Quality assurance in testing smart home appliances
Abstract
Fast-paced growth in IoT hardware and complex software integration presents a practical quality control challenge for modern household devices. This paper outlines an empirical quality assurance method tailored for testing Wi-Fi-enabled home appliances. Focusing on dynamic signal stability, transmission delays, and data loss, we evaluated a commercial robotic vacuum cleaner across realistic operational setups involving distance variations and structural walls. We collected real-time metrics for Received Signal Strength Indicator (RSSI), packet loss, latency, and jitter. To create a definitive threshold for pass/fail decisions, we combined these parameters into a weighted Integral Connection Quality Index ($Q$). Physical test runs show a clear operational drop-off below –70 dBm RSSI. At this point, packet loss surpasses 4.5% and latency doubles, pulling $Q$ under the critical 0.60 mark and triggering application control failures. Repeated measurements confirmed solid test consistency, with the coefficient of variation staying under 8%. Overall, this study offers testing labs and manufacturers a concrete, metrologically sound process to define product compliance and limit post-sale warranty claims.
Keywords: smart home appliances, quality assurance, functional testing, Wi-Fi connectivity, integral quality index, data transmission reliability, RSSI, packet loss
