From my research I understand that the 802.11 wireless standards that operate in the 2.4Ghz range and use 11 channels, 3 of which are non overlapping. What I am having trouble grasping is things like Spread Spectrum types (FHSS and DSS) the 2.4 Ghz frequency band is said to be broken up into 70 1Mhz narrow channels that data flows through. So what is the difference between the two? Why does one 2.4Ghz Channel have 11 channels but at the same time have 70 Channels?
