Modern 802.11 versions don‘t really use spread-spectrum anymore (neither FHSS, which is used by some versions of Bluetooth, nor DSSS, which was used in the original 802.11 and up to 802.11b), but rather OFDM on fixed carrier frequencies. Switching channels due to DFS is not "frequency hopping" in that sense – that would be many orders of magnitude faster. |
