Electronic Communications Act, 2005 (Act No. 36 of 2005)ICASANotice regarding Final Radio Frequency Assignment Plans for the Frequency Band 1518 to 1525 MHz in terms of Regulation 3 of the Radio Frequency Spectrum Regulations, 2015AppendicesAppendix B |
Appendix B - Interference Resolution Process
Many technical procedures related to bilateral and multilateral cross-border frequency coordination agreements for the four (4) geographical sub-regions are defined by the African Union which includes the Southern African sub-region of ten (10) countries. Whenever possible, cross-Border Frequency Coordination and interference resolution should follow the Harmonized Calculation Method for Africa (HCM4A) 32 .
When requesting coordination, the relevant characteristics of the base station and the 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 will evaluate the request for coordination and will, within thirty (30) days, notify the Administration requesting coordination the result of the evaluation. If, in the course of the coordination procedure, the Administration affected requires additional information, it may request such information.
If no reply is received by the Administration requesting coordination within (30) days, it may send a reminder to the Administration affected. Where the Administration fails to respond within thirty (30) days following communication of the reminder will be deemed to have given its consent, and the code coordination may be put into use with the characteristics given in the request for coordination.
The above-mentioned periods are subject to extension by common consent.
