## Abstract

A system, method, and computer readable storage device are provided for collecting data associated with a WiFi signal profile of an area of interest (AOI), analyzing the collected data, and generating a dataset from the data representative of the signal profile. The dataset includes value information and location information, wherein value information include signal data that are to be displayed in a visual representation. The dataset includes values of measured WiFi signal strengths, and in some examples the values are weighted based on one or a combination of device data, interference data, and business-related data. This can enable generation and display of a visual representation that includes a representation of signal strength values based on assessed signal strengths needed to support particular services on particular user devices. The visual representation can be a heatmap that shows color-coded variations in WiFi signal values associated with locations or devices in the AOI.
