I am confused about the meaning of the term 'Bandwidth' in a wireless transmission environment. The two most common definitions I could find are:
- difference between the upper and lower frequencies in a continuous band of frequencies
- the maximum rate of information transfer (bps) across a given path
How do I reconcile these (assuming they are reconcilable)? In other words, why does the difference between the upper and lower frequencies in a frequency band equal the maximum rate of information transfer across the path transmitted? Can someone kindly explain the connection in a clear, visual way if possible?
