3D-MIMO技术在校园场景中的应用研究

Application of 3D-MIMO Technology in Campus Scene

移动业务爆发时代已来临,用户容量扩充和用户感知提升矛盾日渐突出。尤其高校场景频谱资源不足问题突出,重点场景已部署800M+1.8G+2.1G三层网配置。但是,通过分裂小区并实施扩容后,仍难满足用户高质量需求,需要新技术、新方案提高频率资源利用率,提升用户感知。因此,创新地采用3D-MIMO 2.6G基站替换原有TDD宏站,在XX大学学生食堂、宿舍楼高热区域进行部署及能力验证。测试结果表明,3D-MIMO解决方案可有效解决频率受限情况下的容量提升问题,有效释放网络压抑流量,突破了用户体验瓶颈,大幅提升了4G的网络能力。

The era of mobile service outbreak has come,and the contradiction between the expansion of user capacity and the enhancement of user perception has become increasingly prominent.In particular,the problem of insufficient spectrum resources in University scenarios is prominent.800M+1.8G+2.1G three-layer network configuration has been deployed in key scenarios.However,it is still difficult to meet the high-quality needs of users by dividing the cell and implementing expansion.New technologies and schemes are needed to improve the utilization rate of frequency resources and enhance user perception.Therefore,the original TDD macro station is innovatively replaced by 3D-MIMO 2.6G base station to deploy and verify its capability in the hot area of XX University student canteen and dormitory building.The test results show that the 3D-MIMO solution can effectively solve the problem of capacity improvement under frequency constraints,effectively release network traffic suppression,break through the user experience bottleneck,and greatly enhance the network capacity of 4G.
