Electronic Communications Act, 2005 (Act No. 36 of 2005)ICASANotice regarding Final Radio Frequency Assignment Plans for the Frequency Band 406.1 to 410 MHz in terms of Regulation 3 of the Radio Frequency Spectrum Regulations, 2015AppendicesAppendix B |
Appendix B
Interference Resolution Process
Technical procedures related to bilateral and multilateral cross-border frequency coordination agreements for 4 geographical sub-regions are defined by the African Union, which includes the Southern African sub-region of 10 countries. Cross-Border Frequency Coordination and interference resolution should follow the Harmonized Calculation Method for Africa (HIPPSA)21 and (HCM4A)22 or any appropriate methods applicable.
When requesting coordination, the relevant characteristics of the base station and code or PCI group number should be forwarded to the Administration affected. All of the following characteristics should be included:
| a) | carrier frequency (MHz). |
| b) | name of transmitter station; |
| c) | country of location of transmitter station; |
| d) | geographical coordinates (latitude, longitude); |
| e) | effective antenna height (m); |
| f) | antenna polarisation; |
| g) | antenna azimuth (degrees); |
| h) | antenna gain (dBi); |
| i) | effective radiated power (dBW); |
| j) | expected coverage zone or radius (km); |
| k) | date of entry into service (month, year); |
| l) | code group number used; and |
| m) | antenna tilt (degrees). |
The Administration affected shall evaluate the request for coordination and shall within 30 days notify the result of the evaluation to the Administration requesting coordination. If in the course of the coordination procedure the Administration affected requires additional information, it may request such information.
If in the course of the coordination procedure, an Administration may request additional information.
If no reply is received by the Administration requesting coordination within 30 days, it may send a reminder to the Administration affected. An Administration not having responded within 30 days following communication of the reminder shall be deemed to have given its consent and the code co-ordination may be put into use with the characteristics given in the request for coordination.
The periods mentioned above may be extended by common consent.
