Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current repeaters are not configured to operate effectively with fiber optic signals, leading to signal loss and limited coverage, especially in large areas like university campuses or skyscrapers, where traditional RF mode repeaters fall short in providing a reliable and loss-less signal distribution.
Innovation Solution
A repeater system that can operate in both RF mode and fiber optic mode, allowing for RF to fiber optic signal conversion and back, with the option to bypass or attenuate amplification before conversion to reduce noise and power, enabling efficient signal distribution over wider areas without excessive power amplification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional RF mode repeaters are used, then the repeater can amplify and filter signals, but signal loss occurs and coverage is limited in large areas
Solution Approach 1:
The patent introduces an intermediary fiber optic communication system between the repeater and remote antenna units. The repeater converts RF signals to fiber optic signals, which transmit them losslessly over long distances through fiber optic cables, eliminating the signal loss problem of traditional RF mode repeaters in large area coverage scenarios.
Solution Approach 2:
The patent replaces the traditional RF-based signal transmission mechanism with a fiber optic communication system. RF signals are converted to fiber optic signals for transmission, and then converted back to RF signals at the remote antenna units, providing a more efficient and loss-less transmission method for large area coverage.
2Power
If excessive power amplification is applied, then signal strength increases, but noise and power consumption increase
Solution Approach 1:
The patent extracts the amplification function from the RF signal path and places it in the fiber optic domain. By converting RF signals to fiber optic signals before transmission, the system eliminates the need for excessive RF power amplification that would generate noise, while still providing sufficient signal strength at the remote locations through fiber optic transmission.
3Area of stationary object
If multiple repeaters are deployed to increase coverage, then coverage volume increases, but device complexity and cost increase
Solution Approach 1:
The patent segments the coverage area into zones served by remote antenna units connected via fiber optic communication to a central repeater. This segmentation allows for loss-less signal distribution across large areas without requiring multiple repeaters, as the fiber optic network can span longer distances and cover wider areas with fewer nodes.
