The X band is a segment of the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of X band is rather indefinitely set at approximately 7.0 to 11.2 gigahertz (GHz). In radar engineering, the frequency range is specified by the IEEE at 8.0 to 12.0 GHz.
The term "X-band" is also used informally and inaccurately to refer to the extended AM broadcast band, where the "X" stands for "extended".

Famous quotes containing the word band:
“What passes for identity in America is a series of myths about one’s heroic ancestors. It’s astounding to me, for example, that so many people really seem to believe that the country was founded by a band of heroes who wanted to be free. That happens not to be true. What happened was that some people left Europe because they couldn’t stay there any longer and had to go someplace else to make it. They were hungry, they were poor, they were convicts.”
—James Baldwin (1924–1987)
