A 2.4GHz Spectrum Analyser

A week or two ago something was causing interference to my wifi signal so I lost my internet connection on the laptop, tablet and the iPhone for almost an hour.

Although the WiFi Analyzer on the tablet showed nothing untoward, that App will only detect genuine WiFi signals. Unfortunately, there’s a myriad of other devices which use the same 2.4GHz band which don’t show up but which can block the WiFi signals.

I’ve made a start on cobbling together a simple spectrum analyser for the 2.4GHz band which will detect any source of interference. Although it won’t actually cure the problem, it should at least give some peace of mind that it’s not my equipment that’s starting to act up.

I’ll post full details on my main site once it’s a viable, build-able project.
