There are two types of surveys that you can conduct with TamoGraph: passive and active. During a passive survey, the application collects the most comprehensive data on the RF environment: information on access points and their characteristics, signal strength, noise level, interference, etc. This is the default and most important survey type that we recommend to conduct in every case. It is called passive because during this type of survey, the application passively listens for packets and does not attempt to connect to WLANs. However, to provide more insight into the real-world performance of your WLAN, TamoGraph can also perform active surveys, during which your Wi-Fi adapter connects to the wireless network(s) of your choice to measure actual throughput rates and a few other metrics. Please refer to the Understanding Survey Types: Passive vs. Active chapter for more information on this topic.
