Course Details
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.
Philip Nugent
Mpirical Trainer
Phil heads up Mpirical’s technical development, advising on the latest technologies and assisting the Mpirical team with his wealth of both historical and current knowledge. Phil’s specialist area is the mobile radio and RAN space, originally focussing on 2G and 3G technologies but more recently, heavily embedded with 5G New Radio for both Mpirical and customer specific projects.
