The C band is a name given to certain portions of the electromagnetic spectrum, including wavelengths of microwaves that are used for long-distance radio telecommunications. The IEEE C-band (4 GHz to 8 GHz) - and its slight variations - contains frequency ranges that are used for many satellite communications transmissions, some Wi-Fi devices, some cordless telephones, and some weather radar systems. For satellite communications, the microwave frequencies of the C-band perform better under adverse weather conditions in comparison with K_u band (11.2 GHz to 14.5 GHz) microwave frequencies, which are used by another large set of communication satellites. The adverse weather conditions, collectively referred to as rain fade, all have to do with moisture in the air, including rain and snow.

The NATO C-band is that portion of the radio spectrum between 500 megahertz (MHz) and 1000 MHz, but this terminology is rarely used in the NATO members that are located in North America.

The IEEE C-band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz), but this definition is the one that is followed by radar manufacturers and users, but not necessarily by microwave radio telecommunications users.

Switch was an R&B/funk band that found fame recording for the Gordy label in the late 1970s, releasing hit songs such as "There'll Never Be", "I Call Your Name" and "The Best Beat in Town". Switch influenced bands such as DeBarge, which featured the siblings of Switch band members Bobby and Tommy DeBarge.

The group, formed in Mansfield, Ohio in 1974 under the name First Class, featured brothers Tommy and Bobby DeBarge and Greg Williams from Grand Rapids, Michigan, along with Akron, Ohio natives Phillip Ingram (brother of James Ingram), Eddie Fluellen and Jody Sims. They joined Barry White's group, White Heat, as background musicians and were let go shortly thereafter when White Heat experienced financial troubles.

Eventually changing their name to Switch due to their ability to switch to different instruments during a song, the group got the attention of Jermaine Jackson, former member of The Jackson 5 and husband of Hazel Gordy (daughter of Motown Chief Berry Gordy, Jr.), who heard the group's demo tape. Within days, the group was signed to the Motown Records subsidiary label, Gordy. They recorded and released their self titled debut album in 1978, which featured their first Top 10 R&B hit single, entitled "There'll Never Be".
