WiFi Heat Map – Network Analyzer and Signal Meter.Keep in mind though that for a large scale enterprise site survey you will need professional gear (wifi hardware with specialized interface cards etc) so that you can get the best results. Some of them are even free so they can benefit a person who wants something simple for smaller environments. I have done my research and curated the top heat map tools in the market in the list below. Many professionals responsible for installing and maintaining WiFi networks will find a lot of value to WiFi heat map software in order to implement an environment with the best wireless coverage and performance possible. WiFi heat map software can create an accurate map of signal strength during a site survey, producing a graphical representation of hot, cold, and dead areas. However, it’s not uncommon for signal strength to degrade due to a variety of factors, including distance from the access point, obstacles, competing WiFi signals, and appliances. In fact, it’s the de facto standard used to create wireless networks in homes, businesses, public spaces etc. WiFi is an incredibly useful communication protocol that is widely used.
