Wireless Site Surveys & Wi-Fi Heat Mapping

Three kinds of survey, and when each one matters

Which survey you need depends on where the project is. Most jobs use one; a large or difficult building uses all three.

• Predictive design — modeled from drawings during design or pre-construction, before cable is pulled
• Validation survey — measured on site in the actual building, walls and finishes included
• Post-install verification — confirms real coverage and roaming after access points are mounted
• Troubleshooting survey — measures an existing network that is already underperforming

Coverage and capacity are two different problems

A building can have a signal everywhere and still have Wi-Fi that fails. Coverage is whether the radio reaches; capacity is whether it can carry the number of devices in the room. A full dining room, a training room, or a warehouse at shift change are capacity problems, and no amount of signal strength fixes them. We survey for both and size the access point count to the busier of the two.

• Coverage: signal reach, overlap for roaming, edge-of-cell performance
• Capacity: device count per room at the busiest hour, not the average
• Dense spaces: dining rooms, conference and training rooms, waiting areas
• Roaming: enough overlap that handhelds and phones hand off cleanly

Buildings that need a survey most

Some spaces punish a guessed design harder than others. If your building is on this list, the survey pays for itself the first time you avoid an extra drop through finished drywall.

• Warehouses and high-bay spaces where ceiling height and racking drive AP count
• Cold storage, freezers, and metal-heavy industrial areas
• Restaurants with kitchens, coolers, and a full dining room at peak
• Older buildings with plaster, masonry, or foil-backed insulation
• Multi-tenant offices sharing spectrum with neighbors
• Anywhere handheld scanners or VoIP phones have to roam without dropping

Interference and channel planning

Half of commercial Wi-Fi complaints are interference, not coverage. Neighboring tenants, existing equipment, and badly configured access points all fight for the same channels. A survey looks at what else is in the air before setting channel and power, and it's the reason two identical buildings can need different configurations.

• What else is broadcasting in your space and next door
• Channel and transmit power plan rather than everything on auto at full power
• Band planning across 2.4, 5, and 6 GHz where hardware supports it
• Non-Wi-Fi interference sources found during the walk

What you get

The survey is a document you can build from, quote from, or hand to a client — not a verbal opinion at the end of a walkthrough.

• Coverage heat maps showing what the design delivers
• Access point count with specific mounting locations
• PoE drop schedule the cabling crew or electrician can work from
• Channel, band, and power recommendations
• Notes on problem areas and what it would take to solve them

For IT and MSP partners

Hand us the survey and take it off your plate entirely. We walk the site, measure it, and come back with documentation written for your client to read — priced so there's margin in it for you. You keep the network, the configuration, and the relationship. We'll sign a non-solicitation agreement naming your clients before the first visit if you'd like that in writing.

• White-label survey documentation under your project name
• Priced for markup or pass-through billing through your PSA
• We install the AP platform you standardize on — the survey doesn't change
• Survey can stand alone or roll into an install we quote underneath you

How it runs

We confirm what the space has to support, walk and measure the building, then deliver the heat maps, AP locations, and drop schedule. If the project moves forward, the survey feeds straight into the cabling and install quote so nothing gets re-measured.
