TECHNOLOGY FOCUS
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.
COURSE CONTENT
This elearning course gives participants the knowledge of rules and regulations for the utilisation of the Radio Spectrum.
Methods for analysis, planning and coordination of radio systems in order to achieve required performance within the system are discussed, as well as precautions to avoid interfering with collocated radio systems.
International and national bodies and regulations are presented. International agreements for coordination are discussed.
Course 604 Introduction, organisations and regulations
- Introduction, organisations and regulations
- Radio Regulations
- Spectrum Monitoring
Course 605: Technicals Basics
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.
- Technical characteristics, radio noise
- Radio wave propagation
- Collocation Interference
Course 606 - Radio Spectrum Management for Various Services
Methods for planning and coordination of point-to-point, point-to-multipoint and area covering radio networks to achieve performance targets and spectral efficiency are covered. The following services are covered:
- Space services
- Mobile services
- Broadcasting services
- Radionavigation, Radiolocation, Science services
- Non-licensed services, other issues
Recommended course order is
1. 604 - Introduction, organisations and regulations
2. 605 - Technical basics
3. 606 - Spectrum Management for various services.
Students with no need for knowledge in the administrative work in spectrum management may select only (2) and (3).
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.
The videos can be found here:
