WebDSSS is a related technique to FHSS. It also spreads a transmitted signal across a wide channel, but it does so all at once instead of in discrete bursts separated by hops. It can … Web1 de set. de 2013 · FHSS was a military development, as it was more difficult to eavesdrop a transmission changing frequencies all the time, but it was not designed with very high bandwith, transmitting speed or model aiplanes in mind. DSSS is faster as there is no timeloss for frequency changing, but easier to "jam" for the same reason (in theory) ". earl nottleman
