This e-learning course is designed for those who are, or intend to be, involved in planning, commissioning or maintaining LTE (Long Term Evolution) mobile systems.
This course introduces the features, structure and operation of the radio access network and evolved packet core of a LTE (Long Term Evolution) mobile system.
The course begins by describing the evolution of 3GPP mobile systems to an all IP environment and summarising the methods introduced to improve the capabilities of those systems. The aim of, and progress in, the Long Term Evolution (LTE) of mobile systems is then discussed. The functions of the elements of the LTE radio access network and the Evolved Packet Core are described and compared to the similar functions of earlier dual circuit-/packet-switched systems.
The remainder of this course then focuses on the LTE radio access network (RAN): the choice of frequency bands for LTE operation is discussed, the principles and advantages of OFMDA described and the radio access technology processing employed in an LTE RAN explained.
You will get the most out of this online LTE course if you already have an understanding of the principles of mobile communications. Therefore, familiarity with the material in the courses MBA: “Introduction to mobile systems” and MBB: “Mobile radio communications” is desirable.
This e-learning course has a comprehensive range of interactive training facilities to provide a total learning experience. Technical words and acronyms have links to an online glossary giving an instant explanation. Interactive simulations explain concepts and systems operation.
Onscreen question sessions at the end of each module test understanding and provide further guidance and instruction. Revision links provide quick access to subjects previously discussed and relevant to the module being studied. Once studied as a structured, assessed course, the content can be browsed for revision or reference.
By the end of this course you will be able to:
- explain the need for mobile systems with capabilities beyond those of 3G and the work of 3GPP to standardise systems to meet those needs.
- explain the development of core network structures through HSPA+ to System Architecture Evolution (SAE).
- describe the role of the functional components of the LTE radio access network and the Evolved Packet Core.
- describe LTE standards for the downlink and uplink of the air interface and explain why different technologies have been chosen.
- describe the principles and spectral efficiency advantage of OFDM.
- describe the role of an IP Multimedia Subsystem (IMS) with reference to the evolution of mobile systems to an ‘All IP’ environment.
- explain considerations applying to frequency allocations for LTE.
- describe the use of carrier aggregation to increase data transfer rates.
- describe the techniques used in the LTE radio access network to maximise data transfer rates in the presence of noise and interference with reference to MIMO, Hybrid ARQ and Adaptive Modulation and Coding.
