New fourth Generation (4G) mobiles

4G means Fourth-Generation Communications System.It is a term used to describe the next step in wireless communications. The data transfer rates are also much higher than previous generations.

A 4G system can provide a comprehensive IP solution where voice, data and streamed multimedia can be provided to users on an "Anytime, Anywhere" basis.

The main objectives or facilities of 4G are:

1)4g wireless broadband will be a fully IP-based integrated system.

2)It can provide high security and premium quality in business wireless internet,

3)This will be capable of providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors like unlimited wireless internet,

4)4g technology offer all types of services at an affordable cost.

5)4G technology allow high-quality wireless internet access smooth video transmission. It will enable fast downloading of full-length songs or music pieces in real time.

4G is developed to provide high quality of service (QoS) and rate requirements set by forthcoming applications.Those are  Multimedia Messaging, wireless broadband access, High definition TV content, Video Chat, Mobile TV, DVB, minimal service like voice and data, and other services.



The business and popularity of 4Gmobiles is predicted to be very vast. On an average, by 2009, this 4Gmobile market will be over $400B and it will dominate the wireless communications, and its converged system will replace most conventional wireless infrastructure.

Data Rates For 4G:

4G mobile data transmission rates are planned to be up to 20 megabits per second which means that it will be about 10-20 times faster than standard ASDL services.

The downloading speed for mobile Internet connections is from 9.6 kbit/s for 2G cellular at present. Unfortunately in actual use the data rates are usually slower, especially in crowded areas, when there is congestion in network.

In terms of connection seeds, 4G will be about 200 times faster than present 2G mobile data rates, and about 10 times faster than 3G broadband mobile.

3G data rates are currently 2Mbit/sec, which is very fast compared to 2G's 9.6Kbit/sec.
