Professional Wireless Site Survey Using Ekahau — Southern California
WCC Technologies Group performs wireless site surveys for Southern California businesses — predictive RF modeling before deployment, passive diagnostic walks for existing networks, and active validation surveys after installation. Ekahau Pro on every engagement, heat map deliverables at closeout.
Wireless Site Surveys That Drive Wireless Design — Not Just Validate It
A wireless site survey is the measurement and analysis process that answers the questions no product spec sheet can answer: How does RF propagate through your specific building construction? Where are the interference sources? How many APs are needed at what locations to serve your device density and application requirements? What channel plan prevents co-channel interference between adjacent APs?
WCC Technologies Group performs wireless site surveys using Ekahau Pro — the industry standard for professional RF analysis. We conduct pre-deployment predictive surveys for new installations, passive and active surveys for troubleshooting existing networks, and post-installation validation surveys that document network performance after deployment with heat maps and channel utilization data.
Standalone wireless site surveys are available for organizations that need RF analysis independent of an installation project — whether you're planning a new deployment with another integrator, troubleshooting a network that isn't performing as expected, or validating infrastructure you've inherited. For organizations ready to move from survey to deployment, WCC handles the full enterprise WiFi installation scope.
Wireless site survey only, or survey + deployment? WCC performs standalone surveys as an independent deliverable. If the survey leads to a deployment, that scope is priced separately — you're never locked into an installation just because you engaged us for the survey.

Three Types of Wireless Site Survey — Each Answers a Different Question
The right wireless site survey type depends on where you are in your project — planning a new deployment, troubleshooting an existing network, or validating one that was just installed. WCC performs all three.
Predictive (Pre-Deployment) Survey
This survey type uses Ekahau's modeling engine to simulate RF propagation based on your floor plans and building construction materials — before any APs are installed. WCC imports your floor plans, calibrates attenuation values for walls, floors, and doors, places virtual APs at candidate locations, and produces a predicted coverage and capacity model that drives the installation design.
For new construction where physical access to the building isn't yet available, predictive surveys are the only way to design the wireless network before installation begins. For existing buildings, predictive surveys are combined with a physical walkthrough to validate attenuation assumptions.
Passive (Walk) Survey
This survey type walks the facility with Ekahau hardware while the existing network is running — measuring signal strength, SNR, channel utilization, AP coverage overlap, and interference sources at every point along the walk path. The result is a data-driven picture of how your current network actually performs in the physical environment.
Passive surveys are the standard diagnostic tool for troubleshooting underperforming networks — they reveal coverage gaps, channel conflicts, rogue APs, and interference sources that IT teams can't see from the management console alone.
Active (Validation) Survey
This survey type connects a client device to the wireless network and measures actual throughput, packet loss, and roaming behavior while walking the facility — testing real network performance from a client's perspective. Post-installation active surveys are the definitive proof that a newly deployed network performs to specification.
WCC includes a post-installation active validation survey in every enterprise WiFi deployment and delivers the heat map and performance report as part of project closeout. Organizations can also commission standalone active surveys to validate networks installed by other contractors.
Wireless Site Survey Report Deliverables
A survey is only as valuable as the documentation it produces. Here's exactly what WCC delivers at the conclusion of every engagement.
Signal Strength Heat Map
Floor plan overlay showing RSSI coverage across the facility — color-coded by signal level. Identifies coverage gaps, areas of adequate coverage, and zones where signal is stronger than necessary.
SNR Heat Map
Signal-to-noise ratio mapped across the facility. SNR is a more meaningful performance indicator than raw signal strength — a strong signal in a high-noise environment produces poor throughput. SNR mapping reveals interference problems that RSSI maps miss.
Channel Utilization Map
Per-channel airtime utilization mapped across the facility — showing which channels are congested and where co-channel interference between adjacent APs is degrading performance.
AP Placement Plan
Floor plan annotated with recommended AP locations, mounting heights, and orientations — with justification for each placement decision based on the survey data.
Interference & Rogue AP Report
Identification of all detected SSIDs, rogue APs, and non-WiFi interference sources (Bluetooth, microwave, DECT phones, video) in the RF environment — with location estimates where Ekahau can triangulate.
Written Findings & Recommendations
A written report summarizing survey findings, identified issues, AP count and model recommendations, channel plan, cabling requirements, and PoE budget — formatted for both technical and non-technical stakeholders.
Wireless Site Surveys Across Southern California
Every building type presents a different RF challenge. Dense concrete, metal stud construction, high-bay steel racking, medical equipment interference, and outdoor environments all require different wireless site survey approaches and design solutions.
Corporate Office
Open office density, private office coverage, conference room capacity — with particular attention to high-device-count meeting rooms that demand capacity planning, not just coverage modeling.
Healthcare
Hospital and clinic environments require interference analysis around medical equipment, roaming validation for mobile carts, and coverage verification in areas with lead-lined walls and dense construction.
K–12 & Higher Education
Classroom buildings with 30–60 devices per room demand high-density capacity wireless site surveys — not standard coverage walks. Surveys model per-classroom device load and verify the channel plan handles concurrent classroom sessions.
