LTE Technology Overview for Technical Audiences (Course W-LTE2)
Target Audience, Prerequisites, and Brief Description
This one day e-learning course (pre-recorded webinar) is aimed at technical audience involved in the design and deployment of LTE networks, equipment, or software.
We will start with the evolution of 3G UMTS to 4G/LTE. This will lead to a detailed discussion of all the major components of an LTE system and the motivations behind them. The operational and design goals and challenges of an OFDM-based LTE system are explained. Current LTE frequency bands, overview of radio access, MAC architecture, downlink and uplink channel structure, LTE network access, SAE, and LTE services will be discussed. Upon completion of this basic course, you will be well prepared to delve deeper into LTE through self-directed study or additional Eogogics courses on LTE.
