MUSA) are core Pre5G technologies, which will respectively solve three major problems that customers will encounter in the next few years: contradictions between limited spectrum resources and the rapid development of mobile broadband (MBB) and the IoT; capacity increase and cell interference problems in densely-populated areas; and network congestion problems caused by a deluge of IoT data.

In November 2014, ZTE carried out a pre-commercial field test of the world's first Pre5G base station based on Massive MIMO. In early 2015, ZTE released the first Pre5G commercial base station. To date, ZTE has completed pre-commercial field tests with a number of global operators, including China Mobile..

Dr. Xiang Jiying, ZTE's chief scientist, said: "With great support from high-end operators, Pre5G will become commercially available in 2016. Meaning that the commercial use of 5G technologies and the 5G experience will come into play ahead of schedule."

ZTE is a leading player in the 5G field. In 2015, ZTE continued its research into key 5G technologies covering network architecture design, multi-antenna technologies, high-frequency communications, IoT integration, new services (such as D2D, M2X, and URC), and much more.
