3G technology was first launched by Japan in 2001. It has walked the path of technological advancement path to a great extent after its evolution. It has invaded the wireless world. Wireless videophones and high speed internet has become a possibility with this easy to use or gadget friendly technology. The wireless phone industry has also switched to a wireless, broadband, high speed packet based network from a more usual system of circuit switched communications. It worth mentioning that, this has been preceded by second generation digital, first generation analog, communication technologies.
Like the 3G Mobile Phones, the wireless mobile network can transfer data at a speed of 384 Kbps. Normally, the speed of a 3G network ranges between 64Kbps and 384 Kbps. But in places like United States, common wireless data transfer may be as slow as 14.4 Kb modem. It is in fact a high speed broadband mobile internet access. In future, it is expected that the 3G network would reach a speed that would be more than 2Mbps. Research for accomplishing this level is still going on.
With the support of 3G network one can turn phone and other devices into multimedia players. This in turn would help in downloading music and video clips. There are services (FOMA to name one) that use technology like W-CDMA and CDMA-one that are used in different formats in different frequencies in different works. But they also use more bandwidth than the digital voice services available in most of the phones.
