摘　　要：面对传统无源室分DAS系统投资大、运维成本高及不支持高频段等挑战,文章探讨提出了一种适用于地下停车场、小型商超等平层场景的高效、经济的4G/5G深度覆盖室分系统解决方案。该方案系统由数字型近端接入单元、扩展单元及远端覆盖单元组成,支持多运营商多频多模接入,并具备完善的网管功能和远程控制功能。通过试点验证,该系统在提升室内覆盖质量的同时,有效控制了建设和运维成本,特别适用于低业务量、高成本效益的场景。结果表明,该系统能够显著改善地下车库等区域的4G/5G信号覆盖,确保用户业务需求得到满足,并具备推广应用的潜力。Faced with the challenges of large investment,high operation and maintenance costs,and lack of support for high-frequency bands in traditional passive indoor distributed antenna system(DAS),this article cxplores and proposes an cfficicnt and conomical 4G/5G decp coverage indoor distribution system solution suitable for underground parking garages,small supermarkets,and other flat level scenarios.The proposed system consists of digital near end access units,expansion units,and remote coverage units,supporting multi operator,multi frequency,and multi-mode access with comprehensive network management and remote controlling functions.Through pilot verification,the system not only improves indoor coverage quality but also effectively controls construction and operation costs,making it particularly suitable for scenarios with low traffic volume and high cost-effectiveness.The results show that the system can significantly improve 4G/5G signal coverage in areas such as underground garages,ensuring that users'business needs are met and has the potential for promotion and application.
