Modular Transceiver for Data Distribution via TV Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for distributing data packets in wireless networks, such as those used in GSM, 3G, and 4G, face challenges with inefficient transmission parameters and limited range due to antenna cable losses and the need for dedicated cabling, software installations, and suboptimal signal processing.
Innovation Solution
A system comprising a stationary modular transceiver device with an Outdoor Unit (ODU) and Indoor Unit (IDU) that utilizes existing satellite or terrestrial installations to optimize radio path losses, providing direct visibility to the base station and integrating a 'Smart Antenna System' for improved signal quality and range, without requiring new cabling or software installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated cables are installed for outdoor antennas to improve transmission parameters, then signal quality is improved, but installation complexity and cost increase significantly
Solution Approach 1:
The patent makes the existing television cable infrastructure serve dual purposes: transmitting both traditional television signals and data packets for wireless network access. By enabling the cable to carry both TV and Internet data simultaneously through frequency division multiplexing, the system eliminates the need for separate dedicated cabling, thereby reducing installation complexity while maintaining signal quality.
2Reliability
If outdoor antennas are used with long cables to improve transmission parameters, then signal reception is improved, but energy losses increase significantly
Solution Approach 1:
The patent extracts the data transmission function from the traditional indoor router setup and relocates it to an outdoor unit that can be positioned near the antenna. This allows the system to use the existing television cable infrastructure for data transmission while minimizing cable length and associated energy losses, as the outdoor unit processes signals close to the antenna source.
3Ease of operation
If software and drivers are installed on USB modems to enable data packet distribution, then connectivity is achieved, but system reliability decreases due to potential software conflicts
Solution Approach 1:
The patent replaces the software-dependent USB modem architecture with a hardware-based solution. The outdoor unit and indoor unit communicate through standardized physical interfaces and protocol-based data transmission, eliminating the need for user-installed drivers and connection manager software. This hardware-centric approach reduces software conflicts and improves system reliability while maintaining ease of operation.
4Ease of operation
If indoor routers are used for wireless network distribution, then ease of operation is improved, but transmission parameters and range are limited
Solution Approach 1:
The patent divides the wireless network distribution system into two separate functional units: an outdoor unit that handles signal reception and initial processing near the antenna, and an indoor unit that provides user-friendly wireless distribution inside the building. This segmentation allows the outdoor unit to optimize for transmission parameters and range while the indoor unit maintains ease of operation, combining both advantages in a single system.
