Radio Frequency Spectrum
Can be defined as the entire spectrum of electromagnetic frequencies used for communications; includes regulated frequencies used for radio, radar and television and ranges from about 3 KHz to about 300 GHz
The radio frequency spectrum is a limited natural resource and must be used rationally, efficiently and economically, so that countries and groups of countries may have equitable access to it. Radio waves propagate in space with no regard for political frontiers
Radio Spectrum Management
Frequency spectrum management can be defined as various administrative and technical procedures that are intended to ensure the operation of radio stations of different radio communication services at any given time without causing or receiving harmful interference. It takes place at two levels: national and international.
Spectrum Management unit
The radio frequency spectrum management is one of the technical units in POTRAZ, within the Technical Services department. The unit is made up of three main sections;
- Frequency management and planning
- Frequency Spectrum monitoring
The mission of the radio frequency Spectrum Management Unit is to ensure and encourage efficient and minimum interference use of the radio frequency spectrum in Zimbabwe.
The Department’s functions are:
- National Spectrum Planning, allocation and allotment
- Spectrum Assignment
- Spectrum User Licensing
- Spectrum Control (Usage Monitoring, Engineering Analysis)
- Enforcement (Inspections and investigations)
- Radio Dealership Licensing
- Administrative and Legal Issues
- Develop Spectrum Policies, Terms and Conditions for Accessing Spectrum and enforce the same.
- Radio Equipment Type Approval
- International coordination
- International Representation
- Spectrum Standards Development, adoption and maintenance.
- To prepare and regularly review and update the radio frequency spectrum plan for Zimbabwe in line ITU-R Allocation Table and regional radio frequency plans.
- To identify bands with major frequency demand and plan accordingly.
- To monitor technological developments and ensure the radio frequency plan can accommodate the developments.
- To monitor and ensure efficient and equitable use of the radio frequency spectrum.
- To investigate and resolve all cases of harmful interference on a local, regional and global scale so that radio services and stations coexist compatibly, and thus providing economic benefit to the country‘s infrastructure through access to interference – free, accessible telecommunications services.
- Ensure acceptable quality of radio and television reception by the general public.
- Detect and identify illegal use of the valuable and scarce spectrum resource.
