IMT-Advanced Technical Requirements are nearly complete –Spectrum –requested in WRC07 Agenda Item 1.4 (2007-10-22 - 2007-11-16) –Technical (radio) requirements only other unfinished work item ITU-R Circular Letter soliciting solutions due out March 2008 Commercial deployment of IMT-Advanced expected around 2012 IEEE 802 submitted suggestions on IMT Tech to WP8F (mid May 2007) –Contributions included from.11,.16,.18,.19,.20,.21 –WP8F review in Kyoto (end of May) IEEE 802 held additional teleconferences between Sep-Nov 2007 and submitted additional suggestions on IMT Tech to WG18 on 2007-10-29.

M.1457 –Defines ITM-2000 “family” of technologies –That family now includes 802.16e RA adopted new naming convention for 3G/4G mobile –The name “IMT” is an umbrella that includes IMT-2000 – 3G (technologies contained in M.1457) IMT-Advanced – 4G (technology/technologies not yet defined) – Spectrum identified by a WRC will be for IMT Can be used by all IMT technologies
