4G Mobile Communication Systems

The popularity and evolution of mobile devices like laptops, mobile phones and Personal Digital Assistants (PDA), and the evolution of fast mobile networks in the last decade, have made it possible to increase the complexity of mobile applications and services provided to end-users. It is also a spectacular growth in multimedia communication especially via the World Wide Web.

This paper explore some of the current technology of mobile devices, mobile networks and multimedia systems, and is based on the exploration outline some issues for design and development of mobile multimedia systems in 4G Mobile Communication System.

Fourth-generation mobile communication systems will combine standardized streaming with a range of unique services to provide high-quality content ( Multimedia ) that meets the specific needs of the rapidly growing mobile market. By offering higher data-transmission rates up to 20 Mbps more than 3G for wide-area coverage and local-area coverage, 4G systems will be able to provide high quality streamed content to the rapidly growing mobile market.

4G mobile communications will have transmission rates up to 20 Mbps_ higher than of 3G. The technology is expected to be available by the year 2010. 4G is being developed with the following objectives:

1. Speeds up to 50 times higher than of 3G. However, the actual available bandwidth of 4G is expected to be about 10 Mbps.
2. Three-dimensional virtual reality_imagine personal video avatars and realistic holograms, and the ability to feel as if you are present at an event even if you are not. People, places, and products will be able to interact as the cyber and real worlds merge.
3. Increased interaction between corroborating technologies; the smart card in your phone will automatically pay for or will tell your car to warm up in the morning as your phone has noted you leaving
the house. We can use new technology such as CDMA wireless access technology, advanced antenna systems, next-generation mobile Internet, quality of service, power amplifier technology, and wireless access networks in 4G mobile communication system.

4G applications include high-performance streaming of multimedia content based on agent technology and scaleable media coding methods. 4G will solve problems like limited bandwidth in 3G when people are moving and uncertainty about the availability of bandwidth for streaming to all users at all times.
