Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks with multiple access points often suffer from service degradation due to improper placement of access points, leading to inconsistent quality of service, increased maintenance costs, and customer dissatisfaction, as current testing methods are inadequate for optimizing network performance across multiple access points simultaneously.
Innovation Solution
A distributed test system comprising a master controller, user interface device, and wireless client devices that assess network performance by identifying the strongest access points, running test routines, and generating heat maps to optimize access point placement and channel assignments, thereby minimizing interference and maximizing coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If technicians manually test wireless network quality at each location, then network performance can be validated, but the process becomes time-consuming and costly especially in multi-story buildings
Solution Approach 1:
The system divides the testing function into multiple distributed wireless client devices placed at different locations throughout the premises. Each client device independently performs testing at its location, eliminating the need for a single technician to physically visit each spot. The master controller coordinates these distributed devices to collectively validate network performance across the entire multi-story building.
Solution Approach 2:
The wireless client devices automatically perform testing routines and report results to the master controller without requiring manual intervention at each location. The system self-configures by having client devices automatically identify and connect to the strongest access point, then autonomously executes testing and generates reports, freeing technicians from repetitive manual testing tasks.
2Ease of manufacture
If access points are placed based on convenience rather than performance criteria, then installation is easier, but network performance degrades due to interference and attenuation
Solution Approach 1:
The system implements a feedback loop where wireless client devices continuously monitor network performance metrics such as signal strength, interference levels, and throughput at various locations. The master controller collects this data and uses it to evaluate access point placements. Technicians can then adjust access point positions based on quantitative performance feedback rather than relying on convenience, ensuring optimal network performance while maintaining installation efficiency.
Solution Approach 2:
The system performs preliminary testing and analysis during the installation phase itself. Wireless client devices are deployed to test the network configuration before final deployment, allowing technicians to identify and correct placement issues early. This preliminary validation ensures that access points are optimally positioned from the start, preventing performance degradation that would require costly reinstallation later.
3Adaptability or versatility
If existing wireless network devices are used without testing capability, then device compatibility is maintained, but network optimization cannot be performed
Solution Approach 1:
The system employs universal wireless client devices that can interface with and test multiple types of access points and network configurations. These devices are designed to work across different wireless standards and device types, maintaining broad compatibility. Simultaneously, they provide advanced testing and optimization capabilities that enhance network productivity, effectively bridging the gap between device versatility and optimization capability.
4Reliability
If technicians reposition access points to improve performance, then network quality can be enhanced, but the entire validation process must be repeated adding to costs
Solution Approach 1:
The system implements dynamic, continuous monitoring using distributed wireless client devices that track network performance in real-time. Rather than requiring static validation after each access point repositioning, the system continuously collects performance data and provides feedback. This allows technicians to make informed repositioning decisions based on live data, and the system automatically updates performance validation without requiring complete re-testing, significantly improving optimization efficiency while maintaining network quality.

AI summary
A system for determining and optimizing wireless network performance of a network having at least two access points comprises a plurality of wireless instruments configured to send, receive, and measure received wireless signals in a monitored area. The system further comprises a master controller in communication with the wireless instruments to form a distributed wireless network testing solution. The master controller is configured to send wireless signals to and receive wireless signals from the wireless instruments, measure the received wireless signals, and perform an analysis of the wireless signals to determine a radio frequency environment performance of the distributed wireless network based at least in part on the wireless signals.
