WHY 3G ? LIMITATIONS OF 2G :
Compared to the older 2G and 2.5Gstandards, a 3G system must allowsimultaneous use of speech and data
services, and provide peak data rates of atleast 200 kbit/s according to the IMT-2000specification.
Recent 3G releases, often denoted 3.5Gand 3.75G, also provide mobile broadband
access of several Mbit/s to laptop computers

OVER VIEW OF 3G :
3G is the third generation of wirelesstechnologies. It comes with enhancements overprevious wireless technologies, like high-speedtransmission, advanced multimedia access and
global roaming.
3G is mostly used with mobile phones and
handsets as a means to connect the phone tothe Internet or other IP(Internet Protocol)networks in order to make voice and video calls,to download and upload data and to surf the net.

WHAT IS 4G ?
The key concept is integrating the 4G capabilities with allof the existing mobile technologies through advanced
technologies.
Application adaptability and being highly dynamic arethe 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 usersand support the users' traffic, air interfaces, radioenvironment, and quality of service.
Connection with the network applications can be
transferred into various forms and levels correctly andefficiently.
The dominant methods of access to this pool ofinformation will be the mobile telephone, PDA, and
laptop to seamlessly access the voice communication,hi h-s eed information services and entertainment

VISIONS OF 4G :
4G will extend to an all-IP network (access+core)that integrates broadcast, cellular, cordless, WLAN,short-range systems and fixed wire.
The vision is of integration across these network--air interfaces and of a variety of radio environmentson a common, flexible and expandable platform ofnetwork of networks with distinctive radio accessconnected to a seamless IP-based core network.

APPLICATIONS :
Virtual Presence : This means that 4G provides user
services at all times, even if the user is off-site. Virtual navigation : 4G provides users with virtual
navigation through which a user can access a databaseof the streets, buildings etc.
Tele- geoprocessing applications: This is acombination of GIS (Geographical Information System)and GPS (Global Positioning System) in which a usercan get the location by querying.
Tele-Medicine and Education : 4G will support remotehealth monitoring of patients. For people who areinterested in life long education, 4G provides a goodopportunity.
Crisis management: Natural disasters can cause
