微小基站的传输接入规划及建设方案探讨

摘要

相比于宏基站,LTE微小基站由于具有部署简单、组网灵活、维护方便以及功耗低等突出优势,在未来将得到广泛应用。与此同时,微小基站还具有高密度及大规模部署的特点,如采用传统的基站传输接入建设方案,将会对接入光缆、网络容量、设备端口等带来重大压力。通过分析微小基站的传输接入需求,针对性地提出了三种微小基站的传输接入规划及建设方案,并在网络部署成本和承载品质等方面分别对各方案的优劣势进行了对比分析和探讨。%Compared to the macro-cell, LTE small cell enjoys certain outstanding advantages, such as sim-ple deployment, flexible networking, easy maintenance and low power consumption, and thus would be widely used in the future. In addition, the small cell also features high-density and large-scale deploy-ment. With the adoption of traditional transmission access scheme, the small cells would bring great chal-lenges to the optical fiber cable, network capacity and equipment port. Based on analysis of the transmis-sion access requirements for small cell,three planning and construction schemes of transmission access net-work for small cells are proposed. In addition, the advantages and disadvantages of each scheme are ana-lyzed and discussed in terms of the cost and capacity of network deployment.
