Such as Pre5G.
As early as 2065438+June 2004, ZTE's chief scientist took the lead in proposing the concept of Pre5G in the industry at the 5GWorldSummit held in the Netherlands.
The core idea of Pre5G is to deploy 5G technology in advance, which greatly improves the performance of 4G networks, and users can get an experience close to 5G by using 4G terminals.
On the one hand, the throughput of LTE network is increased by 10 times, the number of connections is increased by 100 times, and the delay is shortened by 80%, which effectively solves three major problems that operators must face directly before the large-scale commercialization of 5G: the contradiction between limited spectrum resources and the rapid development of MBB and the Internet of Things, capacity improvement and cell interference in crowded scenes, and network congestion caused by massive access to the Internet of Things.
On the other hand, it also takes into account the network investment of operators. After the deployment of 5G, related equipment and technologies can continue to be extended through smooth upgrade.
This concept shocked the industry.
Nowadays, although the transition schemes from 4G to 5G vary from manufacturer to manufacturer, the key technologies of Pre5G, such as MassiveMIMO, MUSA and UDN, are all important components in each scheme.
In June of the same year165438+1October, ZTE completed the world's first pre-commercial field test of Pre5G base station based on MassiveMIMO technology.
20 15 In March, at MWC (World Mobile Communications Conference) 20 15, ZTE officially released the Pre5G base station with baseband RF integration, and won the GTI Innovation and Solution Award and the GTB Wireless Basic Innovation Scheme Award.
At the end of the year, ZTE realized the small-scale commercialization of Pre5G.
On March 20 16, ZTE put forward the Pre5GMassiveMIMO solution at MWC20 16, which shocked the audience again and won two global mobile awards: "Best Mobile Technology Breakthrough Award" and CTO Choice Award (superior to all mobile technologies-CTO Choice 20 16).
On September 8, 20 16, Softbank of Japan officially launched the "5GP Plan" and became the first commercial operator of Pre5G Massive MIMO in the world. As a strategic partner of Softbank, ZTE is also an important promoter of this plan.
From 2065438 to February 2007, relying on a large number of measured data of TDD Massive MIMO, ZTE overcame technical barriers and successfully launched Massive MIMO products based on FDD system, which opened the door for the evolution of the world's most extensive FDDLTE network to 5G, and successfully applied for hundreds of related patents, locking in the technical advantages in this field.
So far, ZTE Pre5G has been deployed in more than 40 networks in 30 countries.
In fact, Pre5G is just the tip of the iceberg of ZTE's 5G layout.
During MWC20 17 at the end of February this year, ZTE took the lead in releasing a full range of high and low frequency 5G base stations.
According to the latest data, by the end of 20 16, ZTE had accumulated more than 500 5G patent applications.
Since 20 16, with the approach of commercial nodes, 5G has gradually warmed up, and various manufacturers have begun to prepare to pick fruits, and their efforts on 5G have become more and more intense.
