Duration: 5 days

Due to the fast growing GSM-network systems, the efficient basic planning process continues to have an important role. For existing GSM network systems which are influenced by changing and increasing usage, the continuous optimisation is an additional permanent challenge.

Accordingly, in addition to the introduction to the basics of radio network planning and its system and hardware dependencies, this course offers in a supplementary chapter with detailed possibilities for network optimisation. Subjects such as planning and optimisation of coverage, capacity, allocation of frequencies and network IDS will be explained.

After the course the participants will know about and understand the background of radio network planning. The participant will be able to make sound decisions for the possible usage of software tools. This course teaches knowledge and techniques which are relevant for planning and are independent of particular planning tools.

Target Group / Requirements

This course addresses employees in the area of radio-network planning and optimisation who have sound basic knowledge of GSM.
