System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group 3GPP's LTE wireless communication standard.. SAE is the evolution of the GPRS Core Network, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency radio access networks (RANs); and support for, and mobility between, multiple ...
One of the key technologies for 4G and beyond is called Open Wireless Architecture (OWA), supporting multiple wireless air interfaces in an open architecture platform. SDR is one form of open wireless architecture (OWA). Since 4G is a collection of wireless standards, the final form of a 4G device will constitute various standards.
A telecommunications network is telecommunications links connecting nodes that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals.
Inter-system routing policy (ISRP) – network selection rules for a UE with potentially more than one active access network connection (e.g., both LTE and Wi-Fi). Such UE may employ IP flow mobility (IFOM) , multiple-access PDN connectivity (MAPCON) or non-seamless Wi-Fi offload according to operator policy and user preferences.
This can be a local WAN connection. Cell phones communicating with a single cell tower constitute a local subnetwork; the connection between the cell tower and the rest of the world begins with a backhaul link to the core of the internet service provider's network (via a point of presence). A backhaul may include wired, fiber optic and wireless ...
IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
The Intelligent Network (IN) is the standard network architecture specified in the ITU-T Q.1200 series recommendations. [1] It is intended for fixed as well as mobile telecom networks.
In March 2010, Huawei achieved what it stated is a world-record 1.2 Gbit/s download speed on a demo network built around Huawei's prototype SingleRAN LTE-Advanced device. [13] In November that year, the company released a new SingleRAN technology, enabling operators to migrate between WiMAX and LTE TDD networks. [ 14 ]
