WHAT IS 4G? A wireless access technology and is the

successor of 3G. 4G stands for the fourth generation of cellular

wireless standards. It is a successor to 3G and 2G families of

standards. Speed requirements for 4G service set the peak download speed at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication. 

Enables seamless roaming between technologies.

One of the terms used to describe 4G is MAGIC—Mobile multimedia, Anytime anywhere, Global mobility support, Integrated wireless solution, and Customized personal service.A 4G system is expected to provide a comprehensive and secure all-IP based mobile broadband solution to smart phones, laptop computer wireless modems and other mobile devices.

WHAT'S NEW IN 4G?

HISTORY

This process began with the designs in the 1970s that have become known as 1G. Based on analog technology and the basic cellular structure of mobile communication.

The 2G (second generation) systems designed in the 1980s were still used mainly for voice applications but were based on digital technology, including digital signal processing techniques.

During the 1990s, two organizations worked to define the next, or 3G.

The 3G system would have higher quality voice channels, as well as broadband data capabilities, up to 2 Mbps.

An interim step is being taken between 2G and 3G, the 2.5G.

A very important aspect of 2.5G is that the data channels are optimized for packet data, which introduces access to the Internet from mobile devices, whether telephone, PDA

(personal digital assistant), or laptop.  4G This new generation of wireless is intended to

complement and replace the 3G systems, perhaps in 5 to 10 years.

CHARACTERISTICS

DRIVERS FOR ADOPTING 4G

Opportunity for bundling with other services

Reducing operational costs (OPEX) Introducing new applications and services Competition pressures Consolidating number of networks Multi-play devices available in the markets Multiple terminals Smart simplicity Outstanding performance

4G FEATURE

S Support interactive multimedia, voice, video, wireless internet and other broadband services.

High speed, high capacity and low cost per bit.

Global mobility, service portability, scalable mobile networks.

Seamless switching, variety of services based on Quality of Service (QoS) requirements.

Better scheduling and call admission control techniques.

Ad hoc networks and multi-hop networks.

FEATURE OF 4G MOBILE TECHNOLOGY

Based on open wireless architecture (OWA) Congregate several RTTs (radio transmission technologies) in one one device.The device would enable detachable unused modules.Amalgamate home phone, office phone and mobile phone into one common Personal device.

FEATURES OF 4G NETWORKS

4G networks are all-IP (Internet Protocol) based heterogeneous networks

This will allow users to: Select any system at any

time and any where Use Multiple systems at

the same time (e.g. GPS and WLANs and CDMA)

A wide range of applications using only one 4G integrated terminal

Support interactive multimedia services: teleconferencing, wireless Internet, etc.

Wider bandwidths, higher bit rates. Global mobility and service portability. Low cost. Scalability of mobile networks (>10 times the

capacity of 3G).

This new generation of wireless is intended to complement and replace the 3G systems, perhaps in 5 to 10 years. Accessing information anywhere, anytime, with a seamless connection to a wide range of information and services, and receiving a large volume of information, data, pictures, video, and so on, are the keys of the 4G infrastructures.

CONCLUSION:

.

As the history of mobile communications shows, attempts have been made to reduce a number of technologies to a single global standard. Projected 4G systems offer this promise of a standard that can be embraced worldwide through its key concept of integration. Future wireless networks will need to support diverse IP multimedia applications to allow sharing of resources among multiple users. The fourth generation promises to fulfill the goal of PCC (personal computing and communication)—a vision that affordably provides high data rates everywhere over a wireless network
