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 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.

Download the file WRAPv 4_21_3_0_Demo 32-bit.zip (or newer version if available), unzip and follow the Setup instructions document. You may also download the Videos folder to watch demonstrations on how to use the software.

 

WHO SHOULD ATTEND

The course is intended for engineers and radio spectrum managers working with radio communications with a need to know about regulations for the utilisation of the radio spectrum and methods for analysis, planning and coordination of radio systems in order to achieve required performance within the system without interfering with other radio systems.
