Electronic Communications Act, 2005 (Act No. 36 of 2005)ICASANotice regarding Final Radio Frequency Assignment Plans for the Frequency Band 138 to 144 MHz in terms of Regulation 3 of the Radio Frequency Spectrum Regulations, 20155. Requirements for usage of 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 138 - 144 MHz band is for Fixed and Mobile Services and is limited to single frequency alarms and other single frequency and dual frequency links as well as remote control apparatus |
| 5.3 | Capacity enhancing digital techniques are common and such techniques that promote efficient use of spectrum, without reducing quality of service are encouraged. Only systems using digital technologies that promote spectral efficiency will be issued with an assignment. |
| 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 these bands 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 | Base Station transmissions should not exceed 44.8 dBm / 5 MHz EIRP. |
| 5.6.2 | Mobile Station transmissions should not exceed 38.8 dBm EIRP. |
| 5.6.3 | On a case to case basis, higher EIRP may be permitted if acceptable technical justification is provided. |
| 5.7 | ICNIRP15 Guideline16 compliance is required, where applicable; |
| 5.8 | Criteria and guidelines for interference mitigation are described in Appendix B. |
