Difference between GPRS and EDGE

GPRS stands for  General packet radio services, It is used to give higher data speed over GSM, GPRS is the just extension to the older GSM technology to gain faster speed. Multimedia messaging services is the just features of GPRS. It allowed subscribers to send pictures, videos, or sound clips to each other just like text messages.  GPRS offer higher bit rate by the usage of a packet linked technology over GSM. 

EDGE called an Enhanced data rate for GSM Evolution, It also termed as Enhanced GPRS. EDGE technology that must use the same equipment as GSM with only a few minor modifications to provide faster speeds and is often regarded as a stepping stone towards 3G thus it is called 2.5G. EDGE is basically digital mobile phone technology but GPRS is mobile data services. 

Difference between GPRS and EDGE :

GPRS:

  • GPRS stands for General packet radio services.
  • GPRS is a mobile data service.
  • GMSK modulations must be used in GPRS.
  • The symbol rate of 270 ksym/s.
  • The modulation bit rate of 810 Kbps.
  • Radio data rate/ time slot 22.8 Kbps.
  • User data rate/ time slot 20 Kbps.
  • User data rate(8-time slots) is 160 Kbps
  • GPRS allows both 2G and 3G communication systems.

EDGE:

  • EDGE stands for Enhanced Data rate for GSM evolution.
  • EDGE is a digital mobile phone technology.
  • GMSK and 8-PSK modulation must be used for this technique.
  • The symbol rate of 270 ksym/s.
  • Modulation rate of 810 Kbps.
  • Radio data rate/time slot 69.2 Kbps.
  • User date rate/time slot 59.2 Kbps(MCS-9).
  • User data rate(8-time slots) is 473.6 Kbps.
  • EDGE allows existing TDMA and GSM  carriers to provide 3G services.
