Spectrum analyzers are necessary tools for installing wide area wireless networks (i.e. WISP) and can even be used by the typical consumer dealing with interference from mobile phones or microwaves. The spectrum analyzer basically gives you information about the wireless spectrum envrionment, to help you make choices that maximize coverage and minimize interference. Up until now, good spectrum analyzer’s have only been available for thousand’s of dollars. But MetaGeek has released a solid USB spectrum analyzer that will meet most people’s needs for only $99. Now all those wireless hacks can do things right!
