14.7.2 Lessons Learned (Testing)

Key Testing Insights:

1. Predictive RF Modeling Is Reliable
   • Ekahau predictive survey: 97% coverage
   • Actual validation: 97% coverage (perfect match)
   • Lesson: Trust predictive tools, but always validate post-deployment

2. iPerf3 Testing Requires Multiple Streams
   • Single stream: 2.8 Gbps (TCP window limitation)
   • 4 parallel streams: 4.5 Gbps (saturates link)
   • Lesson: Use -P 4 flag in iPerf3 for accurate WiFi 7 testing

3. MLO Failover Is Truly Seamless
   • Expected: <10ms failover
   • Actual: 4.2ms, 0 packets lost
   • Lesson: MLO is production-ready, marketing claims validated

4. User Satisfaction Correlates with RSSI
   • RSSI >-65 dBm: 95% satisfaction
   • RSSI -65 to -70 dBm: 85% satisfaction
   • RSSI <-70 dBm: 60% satisfaction (complaints)
   • Lesson: Dense AP deployment justified (1 per 1,333 sq ft)

5. Security Testing Identifies "Hygiene" Issues
   • No critical vulnerabilities found
   • Minor issues: ARP inspection, DHCP snooping (simple fixes)
   • Lesson: WiFi 7 + WPA3 + 802.1X is inherently secure

6. UAT Surveys Provide Valuable Insights
   • Open-ended feedback: "Cable-free workspace" most-cited benefit
   • Quantitative: 92% satisfaction
   • Lesson: Both quantitative + qualitative data essential

7. Regression Testing After AP Additions
   • Added 2 APs (MUM-F6-AP16, AP17) after pilot
   • Re-ran performance tests (validation)
   • Result: Coverage improved 97% → 99%
   • Lesson: Always re-test after infrastructure changes
