RF Jamming. Radio frequency interference, or RFI, is something that we've all encountered at one point in our lives, whether you've heard the buzzing noise in your computer speakers moments before your cell phone began to ring or the static on a distant radio station.t is much more likely that a malicious jammer would blast an area with interference in the entire 802.11a/b/g/n (2.4 GHz and 5.2 GHz unlicensed bands.) Any change in frequency by the access point would be useless and all connected clients would be promptly disassociated.
