In this review we look at five mobile survey apps: iBwave Wi-Fi Mobile, iMapper WiFi Pro, WiFi Analyzer and Surveyor from ManageEngine, Wi-Fi Visualizer from ITO Akihiro, and WiTuners Mobile.They range from free/cheap options for surveying small office networks to those with an enterprise price tag designed to handle larger networks. (And in case you’re wondering why we're not discussing iOS apps, it’s because Apple won’t allow developers access to the Wi-Fi data, thus there can’t be any legit Wi-Fi surveying apps without jailbreaking the device.) However, if you don’t require all the bells and whistles, using an app on an Android-based smartphone or tablet can lighten your load. Most Windows-based Wi-Fi surveying tools offer more features and functionality than Android-based tools provide, such as detecting noise levels and providing more heatmap visualizations. They allow you to load your floor plan map, walk the building to take measurements and then give you heatmaps of the signals and other data.

A simple Wi-Fi stumbler is great for quickly checking signal levels, but a map-based surveying tool helps you visualize the coverage, interference and performance much more easily.

Visualizing how the signals move about the area is difficult without the right tools. Different types of walls, materials and objects can impact the Wi-Fi signal in varying ways. Wi-Fi networks have many variables and points of frustration.
