Course status:
  • The course is lectured every academic year in the spring term. 
  • Intended for fourth year students. 
  • The course can be included as a compulsory course in the major/minor subject
    • Communication Systems and as optional course in the major/minor subjects
    • Radio Engineering, 
    • Signal Processing for Communications
    • Teletraffic Theory.
  • Included in the curriculum of the International Master’s Program in Telecommunications.
Course targets:
The course gives basic knowledge about radio network planning with the focus on cellular radio network planning. This knowledge is needed by radio network planners employed by system manufacturers, operators or other parties in the mobile communications area. After the course the participant will understand and be able to apply in his own work:
  • the objectives and general outline of radio network planning,
  • the radio link budget and its application to BS design to meet coverage targets,
  • traffic estimation and its application to cell design to meet capacity targets,
  • interference analysis and its application to frequency allocation to meet interference outage targets in FDMA/TDMA based radio networks,
  • relationship between capacity and coverage especially in CDMA networks.
Prerequisites:
It is assumed that the participants have done S-72.245 Transmission Methods in Telecommunication Systems or S-72.420 Design Metho-dology in Telecommunication Systems (3 credits) or equivalent courses and S-72.610 Mobile Communication Systems and Services (2 credits).

Teachers:
Professor Sven-Gustav Häggman is the responsible teacher of this course. 

Lectures and exercises:

  • Lectures are held on Wednesdays 10 – 12 a.m in Auditorium S3, and on Thursdays 10 – 12 a.m. in Room I256.
  • Separate exercises hours are not held, but typical problems and their solutions are shown interleaved with the lectures.
Assignment:
The course includes a compulsory assignment where the described planning methods are applied to the preliminary design of a GSM1800 radio network for a fictive service area. The assignment is done in two persons’ teams.

The plan comprises a capacity plan, a coverage plan, and a frequency plan, which are done like in the lecture example (which is not GSM). The plan is based on the use of macrocells in all regions, but in the city region a separate macrocell plan for vehicular originated traffic and microcell plan for pedestrian originated traffic are implemented. The target is to first estimate the offered traffic and then minimize the number of cells, and then to minimize the number of transceivers in each cell still fulfilling the blocking and interference outage targets for this traffic, given the maximum parameter values. Network tuning and easy network expandability are not considered.

The purpose of this exercise is to help the student to understand how different things interact in cellular radio network planning, and, hopefully, to give the student skills to design computer planning tools. It corresponds mainly to the initial network dimensioning to get a rough cost estimate when a vendor should offer a network. Final network planning should be  made with computer tools and may be based on other objectives than minimising excess capacity as in this assignment.

To facilitate the work some unsupported Excel-tools for radio link budget and minimum reuse distance calculations are provided.

Requirements:

  • The course is carried out by
    • an exam and
    • an assignment.
  • The exam requirements consist of the material distributed to the students.
  • The first exam is on May 10, 2005, the next exams are in August/September 2005 and in February 2006.
  • The exam consist of two parts: starting with a closed book part comprising two tasks about general topics followed by an open book part comprising three problem solving tasks.

Final grade: 
The final course grade is calculated from the formula:

Final grade =  (Exam grade  +  assignment grade)/2

The student should pass both the exam and assignment with an accepted grade.
