Satellite Spectrum protection 11
12 Protection of Satellite Spectrum in Support of Growth and Innovation Three categories of ITU WRC-19 Agenda Items require the attention of African countries: Defend Existing Satellite Spectrum Study Regulatory Flexibility Obtain Satellite Spectrum AI 1.14: HAPS AI 1.13: New spectrum for IMT/5G AI 1.16: More C-and spectrum for RLAN AI 1.4: Review Ku-band (BSS) orbital position restrictions AI 1.5: ESIMs in Ka-band AI 1.6: NGSOs in Q/V bands AI 7: Coordination procedures AI 9.1.3: NGSOs in C band AI 9.1.7: Unlicensed VSATs AI 9.1.9: More FSS spectrum
13 Role of Satellite Systems in 5G Ecosystem IMT/ 5G should NOT be about mobile technology only it is more than just Cellular it is Wireless Satellite providing Backhaul services 5G is an end-to-end ecosystem of different technologies. Satellites provide unmatched coverage and reliability; Satellites today can deliver data rate of > 100 Mbits/s 1 Gbit/s in broadcast / multi-cast mode; By 2020-2025, satellite systems can deliver > 1 10 Gbit/s services and will require certainty and viability in spectrum access.
14 ITU WRC 2019 Challenges WRC19 preparation present an unprecedented level of complexity from the start and requires coordination with Key organisations Some of these challenges include: Unilateral decision by Member States on satellite spectrum bands that are outside the scope of the WRC-19 agenda (e.g. C-band, Ka-band); Interest by various stakeholders in same frequency bands (including satellite bands) under different Agenda Items (e.g. AI 1.13 and AI 1.14); Timeline for technical studies are stretched increasing uncertainty on possible results. The Political Agenda Influence from the start: ITU under pressure to design compromises; Political process should not be a substitute to a technical process to drive decisions on spectrum and become the reference for spectrum global harmonization.
15 WRC 15 C-Band Outcome Identification of additional frequency bands for IMT Outcome: - 3400-3600 MHz has a nearly global identification for IMT - 3600-3700 MHz identified for IMT in 4 countries in Region 2 only - 3700-4200 MHz is preserved for FSS on a global basis - In Region 1, mobile service remains secondary in the band 3600-4200 MHz There remains significant uncertainty whether IMT community requires such additional spectrum The best practices for efficient spectrum allocation is based on two main principles: International harmonization as a key for the success of future IMT systems roll out The need to ensure incumbent services are not displaced and allowed to expand their services in the future WRC-15 confirmed that there is little interest in the 3600-4200 MHz band for IMT
16 Global map of IMT Identification in 3400-3600 MHz The ATU/ EACO is following ITU study cycle and its remit High usage and future growth of FSS C-band usage 3600 4200 MHz is over Africa 3400 3600 MHz IMT Identification 3400 3700 MHz IMT Identification 3500 3600 MHz IMT Identification No IMT Identification 3400 3700 MHz
17 Why C-Band Remains a Mainstay? C-band beams can cover large geographic areas, and facilitate intercontinental and global communications Due to broad reach, C-band allows for economically viable coverage of smaller markets and low density regions C-band can provide region-wide coverage at high availabilities, irrespective of rain zones Intelsat Epic NG satellites use C-band in multi-spot configuration C-band has unique propagation and coverage characteristics that cannot be replicated in other frequency bands Intelsat 901 @ 342 E The low atmospheric absorption in these bands enables highly reliable space-to-earth communication links with wide service coverage, particularly in, but not limited to, geographical areas with severe rain fade conditions
