¿µ¹®³»¿ë¿ä¾à At May 2000, ITU-R published the 3rd Generation Mobile Communication. Since then, ¡®Recommendation ITU-R M.1457¡¯ is regularly revised within 1 ~ 2 years to include its evolved technology. M.1457 included 6 technologies as shown in below.
¨ç IMT-2000 CDMA Direct Spread : operated as asynchronous mode and evolved to WCDMA/HSDPA/LTE FDD (Standardization body: 3GPP)
¨è IMT-2000 CDMA Multi Carrier : operated as synchronous mode and evolved to CDMA2000/CDMA2000-1x EVDO (Standardization body: 3GPP2)
¨é IMT-2000 CDMA TDD : operated as time division multiplexing and evolved to TD-SCDMA/LTE TDD (Standardization body: 3GPP)
¨ê IMT-2000 TDMA Single Carrier : developed by United State(TIA), and also known as EDGE
¨ë IMT-2000 FDMA/TDMA : Cordless telephone technology which was developed by ETSI, and also known as DECT
¨ì IMT-2000 OFDMA TDD WMAN : Korea was actively driven the development of its technology, and also known as Mobile-WiMAX, WiBro.

Korea has been actively participated in specification development of IMT-2000 CDMA Direct Spread, CDMA Multi Carrier, OFDMA TDD WMAN. This standard adopt the 12th revised version of M.1457 which was published at Jan. 2015. The 12th revised version of M.1457 added the 3GPP Release 11 technical specifications, etc.
