Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF repeaters struggle with signal interference, noise amplification, and inability to distinguish between downlink and uplink data, leading to inconsistent performance in wireless communication networks, particularly in challenging environments with obstacles or moving vehicles.
Innovation Solution
Implementing multiple repeater aggregation (MRA) systems that utilize multiple RF repeaters to enhance coverage, reliability, and channel capacity by selecting optimal communication paths, combining signal copies, and employing joint transmission across diverse beams and streams, while leveraging smart repeaters for advanced beam management and load balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional RF repeaters are used to extend coverage, then coverage area is improved, but signal interference and noise amplification increase
Solution Approach 1:
The patent combines multiple RF repeaters into an aggregated system that operates as a coordinated unit. Multiple repeaters aggregate received signals and forward them through different paths simultaneously, creating signal diversity that reduces interference and noise amplification while extending coverage area.
Solution Approach 2:
The system segments the signal transmission path by using multiple independent RF repeaters that each handle portions of the communication network. This segmentation allows signals to be transmitted through multiple parallel paths, reducing the impact of interference on any single path while maintaining overall coverage.
2Reliability
If multiple RF repeaters are aggregated to enhance coverage and reliability, then system complexity increases
Solution Approach 1:
The RF repeaters in the aggregation are designed with multi-functionality, capable of performing signal reception, signal combining, and signal forwarding across multiple paths. This universal capability reduces the need for specialized components and simplifies the overall system architecture while maintaining high reliability.
Solution Approach 2:
The aggregated repeater system operates autonomously by automatically selecting optimal signal paths and coordinating signal transmission without requiring complex centralized control. Each repeater independently processes signals while contributing to the overall reliability, reducing system management complexity.
3Length of moving object
If RF repeaters amplify signals to extend range, then transmission distance is improved, but noise amplification increases
Solution Approach 1:
Multiple RF repeaters combine and aggregate signals before forwarding them through different paths. This signal combining approach allows the system to extend transmission distance while the diversity of multiple paths reduces noise amplification, as not all paths experience the same noise conditions.
Solution Approach 2:
The system dynamically adjusts signal processing operations based on real-time channel conditions. By adapting the signal combining and forwarding operations to current network conditions, the system optimizes the balance between extending transmission distance and minimizing noise amplification.
