4G Wireless Technology

By Ram Chaturvedi

Technology makes new life in this world. Communication systems are the major part in our technology. 3G communication systems are still facing so many problems in communication network. 4G technology "Fourth Generation communication systems" are the new latest technology which deals with networking and communication systems. Mean while these 4G technology giving solutions for problems of 3G systems.

The main features of 4G communication systems to expand a wide range of new latest services like wireless communications. Depending upon data rates it introduces different types of wireless broadband communications systems.

"MAGIC" is the word which gives u proper definition of 4G communication systems. MAGIC - "Mobile multimedia, anytime anyplace, Global mobility support, integrated wireless solution, and customized service". One of the main parts of 4G Communications systems are "cellular broadband wireless access systems" showing much interest to developing the mobile communication technology.

This new generation of wireless communication systems replaces the 3G systems , in 5 to 10 years. It can be used to access the data information from any place, any time, with a seam less connection to a wide range of information and services.

The main features of 4G communication systems are to handle huge amount of data from any palace to wide range of services. 4G systems are used to maintain and develop the different types of networks using IP -internet protocol as single protocol.

Every time Latest technologies will focus on business expectations. 4G systems and its applications make growth in the consumer and business development. Survey of Japan local papers says that few top countries are Japan, china, and South Korea are that they decided to work on developing new technologies such as 4G mobiles. Few days back one meeting was happened in Seoul in March with officials from the above countries, they decided to work and share information on developing 4G mobile phones.

Compared to 3G technologies, this 4G technology much faster communication speed nearly "100 Mbps" .it supports new latest protocol version "IPV6". 4G communication systems provide high capacity and diverse usage formats. These formats mostly used in public networks like optical fibers and "wireless LAN".

Technology always needs new changes. Still some technology companies are incorporating new latest technical changes in cellular communications. Even they are calling "2.5G", "3.5 G". In future 4G will occupy top place in communication systems and it will replaces all these 2.5G and 3.5G. - 23802
