Frequently Asked Questions (FAQ)
- Television white spaces (TVWS): These are interleaved or contiguous vacant/unused spectrum between broadcast TV bands.
- Primary User (PU): This is a licensed incumbent operator of a given radio frequency (RF) spectrum band.
- Secondary User (SU): This is an unlicensed operator in a given radio frequency (RF) spectrum band.
- White Space Device (WSD): This is radio communication equipment designed to operate in the TVWS, mostly as a SU.
- Geo-location Spectrum Database (GLSDB): This is a geographical-based complex system designed to identify and dynamically allocate TVWS to the SUs without causing harmful interference to the PU. The relevant national spectrum regulatory authority must approve operations of this system
- Very High Frequency (VHF) band: In the South African television spectrum allocations this band is found between 174-238/246-254 MHz frequency ranges.
- Ultra High Frequency (UHF) band: In the South African television spectrum allocations this band is found between 470-578 MHz/582-862 MHz frequency ranges.
- Dynamic Spectrum Access (DSA): This describes advanced techniques used by intelligent and agile radio devices
to utilise spectrum, in space (Geo-location), frequency, or time dimensions.
