Radio Propagation in Wireless Networks


  • The exam results were given on 22.12.2017. The exam results didn't include bonus points. The final course mark includes also possible bonus points. If you haven't received your credit points make sure you have already passed the project work and given feedback through KAIKU system. (updated 2.1.2018)
  • One general hint for the project work in case you are struggling with it. In assignment task 4 you are NOT comparing the E-field strength (which is normally given as a density, V/m) with the other models, i.e. the solution you get from first task to these other models. Find the "plane earth loss" model and utilize that in task 4. (updated 5.12.2017)
  • No more lectures in the course! Please remember to sign up for the exam! (updated 4.12.2017)
  • Please note! The exact version for calculating the 'Ev' and 'Eh' was incorrect in the project work slide 8 (as well as in lecture slides). If you have used the approximation (calculation with 'E0'), you don't have this problem. Now the correct versions are available in the project work slides as well as in lecture slides. Sorry for the inconvenience! (updated 27.11.2017)
  • Please note! There was initially a small typo in the project work / lecture slides. The 'k0' in the given equations should be 'k'. (updated 23.11.2017)
  • The mandatory project work of the course has been published. See more info from the Project work section. (updated 13.11.2017)
  • The order of the contents changed for the last lectures. The mandatory course project work will be published this week. (updated 13.11.2017)
  • First exercise tasks now available. (updated 31.10.2017)
  • Correct exam dates updated (see below). (updated 30.10.2017)
  • NOTICE! The exercises will start 3.11.2017 (i.e. not in the first week of period II). (updated 19.10.2017)
  • The course will be organized in period II on the 2017-2018 academic year. Lectures will start 23.10.2017. (updated 7.6.2017)

Course objectives

  • The goal of the course is to familiarize students to radio signal propagation mechanisms and to the characteristics of mobile radio channels, which both are needed in the designing of modern wireless communication systems and networks.

Contents of the course

  • Radio propagation mechanisms
  • Propagation loss prediction models
  • Mobile radio channel: slow and fast fading
  • Atmospheric effects and satellite mobile radio channels
  • Spatial radio channels

Time and Place

  • Lectures: Mondays 13–16 in TB219 during the II period.
  • Exercises: Fridays 8–11 in RG100C (Group 1) or Fridays 13–16 in RG100C (Group 2).
  • Lectured in English.
