A conventional 802.11-based radio, or more precisely the information that radio's driver will give you, is probably not going to reveal much more detail about the band, besides the names of any broadcasting APs in range and their respective signal strengths. Raw interference can be invisible to radios (besides the conspicuous absence of signal quality that results).
Ubiquiti sells a cheap USB dongle spectrum analyzer with the scan results displayed via Java app (so it is somewhat platform independent). I've used this analyzer myself several times, and it works decently. http://www.ubnt.com/airview On Thu, Apr 4, 2013 at 8:26 PM, cmsv <[email protected]> wrote: > I have been having some very strange behaviour in my wireless mesh which > i have noticed that may very well related to wireless interferences and > have been thinking about getting a spectrum analyzer to see what exactly > is going on. > > However these tools are still quite expensive and even tho i have been > searching for a homemade solution i thought asking here if anyone has a > found a inexpensive DIY solution or can recommend something equivalent. > > I have heard that it may be possible to do one using a regular usb > wireless adaptor but have not found anything to back up that rumour. > > Maybe someone can shed some light into my quest. > > > > > > > > -- > Redes mesh wirelesspt > > http://wirelesspt.net > Mesh: http://tinyurl.com/wirelesspt > Chave publica PGP/SSH: http://wirelesspt.net/arquivos/pk > Email assinado digitalmente pelo emissor assegurando autenticidade > > > _______________________________________________ > openwrt-users mailing list > [email protected] > https://lists.openwrt.org/mailman/listinfo/openwrt-users > > -- Ben West http://gowasabi.net [email protected] 314-246-9434
