MIT researchers have developed a novel transmitter that frequency hops for each individual 1 or 0 bit of a data packet – so once per microsecond for 1Mbit/s, “which is fast enough to thwart even the quickest hackers”, according to MIT. The system can protect against selective jamming. For example, explained the University, Bluetooth LE ...
