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.
Abstract
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 explores and proposes an efficient and economical 4G/5G deep cover-age indoor distribution system solution suitable for underground parking garages,small super-markets,and other flat level scenarios.The proposed system consists of digital near end access u-nits,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 effec-tively 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 significant-ly 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.
