This course provides an interactive hands-on introduction to the exciting world of radio communications. The course is wide ranging, covering basic signal properties, radio spectrum and management, transmission and reception, antenna and feeder design, modulation techniques, multiplexing techniques, and a brief description of different radio technologies. The course includes elements covering basic electronic and mathematical principles.
- Characterize the radio spectrum in terms of its system applicability and management.
- Estimate radio link budgets using logarithmic units.
- Outline the key of modulation and develop these to explain advanced digital modulation schemes.
- List and explain the function of key blocks of different types of radio transmitters and receivers.
- Describe transmission line characteristics and explain how they are used in radio systems.
- Characterize antenna performance in terms of gain, beam-width, bandwidth and front-to-back ratio.
New entrants, current and aspiring telecom professionals, including IT staff, corporate decision-makers, consultants and students will find this course valuable.
