Radio traffic disruption, not data manipulation. Like when your network hub stops working or someone is using a microwave in the next room, for example. Most zigbee devices are transmitting in the 2.4Ghz band, which makes them very susceptible to being drowned out by EMI.
- zevv 2y agoSure, so this clearly disrupts the transmission. But since there is strong encryption and authentication used in the Zigbee protocol, the chance of a mangled frame ending up at higher level in the protocol stack is approximately zero - anything messing up the frames will invalidate any hash so the receiver will discard these frames.
