3G technology was developed through research and standardization efforts in the 1980s and 1990s. It allows for faster data transfer speeds between 400 MHz and 3 GHz. 3G brought improved internet access to mobile phones through technologies like i-mode and FOMA. It allows services like video calling and faster downloading. While early 3G adoption was led by countries like Italy and the UK, the technology has since expanded globally with over 475 million subscribers by 2007.

1. MY TOPIC

3. * 3G TECHNOLOGY IS THE RESULT OF DOWN BREAKING RESEARCH
AND DEVELOPMENT WORK CARRIED OUT BY ITU(INTERNATIONAL
TELECOMMUNICATION UNION) IN THE EARLY 1980S.
* 3G specifications and standards were developed in fifteen years. The
technical specifications were made available to the public under the name
IMT-2000. (INTERNATIONAL MOBILE TELECOMMUNICATION).
* THE COMMUNICATION SPECTRUM BETWEEN 400 MHZ TO 3GHZ
WAS ALLOCATED TO 3G.

4. * These include i-mode which provides e-mail and internet
access to over 50 million subscribers, and FOMA, launched in
2001 as the world's first 3G mobile service based on W-
CDMA.
* 1xEV-DO provides average download speeds of 600 Kbps to
1.4 Mbps, and average upload speeds of 500 to 800 Kbps, with
low latency, typically between 150 and 250 milliseconds.

5. * In Europe the leading country for 3G penetration is Italy
with a third of its subscribers migrated to 3G.
* Other leading countries for 3G use include UK, Austria,
Australia and Singapore at the 20% migration level.
* If using this definition, then the total 3G subscriber base
would be 475 million at June 2007 and 15.8% of all
subscribers worldwide.
