Active Site Survey: Methodology and Use Cases

Technical Guide: Active Site Survey: Methodology and Use Cases

A wireless site survey is the foundation of any reliable enterprise WiFi deployment. Active Site Survey: Methodology and Use Cases determines whether the network will meet coverage, capacity, and roaming targets before hardware is installed — or validates that an existing deployment meets requirements. The three main survey types — predictive, passive, and active — serve different purposes and are used at different project stages.

Ekahau's toolset (AI Pro for predictive design, Sidekick 2 for RF measurement, Survey for passive/active capture, and Analyzer for packet analysis) has become the industry standard for professional WiFi site surveys. ECSE-certified engineers follow a structured methodology: requirements gathering, floor plan calibration, AP placement modelling, on-site measurement, and deliverable generation. The output — heatmaps, AP bills of material, channel plans, and coverage reports — directly feeds into procurement and deployment.

Survey Methodology and Cost Considerations

A structured survey methodology ensures consistent, repeatable results regardless of the engineer performing the work. The typical flow is: scope definition → floor plan preparation → predictive design → on-site passive survey → active survey → analysis → reporting → remediation → validation. Each step has defined inputs, outputs, and quality checkpoints. Skip a step (commonly: skipping post-deployment validation) and you risk deploying a network that looks good on paper but underperforms in practice.

Survey costs in India depend on site size, complexity, number of floors, deliverable scope, and location (metro vs Tier-2). A basic passive survey for a single-floor office (5,000 sq ft) starts around ₹15,000–25,000. A comprehensive predictive + passive + active survey for a multi-floor campus (50,000+ sq ft) with detailed reporting ranges from ₹1,00,000 to ₹3,00,000. Multi-city engagements should factor in travel costs. Value the survey against the cost of a failed WiFi deployment — redesigning and redeploying APs after installation is 3–5x more expensive than getting it right the first time.

Site Survey Methodology Steps

1. Requirements gathering — document coverage zones, device types, application SLAs (voice, video, data), and density per area
2. Floor plan preparation — obtain CAD/PDF floor plans, calibrate scale, mark wall materials and attenuation values
3. Predictive design — model AP placement in Ekahau AI Pro using wall types and antenna patterns; iterate until coverage and SNR targets are met
4. On-site passive survey — walk the floor with Ekahau Sidekick 2 capturing RSSI, noise, channel utilisation, and co-channel interference
5. Active survey — connect to the network and measure real throughput, packet loss, jitter, and roaming handoff times
6. Analysis and reporting — generate heatmaps, identify dead zones or interference sources, produce AP BOM and channel plan
7. Post-deployment validation — repeat passive/active survey after installation to confirm design targets are met

Site Survey Considerations for India

Indian enterprise sites — from IT parks in Bengaluru and Hyderabad to manufacturing facilities in Pune and Chennai — require surveyors who understand local construction. Thick RCC columns, metal partition frames in co-working spaces, and glass facades in modern towers all affect RF propagation differently. Multi-tenant buildings with shared risers require careful coordination for cabling and AP mounting. Pricing for professional site surveys in India typically ranges from ₹15,000 to ₹2,00,000+ depending on site size, number of floors, and deliverable scope. Factor in travel for multi-city or Tier-2 engagements.
