Legacy DAS Retrofit

老建築舊網升級Legacy Building Network Upgrade

面向老旧写字楼、酒店、公寓、商场、医院和公共建筑,在尽量复用既有馈线、天线、弱电井和机房资源的基础上,完成 4G/5G 室内覆盖升级并降低改造成本。For legacy office buildings, hotels, apartments, malls, hospitals, and public buildings, upgrading 4G/5G indoor coverage while reusing existing feeders, antennas, risers, and equipment-room resources to reduce retrofit cost.

Scenario Need

方案介绍Solution Introduction

许多老旧楼宇原有室分系统、馈线、弱电井和机房条件仍可复用,但直接重建全套网络会带来高昂施工、停业协调和物业审批成本。Nusalink 通过 5G-DAS 信源扩展与多系统数字光纤直放站两类方案,在保留既有资源的基础上补充 5G 信源、远端单元和光纤分布链路,减少重新布线、拆改装修和多楼层施工范围,以更低成本完成旧网升级。Many legacy buildings still have usable indoor-distribution systems, feeders, risers, and equipment-room resources, but rebuilding the entire network creates high construction, business-interruption, and property-approval costs. Nusalink uses 5G-DAS signal-source extension and multi-system digital fiber repeater solutions to add 5G sources, remote units, and fiber-distribution links while reusing existing assets, reducing rewiring, renovation impact, and multi-floor construction scope.

Core Capabilities

核心能力Core Capabilities

既有资源复用Existing Asset Reuse

优先复用原有 DAS、馈线、室内天线、弱电井和机房条件,减少拆改和重新布线。Reuse existing DAS, feeders, indoor antennas, risers, and equipment-room conditions first to reduce demolition, reconstruction, and rewiring.

DAS 5G 信源扩展DAS 5G Signal-Source Extension

在近端侧叠加 5G 信源,通过远端单元和既有室分覆盖范围完成 5G 演进。Add a 5G signal source at the near end, then use remote units and existing indoor-distribution coverage to evolve toward 5G.

数字光纤直放站Digital Fiber Repeater

通过 MU/RU 和光纤链路把多系统信号远距离分布到楼层、地下室和弱覆盖区域。Use MU/RU units and fiber links to distribute multi-system signals over distance to floors, basements, and weak-coverage areas.

分阶段升级Phased Upgrade

可先覆盖高投诉楼层、地下空间和重点公共区域,再逐步扩展到全楼。Start with high-complaint floors, underground areas, and priority public zones, then expand gradually to the whole building.

降低改造成本Lower Retrofit Cost

减少新布线、新机房和大规模装修协调,降低旧网升级一次性投入。Reduce new cabling, new equipment rooms, and large renovation coordination, lowering one-time legacy-network upgrade investment.
