Whereas during Wi-Fi site surveys it is acceptable to fairly quickly walk around the facility taking measurements, spectrum analysis is something done in selected locations only, spending more time (for example one minute) in a given location. It is important to note that taking measurements using a spectrum analyzer requires a method different from Wi-Fi site surveys. Troubleshooting: The most common purpose for a spectrum analyzer is troubleshooting - Whenever Wi-Fi issues arise that are not solvable with a Wi-Fi site survey, Ekahau recommends using Ekahau Spectrum Analyzer - Typically, collecting a minute or two of data with a spectrum analyzer will reveal the underlying issueįirstly, you will need to connect the Ekahau Sidekick (or other supported spectrum analyzer) to your computer.Network verification: A Wi-Fi site survey done with Ekahau Pro is always highly recommended when verifying the network - This is typically done before the network production use starts, and periodically (for example, every month) - During the verification check, you may choose to perform spectrum analysis spot-checks at selected locations to ensure that there are no significant interference sources present.Network planning: Find out the interference sources before you deploy any access points by making spot-checks with the spectrum analyzer around the facility - Detecting the interference issues in advance may affect the access point placement and configuration.For Ekahau Pro users, using spectrum analyzer is recommended in the following scenarios: One or more channels completely unusable momentarily or permanentlyįor the reasons mentioned above, it is highly recommended to use Ekahau Sidekick or other spectrum analyzers when deploying or troubleshooting a wireless network.Lower than expected network performance.Occasional, momentary connectivity cut-offs. Connectivity issues caused by non-Wi-Fi interference may include: In cases where the interference is caused by a non-Wi-Fi device, the interference issues may not be detected by the Wi-Fi adapter. Spectrum activity on Wi-Fi channels 1-3Įkahau Pro uses the Wi-Fi adapters to take signal measurements. Some examples of non-Wi-Fi devices that may operate on Wi-Fi frequencies are: This means that these frequency bands are not limited to Wi-Fi - devices other than Wi-Fi also operate on the same frequencies. Wi-Fi devices operate on license-free frequency bands.
