What are 3G Phones?
Third generation mobile technology or 3G technology is just one more stage in the transformation of the mobile phone from a simple communication device in a multi function device. It was launched for the first time in Japan in 2001. This technology which uses higher bandwidth will enable users to send and receive data at speeds from 114 to 2000 kbps depending on whether the used is stationary or in motion which is way over the speed offered by any regular landline modem.
3G phones are mobile telephony devices that operate on the 3G network. These mobile receivers and transmitters are more expensive than earlier models of cellular phones and cannot operate on either a 1G or 2G network. Cellular phones were originally introduced in the 1980s when the Advanced Mobile Phone Service network was launched. This was the first generation network and operated with a technology called Frequency Division Multiplexing Access. This network was able to carry voice services over 800 megahertz frequency bands from phone to phone. Two different versions of 2G phones were implemented during the 1990s. The North American method employed the Code Division Multiple Access system that increased the telephony service to 64 users per channel. The rest of the world used the Time Division Multiple Access method that allowed for eight different users per channel. When the International Telecommunications Union introduced the IMT-2000 system, new models of cellular phones were int
