Regulations on the use of Television White Spaces, 2018

5. Avoidance of Harmful Interference

 

(1) The GLSD must provide Operational Parameters to ensure low probability of harmful interference to primary services caused by transmissions of WSD in compliance with:
(a) the ITU GE06 agreement2;
(b) the Astronomy Geographic Advantage (AGA) Act 21 of 20073 ;
(c) the National Radio Frequency Plan; and
(d) the Terrestrial Broadcasting Frequency Plan.

 

(2) Geo-location coordinates and geo-location uncertainty of Master WSD antenna must be determined automatically:
(a) using WSD internal geo-location capability prior to its initialisation with the secondary GLSD at a given location; and
(b) each time the device is activated from a power-off condition; or
(c) been relocated 100 m or more.

 

(3) If the Master WSD is located where its internal geo-location capability does not function, it may obtain its geo-location coordinates from a Type Approved external geo-location source that must be located within 100 m and securely connected to the Master WSD.

 

(4) Only Master WSD is permitted to communicate directly with the secondary GLSD for purposes of:
(a) Initialisation;
(b) registration;
(c) in requesting for Operational Parameters for itself; and
(d) on behalf of Client WSDs associated to it.

 

(5) Operations of WSDs are permitted only on channels and at power levels that are determined by the secondary GLSD as being available for each WSD.

 

(6) If the database indicates that the channel is no longer available at the current operating level:
(a) operation on a channel must cease immediately; or
(b) power must be reduced to a permissible level.
