Performing Spectrum Analysis Surveys

Spectrum data can be collected either simultaneously with passive surveys or in spectrum-only mode (you will be prompted to select one of these two options in the survey type selection dialog.) The survey procedure is very similar to the one that you follow when you perform standard passive surveys. It is described in detail in the Data Collection chapter. To collect spectrum data during a passive survey, simply plug Wi-Spy into a USB port of your computer before you begin the survey. However, there are a few peculiarities that you should keep in mind:

· Spectrum data collection cannot be performed simultaneously with active surveys. During active surveys, spectrum data might be distorted due to the proximity of the Wi-Fi adapter that sends and receives large amounts of data. Therefore, spectrum data collection is disabled when active or simultaneous passive + active surveys are performed.
· The data collection style for a spectrum survey is typically different from the style used for standard Wi-Fi surveys. Specifically, when performing spectrum surveys, the surveyor should spend more time in each survey point before moving to the next one. However, simultaneous Wi-Fi and spectrum data collection might give the surveyor valuable information. We recommend using the point-by-point mode, as described in the Data Collection chapter, because in that mode, the spectrum analyzer has more time to collect data than it has in continuous mode. If you prefer to collect spectrum data in a traditional way, i.e., spend 30 seconds or a minute in a given location or zoom into a specific frequency range, you can do that using Chanalyzer.
