LTE农村广覆盖不足问题分析及解决方案探讨

Problem analysis and Solution Research on insufficient rural wide coverage of LTE

从农村覆盖场景入手,结合现场测试和分析LTE覆盖力达不到GSM覆盖水平的原因,并讨论了业务需求量较少、建站条件差、投资成本大的农村场景,能否通过新技术新方法弥补网络制式本身带来的不足。在此基础上,进一步对农村广覆盖场景下通过降低系统带宽提升边缘覆盖方案进行了测试验证,并提出不同系统带宽混合组网情况下测量带宽问题的解决方法。

Starting from the rural coverage scenario,combined with the on-site test and analysis of the reasons why LTE coverage can not reach the GSM coverage level,this paper discusses and studies the rural scenario with less business demand,poor station construction conditions and high investment cost,and whether it can make up for the shortcomings brought by the network system itself through new technologies and methods.On this basis,it further tests and verifies the scheme of improving edge coverage by reducing system bandwidth in the rural wide coverage scenario,and puts forward the solution to the problem of measuring bandwidth in the case of mixed networking with different system bandwidth.
