Solution Overview

Problem

Current home Wi-Fi technology struggles to meet the demands of high-bandwidth services such as high-definition videos and games due to limitations in bandwidth and anti-interference performance, making it unreliable for concurrent data transmission.

Innovation Solution

A network routing device that utilizes both wireless and wired communication methods, using radio frequency units and wired communication modules to transmit signals, allowing for concurrent transmission and improving reliability by detecting channel indicators before data signal conversion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current home Wi-Fi technology is used, then typical data services such as SMS messages and voice calls can be supported, but high bandwidth services such as high-definition videos and games cannot meet requirements due to limitations on bandwidth and anti-interference

Engineering Contradiction:
Improvesignal transmission reliabilityVSAvoidservice type adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the transmission medium into two independent parts: a wireless transmission module (Wi-Fi radio frequency unit) and a wired transmission module (power line communication module). Each module handles specific transmission tasks independently, allowing the system to support both typical services (SMS, voice calls) and high-bandwidth services (HD videos, games) simultaneously while maintaining signal transmission reliability through the redundant wired connection.

Inventive Principle:
Principle #1Segmentation

2Reliability

If dual transmission modes (wireless and wired) are implemented, then signal transmission reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesignal transmission reliabilityVSAvoidtransmission module complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the power line serve dual functions: it simultaneously provides electrical power supply to the network routing device and acts as a wired data transmission medium through the power line communication module. This multi-functionality approach avoids the need for separate dedicated wired communication infrastructure, thereby reducing overall device complexity while maintaining dual transmission mode capability and improving signal transmission reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If power line communication module is connected to power line, then cabling complexity is reduced, but channel quality may be affected

Engineering Contradiction:
Improvecabling complexityVSAvoidchannel quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent incorporates a channel indicator detection unit that continuously monitors the quality of the power line communication channel. Based on the detected channel quality feedback, the system dynamically adjusts transmission parameters or switches between wireless and wired transmission modes to maintain reliable data transmission. This feedback mechanism ensures that while the power line connection simplifies cabling, the system can adapt to channel quality variations and maintain transmission reliability.

Inventive Principle:
Principle #23Feedback

AI summary

Embodiments of the present invention disclose a network routing device, a network data transmission method, and a network access device. The network routing device includes a first network transmission processing module, at least one first radio frequency unit, a first antenna corresponding to the first radio frequency unit in quantity, and at least one first wired communication module. The first network transmission processing module is configured to: convert a received data signal into at least two baseband signals, send one baseband signal to the first radio frequency unit, and send another baseband signal to the first wired communication module. Correspondingly, the first radio frequency unit converts the baseband signal into a radio frequency signal and then sends the radio frequency signal by using the first antenna, and the first wired communication module converts the baseband signal into a network signal that can be transmitted in a wired transmission medium and then sends the network signal to the wired transmission medium for transmission. According to the network routing device in the embodiments of the present invention, a signal can be transmitted in both a wired manner and a wireless manner. This improves signal transmission reliability.
