Intuition on Network Spectrum and Bandwidth

Source:  A Survey of 5G Network: Architecture and Emerging Technologies

"The process of building a network environment includes two parts: consider the spectrum and then the bandwidth. Using cars on the highway as an analogy, the highway is like a spectrum, lanes are like the channels, and whether the car should be on the highway is determined based on the existence of holes, interference, or other factors of the channel. The lane to be used and when to switch lanes can also be determined.

In a network environment, such behavior results from direct contact with the radio section.
This study defines this as the SDR Layer, and the main work is the perception of the available spectrum and bandwidth." [1]
