Question

What is the bandwidth of a microwave network and explain significance?

Answer 1

A microwave network may have a CARRIER frequency of 2,000 MegaHertz (which is also called 2 GigaHertz), but the information transmitted takes up more electromagnetic 'space' than just plain 2 GHz.  If the transmitted information actually uses frequencies from 1.95 GHz to 2.05 GHz, the bandwidth is the difference between those 2 frequencies:  2.05 - 1.95 GHz = 0.1 GHz which is equal to 100 MHz.

The band is 100 MHz wide.

The significance is, that all of that electromagnetic space is used up and no other carriers can operate in that band.  In this example 100 MHz is a LOT of space.  The operator of this carrier is either very wasteful, or he is transmitting 100s or even 1000s of channels of information inside that 100 MHz band.
