It is really a expression used to represent the next generation of mobile telecommunications technology. This can be a group of standards employed for mobile products and mobile telecommunication services and systems that adhere to the Worldwide Mobile Telecommunications-2000 (IMT-2000) specifications through the Worldwide Telecommunication Union. 3G finds application in wireless voice telephony, mobile Access to the internet, fixed wi-fi access, video calls and mobile TV. The UMTS system, first offered in 2001, standardized by 3GPP, used mainly in Europe, Japan, China (though another radio interface) along with other regions predominated by GSM 2G system infrastructure. The mobile phones are usually UMTS and GSM hybrid cars. Several radio connects can be found, discussing exactly the same infrastructure.
Several telecommunications companies market wireless mobile Internet services as 3G, showing the marketed services are provided on the 3G wireless network. Services marketed as 3G are needed to satisfy IMT-2000 technical standards, including standards for reliability and speed (bandwidth rates). To satisfy the IMT-2000 standards, a method is needed to supply peak data rates with a minimum of 200 kbit/s (about .2 Mbit/s). However, many services marketed as 3G provide greater speed compared to minimum technical needs for any 3G service. Recent 3G releases, frequently denoted 3.5G and three.75G, offer special broadband access of countless Mbit/s to mobile phones and mobile modems in laptops.
