INTRODUCTION
4G stands for Fourth (4th) Generation of tele communication Technology.
But at this time nobody exactly knows the true 4G definition
4G Technology is basically the extension of the 3G technologies with more bandwidth and transmission speed
Why 4G?
4G Technology offers high data rates that is
1gbps for stationary users
100 mbps for mobile users
How this is possible
OFDMA:Orthogonal frequency-division multiple access
MIMO: multi in multi out transmition and reception
Packet switching
FEATURES
Smooth handovers across heterogeneous networks
Dynamically share the network resources to support more simultaneous users per cell.
Interoperability with existing wireless standards
it require less complexity for equalization at the receiver.
High privacy
conclusion
4g technology should be implemented as early as possible particularly in india
4g should be available for rural areas also
