Mobile Communication Abstract

Mobile communication has become essential for most people as the population has grown and the need for communication has increased. Mobile communication allows the exchange of voice and multimedia data without a physical or fixed link. There are several mobile technologies including 2G, 3G, 4G, WiMAX, Wibro, EDGE, and GPRS. While 1G used analog signals and 2G used digital, 3G networks unified standards and used higher frequencies. 4G networks use an ad hoc model without routers and are designed to send data over hundreds of parallel streams via OFDM, increasing information sent over traditional CDMA networks. This document focuses on 4G technology as an extension of 3G with more bandwidth for high quality audio and video

ABSTRACT
Mobile communication is evolving day by day and has become a must have for everyone. Mobile communication is nothing but the exchange of voice and multimedia data using a communication infrastructure at the same time regardless of any physical or fixed link. Ever since the population has been increasing, it urges the need for communication and the most familiar application of mobile communication is the mobile phone. Many mobile technologies available today such as 2G, 3G, 4G, WiMAX, Wibro, EDGE, GPRS and many others. The first generation i.e, 1G is based on analogue transmission ,second generation on digital transmission and the third generation of mobile systems unifies different mobile technology standards, and uses higher frequency bands for transmission and Code Division Multiple Access to deliver data And 4G is based on an ad hoc networking model where ad hoc network refers to a network connection established for a single session and does not require a router or a wireless base station. Currently 3G networks still send there data digitally over a single channel, OFDM is designed to send data over hundreds of parallel streams, thus increasing the amount of information that can be sent at a time over traditional CDMA networks. The design of 4G will be based on OFDM (Orthogonal Frequency Division Multiplexing), which is the key enabler. Here in this mobile communication we are mainly going to represent about the 4g technology which is basically the extension in the 3G technology with more bandwidth and the expectation of high quality audio/video streaming over end to end Internet Protocol.
