The beauty of spread-spectrum is that you can have multiple signals co-existing in the same part of the band without any significant interference. This is because of temporal dilution -- the fact that a transmitter can only send on exactly one frequency at any given instant in time.
So, the more of the band that a signal uses, the less chance there is that it will actually be sending any exact frequency at any given time.
This is how "spreading" (or PN) codes work with spread spectrum. They are a bit like "microhopping" within the channel that the system is currently using.
Perhaps I should do a video to show exactly how that works and therefore, how many SS systems can use what appears to be exactly the same range of frequencies at the same time without interfering with each other.
Any votes for that vid?
