摘　　要：对比3G网络,LTE网络的设备特性及传输需求有了很大的变化,分布式基站建设模式未来将成为LTE无线组网主流方案,但BBU集中方式与BBU分散方式各有不同的特点和适用场景。通过分析LTE无线设备特性对传输的影响,结合不同建设场景的不同需求,提出了三种典型的传输解决方案,并分析其各自的优缺点,同时明确了各种方案的适用场景。Compared with 3G networks, the device characteristics and the transmission needs of LTE network have changed. Distributed base station will become the main solution for LTE wireless network in the future. However, centralized BBU and decentralized BBU have their features to apply to various scenarios. By analyzing the impact of LTE wireless devices on transmission, combined with various needs of diverse construction scenes, three typical transmission schemes are proposed of which their advantages and disadvantages are analyzed, while the application scenarios tbr each scheme are specified.
