Representative scientific research achievements

（1）

Professor Li Jiandong led and completed the project of "large scale wireless LAN and cellular network heterogeneous self-organization technology"

A heterogeneous self-organizing resource management architecture is proposed, Invented the independent access, mobile network, heterogeneous network streaming transmission method of WLAN, solved the challenges brought by large-scale network, high mobility of users and large business capacity, overcame the problem of effective adaptation of network resources and business flow transmission demand, enhanced the leading force of international standards in related fields in China, and developed WLAN access equipment and mobile broadband hotspot equipment The joint resource management equipment of standby and heterogeneous networks has been applied to more than 470 operators in more than 130 countries around the world, and has achieved good social and economic benefits.

The project won the second prize of 2014 National Technological Invention Award.

"Network resource management and control technology for dense wireless communication system" project led by Professor Li Jiandong

It breaks through the network resource management and control technology of dense wireless communication system, puts forward the network resource management architecture, and invents the multi-dimensional network resource active cognitive allocation method, the high-density user access method of regional resource linkage, and the network interference transfer method of cross domain resource coordination, so as to realize the network orderly flow of dense wireless communication system resources and ensure the network capacity The volume of production continued to grow at a high level. The project has realized the network portable, mainly used in gymnasiums, railway stations and other areas, and has been applied in the Great Hall of the people, National Stadium, capital airport and other key areas. More than 100 operators around the world use the relevant technologies and products of the project, and its market share has ranked first in the world for three consecutive years.

The project won the second prize of 2017 National Technological Invention Award.
