| (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: |
| (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. |
