SNR/Wi-Fi signal strength map

Generate a wifi SNR map to calculate the wireless signal quality

A wifi snr map, or signal strength  map, is quite similar to a Wi-Fi coverage map (heatmap), but this type includes Wi-Fi signal to noise ratio when graphically displayed.

Wi-Fi SNR data collection and map generation features are now included in the latest version of Acrylic Wi-Fi Heatmaps wireless coverage analysis software.

Signal to noise ratio (SNR or S/N) is defined as the proportion between the propagated signal strength and the interfering noise power. SNR is measured in decibels.

How to obtain the measurements

This Wi-Fi signal strength map is generated during a passive site survey by measuring Wi-Fi signal strength and Wi-Fi interferences to help identify well performing areas with stronger Wi-Fi signal.

SNR signal level is calculated as the difference between signal strength and noise (SNR stands for ‘Signal to Noise Rate’). These values are required to generate Wi-Fi signal strength maps.

The higher the value, the better the user experience, transmission speed, and Wi-Fi communication stability.

The generation of this type of map requires measurements using Acrylic Wi-Fi Sniffer or an Airpcap NX card set on monitor mode.

Wi-Fi Signal Strength Map Color Scheme

Wi-Fi heatmaps, such as wifi snr map, are represented using color schemes that can be configured for better visual results.

There are 11 color schemes available for signal strength representation.

A Wi-Fi coverage report generated in an Acrylic Wi-Fi Heatmaps Wi-Fi site survey comprises all these maps, including Wi-Fi signal strength map by default, along with many others.

Also included is the automatic WiFi signal quality map, and many more.
