Wireless Network Extender Dual-Channel Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless mesh network architectures face significant challenges when the wireless network extender and router disconnect, leading to a 'diagnostic unavailable' state that requires manual on-site diagnosis and repair, resulting in high manpower costs and long recovery times.
Innovation Solution
A network system with a redundancy mechanism using different communication protocols, where the wireless network extender connects to the network provider through either a primary or secondary communication channel, allowing for automatic diagnosis and management, with the primary and secondary channels employing distinct communication protocols such as Wi-Fi and cellular protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication channel is used for mesh network connectivity, then device complexity is reduced, but reliability deteriorates when the channel becomes unavailable
Solution Approach 1:
The communication channel is segmented into two distinct types: a first communication channel for data transmission and a second communication channel for management and diagnosis. This segmentation allows the system to maintain reliability by switching to the second channel when the first fails, while keeping each individual channel relatively simple in structure.
Solution Approach 2:
The system changes the communication protocol parameter by using different protocols for the two channels (e.g., Wi-Fi for the first channel and cellular for the second channel). This parameter change enables the system to overcome the limitations of a single protocol and achieve better reliability without excessive complexity.
2Loss of time
If manual on-site diagnosis is performed when connection fails, then measurement precision is maintained, but loss of time increases
Solution Approach 1:
The system implements self-service by enabling the network management server to automatically diagnose and manage mesh network devices through the second communication channel when the first channel fails. This eliminates the need for manual on-site intervention, significantly reducing recovery time while maintaining full diagnostic capability through automated procedures.
Solution Approach 2:
The second communication channel acts as an intermediary that enables remote diagnosis and management when the primary data transmission channel fails. This intermediary channel allows the network management server to communicate with mesh devices without requiring physical presence, thus reducing recovery time while maintaining automation.
3Productivity
If engineers are dispatched for on-site repair, then ease of operation is maintained, but productivity decreases
Solution Approach 1:
The system replaces the mechanical approach of dispatching engineers with physical travel and on-site operations with an automated electronic diagnosis system. The second communication channel enables remote management and diagnosis, substituting the mechanical dispatch process with electronic automation, thereby improving productivity while maintaining ease of operation through standardized automated procedures.

AI summary
The disclosure discloses a network system, a wireless network extender, and a network provider. The network system includes a network provider, a wireless network router, and a wireless network extender. The wireless network extender includes a communication unit and an extension unit. The wireless network extender connects to the wireless network router through a first communication channel provided by the communication unit and communicates with the network provider through the wireless network router, or communicates with the network provider through a second communication channel provided by the extension unit. When the first communication channel is unavailable, the wireless network extender connects to the network provider through the second communication channel. The first communication channel and the second communication channel use different communication protocols. The disclosure can provide a mesh network with a redundancy mechanism for diagnosis/management using different communication protocols.
