  1. Recent Activities for IMT in Japan

  2. Trends of Mobile Communication Systems in Japan • The number of Mobile Phone subscribers including PHS in Japan : 110.64 million (as of the end of January 2009) • Rapid sift from 2G to 3G (IMT-2000) : 91.3 % 3G penetration • Active studies on IMT (IMT-2000 and IMT-Advanced) • Report by Telecommunications Council to Ministry of Internal Affairs and Communications (MIC) on technical conditions for 3.9G including enhanced 3.5G in December 2008 • Preparing to submit candidate IMT-Advanced radio interface technology proposal to ITU-R by October 2009 • 2.5GHz Band Mobile BWA (Broadband Wireless Access) systems licensed to 2 operators based on mobile WiMAX(IEEE802.16e) and XGP (Next Generation PHS) technologies in Dec.2007 • Preparing to start mobile BWA services this spring

  3. Introduction of 3.9G system in Japan (1/3) • As both leisure and commercial applications increase in sophistication and diversity, data communications using mobile phones, including Internet access and video transmission, are on the rise. • In response to growing expectations for the introduction of a mobile communications system that is faster, has a greater capacity and is more convenient, the standardization of the 3.9 G mobile communications systems has been completed towards the global deployment. • In Japan, efforts to commercialize such a system by around 2010 have been accelerated.

  4. Introduction of 3.9G system in Japan (2/3) • In 2008, Telecommunications Council under MIC has conducted the following studies; • Study on technical measures for the enhancement of the third-generation mobile communications system • Study on conditions to coexist with other systems for the introduction of the enhanced third-generation mobile communications system • Spectrum bands of 2GHz, 800MHz, 1.5GHz and 1.7GHz considered • Candidate Enhanced Systems (FDD) studied by the council including 3.5G • LTE, UMB and Mobile WiMAX for 3.9G system • Note: Although the sharing studies regarding WiMAX have been done, the technical conditions of it are not included in the report of Telecommunications Council. • HSPA Evolution and DC-HSDPA for enhanced 3.5G system
