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 standard applications 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.
One of the terms used to define 4G Communications systems is MAGIC – “Mobile multimedia, anytime anyplace, Global mobility support, integrated wireless solution, and customized service.” 4G Communications systems that’s cellular broadband wireless access systems have been attracting much interest in the mobile communication technology.
A change in technology makes latest services. 4G communication systems occupies new top place in wireless communication systems. It replaces all 2G and 3G systems. 4G systems handles very huge amount of data from any place at any time to wide range of data and services.
The main functions of 4G systems are to handle huge amount of data, pictures, etc. the main future vision of 4G systems are to maintain and develop the different types of networks using IP -internet protocol as single protocol. Because of this service we can access every technical application.
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.
4G mobile phone technology supports IPv6 – “Internet Protocol version 6” and provides faster communication speeds “100 mbps “, capacity and diverse usage formats. These formats would support for other public networks such as optical fiber and wireless local area networks.
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.

A mobile phone is a telephone that can make and receive calls over a radio frequency carrier while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Most modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are often also called cellular telephones or cell phones. In addition to telephony, modern mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming, and photography. Mobile phones which offer these and more general computing capabilities are referred to as smartphones.
SAR (specific absorption rate) is an indication of the amount of radiation that is absorbed into a head whilst using a cellular phone, the higher the SAR rating the more radiation that is absorbed into the head.
A SAR value is a measure of the maximum energy absorbed by a unit of mass of exposed tissue of a person using a mobile phone, over a given time or more simply the power absorbed per unit mass. SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue.
