If you are looking for a Long Term Evolution (LTE) power point (ppt) to answer your questions, look no further. Understanding how the LTE architecture works is no easy task.There are many variables and channels, and an LTE architecture ppt helps put it all together. In Long Term Evolution (LTE), a Microsoft Power Point presentation authored by Abhijit Kaul, Nitin Khanna, Sahana Mallya and Vaibhav Malik, the technical architecture is explained in a way that’s easy to comprehend. Malik describes LTE as a network made up of the following:
- OFDM (Orthogonal Frequency Division Multiplexing) for downlink
- SC-FDMA (Single Carrier – Frequency Division Multiple Access) for uplink
- MIMO (Multiple Input Multiple Output)
- SAE (System Architecture Evolution)
LTE network elements include:
- –  Supports air interface
- –  Provides radio resource management function
Serving Gateway (SGW)
- –  Provides Mobility
- –  Responsible for Routing and Forwarding
Packet Data Network Gateway (PDN GW)
- –  Provides connectivity to Internet
- –  Provides QoS and mobility between 3G and non-3G networks
Mobility Management Entity (MME)
- –  Manages mobility and provides security
- –  Operates in control plane and provides authentication
