A WiFi heat map turns your floor plan into a living signal portrait — every dead zone, weak corner and over-saturated channel revealed in colour. Before we mount a single access point, we already know where coverage will land, why it will hold, and how it will scale.
A WiFi heat map is a colour-coded visualisation of your wireless network laid over your physical space. Where most people see walls and rooms, we see signal strength (RSSI), signal-to-noise ratio (SNR), channel utilisation, throughput, roaming behaviour and interference — all rendered in real-time as warm and cool zones across your floor plan.
Heat mapping isn't guesswork. It is a precise, measurable engineering discipline that combines physical site walks, RF measurement, predictive modelling and validation testing. It answers, definitively, the question every business asks at some point: "Why doesn't the WiFi work properly here?"
At Quick Surf Network we run heat maps in three modes — predictive before installation, active during commissioning, and passive validation post-deployment — so you know exactly what coverage you are paying for, and exactly what coverage you are getting.
Behind every clean coverage report is a four-stage engineering workflow. We do not guess AP placement, we calculate it — then prove it.
We import your floor plan (CAD, PDF or image) into Ekahau, NetSpot or TamoGraph. Every wall, glass partition, lift shaft and concrete column is mapped with its real RF attenuation value — drywall is not concrete, and concrete is not glass.
The software simulates AP placement, transmit power, antenna patterns and frequency bands across 2.4 GHz, 5 GHz and 6 GHz (WiFi 6E / 7). We test capacity per client, co-channel interference and roaming overlap before a single cable is pulled.
An engineer walks the site with calibrated WiFi adapters and a GPS / floorplan tracker, sampling RSSI, SNR, retry rates and throughput at hundreds of points. Real measurements replace assumptions — drywall water content, furniture density and human bodies all alter RF.
After install we run a passive survey to confirm SLA targets — typically -65 dBm primary coverage, -67 dBm for voice, 25 dB SNR minimum. You receive a deliverable PDF heat map, channel plan, AP inventory and recommended remediation list.
A WiFi installation without a heat map is an expensive bet. A WiFi installation with a heat map is an engineered outcome. The difference shows up on day one — and every day after.
Predictive heat mapping reveals coverage gaps before they exist. No more "the signal is fine in the lobby but drops in the boardroom" surprises after the contractors have left.
Most networks are over-deployed in some areas and under-deployed in others. A proper survey trims unnecessary APs and adds them where they actually move the needle — protecting capex and opex.
Density is the new coverage. Heat mapping forecasts client load — 80 students in a classroom, 200 attendees in a hall — so the network is sized for tomorrow's IoT, AR and 4K streaming, not yesterday's email.
Co-channel interference and rogue APs from neighbours, microwaves, baby monitors and Bluetooth gear silently kill performance. A spectrum-aware survey identifies the noise floor and engineers around it.
The deliverable PDF heat map is your acceptance document. Vendors can no longer claim "it works fine on our laptop" — every coverage commitment is measured, signed and dated.
VoIP, Microsoft Teams calls and warehouse barcode guns demand seamless 802.11k/v/r roaming. Heat mapping engineers the AP overlap that keeps a call alive as you walk from desk to lift to car park.
If any of these scenarios sound familiar, a heat map will pay for itself before the next quarter closes.
Every space has a different RF personality. Here is what a heat map delivers across the four environments QSN works in most often.
We publish one in full. An independent audit of an existing third-party villa installation found 32 access points fitted but only 9–12 reaching usable signal strength on any floor, 14 rooms below the design threshold, half the 2.4 GHz radios sharing a single channel, and roughly 110 devices — cameras included — on one flat subnet with no VLAN boundaries. More access points is not more coverage. This is the difference between a network that was installed and a network that was designed.
Send us your floor plan. We will return a predictive heat map, AP plan and budget — typically within 5 working days.
