 | | GSM differs from its predecessors most significantly in that both signalling and speech channels are digital, which means that it is seen as a second generation (2G) mobile phone system. |
 | | GSM has remained backward compatible with the original GSM phones, at the same time, the GSM standard continues to develop and packet data capabilities were added in the Release '97 version of the standard with GPRS. |
 | | GSM's main competitor, CDMA2000, is used primarily in the United States, although it was seeing increased, but limited, worldwide adoption as a stepping stone to a 3G standard when WCDMA did not appear to be fully functional. |
