基于U2100+2T4R技术广覆盖的设计方案

摘要

利用发射和接收分集技术，对U2100+2T4R技术的广覆盖工作原理和应用场景进行分析，从技术特点和设备配置方面设计给出两种不同覆盖方案以提高上下行覆盖和网络容量。通过测试验证，效果明显，可得到覆盖指标RSCP、Ec/Io提高了约40%，及造价成本节约了25%的覆盖效果，最后总结了U2100+2T4R技术作为农村广覆盖的设计方案特点和优势。%Using transmit and receive diversity techniques and analysing U2100+2T4R wide coverage of the work principle and application scenarios, two different coverage schemes are designed by using the technical characteristics and equipment configuration to improve the uplink and downlink coverage and network capacity. Through the test validation, the effect after the improvement is clear. The coverage indicators RSCP, Ec/Io increased by about 40%, and cost savings of 25%. Finally, the characteristics and advantages of the U2100+2T4R technology as the design scheme of the rural area are summarized.
