WiFi site surveys & heat maps

Predictive, passive and active surveys that prove coverage before you spend on hardware — and prove it again after installation, with heat maps and a written report you own.

WiFi Site Surveys & Heat Maps — Victel installation
The problem

Stop buying access points and hoping

The most expensive wireless mistake is not buying the wrong access point — it is buying the right one and putting it in the wrong place. A survey costs a fraction of a deployment and routinely changes both the hardware count and the design.

We survey before design, and we survey again after installation to verify what we promised. Both sets of data belong to you, which also means you have an objective baseline the next time somebody claims 'the WiFi is slow'.

  • Know the AP count before you commit budget
  • See coverage, interference and roaming behaviour on a floor plan
  • Objective evidence instead of arguments about 'slow WiFi'
  • Post-install verification that the design was delivered

Why Victel

Four survey types, four different questions

A predictive survey models your building from floor plans and construction materials — it answers 'roughly what will this take?' before anyone visits. A passive survey walks the real space listening, and answers 'what is actually happening in here today?'

An active survey connects to the network and measures real throughput, retries and roaming — it answers 'will it actually work for my users?'. Spectrum analysis looks below WiFi entirely, at the microwaves, cameras and cordless gear quietly destroying your airtime.

  • Predictive modelling from floor plans and materials
  • Passive walkthrough surveys with heat maps
  • Active throughput, retry and roaming validation
  • Spectrum analysis for non-WiFi interference
  • Pre-deployment AP-on-a-stick validation
  • Post-installation verification and sign-off report
How it works

Our three-step process

Documented, predictable and phased so your operation keeps running while we work.

1

Model the building

We build a predictive model from your floor plans, marking construction materials, ceiling heights and obstructions.

Get started
2

Walk and measure

On site we run passive, active and spectrum captures — and where the design is uncertain, mount a live AP and test the real position.

Get started
3

Report and recommend

You receive heat maps, interference findings, an AP placement plan and a written recommendation you can quote against anywhere.

Interference findingsCo-channel and adjacent-channel contention plus non-WiFi sources identified
AP placement planExact mounting positions, models, mounting heights and antenna choices
Channel & power planA concrete channel and transmit-power scheme, not vendor defaults
Capacity analysisUsers and devices per area against realistic per-AP capacity

FAQ

Questions about wifi site surveys & heat maps

A predictive survey takes a few hours once we have usable floor plans. An on-site passive and active survey typically runs half a day for a standard office and a full day or more for a large warehouse or multi-floor building.

Below roughly 5,000 sq ft of simple drywall construction, a predictive model plus an experienced walkthrough is usually enough, and we will say so rather than sell you a full survey. Anything with concrete, steel, racking, glass partitions or multiple floors genuinely needs the measurements.

Yes, entirely. The heat maps, findings and placement plan are yours, and you are free to quote the work elsewhere. We would rather earn the installation than trap you with the data.

Frequently. Rescue surveys are common — the deliverable is a remediation list ordered by impact, and it often shows that configuration changes and a few relocations fix the complaint without new hardware.

We temporarily mount a live access point at a proposed position, on battery, and measure real-world coverage from it. It is the only way to be certain about difficult areas — cold storage, mezzanines, high-racking aisles — before committing to a design.
