3G Access


Currently, third-generation mobile wireless services (3G) are coming onto the market that will allow users access the Internet, transmit data and voice, and utilize various multimedia services at speeds of 2 mbps or higher.

3G technologies are turning telephones and other devices into multimedia players, making it possible to download music and video clips. The new service is called the freedom of mobile multimedia access (FOMA) and it uses wideband code division multiple access (W-CDMA) technology to transfer data over its networks. W-CDMA sends data in a digital format over a range of frequencies, which makes the data move faster (but also uses more bandwidth than digital voice services). W-CDMA is not the only 3G technology; competing technologies include CDMAOne, which differs technically but should provide similar services.
