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:
“Exploitation and oppression is not a matter of race. It is the system, the apparatus of world-wide brigandage called imperialism, which made the Powers behave the way they did. I have no illusions on this score, nor do I believe that any Asian nation or African nation, in the same state of dominance, and with the same system of colonial profit-amassing and plunder, would have behaved otherwise.”
—Han Suyin (b. 1917)
“All architecture is great architecture after sunset; perhaps architecture is really a nocturnal art, like the art of fireworks.”
—Gilbert Keith Chesterton (1874–1936)
“As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.”
—Thomas Henry Huxley (1825–95)
