【摘要】 随着基站选址难度的进一步加大,分布式基站应用逐步成熟,BBU集中和RRU拉远等基站建设方案使得无线接入网可以满足用户无所不在的移动宽带接入需求。从无线接入网发展趋势出发,介绍了分布式基站特点及组网方式等内容,分析了BBU集中建设模式和RRU拉远建设模式的主要驱动力和适用场景,并以两个案例对分布式基站建设案例进行分析总结,提出了分布式基站建设的相关建议,可为国内外电信运营商的无线接入网络建设提供参考。更多还原

【Abstract】 Along with the increasing difficulty in base-station location,distributed base-station application is gradually mature,such base-station construction schemes as BBU concentration and RRU pull far enable wireless access network to meet the user’s ubiquitous mobile broadband access requirements.Based on the trend of wireless access network,the characteristics of distributed base-station,and its networking are given,the construction modes of BBU concentration and RRU pull far away as main driver and application scenarios are analyzed,the distributed base-station construction cases are summarized,and the relevant recommendations for construction of distributed base-station are suggested,thus providing a reference for wireless access network construction both at home and adroad.更多还原
