摘　　要：基于新型三层架构分布式基站(Lamp Site)的产品性能和组网设计,根据Lamp Site在几种典型室分场景中的布设应用以及设备性能的外场测试情况,采集分析了不同场景下的测试数据,重点研究了信号覆盖数据以及应用设计院AIDP室分规划仿真软件进行覆盖预测。总结出Lamp Site同频组网时下载速率可达70Mbps,但要支持更多载波数时,存在升级pRRU风险;在酒店等穿透场景下当pRRU布设在走廊且CRS功率为-8.1d Bm时,房间内信号相对偏弱,室内覆盖效果尚需优化。Based on the product performance and the networking design of the new three-layer architecture distributed base station （LampSite）, the layout application in several typical indoor distribution scenes and the field test results of the device’s performance on LampSite, the test data in different scenes were acquired and analyzed. The main focus was put on signal coverage data and the application planning simulation software to predict coverage. Several conclusions are drawn. LampSite download rate reaches to 70Mbps in the condition of co-frequency networking, but there is upgrading pRRU risk in the case of much larger amounts of supported carriers. In the permeable scenes, such as hotel, the signal in room is relatively weak when pRRU is deployed in the corridor and the CRS power is-8.1dBm, and the indoor coverage effect can be further optimized.
