212 No. 42829 GOVERNMENT GAZETTE, 8 NOVEMBER 2019 x potential channelisation of IMT750 will be decided at WRC-15 and based on WP5D recommendation. ? Option 1 (ITU Region 3) offers a larger ecosystem currently, but ITU Region 3 equipment could also be used in ITU Region 1, at least within the 30 MHz international roaming band. ? In addition, Option 1 (ITU Region 3) would offer 2×10 MHz instead of 2×5 MHz in IMT850 only if there is no implementation of GSM-R, but this is not the case for South Africa. Therefore, in this context, the Option 2 and 3 (ITU Region 1) solutions are more advantageous. CDMA and GSM-R ? Liquid Telecom’s assignment in IMT850 was 827-832 // 872-877 MHz and overlapping to the GSM-R assignment from 876-880MHz // 921-925 MHz. Liquid Telecom has to ensure the migration to 825-830 // 870-875 MHz, which is 1 MHz next to the GSM-R band; therefore, the IMT850 licensees need to implement interference mitigation measures (e.g. filters) in areas with GSM-R sites. ? GSM-R is currently deployed by PRASA and it is expected that GSM-R will also have a long-term usage. The next possible migration step might be from GSM-R in 877.695- 880//921-925 MHz to LTE-R in IMT850 band. GSM-R investment might be optimised in the case of proper usage of SRAN equipment and further upgrades to LTE. 900 band ? The IMT900 migration from GSM to LTE should be possible in 2×5 MHz steps immediately. The additional demands of broadband IMT require spectrum harmonisation to allow licensees to have contiguous assignments. Consolidation will not be initiated until all operators have aligned to Phase 2 (Scenario 3) in order to carry out a one-step migration towards full IMT-usage with 2×5 MHz bands. ? Current guard bands have to be reduced between the operators on mutual agreement to improve spectral efficiency. 1800 and 2100 bands ? Potential migrations of GSM1800 or UMTS2100 bands to broadband IMT1800 or IMT2100 are possible and should be allowed based on operators capacity needs. ? IMT2100 extensions of TDD and FDD spectrum still need to be discussed and agreed at ITU level. Page 146 of 205
