Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Mobile Backhaul solutions require complex and cost-ineffective management systems for combining optical transport systems with Microwave Radio transport systems, and lack flexible capacity distribution, especially in areas without adequate fiber infrastructure.
Innovation Solution
An optical network unit that integrates an optical module with an optical-electric interface and a control unit, allowing for wireless coupling with a microwave radio link or other interfaces, sharing a common management system and enabling flexible capacity distribution by using Ultra-Dense Wavelength Division Multiplexing (UDWDM) or Dense Wavelength Division Multiplexing (DWDM) coherent networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Mobile Backhaul solutions combine optical transport systems with Microwave Radio transport systems, then capacity and coverage are improved, but management system complexity and cost increase
Solution Approach 1:
The patent merges optical transport and microwave radio transport systems into a unified Optical Network Unit that handles both transmission types. The ONU integrates optical modules for fiber connectivity and radio frequency interfaces for wireless backhaul, consolidating previously separate management systems into a single device that manages both transmission media and protocols.
Solution Approach 2:
The Optical Network Unit is designed as a universal device that can perform multiple functions: optical signal reception and transmission, radio frequency signal processing, capacity allocation across different media, and unified network management. This multi-functional design eliminates the need for separate management systems for optical and microwave components.
2Productivity
If extensive fiber infrastructure is deployed to provide adequate capacity, then data transmission capacity is improved, but infrastructure cost and deployment complexity increase
Solution Approach 1:
The patent introduces microwave radio links as an intermediary transmission medium between the optical network unit and mobile base stations. This allows capacity to be extended to areas where fiber deployment is impractical or too costly, using existing radio infrastructure or temporary wireless links as a bridge.
Solution Approach 2:
The system dynamically changes transmission parameters by switching between optical and radio frequency modes based on location requirements. In areas with fiber infrastructure, optical transmission provides high capacity; in areas without fiber, the same ONU uses radio frequency transmission to provide adequate capacity, adapting to local conditions.
3Measurement precision
If separate management systems are used for optical and radio communication systems, then system control precision is improved, but operational expenses increase
Solution Approach 1:
The patent combines separate management functions for optical and radio systems into a single integrated management unit within the ONU. This unified controller manages both transmission types with centralized logic, reducing the operational overhead of maintaining separate management systems while preserving precise control through integrated monitoring and allocation algorithms.
