  1. LTE rollout: spectrum challenges By: Tariq Al Awadhi, EDSIA - Spectrum & IA Department

  2. Contents What is LTE? Global LTE landscape Spectrum bands and devices Spectrum fragmentation 700 and 800 band plans WRC-15 agenda items for IMT

  3. What is LTE? In 2004, 3GPP initiated project Long Term Evolution (LTE) to enhance the Universal Terrestrial Radio Access (UTRA) Targets: 3-4 times average throughput of Release 6 HSDPA levels in the Downlink (100Mbps), and 2-3 times HSUPA levels in the Uplink (50Mbps). Rel 8 of 3GPP (in 2008)– "E UTRA" – 1st Tech Std (36 series) of LTE All present LTE deployments adhere to Rel 8 standard Rel 10 of 3GPP now specifies LTE Advanced Ref: http://www.3gpp.org/LTE

  4. Why LTE? Drivers Description CostReduction • High Spectral Efficiency • Flexible/Scalable Bandwidth • Flat ALL-IP Network Infrastructure • Simplified SON • Faster Throughput • More High Speed Data Services • VoIP with High Capacity • Reduced Latency to Improve User Experience Innovation Evolution • One Global Standard for All Evolution Paths • Leverage of Existing 3G Infrastructure • Global Scale/Cheaper Terminals

  5. Global LTE deployments, trials & commitments 72 Commercial LTE launches in 37 countries 258 Commercial LTE commitments in 84 countries LTE Commercial Source: GSA-Evolution to LTE 8 May 2012 LTE Planned LTE Trial

  6. Spectrum bands for LTE & devices For 6 networks, 170 devices available due to large US market

  7. Spectrum fragmentation: Technical or legacy issue Model for Verizon: 4G LTE (700 MHz); CDMA EV-DO Rev. A (800, 1900 MHz); UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz) Model for AT&T: 4G LTE (700, 2100 MHz); UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz) In Australia, Apple website states: It is not compatible with current Australian 4G LTE networks and WiMAX networks.

  8. Band Plans for 700 and 800 Proposed band plan for GCC 703 733 758 788 791 821 832 862 880 915 925 960 Band plan considered by Asia 703 748 758 803 824 834 869 880 915 925 960 Band plan by FCC (USA) 698 806

  9. LTE launches in UAE • Etisalat has launched its LTE • Huawei dongle E398 is used which offers LTE, HSPA+ and UMTS • Etisalat using 2600 and 1800 MHz bands • Du is also in the final stages of launching LTE • Du using 1800 MHz band • TRA is working to make the 800 MHz band available after DSO • TRA is working with ASMG to harmonize 700 MHz band • 2 agenda items for next WRC (1.1 and 1.2)

  10. Agenda Item 1.1 (WRC-15) • Service • Mobile • Frequency Bands for additional allocation to MOBILE for IMT • TBD • Related regulatory provisions • TBD to consider additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) and related regulatory provisions, to facilitate the development of terrestrial mobile broadband applications, in accordance with Resolution233 [COM6/8] (WRC‑12);

  11. Agenda Item 1.2 (WRC-15) • Service (Region 1) • Mobile except aeronautical mobile • Related Frequency Band • 694-790 MHz • Related regulatory provisions • TBD to examine the results of ITU‑R studies, in accordance with Resolution 232 [COM5/10] (WRC‑12), on the use of the frequency band 694-790 MHz by the mobile, except aeronautical mobile, service in Region 1 and take the appropriate measures;

  12. Differences in the two agenda items

  13. Identify present usage status of bands identified for IMT Identify the total bandwidth allocated versus the required bandwidth based on Report ITU‑R M.2078, spectrum estimates Identify allocated and required bandwidth for the 3 frequency ranges: Below 1 GHz Between 1 GHz and 6 GHz Above 6 GHz Identify regulatory and technical challenges associated with bands for which sharing studies already completed in Reports ITU‑R M.2109, M.2110, M.2111, M.2112 Identify other potential candidate bands in the 3 frequency ranges where there is a deficit Undertake sharing studies for these identified potential bands Identify regulatory provisions Views on agenda 1.1 (WRC-15)

  14. Views on agenda 1.2 (WRC-15) Proposed channeling arrangement 800 Band 791 821 832 862 788 703 733 758 700 Band • 2 x 30 MHz as FDD allocation • Aligned (partially) with Region 3 • Offers maximum spectrum for IMT as both 800 and 700 bands can be used • Countries can plan for Digital Dividend 1 (800 band) and / or Digital Dividend 2 (700 band) • Countries using legacy systems in DD1 can start with DD2 and later add DD1
