UMTS stands for "Universal Mobile Telecommunications System".
The 3rd Generation Partnership Project (3GPP) has been responsible for generating the technical specifications which defines the UMTS protocols and performance requiremnts.
Based on time to time requirements from both Operators and Users, the technical specifications continue to evolve e.g. from only circuit switched call to normal packet switched call to hsdpa call to hsupa call and so on.
With increasing requirements like high data rate, high throughput, multiple services at a time, everyone talking and putting continuous efforts to achieve them.
