Answer / archana

Enhanced GPRS are already specified. The more important
difference is the modulation scheme used, 8 PSK that
provides Spectral Efficiency of 3 bit/s/Hz. The modulation
used in GPRS is the same used in GSM, the GSMK that provides
Spectral Efficiency of 1 bit/s/Hz.

Answer / edwin jose

GPRS is based on a modulation technique called Gaussian
minimum-shift keying (GMSK).

Answer / santhosh

the modulation in gprs depends on sample rate . depending
on either gmsk or qpsk ca be used.

Answer / junaise

GPRS uses same Modulation as GSM. Which is GMSK(Gausian
Minimum Shift Keying). According this can have speed of
233Kbps(67Khz X 4) max. That's y in GSM we can use the GPRS
also.

Answer / ravi surya

GPRS is used same as GSM Modulation technique known as Gaussian minimum-shift keying (GMSK.Depends upon the data throughput.If the data throughput is high use 8 PSK modulation technique.
