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.
