Spectrum analyzers--what's in your wireless landscape?

With all the frequencies home gadgets emit, it's hard to identify what may be wreaking havoc on your wireless network. A landscape of wireless game controllers, Bluetooth headsets, microwave ovens and other frequencies can interfere with a Wi-Fi connection. But a spectrum analyzer can detect frequencies from objects that might be affecting Wi-Fi. A sensitive wide band receiver, a spectrum analyzer converts higher frequencies to measurable quantities. It displays received signal strength against frequency so you can see what is getting in the way between you and the Internet.

Many spectrum analyzer products are out in the market. The compact Wi-Spy from Metageek is a 2.4 GHz spectrum analyzer that harnesses the processing power of the computer that it's connected to.

AirMagnet's spectrum analyzer identifies, classifies and finds sources of interferences that impact the performance of Wi-Fi networks. With a user-friendly interface, the system automatically identifies the specific types of devices causing interference and tracks them to their physical location, enabling network managers to resolve issues quickly and easily.
