The main objective of the course is to provide a comprehensive and state of the art knowledge in the area of mobile communication. The course emphasis is on the structure and function of the complete system. A detailed study of the subsystems that comprises the overall system is carried out. The technical knowledge provided in the course on different aspects of the system will help the participant in understanding the functioning of the system. This will further help in providing the necessary expertise required by the industry.
