Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal boosters for wireless communication often fail to provide effective amplification and filtering for both uplink and downlink signals, leading to inconsistent network performance, especially in areas with weak signal strength, and may not comply with regulatory standards for noise and gain limits.
Innovation Solution
A signal booster system that includes integrated device and node antennas, capable of amplifying and filtering both uplink and downlink signals bi-directionally, with features such as simultaneous bypass paths, switchable band pass filters, and power amplifiers to optimize signal strength and comply with regulatory requirements, and can be configured for various frequency bands and standards like LTE and 5G.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used for both uplink and downlink signals, then device complexity is reduced, but signal quality and network performance become inconsistent
Solution Approach 1:
The patent divides the single antenna function into separate uplink antenna and downlink antenna, allowing independent optimization of each signal path. This segmentation enables dedicated signal processing for uplink and downlink, resolving the inconsistency in signal quality while maintaining manageable device complexity through modular architecture.
2Reliability
If signal amplification is applied to both uplink and downlink signals, then network performance is improved, but noise and gain limits may exceed regulatory standards
Solution Approach 1:
The patent applies different amplification characteristics to uplink and downlink signal paths based on their specific requirements. By configuring separate amplification levels and filtering parameters for each direction, the system optimizes network performance locally in each path while ensuring that noise and gain limits comply with regulatory standards through targeted control rather than uniform amplification.
3Reliability
If separate uplink and downlink antenna paths are implemented, then signal amplification and filtering effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines the separate uplink and downlink signal processing functions into a single integrated signal booster device. By merging the amplification, filtering, and signal processing capabilities into one unified system with coordinated control, the patent achieves effective separate path processing while avoiding the complexity of multiple independent devices, thus resolving the contradiction between effectiveness and complexity.
