Solution Overview
Problem
Next-generation 5G wireless networks face challenges in providing efficient backhaul connectivity from small cells to macro cells or backend systems, particularly in urban areas and indoor environments, where traditional macro cell architectures are insufficient.
Innovation Solution
The implementation of an intelligent wireless mesh network (IWMN) with smart wireless stations that offer 5G fronthaul and backhaul services, including discovery and neighbor selection, multi-active multi-path services, reporting, and backhaul control, to optimize traffic routing and maximize redundancy, reliability, and throughput, using smart antennas and supporting various architectures like vRAN, SDN, and NFV.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional macro cell architecture is used, then network coverage is provided, but backhaul connectivity efficiency deteriorates in urban areas and indoor environments
Solution Approach 1:
The network is segmented into multiple small cells rather than using a single macro cell, allowing distributed backhaul connections and improved traffic handling in dense environments
Solution Approach 2:
The patent introduces multi-path routing through discovery and neighbor selection services, adding dimensional diversity to backhaul connectivity by establishing multiple independent paths between small cells and the core network
2Reliability
If intelligent wireless mesh network with multiple paths is implemented, then redundancy and reliability are improved, but device complexity increases
Solution Approach 1:
The mesh network implements self-service through automated discovery and neighbor selection services, where nodes automatically establish and maintain multi-active paths without manual configuration, reducing operational complexity despite increased structural complexity
Solution Approach 2:
The network employs feedback mechanisms through reporting services that monitor path quality and dynamically adjust routing decisions, enabling adaptive management of multiple paths and simplifying control complexity through intelligent feedback loops
