Electronic Communications Act, 2005 (Act No. 36 of 2005)ICASANotice regarding Final Radio Frequency Assignment Plans for the IMT3300 Band in terms of Regulation 3 of the Radio Frequency Spectrum Regulations, 20155. Requirements for the usage of the radio frequency spectrum |
| 5.1 | This chapter covers the minimum key characteristics considered necessary in order to make the best use of the available frequencies. |
| 5.2 | The use of the IMT3300 band is limited to IMT services. |
| 5.3 | Only systems using digital technologies that promote spectral efficiency will be issued with an assignment. Capacity-enhancing digital techniques are being rapidly developed together with techniques that promote efficient spectrum use without reducing service quality. These techniques are encouraged. |
| 5.4 | In some cases, a radio system conforming to the requirements of this RFSAP may require modifications if harmful interference is caused to other radio stations or systems. |
| 5.5 | The allocation of spectrum and shared services within this band are found in the National Radio Frequency Plan (NRFP) and an extract of the NRFP is shown in Appendix A. |
| 5.6 | Maximum radiated power: |
| 5.6.1 | The conservative in-block base station power limit is 68 dBm/ (5 MHz) EIRP. |
| 5.6.2 | The Authority acknowledges the feedback from the consultation that it should include a Total Radiated Power (TRP) limit for AAS base stations into the assignment plans. Stakeholders noted that this inclusion would bring South Africa in line with global industry development, and that if it is not done, the restrictive nature of the regulations will inevitably have a detrimental effect on the quality of service that can be expected from radio networks. TRP specifications are only allowed for and provided for mobile stations. |
| 5.6.3 | Mobile Station transmissions should not exceed 23 dBm EIRP. |
| 5.6.4 | Mobile Station transmissions should not exceed 25 dBm TRP. |
| 5.6.5 | On a case-to-case basis, higher EIRP may be permitted if acceptable technical justification is provided. |
| 5.6.6 | Where appropriate, subscriber terminal stations should comply with the technical specification outlined under the latest version of 3GPP specifications, e.g., TS 36.521-1 for LTE, 38.521-1 for 5G New Radio (NR). |
| 5.6.7 | ICNIRP Guideline compliance is required, where applicable; and |
| 5.6.8 | Criteria and guideline for interference mitigation are described in Appendix D. |
