SAE Network Summary
The System Architecture Evolution was developed to provide a migration path for 3GPP systems and introduce higher
data rates and lower latency for a variety of radio access technologies. SAE defines the packet network supporting the
high-bandwidth radio network as the Evolved Packet Core (EPC). The EPC provides mobility between 3GPP (GSM,
UMTS, and LTE) and non-3GPP radio access technologies, including CDMA, WiMAX, WiFi, High Rate Packet Data
(HRPD), evolved HRPD, and ETSI defined TISPAN networks.
The following figure shows the interworking of the EPC with the different radio access technologies.
