Description

Technical Field

[0001] This utility model relates to the technical field of 5G mobile communication indoor distribution system, and more specifically, to a bandwidth adaptive digital wireless repeater. Background Technology

[0002] Currently, operators are continuously optimizing network quality to meet changing service and coverage needs. While signal coverage is typically achieved using base stations, many low- to medium-value scenarios utilize active distribution systems or repeaters for coverage to optimize return on investment.

[0003] Operators choose different indoor coverage solutions based on varying capacity requirements, ease of construction, and equipment costs. Currently, indoor coverage solutions can be broadly categorized into three types: distributed picocell base stations, fiber optic repeaters, fiber optic distribution systems, coaxial cable distribution systems, and wireless repeaters, among others.

[0004] To provide users with a better network experience, operating networks are regularly optimized and adjusted. If the coverage plan cannot adapt accordingly, it will require costs such as property management coordination, network reconstruction, and subsequent equipment maintenance. Therefore, it is necessary to provide a bandwidth-adaptive digital wireless repeater. Utility Model Content
