System Architecture Evolution

System Architecture Evolution (SAE) is the core network architecture of 3GPP‘s LTE wireless communication standard.

SAE is the evolution of the GPRS Core Network, with some differences:

  • simplified architecture
  • all-IP Network (AIPN)
  • support for higher throughput and lower latency radio access networks (RANs)
  • support for, and mobility between, multiple heterogeneous access networks, including E-UTRA (LTE and LTE Advanced air interface), 3GPP legacy systems (for example GERAN or UTRAN, air interfaces of GPRS and UMTS respectively), but also non-3GPP systems (for example WiFi, WiMAX or cdma2000)
