Software Defined Radio
Everything on the RF spectrum outside WiFi: key fobs, tire-pressure sensors, ADS-B aircraft transponders, POCSAG pagers, and general-purpose signal capture/analysis. Its own category rather than folded into Wireless Attacks — that category is WiFi-specific, and the 16 tools here would have swamped it.

Two webapp shortcuts pair with this category:
KiwiSDR Public Receivers (browse public web-SDRs, works with supersdr
above) and SIGIDWiki, a signal-identification database for waveforms you
capture but don’t recognize.
