Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static spectrum allocation is used, then spectrum assignment is simple, but spectrum utilization efficiency deteriorates due to severe underutilization
Solution Approach 1:
The patent implements dynamic spectrum allocation where the base station continuously monitors channel occupancy and dynamically assigns spectrum resources to different access points based on real-time traffic demands and channel conditions, transforming static allocation into a flexible, adaptive system that optimizes utilization
Solution Approach 2:
The system changes allocation parameters such as time slots, frequency bands, and power levels based on detected traffic patterns and channel availability, allowing the spectrum to be reassigned dynamically to meet varying network demands and eliminate underutilization
2Area of stationary object
If more wireless access points are introduced to extend communication range, then coverage area is improved, but latency increases
Solution Approach 1:
The patent introduces a spectrum sharing mechanism as an intermediary that coordinates communication between multiple access points, allowing them to share spectrum resources efficiently and reducing the need for additional infrastructure while maintaining low latency through coordinated spectrum access
3Ease of manufacture
If conventional Wi-Fi mesh topologies are used, then deployment is simple, but network resilience deteriorates due to shared channel contention and interference
Solution Approach 1:
The patent segments the spectrum into multiple time slots and frequency channels, allowing different access points to transmit simultaneously without interference, thereby improving network resilience while maintaining deployment simplicity through automated spectrum management
Data Source
AI summary
A virtual fiber communication system includes a central cloud server that obtains telemetry information from network nodes of wireless backhaul mesh network. The telemetry information includes spectrum occupancy information and UE positioning information. The central cloud server obtains, via blockchain-based spectrum broker nodes, frequency spectrum availability metadata and custom-defined spectrum access parameters of spectrum owner nodes. The central cloud server detects spectrum availability variations across network nodes and determines different routing paths for the first type of UEs designated as premium users. Based on the detected spectrum availability variations across the network nodes and the determined different routing paths, control signals are generated and communicated to the network nodes to assign data streams onto rented or leased spectrum frequencies. One of the determined routing paths is selected for delivery of the data streams to the first type of UEs to meet the custom-defined spectrum access parameters.
