LTE Air Interface Operation

With the introduction of LTE came the development of a new radio technology based on OFDMA / SC-FDMA. This course focuses on the LTE Air interface and provides a detailed analysis of the structure and features of the physical layer, as well as the layer 2 and 3 protocols, before explaining how these are used in the operation of the radio link from initial attach, through service delivery and mobility. Finally, the concept and operation of LTE-M and NB-IoT are detailed.
