WHAT IS OFDM? ULTRA WIDE BAND SMART ANTENNA IPV6.0 SOFTWARE DEFINED RADIO MIMO CONCLUSIONPowerPoint Presentation: 4G Mobile technology - The mobile race to innovation.PowerPoint Presentation: INTRODUCTION WHAT IS 4G ? 4G is the short name for fourth generation. The term 4G is used broadly to include several type of broadband wireless access communication not only cellular telephone system.PowerPoint Presentation: One of the term used to describe 4G is MAGIC The fourth generation of mobile networks will truly turn the current mobile phone network in to end to end IP based network , data, gaming M obile multimedia. A nytime anywhere. G lobal mobility support. I ntegrated wireless solution and C ustomized personal service .PowerPoint Presentation: H I S T O R Y Generation refers change in nature of service compatible transmission technology and new frequency bands.PowerPoint Presentation: FIRST GENERATION CELLULAR COMMUNICATION ( 1G ) 1G was analog system and was developed in 1970’s It was based on FDMA, it allows users to make voice calls in one country.PowerPoint Presentation: SECOND GENERATION CELLULAR COMMUNICATION (2G ) 2G phones launched on global system for mobile communication ( GSM ) standard and was developed in 1990’s. It was based on CDMA.PowerPoint Presentation: THIRD GENERATION CELLULAR COMMUNICATION ( 3G ) The 3G technology adds multimedia facilities to 2G phones by allowing videos, audio and graphic applications. It support both packet switched and circuit switched data transmission.PowerPoint Presentation: 4G is the fourth generation of cellular wireless standards. It is based on packet switched network. The 4G network will consist of a set of various network using IP as a common protocol. FOURTH GENERATION CELLULAR COMMUNICATION (4G)PowerPoint Presentation: Multi-technology Approach Many technologies are competing on the road to 4G, as can be seen in Figure 3.PowerPoint Presentation: WHAT’S NEW IN 4G ? High transfer rate. Internet access any where. Ability to move around with the same IP address. Utilization of smart antenna. High resolution mobile TV.PowerPoint Presentation: HOW 4G BECOMES FASTER WIRELESS TECHNOLOGIES USED IN 4G:- OFDM ( Optical frequency division multiplexing ) UWB ( ultra wideband ) SMART ANTENNA. IPv6.0 S.D.R ( SOFTWARE DEFINED RADIO. ) MIMO(Multiple Input – Multiple Output )PowerPoint Presentation: What is OFDM ? OFDM stands for Orthogonal Frequency Division Multiplexing. It Transmits large amounts of digital data over a radio wave. HOW IT WORK :- It distributes the data over a large number of carriers that are spaced apart at precise frequencies. This spacing provides the “ Or th og ona l ity ” in this technique which prevents the demodulators from seeing frequencies other than their own.PowerPoint Presentation: ULTRA WIDE BAND An advanced technology that can be used in 4G technology. Frequencies that are currently in use by other radio frequency devices . It uses a frequency of 3.1 to 10.6 Hz. It uses less power, since it transmits pulse instead of continuous signal.PowerPoint Presentation: SMART ANTENNA Smart antenna can be employed to find tune ,and turn up signal information. Smart antenna can send signal back in the same direction that they come from. Allow the same radio frequency to be used for other user without worry of interference.PowerPoint Presentation: IPv6.0 IPv6 means Internet Protocol Version 6 . The Internet Protocol (IP) is the method or protocol which data is sent from one computer to another on the internet. Each computer (known as a host) on the Internet has at least one IP that uniquely identifies it from all other computers on the Internet. It includes 128 bits, which is 4 times more than 32bits IP address in IPv4.PowerPoint Presentation: SOFTWARE DEFINED RADIO A software defined radio is one that can be configured to any radio or frequency standard through the use of software. The phone should automatically switch from operating on a CDMA frequency to a TDMA frequency whenever it is required. Roaming can be an issue with different standards, but with a software defined radio, users can just download the interface upon entering new territory, or the software could just download automatically.PowerPoint Presentation: MULTIPLE INPUT – MULTIPLE OUTPUT (MIMO) MIMO uses signal multiplexing between multiple transmitting antennas (space m ultiplex) and time or frequency.PowerPoint Presentation: CONCLUSION Delivers true speeds without wires. Faster -- more bandwidth. Completely portable . 3 times faster than 3G . 4G is broadband technology that will give us richer, pleasurable, internet experience.PowerPoint Presentation: THANK YOU You do not have the permission to view this presentation.
