The bandwidth of a signal depends on the amount of information contained in it and the quality of it. You can increase a network’s bandwidth all you want, but all you’ll end up doing is increasing the amount of data that can be sent at one time, not increasing the transmission speed of said data. What is the difference between cloud computing and virtualization? Transmission capacity of a communication channels « The bandwidth of a channel is the frequency range over which it can transmit a signal with reasonable fidelity. Imagine that each side of the transmission has a modem with a different data rate. So, the higher the capacity of the communication link, or pipe, the more data can flow through it per second. What are different types of communication media? #    Big Data and 5G: Where Does This Intersection Lead?
