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. |
