Network Tester Using Wireless Access Point for Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network testing devices are bulky, expensive, and lack a compact form factor while providing comprehensive network diagnostics, necessitating a solution for smaller, cost-effective devices that maintain functionality.
Innovation Solution
A network testing device with a wireless local area network (WLAN) interface that communicates diagnostic information to a client device, utilizing a processor and display to show network conditions via LEDs, and optionally powers itself using PoE or an internal source, allowing for a captive portal and IP address bridging to provide detailed diagnostic information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional network testing devices use high resolution displays and additional processing power, then network testing functionality is improved, but device size and cost increase
Solution Approach 1:
The patent introduces a wireless access point as an intermediary device that offloads the display function to a remote client device. The network tester itself remains small and simple, while the wireless access point handles the visualization of network diagnostics through a graphical user interface on the client device, thus resolving the contradiction between functionality and device size.
Solution Approach 2:
The system divides the network testing functionality into separate components: the network tester collects diagnostic data through simple protocol implementations, while the wireless access point and client device handle the complex tasks of data processing, visualization, and user interaction. This segmentation allows each component to be optimized independently, keeping the tester compact while maintaining comprehensive testing capabilities.
2Adaptability or versatility
If conventional network testing devices include high resolution displays and additional processing power, then network testing functionality is improved, but manufacturing cost increases
Solution Approach 1:
By introducing the wireless access point as an intermediary, the patent eliminates the need for expensive high-resolution displays and powerful processors in the network tester itself. The tester can use simple, cost-effective components while the wireless access point (which may be a standard router) provides the necessary display and processing capabilities, significantly reducing manufacturing costs.
Solution Approach 2:
The system creates a virtual copy of the display and processing functions by implementing a graphical user interface over the wireless network. Instead of physically including expensive display hardware in the tester, the system uses software-based visualization on the client device, effectively copying the display function through communication protocols rather than physical hardware.
3Volume of moving object
If the network testing device uses a wireless access point to communicate diagnostics, then device size is reduced, but network complexity increases
Solution Approach 1:
The wireless access point serves multiple functions: it provides wireless connectivity for the network tester, acts as a gateway for communicating diagnostics to client devices, and can function as a standard router for network operations. This multi-functionality reduces the need for separate dedicated components, managing network complexity while enabling compact device design.
Data Source
AI summary
A apparatus for network testing includes a network port adapted to receive data from the test network and one or more network interfaces of a wireless access point in operative communication with the network port. The one or more network interfaces generates a wireless local area network (WLAN) that communicates diagnostic information of the test network to a client device and causes the client device to display the diagnostic information.
