LTE Air Interface

LTE Air Interface

This training course on the LTE Air Interface or radio Interface covers all the main aspects of this area of LTE in an approachable manner that all will be able understand whether technical or not too technical.

The LTE Air Interface course reviews the LTE system architecture to provide the context within which the air interface operates and to provide a background for the required protocols. This section also covers the issues related to spectrum and deployment of LTE networks. A comparison of the LTE Air Interface is also made to WiMAX, comparing the different advantages of the systems

The LTE Air Interface course covers the central scheme of OFDM / OFDMA / SC-FDMA for modulation and multiplexing along with the advantages it provides.

Layer 2 of the LTE protocol stack is also covered detailing the three sub-layers, namely MAC, RLC and PDCP. In addition to this the RRC control protocol is also covered. In each case the main elements of the protocols is explained, showing how each relates to issues of mobility and mobility management with example of typical procedures given. Architectural and operational aspects of the Multicast Broadcast Multimedia Service are also covered.
