4. 18 August 2003 - 3 Special Study Group on IMT-2000 and Beyond Revised forecasts with industry downturn “The continuing economic downturn and the catastrophic events of September 11th last year have given rise to concerns about the viability of mobile data services and in particular 3G. These concerns have been exacerbated by the slowdown in subscriber growth and the announcements by many operators of reduced capital expenditures. These developments have prompted The UMTS Forum to re-examine its 3G market forecasts published in August 2001. The results appear in the Forum’s Report No 18. The conclusion of this report is that there is no necessity to revise growth figures projected in the August 2001 report, which, in any event, were built on an assumption of slow adoption for the first five years of 3G availability.” Source: MobilleniuM, June 2002 ( http://www.umts-forum.org/mobilennium_online/2002.06/index.html )http://www.umts-forum.org/mobilennium_online/2002.06/index.html Special Study Group on IMT-2000 and Beyond
