Course name: LTE Basics
Duration: 1 Day
Requirements: Fundamentals of wireless communication.
Overview: Third Generation HSPA and HSPA+ systems have gained huge popularity among the subscribers along the years. The popularity of these systems is predicted to increse almost exponentally in the coming years. Existing HSPA the systems have met and are still meeting the evergrowing challenges and requirements quite well. However, to take the next step in the wireless cellular communication the specification of a new All-IP based systems was released officially in 2008. Now these Long Term Evolution (LTE) systems are starting to emerge in commercial use as well. The purpose of this course is to cover basics of LTE, successor of HSPA systems, also referred as 3.9G or 4G.
Objective: After the course the trainees will have general level understanding of the fundamentals related to LTE. This includes deployment and specification status; evolved LTE architecture, protocols, layers and channels, radio resource management, VoIP solutions and many more.
