What is 3G? 3G (Third Generation) is a generic name for

a set of mobile technologies.

Data speeds in 3G networks 2 Megabits per

second

Radio communications technology that will

create a "bit pipe" for providing mobile

access to internet-based services.

3G services will add an invaluable mobile

dimension to services that are already

becoming an integral part of modern

business life
