支持5G共建共享和多系统共存的地铁隧道覆盖方案

5G Network Co-construction and Multi-system Co-existence Technical Solotions for Metro Tunnel Coverage

地铁是通信系统覆盖的重要口碑场景,为了实现多系统干扰共存并支持5G共建共享,重庆轨道交通环线二期采用了全新的5/4’’泄漏电缆,在覆盖技术方案上综合了多系统的覆盖需求,并在系统频率组合、功率控制、干扰控制上解决了多系统的干扰共存问题。网络实际运行和测试结果显示,各通信系统覆盖正常、干扰达标,5G共建共享功能和速率正常;证明该方案能在满足多系统接入的同时支持5G共建共享,并在覆盖指标和干扰控制上具有较好的效果。

Metro is an important scene in Network Service.In order to support the co-construction and sharing of 5G networks,the Line loop 2 of Chongqing Metro uses a new 5/4''leaky coaxial cable,integrates the coverage requirements of multi communication systems,and uses frequency combination,power and interference control solutions to solve the coexistence of multi systems.Network actual operation and test results show that the 5G co-construction and sharing function is stable and the download rate is standard,which proves that the solutions can meet the multi system access and support 5G co-construction and sharing,it has a good effect on network coverage and interference control.
