System Architecture Evolution

<p>System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group <a href="/facts/3GPP/TBrQYKFF">3GPP</a>'s <a href="/facts/3GPP_Long_Term_Evolution/72QhwXHT">LTE</a> wireless communication standard.
</p><p>SAE is the evolution of the <a href="/facts/GPRS_Core_Network/Ju1sjTls">GPRS Core Network</a>, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency <a href="/facts/Radio_access_network/SSlTWVAj">radio access networks</a> (RANs); and support for, and mobility between, multiple heterogeneous access networks, including <a href="/facts/E-UTRA/4ybGEVy6">E-UTRA</a> (<a href="/facts/3GPP_Long_Term_Evolution/72QhwXHT">LTE</a> and <a href="/facts/LTE_Advanced/Wzh6skhG">LTE Advanced</a> air interface), and 3GPP legacy systems (for example <a href="/facts/GERAN/gsRldX41">GERAN</a> or <a href="/facts/UTRAN/pft9MQse">UTRAN</a>, air interfaces of <a href="/facts/GPRS/c4SJD7ov">GPRS</a> and <a href="/facts/UMTS/lhy2RrMw">UMTS</a> respectively), but also non-3GPP systems (for example <a href="/facts/Wi-Fi/u94quCsx">Wi-Fi</a>, <a href="/facts/WiMAX/tz9zpKHU">WiMAX</a> or <a href="/facts/CDMA2000/yF4B3rfl">CDMA2000</a>).
