Fourth Generation (4G) Mobile Technology

    The 4G also knows as fourth generation of cellular wireless standards or called as Fourth-Generation Communications System. The 4G System is a term used to describe the next step in wireless communications, the successor of 2G and 3G standards. This system can provide a comprehensive IP solution where voice, data and streamed multimedia can be provided to users on an "Anytime, Anywhere" basis. Its aim is to provide a wide range of data rates up to ultra-broadband Internet access to mobile as well as stationary users. 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 mbps and 1 gbps
           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 set to deliver 100mbps to a roaming mobile device globally, and up to 1gbps to a stationary device. With this in mind, it allows for video conferencing, streaming picture perfect video and much more. It 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.

    The world is moving rapidly towards this 4G open mobile movement. In China, the government has in fact, targeted for 4G mobile industry. In European Union, evolution to 4G has been the mission-critical strategy since 2003. Japan and Korea started 4G regulations in 2002. The US mobile market is a pretty different case, because FCC as a law enforcement agency basically has no power to enforce law. The operators pay huge to the congress, and congress manages the FCC. So eventually, the operator "makes" the law. However, nobody can stop future and it is just a matter of time when this 4G open mobile comes to life.
