nearfield


Also found in: Dictionary, Thesaurus, Wikipedia.

nearfield

The closest distance from a source to its destination. The term generally refers to wireless communications as well as studio monitors (speakers) designed for close listening. Contrast with "farfield," the farthest distance and "midfield;" in between. See NFC and electroceutical.
