Radio Spectrum Management is of ever increasing importance for Telecommunications Companies, Public Authorities as well as for Defense Forces.
It is necessary for the planning, implementation and operation phases of various types of technologies: point-to-point/multipoint links, broadband wireless access, cellular systems, radar, navigation systems as well as television and sound broadcasting networks, both analogue and digital.
The hierarchical process of military spectrum management has extensive needs for long-term strategic as well as short-term tactical frequency management.
This elearning course gives participants the knowledge of Technical basics of the Radio Spectrum Management.
Central subjects include coverage, availability and interference issues in Radio Spectrum Management.
An overview of radio wave propagation and characteristic radio system properties in different frequency ranges is presented. Radio wave propagation causing over-range and interference is discussed.
The course has 3 parts;
- Technical characteristics, Radio noise
- Radio wave propagation
- Collocation Interference
When the Radio Spectrum Management course is conducted as classroom training the WRAP software for spectrum management and radio network planning is installed on the student computers and practical exercises are performed. The software is available for E-learning students also although the E-learning course does not make use of do-it-yourself exercises. Computer requirements are PC, Windows Vista, 7 SP1, 8 and 10.
Videos demonstrating the use of the software can be downloaded at the same FTP site, folder Videos.
