The two quality assessments are combined to derive and output an overall quality assessment for biometry measurements obtained from the image.

METHOD TO IMPROVE PHYSICAL NETWORK DESIGN BY ANALYZING SIGNAL STRENGTH AND ROAMING BEHAVIOR (18032200)

Main Inventor

Serverius Petrus Paulus PRONK

Brief explanation

The abstract describes a method for detecting issues with wireless connections in a facility using Wi-Fi roaming data. The method involves analyzing the data to identify instances where an access point (AP) disconnects from a wireless device and then reconnects without the device connecting to any other AP during that time interval. An alert is generated for any AP that exceeds a predetermined disconnect rate threshold.

• The method detects issues with wireless connections in a facility.
• It analyzes Wi-Fi roaming data to identify single-AP disconnect events.
• A single-AP disconnect event occurs when an AP disconnects from a device and then reconnects without the device connecting to any other AP.
• An alert is generated for APs with a high rate of single-AP disconnect events.

Potential Applications

• This technology can be used in various facilities such as offices, hospitals, airports, and shopping malls to monitor and detect issues with wireless connections.
• It can help improve the overall performance and reliability of wireless networks in these facilities.

Problems Solved

• The method solves the problem of detecting and identifying issues with wireless connections in a facility.
• It allows for proactive monitoring and troubleshooting of wireless networks to ensure uninterrupted connectivity for users.

Benefits

• The method provides a systematic approach to detect and analyze wireless connection issues.
• It helps in identifying APs with a high rate of single-AP disconnect events, allowing for targeted troubleshooting and optimization.
• By generating alerts for APs exceeding a predetermined threshold, it enables timely intervention and resolution of connectivity issues.
