Correct Answer: - GPRS uses 25 generation of GSM signals - The radio interface is the same that of GSM - GPRS uses 900 / 1800 Mhz, frequency band and GMSK modulation - The bit rates are EGPRS, similar to EDGE - Separate hardware and ports need to be added and availed

Correct Answer: - GPRS provide gross data rate of 2280 KBPS / time slot - Voice uses only 13KBPS/ time slot and the rest is consumed by Error Correction Code - Error connection code is utilized for detecting and correcting the transmission errors - As voice is compressed, the usage of Error connection code is mandatory

Correct Answer: - The maximum data rate supported by a GSM system is 96 kbps - However there are extensions to GSM standard to improve throughput - GPRS is one of the extended GSM service - The extended standards of GSM allows theoretical data rates on the order of 114 Kbit/s, but with throughput closer to 40Kbit/s in practice
