1. Introduction to 3G Wireless
3G stands for third generation, and is a wireless industry term for a collection of international standards and technologies aimed at increasing efficiency and improving the performance of mobile wireless networks.
3G wireless services offer enhancements to current applications, including greater data speeds, increased capacity for voice and data and the advent of packet data networks versus today’s switched networks.
As second-generation (2G) wireless networks evolve into third-generation systems around the globe operators are working hard to enable 2G and 3G compatibility and worldwide roaming, including 3G UMTS, GSM, GPRS, IS-95A/B, 3G CDMA2000 1X and CDMA2000 1xEV technologies.
2. The Different Types Of 3G
3G is a generic term covering a range of future wireless network technologies, including WCDMA, CDMA2000, UMTS and EDGE.
3G combines high-speed mobile access with Internet Protocol (IP) based services. This doesn't just mean fast mobile connection to the World Wide Web - by liberating us from slow connections, cumbersome equipment and immovable access points, 3G will enable new ways to communicate, access information, conduct business and learn.