Government Facilities
Government buildings often feature heavy concrete construction, older renovation layers, and security requirements that affect AP placement — requiring accurate attenuation modeling in the wireless site survey.
Warehouse & Distribution
High-bay metal racking creates severe multipath interference. A warehouse survey must be conducted at floor and aisle level — not modeled from ceiling height — to identify dead zones behind racking that standard coverage maps miss.
Outdoor & Campus
Outdoor surveys account for Fresnel zone clearance, ground reflection, interference from neighboring networks, and handoff boundary design between outdoor APs and interior coverage.
Our Wireless Site Survey Process
A wireless site survey that produces actionable results follows a defined methodology — not a walk through the building with a smartphone app.
Scope & Floor Plan Review
We review your floor plans, building construction type, device inventory, application requirements, and current pain points before arriving on site. Ekahau floor plans are calibrated and attenuation values assigned to wall types before the walk begins.
On-Site RF Measurement
WCC's surveyor walks the facility with Ekahau hardware — recording GPS-calibrated signal measurements, channel utilization data, and interference sources at every point. High-density areas receive additional measurement passes at device height.
Data Analysis & AP Design
Survey data is analyzed in Ekahau to identify coverage gaps, interference sources, channel conflicts, and capacity constraints. AP locations are placed and modeled against your device density and throughput requirements.
Channel Plan Design
A channel plan is designed for the specific AP layout — assigning channels to minimize co-channel interference between adjacent APs on 2.4 GHz, 5 GHz, and 6 GHz bands, and accounting for neighboring networks visible in the RF environment.
Report Generation
Heat maps, AP placement plan, interference report, channel plan, cabling requirements, and written findings compiled into a report formatted for both technical and non-technical stakeholders.
Report Delivery & Review
The survey report is delivered digitally, with a review call to walk through findings and recommendations. If the survey proceeds to a WCC installation, the survey data directly drives the installation design — no re-work, no re-survey.
Why Organizations Choose WCC for Wireless Site Surveys
A wireless site survey is only as useful as the methodology behind it and the clarity of the deliverables. Here's what separates a WCC survey from a coverage walk.
Ekahau Pro — Not a Smartphone App
WCC surveys use Ekahau Pro with calibrated hardware — the same platform used by enterprise wireless engineers at major technology companies. Not a free WiFi analyzer app, not a vendor-supplied tool with limited capability.
Capacity, Not Just Coverage
WCC surveys model device density and per-AP client load — not just whether signal reaches a location. A network with adequate coverage can still fail when 40 devices connect to an AP designed for 20. Capacity planning is built into every survey.
Actionable Deliverables
Survey reports include AP placement floor plans, heat maps, channel plan, cabling run counts, and PoE budget — everything needed to scope and price an installation, not just a list of findings with no design guidance.
Survey + Deployment Available
WCC handles both the wireless site survey and the enterprise WiFi installation — so the survey data directly drives the installation design. No translation loss between the surveyor's recommendations and the installer's execution.
Vendor-Neutral Recommendations
WCC survey reports recommend the right AP platform for your requirements — not the platform with the highest margin. The survey itself is objective; any installation conversation is separate.
20+ Years of RF Experience

Wireless Site Survey — Frequently Asked Questions
How much does a wireless site survey cost?
Pricing depends on facility size, number of floors, survey type, and whether post-installation validation is included. A predictive survey for a single-floor commercial facility typically starts around $800–$1,500. A passive or active walk survey of a multi-floor office building ranges from $1,500 to $4,000 depending on square footage and complexity. WCC provides a fixed-price quote after reviewing your floor plans and scope requirements.
How long does a wireless site survey take?
On-site time depends on facility size and survey type. A passive walk survey of a 20,000 sq ft single-floor office typically takes 2–4 hours on site. Multi-floor buildings and high-density environments take longer due to additional measurement passes. Report generation and delivery typically takes 3–5 business days after the on-site visit. Predictive surveys for new construction can often be completed remotely in 3–5 business days once calibrated floor plans are provided.
Can you survey a facility for a deployment that another company will install?
Yes. WCC performs standalone surveys as an independent deliverable — the report and AP placement design are yours to use with any installer. We don't require a survey to lead to a WCC installation. Some organizations engage WCC for the survey specifically because they want an independent, vendor-neutral RF assessment before committing to an installation contractor or AP platform.
What is the difference between a passive survey and an active survey?
A passive survey listens to the RF environment — measuring signal strength, noise floor, channel utilization, and neighboring networks without connecting to any wireless network. This survey type connects a client device and measures actual throughput, packet loss, latency, and roaming behavior from a client's perspective. Post-installation validation surveys are typically active surveys, because you want to confirm the network performs correctly under client load, not just that signal reaches everywhere.
Do you perform wireless site surveys in Los Angeles?
Yes. WCC performs wireless site surveys across Los Angeles County — serving corporate campuses, healthcare facilities, school districts, government buildings, and warehouses in Los Angeles, Long Beach, Pasadena, Burbank, El Segundo, Torrance, and the San Fernando Valley.
