  2. Rationale for keeping the sub 700 MHz 1. WRC-15 affirmed the global allocation to broadcasting in the UHF band. 2. DTT is a vital, unifying, and universal service providing public information and entertainment. It is necessary, successful, economically-attractive and evolving. It is being implemented across the world. 3. IMT has sufficient spectrum, much of which is underutilized or unused. 4. IMT identification in some countries increases cross- border coordination difficulties. 5. PMSE and other unlicensed services can co-exist with DTT but cannot co-exist with IMT.

  3. WRC 15 has secured allocation to Broadcasting

  4. DTT is a Vital, Unifying and Universal Service 1. Informs, educates and entertains 2. Links citizens together across a country in context with the global community. 3. Free to all 4. The most efficient and cost-effective means to communicate with a country’s entire population, especially in remote areas.

  5. DTT is a Necessary Service 1. A vital part of the communication and information infrastructure of all civil societies 2. Provides critical survival information in emergency situations

  10. DTT is Successful (USA) Broadcast Television Stations and OTA Viewership in USA 1800 18 Number of Over-the-Air Households (millions) 1600 16 Number of Full-Power TV Stations 1400 14 USA Analog Switch-off 1200 12 1000 10 (June 2009) 800 8 600 6 400 4 200 2 0 0 Year No. Stations No. OTA Households Sources: US FCC, Nielsen

  11. DTT is Successful (Europe)

  12. DTT is economically attractive Cost savings due to digital multiplexing capabilities and power reduction (-7 to - 10 dB), compared to Analogue TV Analogue terrestrial television Digital terrestrial television MUX Program 1 Program 1 Program 2 Program 2 Program 3 Program 3 3 networks, high cost Additional program Additional program Shared network, shared costs Cost efficient coverage due to high tower topology, compared to low tower / cellular networks

  13. DTT is Evolving 1. Better quality: HDTV and UHDTV enabled by new coding and compression techniques, DVB-T2, MPEG4, HEVC. 2. Advanced Features: HDR, HFR, Wider Colour Space, NGA 3. Interactivity: HbbTV 4. Reception on mobile devices (smartphones, tablets) using Wi-Fi for distribution within the home (SatIP in Europe)

  16. IMT Already has Sufficient Spectrum (Some of Which is Unused) • The USA has 4 major wireless providers providing nationwide service.* • Each of the 4 nationwide providers has 110 ‒ 200 Mhz of spectrum below 3 GHz, some of which is unused • Additionally, speculators are holding spectrum, mostly unused, in the hopes of selling it to one of the nationwide carriers. One speculator holds over 90 MHz of unused spectrum below 3 GHz.* • "We don't have a spectrum shortage and never will," Marty Cooper, inventor of the cell phone.* * Sources: US FCC Wireless Competition Report (2015), Bloomberg Intelligence (2017), Marconi Symposium (2014).

  18. IMT-DTT Cross-border Interference Issues • Sharing between Broadcast Television and IMT requires 200+ km separation (ITU JTG 4-5-6-7) TV Station at Jayuya Puerto Rico (Green is predicted interference zone) Anguil An illa la BVI Domini inican can Republic ic USVI St St. Kit itts ts and Nevis is

  20. IMT/DTT Interference Areas in Portugal (solved) See Annex 4 of National field reports on the introduction of IMT in the bands with co- primary allocation to the broadcasting and the mobile services • http://www.itu.int/pub/R- REP-BT.2301

  21. IMT-PMSE and IMT-Unlicensed Co-existence Issues • Unlicensed TV White Space (TVWS) devices have shown promise for providing low-bandwidth internet access to remote locations • TVWS spectrum access requires that a database assigns frequencies opportunistically • TVWS frequency assignments are feasible for static transmitters, such as broadcast, but are infeasible in spectrum used for mobile IMT. • Similar conflicts will exist with PMSE/wireless microphone uses in IMT spectrum

  22. Conclusions 1. UHF spectrum is an essential resource for DTT and no changes should be made to existing allocations 2. No case for a global mobile allocation and IMT identification in the sub-700 MHz band
