Bandwidth will always be the limiting factor in the development of applications and devices. Hence the short fall of 3G networks is clear, its just not fast enough, offering kbps doesnt meet the requirements of what the users expects now a days. The evolution from 3G to 4G will be driven by services that offer better quality video or sound i. Technology companies with 4G networks are knocking the door and mobile operators are beginning to answer.
The first generation 1G has fulfilled the basic mobile voice, while the second generation 2G has introduced capacity and coverage, later the third generation 3G which has a quest for data at higher speeds to open the gates for truly Mobile Broadband experience which will be further realized by the fourth generation. The fourth generation 4G will provide access to wide range of telecommunication services, advanced mobile services, supported by fixed networks, along with support of low to high mobility services and wide range of data rates.
If 4G is implemented correctly, it will truly harmonise global roaming, super high speed connectivity on every mobile communication device in the world. Some possible standards for the 4G system are The DARPA selected the distributed architecture and end-to-end Internet protocol, and believed at an earlier stage in peer-to-peer networking in which every mobile device would be both a transceiver and a router for other devices in the network, eliminating the spoke and hub weakness of 2G and 3G cellular systems.
In 4G systems, the circuit switched infrastructure is abandoned and only a packet switched network is provided, while 2. This Multiplexing , which is the key enabler of 4G Technology. Other technology aspects of 4G are adaptive processing and smart antennas, both of which will be used in 3G networks and enhance rates when used in with OFDM. The key concept is integrating the 4G capabilities with all of the existing mobile technologies through advanced technologies.
Application adaptability and being highly dynamic are the main features of 4G services of interest to users. These features mean services can be delivered and be available to the personal preference of different users and support the users' traffic, air interfaces, radio environment, and quality of service.
Connection with the network applications can be transferred into various forms and levels correctly and efficiently. The dominant methods of access to this pool of information will be the mobile telephone, PDA, and laptop to seamlessly access the voice communication, high-speed information services, and entertainment broadcast services.
The fourth generation will encompass all systems from various networks, public to private; operator-driven broadband networks to personal areas; and ad hoc networks. The 4G systems will interoperate with 2G and 3G systems, as well as with digital broadband broadcasting systems.
In addition, 4G systems will be fully IP-based wireless Internet. This all-encompassing integrated perspective shows the broad range of systems that the fourth generation intends to integrate, from satellite broadband to high altitude platform to cellular 3G and 3G systems to WLL wireless local loop and FWA fixed wireless access to WLAN wireless local area network and PAN personal area network , all with IP as the integrating mechanism.
With 4G, a range of new services and models will be available. These services and models need to be further examined for their interface with the design of 4G systems. Highlighting the primary drivers for 4G wireless systems are cost, speed, flexibility, and universal access.
There is no formal definition for what 4G is; however, there are certain objectives that are projected for 4G. These objectives include: that 4G will be a fully IP-based integrated system.
The term 4G is used broadly to include several types of broadband wireless access communication systems, not only cellular telephone systems. While neither standard bodies nor carriers have concretely defined or agreed upon what exactly 4G will be fourth generation networks are likely to use a combination of WiMAX and Wi-Fi technologies.
With 4G, a range of new services and models will be available. These services and models need to be further examined for their interface with the design of 4G.
Before 4G The process began with the designs in the s that have become known as 1G. Almost all of the systems from this generation were analog systems where voice was considered to be the main traffic. These systems could often be listened to by third parties. These 2G systems provided circuit switched data communication services at a low speed.
All the standards belonging to this generation were commercial centric and they were digital in form.
The second generation of wireless mobile communication systems was a huge success story because of its revolutionary technology and the services that it brought to its users. The systems in this standard are essentially a linear enhancement of 2G systems.
They are based on two parallel backbone infrastructures, one consisting of circuit switched nodes, and one of packet oriented nodes.
