The term 3G refers to the third generation of mobile telephone standards, as defined by the International Telecommunication Union (ITU). 3G technologies allow mobile operators to offer more service options to their users, including mobile broadband access. The 3G service offers greater flexibility and services, making more efficient use of mobile bandwidth than its predecessor, the 2G.
The relationship between 2G and 3G is similar to the relationship between dial-up internet and broadband internet or analog TV with digital TV. In all of these examples, increased spectral efficiency has enabled more choices for the consumer and more effective service. By trading for kids, more data can be transmitted faster.
3G technologies allow devices such as mobile phones and mobile modems to connect to broadband internet at good speed. Most new cell phones are 3G enabled, making it easy to check email and surf the web anywhere.
Mobile broadband via modems and smartphones took off extremely fast. Mobile broadband allows customers to browse the Internet, check emails, download files, music and video clips on their laptops and PCs where coverage is available.
3G technology is possible thanks to two complementary technologies – HSDPA and HSUPA (high speed download and upload packet access, respectively). These technologies allow mobile broadband users to access download speeds of up to 21Mbps and upload speeds of up to 1.76Mbps through a mobile modem or any other device that connects to the 3G network.
3G predecessors such as 2G and GPRS technologies offer limited Internet connectivity, which was often expensive and slow. On the other hand, because 3G uses the radio waves more efficiently, it is able to offer higher speeds with cheaper prices for the data packets, becoming one of the leading cars in the advertisements and sales of the telephone operators in the Brazil.
