System Architecture Evolution

System Architecture Evolution (aka 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 WiMAX or cdma2000)

Famous quotes containing the words system, architecture and/or evolution:

    I need not say what match I would touch, what system endeavor to blow up; but as I love my life, I would side with the light, and let the dark earth roll from under me, calling my mother and my brother to follow.
    Henry David Thoreau (1817–1862)

    I don’t think of form as a kind of architecture. The architecture is the result of the forming. It is the kinesthetic and visual sense of position and wholeness that puts the thing into the realm of art.
    Roy Lichtenstein (b. 1923)

    Analyze theory-building how we will, we all must start in the middle. Our conceptual firsts are middle-sized, middle-distanced objects, and our introduction to them and to everything comes midway in the cultural evolution of the race.
    Willard Van Orman Quine (b. 1908)
