INTRODUCTION
Before knowing about 3G we need to know the basic types of networks viz.:-
SIMPLEX
DUPLEX
TRIPLEX
SIMPLEX
In case of walky talky only one person can speak at a time pressing the button such a situation is SIMPLEX. (1 way data transmission)
DUPLEX
Whereas a mobile phone allows simultaneous two way data transmission-a situation known as DUPLEX.
TRIPLEX(3G)
3G wireless technology represents the convergence of various 2G wireless telecommunications systems into a single uniform global system which includes terrestrial and satellite components in its functioning.
SPEED
Overcoming the slow speeds of previous networks it provides a high speed of 2Mbit/s to 14.4Mbit/s for a stationary user.
SECURITY
3G networks offer a greater degree of security than 2G predecessors.
End to end security is offered when application frameworks are accessed.
SPECTRUM
Bandwidth needed for 3G services is 15-20 Mhz much greater than 30-200 Khz for a 2G network.
CONCLUSION
3G has ability to unify existing cellular standards such as GSM, CDMA and TDMA providing much better speed, security, usage and additional features to capture today’s market.
