Signal Strength and SNR Heatmaps.
Signal strength and SNR heatmaps for all surveyed areas
Part of WiFi Surveys (Ekahau). Last reviewed October 2026.
Quick answer
What is Signal Strength and SNR Heatmaps?
Signal strength and SNR heatmaps are color-coded floor plan overlays showing received signal level (RSSI) and signal-to-noise ratio at every point in the surveyed area. Deploris produces them per floor, band, and requirement, so you can see exactly where coverage meets your targets and where it falls short.
WHAT THE WORK COVERS
What Signal Strength and SNR Heatmaps includes.
- 01Signal strength (RSSI) heatmaps per floor, split by 2.4 GHz, 5 GHz, and 6 GHz where those bands are in use
- 02Signal-to-noise ratio heatmaps built from measured noise floor, not an assumed value
- 03Secondary signal coverage and number-of-APs views to show roaming overlap and redundancy
- 04Requirement pass and fail overlays that color each area against the agreed minimum thresholds
- 05Heatmaps for the intended client device class, since a handheld scanner hears differently than a laptop
- 06Legend scales and thresholds printed on every sheet so readers can interpret colors without guessing
HOW WE DELIVER IT
How it is delivered.
- 1
Agree the thresholds
Before measuring, we write down the minimum RSSI and SNR you need per area and per use case, such as voice-grade coverage in clinical corridors or lower thresholds in storage.
- 2
Measure or model
Depending on scope, we collect on-site measurements with the survey kit, or generate predictions from the calibrated model, or both, then record which method produced each sheet.
- 3
Render by floor and band
We generate one heatmap sheet per floor, band, and metric, check each against the thresholds, and mark gaps, dead spots, and areas that were not accessible.
- 4
Walk you through the gaps
Your engagement manager reviews the findings with your team, separating real coverage problems from areas that are intentionally out of scope.
INPUTS AND OUTPUTS
What you provide and what you receive.
You provide
- Minimum signal and SNR targets, or the application requirements we should translate into targets
- A list of client device types in use, with notes on which are most coverage sensitive
- Site access to every area in scope, including locked rooms, plant rooms, and secure zones
- The list of SSIDs and bands you intend to run, including any 6 GHz plans
You receive
- Heatmap sheets for every surveyed floor, band, and metric, as PDF and as images
- A summary table of area coverage against each threshold
- A marked-up list of weak zones with plan coordinates for follow-up
- The underlying measurements in the Ekahau project file so the maps can be regenerated
WHEN IT FITS
When this is the right deliverable.
You need evidence that a new or existing wireless network reaches every required area at the signal level your applications demand.
Users report dead spots or dropped calls and you want a measured picture before spending money on more access points.
A contract, landlord, or internal standard requires a documented coverage map for each floor.
WHERE WE DELIVER
Delivered in 75+ metros across 11 countries.
Local, vetted engineers deliver this work on site across the United States and Western Europe, coordinated by one engagement manager.
