802.11n uses a wireless-networking standard that uses multiple antennas to increase data rates, MIMO (multiple-input and multiple-output).

802.11n: has a throughput of 600 Mbit/s using either the 2.4 or 5 GHz frequency band.

802.11g suffers from the same interference as 802.11b in the already crowded 2.4 GHz range. 802.11g hardware is fully backward compatible with the previous 802.11 specification, 802.11b.

802.11g: has a throughput of 54 Mbit/s using the 2.4 GHz band.

The following three are by far the most common: It should be able to pick up all signals on the 2.4 GHz and 5 GHz frequencies and identify all 802.11 networks.Ĩ02.11 technology is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area networks, and there are several different 802.11 protocols used by modern wireless routers and devices today. Which WiFi Spectrum Analyzer Should I Use?Ī good WiFi spectrum analyzer should meet certain criteria. 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. Without WiFi spectrum analyzers, locating the exact source of interference would be unreasonably difficult. That includes microwave ovens, Bluetooth devices, car alarms, CCTV wireless surveillance video cameras, and cordless phones. Because of the steep rise of mobile and IoT (Internet of Things), the WiFi frequency spectrum has never been more crowded.īut 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.

Ideally, no two WiFi networks should run on the same channel, but this is seldom possible in practice. Each of these two frequency bands is divided into multiple channels, which provide a degree of separation of individual networks.

WiFi networks are broadcasted either on the 2.4 or the 5 GHz frequency band. A WiFi spectrum analysis is typically performed to find interference that negatively impacts wireless performance and to eliminate it. A WiFi spectrum analysis is the process of measuring the WiFi signal in a certain area and determining its strength.
