Take a look on how data-rate of cellular technology grows !
Since GSM technology phase 1 was published on around 1990, and then continued to phase 2 (HSCSD, GPRS, and EDGE), data rate evolution was achieved by enhancing coding scheme, introducing new network elements and protocols.
By now, data rate are even more increased with implementation of packet switch network. Bridge to this evolution were GPRS, with new packet switch network element and protocols introduced.
As we all well-aware with, the so-called HSDPA, HSUPA and another High Speed technology just one step away from our front door, waiting to show us the meaning of “speed”.
The world indeed are evolving ..
