Goal(s)

Understand the issues specific to the physical layer of wireless networks. The first part offers an overview of mobile radio wireless channels (specificities - multiple paths, Doppler effect -, channel classes, types of problems and remedies). The second part gives practical examples of current radio technologies (ultra high bandwidth solutions, and ultra low consumption low bandwidth solutions).

Content(s)

Part I (prof Laurent ROS): Radio-mobile wireless communication channels
I1 - Specificity and Modeling of mobile radio communication channels (multipath propagation, complex baseband equivalent, Coherence Bandwidth and Cohence Time, Rayleigh and Rice variation model, Doppler Spectrum, etc.)
I.2 - Principle of transmit/receiver schemes for certain problems (Diversity techniques - for Rayleigh “flat fading” channels, OFDM multi-carrier modulation - for frequency selective channels-).

Part II (by Michel AYRAUD, senior engineer at STMicroelctonic): WLAN AND INTERNET OF THINGS: sUltra High Speed ??Wireless and Ultra Low Consumption Solutions

II.1 Introduction (Wireless, Radio basics: Link budget, LOS/NLOS range, Link capacity, Bandwidth and sensitivity, MIMO, modulations, Usable frequency ranges -Millimetric , From WiFi to GiFi-)
II.2 Structure of integrable receivers (Direct detection: gain/bandwidth problem, heterodyne frequency change, super heterodyne frequency change, Other possibilities, electronic antenna scanning, UWB), Practical example: ST solutions at 60GHz)
II.3 SOLUTIONS FOR IoT

  • The Bluethooth Low Energy standard (Main applications, Main characteristics, Practical solution: BlueNRG-MS and STM32WB from STm)
  • SIGFOX long distance communications (Main applications, Main characteristics, Practical solution: S2_LP from STm)
