IoT Protocols and CommunicationsLaajuus (5 cr)

Objective

After completing the course the student:
- understands basic signal presentations in time and frequency domain and how they are related in real signals used in different IoT communication systems
- can show signal spectrum with basic signals and understands the need and principle of filtering
- understands different methods (FDM, TDM, CDM) in signal transferring and modulation principle and is familiar with different ways of transferring signals in modern wireless communication systems
- understand phasor representation and can sketch constellation chart
- understands sampling principals and limitations with digital signals
- understands noise behaviour and its influence to link budjet
- is familiar with typical protocols used in IoT systems
- is familiar with basic measurement equipment
