Wireless site survey in Southern California

Predictive, passive and active Ekahau surveys that put access points in the right places, with a report you can use with any installer.

The short answer

A wireless site survey measures how Wi-Fi actually behaves in your building so access points go in the right places. WCC uses Ekahau for predictive surveys before installation, passive surveys to diagnose existing networks, and active surveys to validate performance. A predictive survey for a single floor typically starts at $800 to $1,500; on-site surveys of multi-floor buildings run $1,500 to $4,000.

Survey types

Three types of wireless site survey

TypeWhat it doesWhen to use it
PredictiveModels coverage and capacity from floor plans and wall materialsNew construction, budgeting AP counts and cabling
PassiveWalks the building measuring signal, noise, channels and interferenceTroubleshooting, baselining before an upgrade
ActiveConnects a device and measures throughput, loss and roamingValidating a new install or accepting another contractor's work

What you get

Survey deliverables

Heat maps

Signal strength, signal-to-noise and channel overlap across every floor.

AP placement plan

Locations, mounting heights and counts, with the reasoning.

Channel plan

2.4, 5 and 6 GHz channels designed around neighboring networks.

Interference report

Rogue access points and non-Wi-Fi interference sources.

Cabling and PoE

Drop counts and switch power needed for the design.

Written findings

Plain-language summary for IT and leadership.

Capacity

Coverage isn't the same as capacity

A network can show strong signal everywhere and still fail when 40 laptops join one access point. We design for the number of devices and applications in each space, not just square footage, which matters most in classrooms, conference rooms, warehouses and hospitals. For high-bay facilities, we measure at scanner height in the aisles, not from the ceiling.

Where we survey

Surveys by building type

BuildingWhat we look for
OfficesConference room density and open-office capacity
Schools30 to 60 devices per classroom at once
HealthcareMedical equipment interference, roaming for mobile carts
WarehousesRacking multipath and dead zones at scanner height
Outdoor and campusCoverage between buildings and outdoor handoff

Standalone surveys

Survey only, or survey and install

We perform standalone surveys as an independent deliverable. The report and design are yours to use with any installer, and you're never obligated to hire us for the installation. If you do, the survey data drives the design directly and we validate the result afterward. See the Ekahau site survey page and wireless.

FAQ

Wireless site survey questions

How much does a wireless site survey cost?

A predictive survey for a single floor typically starts at $800 to $1,500. On-site surveys of multi-floor buildings run $1,500 to $4,000, depending on size and complexity. We quote a fixed price after reviewing floor plans.

How long does a survey take?

A walk survey of a 20,000 sq ft office typically takes 2 to 4 hours on site, with the report delivered in 3 to 5 business days.

What's the difference between passive and active surveys?

Passive surveys measure the RF environment without connecting. Active surveys connect a device and measure real throughput and roaming.

Do you survey for 6 GHz Wi-Fi 6E and Wi-Fi 7?

Yes. Our Ekahau equipment measures the 6 GHz band.

Can you survey for a project another company will install?

Yes. Standalone surveys are yours to use with any installer.

Do I need a survey for a warehouse?

Yes. Racking creates dead zones that floor-plan estimates miss, so warehouse surveys are measured at scanner height in the aisles.
