TOP LOC 222023 LTE – Long Term Evolution

Welcome to the comprehensive course on "LTE Technologies: Architectures, Advancements, and Emerging Trends" offered in cooperation with the Medipol University in Istanbul /Turkey.

In the fast-paced world of wireless communication, Long-Term Evolution (LTE) has emerged as a cornerstone technology that powers our modern connectivity. From its origins as a groundbreaking fourth generation (4G) standard to its continual evolution and influence on future networks, this course will dive deep into the intricate realm of LTE technologies. Throughout this course, we will embark on an exploration of LTE's journey, from its inception to its transformative impact on wireless communication. We will dissect the underpinnings of LTE, unraveling the mechanics behind its Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO) fundamentals. Our journey will take us through the physical and network architectures of LTE, enabling us to understand the core components that enable its exceptional performance.
