Innovation Solution
A wireless system using a bidirectional high-speed data modem/router connected via a radio transceiver to a coaxial cable, which splits RF and AC signals, converts AC to DC power, and uses heating/cooling devices, allowing wireless communication through a window without requiring roof access, utilizing a housing with a splitter, radio transceivers, and antennas for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional HFC network connection is installed using conventional methods, then reliable Internet, voice, and data services are provided, but high installation costs and requirement for roof rights increase complexity and limit market expansion
Solution Approach 1:
The patent replaces the traditional mechanical installation system (roof mounting, physical cabling through building structures) with an electromagnetic field-based wireless communication system. The modem/router establishes Internet connectivity through wireless radio frequency transmission between antennas, eliminating the need for physical roof access and complex building penetration work while maintaining reliable service delivery to commercial facilities
Solution Approach 2:
The patent introduces a wireless modem/router as an intermediary device that converts traditional HFC network signals into wireless communications. This intermediary translates the connection method from direct physical cable installation to wireless transmission, serving as a bridge between the HFC network infrastructure and client devices without requiring direct physical access to building roofs or structures
2Device complexity
If wireless communication is implemented without roof access, then installation complexity and costs are reduced, but signal transmission reliability may be compromised
Solution Approach 1:
The patent employs dynamic signal processing and adaptive transmission techniques in the wireless modem/router to maintain reliable communication despite the absence of direct line-of-sight paths. The system dynamically adjusts transmission parameters, uses signal diversity through multiple antennas, and adapts to changing environmental conditions to ensure consistent signal quality and connection reliability for Internet, voice, and data services
