One of the technologies meeting the IMT-2000 requirements for a third generation (3G) global wireless communications system is cdma2000®, also known as IS-20001. The Third-Generation Partnership Project 2 (3GPP2) wrote the specification for this wideband code division multiple access (CDMA) system as a derivative of the IS-95-B CDMA system, also known as cdmaOne. The 3GPP2 organizational partners are the Japanese Association of Radio Industries and Businesses (ARIB), Telecommunication Technology Committee (TTC), Telecommunications Industries Association (TIA), and Korean Telecommunications Technology Association (TTA).
