4G wireless mobile communication networks are been specified to support display, battery and computational power etc. 4G wireless mobile communication networks should not focus on air interface and data rate, but instead cover advance wireless mobile communication networks and high speed wireless access system into different platforms. The era of new wireless communication is evolving and it will soon penetrate into daily life and change the way we live. The key concept is integrating the 4g capabilities

The Current Status of 3G and the Future of 4G 3G and 4G are two mobile communications standards that are currently in use. 3G is the third generation of the standard and 4G is the fourth and most recent generation. Each successive generation usually brings new base technologies, more network capacity for more data per user, and the potential for better voice quality. 3G became available in the United States in 2002 and 4G became available in 2009 (O’Malley). Although it is a previous

The First Generation of communication system is the Analog cellular system, means carrier is Analog. we just send wave forms primarily with voice. it is continuous in amplitude and time. variation in a signal disrupts over long distance . This Analog system was introduced in seventies.NMT , AMPS, TACS, CDPD technologies were used in 1G. It uses FDMA technique call to one country. All the Analog systems were used circuit switched technology and design only for voice communication not data. The cost

1.1 INTRODUCTION The aim of third and fourth generation (3G/4G) mobile networks is to provide users with high data rates, and to provide a wider range of services, such as voice communications, videophones, and high speed Internet access. A common challenge in a wireless system design is to overcome the eects of the wireless channel, which have multiple transmission paths and dierent delays. OFDM has a promising future as a new technology in several next generation wireless communication systems

Introduction: In an ever-evolving world , people come up with new idea each day , some of them are in the field of robotics , some in computer security and some are in computer networks. Well the Network industry has risen up and been on a peak ever since 2008 , with new technologies coming by every year , but they had to slow the roll down of such innovations in the field just to make the previous technology have a good life span and make devices adapt to a certain technology for a certain time

NETWORK EVOLUTION in 3G / 4G Abstract: During the 20th century, the key technology was information gathering, processing and distribution. This total technology will depend based on the network systems. Which are nothing but grouping of systems that should be controlled by a server. In business and home applications, mobile users and in all social issues the networks are used . To enhance the benefits of these networks, we are introducing 3G systems. The aim of the 3G security architecture

customers and service providers alike. Enter the fourth generation (4G) wireless network. Unlike earlier wireless standards, 4G technology is based on TCP/IP, the core protocol of the Internet. TCP/IP enables wireless networks to deliver higher-level services, such as video and multimedia, while supporting the devices and applications of the future. Verizon Wireless chose LTE over WiMAX as the technological foundation for its 4G wireless broadband

designed for voice communications with no real thought given to data. The introduction of 2.5G in the late 1990s allowed for data activities such as sending and receiving email and web browsing. It is the third and the current fourth generation, 3G and 4G, that consumers are most familiar with that ushered in today’s mobile data usage. 3G was introduced to the United States in 2003 “with minimum consistent Internet speeds of 144Kbps” (Segan, 2013, para 3) and are capable to get a data connection “anywhere
