What Is WiFi Spectrum Analysis?
A WiFi spectrum analysis is the process of measuring the WiFi signal in a certain area and determining its strength. A WiFi spectrum analysis is typically performed to find interference that negatively impacts wireless performance and to eliminate it.
WiFi networks are broadcasted either on the 2.4 or the 5 GHz frequency band. Each of these two frequency bands is divided into multiple channels, which provide a degree of separation of individual networks.
Ideally, no two WiFi networks should run on the same channel, but this is seldom possible in practice. Because of the steep rise of mobile and IoT (Internet of Things), the WiFi frequency spectrum has never been more crowded.
But it’s not just WiFi networks themselves that cause interference and corrupt other WiFi signals, most common electronic devices can create interference and noise as well. That includes microwave ovens, Bluetooth devices, car alarms, CCTV wireless surveillance video cameras, and cordless phones.
Without WiFi spectrum analyzers, locating the exact source of interference would be unreasonably difficult. Fortunately, there are many excellent WiFi spectrum analyzer software solutions available today, and many of them, including NetSpot, are so easy to use that even home users without any IT training can use them to optimize their home networks and say goodbye to slowdowns and connection drops.
