4G Technology (Fourth Generation (4G) mobiles)
« on: January 17, 2011, 08:29:33 PM »

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

The main objectives of 4G are:

1)4G will be a fully IP-based integrated system.

2)This will be capable of providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors.

3)It can provide premium quality and high security.

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

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

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

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:

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

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.

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.

It can be possible if we have our own satellite...and u are absolutely right,It's very costly to use internet in our country..so it's very urgent to set up a satellite of our own to build up a BANGLADESH as a powerful nation...
