Exploration and Application of a Shared Digital Flat Deep Coverage Indoor Distribution System
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.
