GPRS is a
packet-switched upgrade to GSM. What consequences does packet-switching actually have on a
mobile network? How does GPRS perform in comparison with e.g. HSCSD? How will the GSM
networks need upgrading in order to implement GPRS ? Please note that a detailed
examination of GPRS will follow in chapter 4. However, this subclause will indeed address
some of the general issues surrounding GPRS. Feel free to follow our sequence by using the
menu bar at the bottom of the screen or make your own selection. |
