Introduction

Britain's first testing of advanced generation mobile broadband is in the process and Cornwall; it is about the technological advancement of using internet on the go, many times faster than the traditional networks. A union recently suggested the government that they should use some of the revenues from the 4G spectrum in order to expand broadband access in UK (Vlachos, 2010, 11-19).

4G is the fourth generation of cellular standards, and it is the advanced generation of 2G and 3G families. In 2009, ITU-R organization defined requirements for $G standards. They set the highest speed capabilities for 4G service of 100 megabytes for high communication on the go like in trains and cars, and 1 gigabyte for low speed communication (Vlachos, 2010, 11-19).

The 4G system initially started by the Defence Advanced Research Projects Agency (DARPA). The DARPA selected the architecture of distribution, end-to-end Internet protocol (IP), and suggested that at an initial stage in peer networking, in which every mobile device acts as a transceiver and a router both for other devices and the network by overcoming the spoke-and-hub lankness of 2G and 3G systems.

2.5 GPRS cellular systems helped us by providing dual infrastructure like packet switched nodes and circuit switched nodes for data services and voice calls respectively. In 4G system, the switched infrastructure for the circuit is not anymore, and just a packet switched network is available. It shows that, on 4G, the traditional voice call system has now sent back with the IP technology.

4G systems allow secure mobility; which means that file transfer would not be stopped even if a terminal moves from one cell to another, but handover takes place. The terminal also make sure that the IP address would remain same, even during movement of the cell, which means that mobile server would remain in access if it remains in the coverage area. In 4G generation, this movement as possible with the help of IP protocol and IP version 6, whereas, in the preceding generations, it was only achievable with the help physical layer & data link layer communication protocols. Adding up, 4G system provides flexibility, in addition to flawless mobility, 4G provides compromising of the different kinds of on hand cellular networks, like cellular, satellite, PAN, WLAN and systems for getting permanent wireless networks. (Mishra, 2007, 12-19).

While managing optimum mobility, 4G will proposes very extravagantly data rates with the prospect of 100 bytes per second cellular services. The improved bandwidth and high data broadcast rates permit 4G consumers the capability to make use of HD movies & web based video conferencing characteristics of cellular devices accompanied a 4G system. The 4G network system as predictable for giving a complete IP result where more multimedia system applications and activities can present to the individual on an 'Anytime, Anyplace' base with an acceptable eminent data rate, finest choice and the high security.
