摘　　要：业界首次提出通过SDR技术,在要部署3.8 MHz U900县的L1800基站反向升级至DCS1800,替代原G900网络,消除部署U900传统内缓冲区,扩大U900部署范围至县城周边,U900部署范围可提升20%以上,U900部署效益增加明显。同时深入剖析了部署U900面临的干扰、掉话、互操作、终端适配等问题,提出了有效的解决方案。最终实现快速、全面、安全部署一张广度覆盖和深度覆盖完美结合的、质量有保障的、打底的U900网络,并能快速升级至L900。In the industry,it first puts forward using the SDR technology with reversing L1800 to upgrade to DCS1800 to replace the original G900 network in country town,to solve 3.8 MHz U900 deploying internal buffer area. With eliminating U900 buffer,expanding the scope of the U900 deployment to the county surrounding,U900 deployment range upgrade 20%. U900 deployment benefit has tremendous upgrade. In addition,it puts forward the solutions on in-depth U900 deployment of interference,dropped calls,interoperability,terminal adapter. With all key problems solved,it can quickly build the U900 network which is the perfect combination of broad coverage and in- depth coverage,and has guaranteed quality. The network can quickly upgrade to L900.
