ABSTRACT 4G TECHNOLOGIES Wireless technology has transformed our lives in many ways. Until very recently‚ we needed a computer wired to a port‚ to get online. Even wired telephones are becoming a thing of past. Nowadays‚ we use our mobile phones for banking‚ to check ticket availability at a Cinema Hall‚ and many more. Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”. And‚ Wireless networking refers to any kind

3G TECHNOLOGY Mobile telephones‚ the 1st generation of which were introduced in the mid-1980’s‚ have been constantly evolving since their inception. Today‚ over 2B mobile phones are in usage and around 80% of the world’s population is within reach of a mobile phone signal. Mobile phones have traditionally been used for voice communications‚ but today can serve as the platform for a variety of communication outputs -- including data and video. 3G is the third-generation of mobile phone technology

network * Second generation (2G) digital cellular networks * Third generation (3G) broadband data services to the current state of the art * Fourth generation (4G) native-IP networks. 1G (or 1-G) refers to the first-generation of wireless telephone technology‚ mobile telecommunications. These are the analog telecommunications standards that were introduced in the 1980s. The main difference between two succeeding mobile telephone systems‚ 1G and 2G‚ is that the radio signals that 1G

systems were deployed. At the same time‚ the cellular industry began developing the second generation of mobile telephony (2G). The difference between 1G and 2G is in the signaling techniques used: 1G used analog signaling‚ 2G used digital signaling. As experience shows‚ the lead-time for mobile phone systems development is about 10 years. It was not until the early to mid 1990s that 2G was deployed. Primary thinking

The 2G was only operational in Europe as other regions and standard organisation outside Europe had their own standards which made the ETSI 2G not to be globally interoperable. The quest

I. INTRODUCTION Mobile devices are getting smaller‚ lighter‚ and more powerful; they have bigger screens and longer battery life‚ more features and more capabilities. Things like watching the football game on your mobile device‚ watching movies‚ videoconferencing‚ paying your bills and downloading music to the palm of your hand will become second nature in the future. Bandwidth will always be the limiting factor in the development of applications and devices‚ be it wired‚ or wireless. At the
