3G-TECHNOLOGY OF MODERN ERA

In past few decades science and technology has tried to reduced lots and lots of human effort.The most recent example of  its application is invention of 3G mobile phones.

Being an Electronics and Communication engineer I think that the invention of 3G phones by International Mobile Telecommunication is one of the most succesfull invention in the field of telecommunication.Comparing 3G mobile with other mobile,it offers simultaneous use of speech and data services and higher data rates.Though 3G mobiles requires large bandwith of signal and information area but
this requierment has reduced the effort to operate computer or laptop for internet.
Some of the application of 3G mobiles are-
Mobile TV - a provider redirects a TV channel directly to the subscriber's phone where it can be watched.


Video on demand - a provider sends a movie to the subscriber's phone.

Video conferencing - subscribers can see as well as talk to each other.

Tele-medicine - a medical provider monitors or provides advice to the potentially isolated subscriber.

Location-based services - a provider sends localized weather or traffic conditions to the phone, or the phone allows the subscriber to find nearby businesses or friends
 
 
What else is needed in mobile phone???
By the invention of this 3G technology it is being predicted that in upcoming 10-15 yrs people will not carry laptop to their office because this 3G system is nothing but mobile cum computer.
