The microwave spectrum is usually defined as a range of frequencies ranging from 1 GHz to over 100 GHz. This range has been divided into a number of frequency bands, each represented by a letter. A frequency band is simply the range or interval of radio frequencies used to transmit a signal over a telecom network.
Understanding the Context
All bands -- of which there are many -- are identified by their lower and upper limits. Radio frequencies are often grouped in ranges called bands. There are numerous ways frequency bands have been designated. The International Telecommunications Union designates bands as listed in the table below.

Key Insights
There are also other approaches to designating frequency bands. A frequency band can be described as a collection of frequencies ranging from a lower frequency to a higher frequency. The different frequency bands of the electromagnetic spectrum are allocated for various applications. A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. Radio Frequency (RF) is the lowest portion of the electromagnetic spectrum and is familiar as a medium of analog and modern digital wireless communication systems.
