Objective: "How to integrate radio into a connected object"
The objective of this course is to know and understand the principles, fundamental issues and architectures of modern radio transmission systems in order to be able to specify and deploy connected objects in Internet ecosystems such as Objects, Wireless Sensor Networks, M2M, Cyber-Physical Systems.
For this we will study in class, in TD and TP:
1. telecommunication electronics, in particular front-end analogue devices: modems, amplifiers, filters, antennas,
2. high-performance radio protocols for connected objects (beyond WiFi and Bluetooth), in particular protocols in harsh environments and long-distance and ultra-low-power protocols, 3. Radio regulations and standards
4. front-end radio design techniques: antenna and impedance matching, noise reduction techniques and power amplifiers,
5. techniques for extending the lifetime of connected objects - IoT Hardware Device Extension Lifetime. This part is the synthesis of UPs 1 to 3
