在密集城区LTE网络规划中，通用的传播模型和传统的仿真手段难以对网络覆盖和干扰情况做出精准预测，造成站点开通后实测的覆盖效果达不到规划目标值，影响了LTE建设进度和网络覆盖效果。通过在规划仿真过程中采用ATOLL的CROSSWAVE射线跟踪传播模型代替通SPM传播模型，能较好的模拟单个站点周边传播环境，有效提升站址规划的准确性。%In dense urban LTE network planning, universal propagation model and traditional simulation methods is difficult to make accurate forecasts of network coverage and interference, causing effects observed after the site opened up covering less than planned target, affecting the construction of LTE schedule and network coverage. ATOLL by CROSSWAVE propagation model using simulation in the planning process instead of generic SPM propagation model, capable of simulating the propagation environment surrounding a single site, effectively improve the accuracy of station site planning.
