How a Wi-Fi Site Survey Enhances Performance

Introduction

Floor plans aren’t the real world. Materials, neighbors, and devices create RF surprises. A Wi-Fi site survey converts assumptions into measurements, revealing exactly how your network behaves—and how to fix what doesn’t.

What a Professional Survey Includes

Passive surveys: Measure signal and noise to generate heatmaps of RSSI and SNR.
Active surveys: Test throughput, latency, and roaming; validate voice readiness.
Spectrum analysis: Identify non-Wi-Fi interferers (microwaves, cordless phones, cameras, Bluetooth beacons).
Validation of design targets: Confirm channel plans, power levels, and AP placement per area type.

Common Issues Found

  • APs placed for aesthetics, not RF (pretty ceilings, poor signal) 
  • Co-channel interference from over-dense deployments 
  • Sticky clients due to poor roaming thresholds 
  • Hidden coverage holes behind metal, glass, or elevator shafts 

From Findings to Fixes

Tune channels and power; add or relocate APs; split SSIDs and apply proper band steering; adjust minimum bitrates; and fix cabling or PoE limitations. Document before/after metrics to prove improvements.

When to Survey

New builds, post-renovations, high complaint volumes, major tenant changes, or upgrades to Wi-Fi 6/7. Annual surveys catch drift before it becomes pain.

Outcome and ROI

Surveys cut ticket noise, improve user satisfaction, and prevent over-building. The report also becomes a valuable artifact for future moves and audits.

Conclusion & CTA

If you’ve never measured it, you’re guessing. SpecOp Secure performs site surveys that lead to real fixes—not just prettier heatmaps. Need a fast diagnostic or full validation? We’ll scope it today.
