I'm newbie in wireless communication and have many questions with spread spectrum. I've learned that spread spectrum method for transmission RF signal is less susceptible to intentional jamming or unintentional interference from outside sources and multipath interference problem. Because it uses range of frequencies that it has.
I don't understand this point. How does spread spectrum technologies that use spread spectrum method send its data by using range of frequencies?
Given that, There is one Wi-Fi device that uses dsss technology to transmit its data with channel 1 that has 22 MHz wide from 2.401 GHz to 2.422 GHz. How does this device transmit its data that consist of 1.000 bits by using this 22 MHz wide?
Does this device transmit its data as a beginning 2.401 GHz at a given time, and after some time 2.402 GHz and after some time 2.403 until 2.422 GHz? Does it use range of frequencies like that?
