Notice 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, 2015

3. General

 

3.1 Technical characteristics of the equipment used in Single Frequency Links (Fixed Services), Mobile Services and IMT Satellite shall conform to all applicable South African standards, international standards, International Telecommunications Union (ITU) and its radio regulations as agreed and adopted by South Africa

 

3.2        All installations must comply with safety rules as specified in applicable standards.

 

3.3 The equipment used shall be certified under South African law and regulations.

 

3.4 The allocation of this frequency band and the information in this Radio Frequency Spectrum Assignment Plan (RFSAP) are subject to review.

 

3.5 Frequency bands assigned for the IMT Satellite component include bands 1518 – 1525 MHz.

 

3.6 Frequency bands assigned for Single Frequency Links include bands 1517 – 1525 MHz.

 

3.7 WRC-03 and WRC-07 allocated this additional spectrum to the mobile satellite service to complement existing L-band allocations used by numerous satellite operators. Therefore, the band 1518 – 1525 MHz is sometimes called “Extended L band” for MSS, referring to satellite user terminals operating in the band 1518 to 1525 MHz (space to Earth), with the terminals transmitting to the satellite in the band 1670 MHz to 1675 MHz (Earth to space). In general, the wider band 1518 - 1559 MHz band is used by several GSO MSS operators, including Inmarsat, to provide vital communication services to ships, aircraft, and land mobile users.

 

3.8 This Satellite component of IMT is applicable for the provision of the satellite service. The typical technical and operational characteristics identified as appropriate by the ITU are described in the following documents

 

This band is identified as being available for the satellite component of IMT, and some of the services offered by MSS operators form part of the “satellite component for IMT-2000”, as defined by Recommendation ITU-R M. 1850-2 (https://www.itu.int/rec/R-REC-M.1850 );
ITU-R Recommendation M.1391: Methodology for the calculation of IMT-2000 satellite spectrum requirements (https://www.itu.int/rec/R-REC-M.1391/en );
ITU-R Recommendation M.1167: Framework for the satellite component of International Mobile Telecommunications-2000 (IMT-2000) (https://www.itu.int/rec/R-REC-M.1167 ); and
ITU-R Recommendation M.818 - Satellite operation within International Mobile Telecommunications-2000 (IMT-2000) ( https://www.itu.int/rec/R-REC-M.818/en )

 

3.9 Single Frequency Links (in the Fixed Service) are applicable for the provision of the system and service. The typical technical and operational characteristics identified as appropriate by the ITU are described in the following documents

 

CEPT Recommendation T/R 13-01 E (Preferred channel arrangements for fixed service systems operating in the frequency range 1 - 2.3 GHz (https://docdb.cept.org/download/2499 )
ITU-R Recommendation F.1242: Radio-frequency channel arrangements for digital radio systems operating in the range 1 350 MHz to 1 530 MHz (https://www.itu.int/rec/R-REC-F.1242/en )

 

3.10 The following reports provide the details of co-existence studies between Mobile and MSS services in this band.

 

ECC Report 263 6 (Mar 2017) addressed the compatibility studies between IMT base stations operating below 1518 MHz and MSS land terminals operating above 1518 MHz.
This led to the following balanced approach published in ECC decision (17)06 7 and EC decision 2018/661/EU 8.
ECC/DEC/ (04)09 amended 26 June 2009: ECC Decision of 12 November 2004 on the designation of the bands 1518 - 1525 MHz and 1670 - 1675 MHz for the Mobile-Satellite Service 9.

 

3.11 The use of the band 1518 - 1525 MHz by the mobile-satellite service is subject to coordination. According to the Radio Regulations, the mobile-satellite service operating in the band 1518-1525 MHz stations shall not claim protection from the stations in the fixed service10.
