Optimal frequency-hopping sequence (FHS) design lies at the heart of modern spread-spectrum and multiple-access communication systems. By rapidly switching transmission frequencies according to a ...

New hardware could lead to wireless devices that identify and exploit unused transmission frequencies, using radio spectrum much more efficiently. New hardware could lead to wireless devices that ...

Harris has introduced new capabilities in electronic counter-countermeasures (ECCM) that will enhance the information security and reliability of tactical communications for international armed forces ...

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 ...

Researchers at MIT have found a way to stump hackers who are trying to snag data from wireless signals. They've created a transmitter that moves data packets between different radio frequencies ...

We’ve seen a lot of hacks with the nRF24l01+ 2.4 GHz radio modules. The tiny chips pack a lot of bang for the buck. Since the radios can switch frequencies relatively quickly, [Shubham Paul] decided ...

The Lancehead's built-in frequency-hopping technology could make it an attractive choice for gamers previously worried about the accuracy of wireless mice. I’m a managing editor at PCMag.com focused ...
