• 3G2 was developed by 3GPP2 for CDMA-based (code division multiple access) systems and is based on the MPEG-4 standard.
• It maintains more efficient audio codices, EVRC and QCELP that are not supported by 3GP.
• 3G2 files are generally more compact than 3GP files, and they run better on low-bandwidth fields.
