Opportunities and challenges of utilization of digital dividend in 700 mhz

Central and Eastern European Countries Regional Working Group

Bucharest, 26 – 27 May 2014

Opportunities and challenges of utilization of digital dividend in 700 MHz

Trends in utilization of uhf band

Trends in utilization of UHF band

  • Transition to Digital Television (DTT)

    • Better quality, new services, compression of programs:

      • 1 TV channel = 1 analogueprogram

      • 1 TV channel = 2 - 16digitalprograms (DVB-T2/MPEG4)

    • Transition to Digital Television (DTT - >released spectrum

Digital Dividend(DD). It can be used by:

  • Television: more programs, HDTV, 3D, mobile TV ...

  • Mobile broadband ->growing traffic, rural areas

  • Other applications, e.g. PPDR

  • Each country decides how to use DD

  • DD1: 790-862 MHz (WRC-07). EC Decision 2010/267/ the 800 MHz band -> for Mobile Broadband

International regulations of 700 mhz dd2

International regulations of 700 MHz (DD2)

Probably after WRC-15

After WRC-12

  • 694–790 MHz – allocated to mobile and broadcasting co-primary from 2015

  • Choice of the service – national decision, but regional harmonization is extremely important

3.5 year studies

Join Task Group JTG 4-5-6-7

Band 694 – 790 MHzallocated to mobile service, entry into force postponed until WRC-15 (Res. 232)

Importance of harmonized allocation of dd2

Importance of harmonized allocation of DD2

  • Difficulties of sharing mobile service and TV (required separations up to 140 – 160 km (studies 800 MHz)

  • Advantages of using Digital Dividend 2 for mobile service:

    • Satisfy growing traffic requirements in mobile broadband

    • Enable larger coverage areas (benefits for rural areas)

    • Harmonization also leads to:

      • Reduced prices of mobile terminals in mass production

      • Reduced complexity of radio design

      • International roaming

      • facilitated border coordination

Itu r studies of 700 mhz jtg4 5 6 7

ITU-R studies of 700 MHz (JTG4-5-6-7)

  • Continuing studies of out-of-band interference from IMTto TV

  • Lower boundary of 700 MHz band is determined as 694MHz

.

  • Defining guard band between IMTand TV (otherwise filters on TV, higher requirements to mobile devices - costly)

  • Determination of sharing conditions between IMT and aeronautical navigation

  • Development of harmonized frequency plans for mobile service (for plans starting from 703 MHz guard band of 9 MHz may be sufficient)

Digital dividend and agreement ge06

Digital Dividend and Agreement GE06

  • Band 470 – 862 MHz is regulated by Agreement GE06. Any change in frequency shall be coordinated via GE06 procedure

  • If DD2 is used for mobile, TV should be moved to the bands below 694 MHz. GE06 Plan shall be updated

  • Challenge: to satisfy significant number of TV requirements in below 694 MHz to open the bands above 694 MHz for mobile

  • Possible solution:

    • Coordinate TV requirements in 470 -694 MHz at sub-regional level

    • Submit the coordinated requirements to ITU to update GE06 Plan

  • ITU is ready to provide assistance during all steps of this process

Allocation of dd in other regions sub sahara africa

Allocation of DD in other regions: Sub-Sahara Africa

  • Decided to allocate the first and second digital dividend to the mobile service above 694 MHz

  • ATU Ministerial Summits in December 2011 (Nairobi), September 2012 (Accra) and May 2014 (Nairobi)

  • Recommended the adoption of DVB-T2 and MPEG4

  • Decided to re-arrange GE06 Plan on the basis of 4 national layers (multiplexes) per country. Negotiations started in March 2012 and were completed in July 2013 with 33 iterations

  • Used relaxed coordination criteria: 4 dB instead 1.25 for GE06

  • Recommended the end of analog switch-off by 17 June 2015

Opportunities and challenges of utilization of digital dividend in 700 mhz

DD in other regions: Arab countries, Black/Caspian Seas

  • Arab countries

    • First Arab frequency coordination meeting, Dubai, 17-23May 2014 Participation of 28 countries. Objective: coordination DTT channels in 470–694 MHz

    • Agreed on principles: 4 layers, coordination margin = 4 dB, generating requirements for non-participating countries

    • Start of re-planning – September 2014, finish – February 2015

  • Black/ Caspian sea Sub-Region

    • ARM, AZE, GEO, IRN, KAZ, KGZ, RUS, TJK, TUR, TKM, UKR and UZB

    • 1stsub-regional frequency coordination meeting of Administrations of Black and Caspian Seas in 18-19 Apr 2013

    • 2nd meeting in autumn 2014. One of items to discuss: to access possibility to satisfy broadcasting requirements in 470 – 694 MHz

How ITU can assist administrations ?

  • Generation of the initial requirements (to reach a required number of layers). Software tool - GE06 Calc

  • Adaptation of the necessary software for your Sub-Region

  • Assistance in compatibility analysis (regional iterations )

  • Assistance in the frequency coordination meetings among your administrations and countries in neighboring regions

  • Taking care of finding available channels for the ‘absent’ administrations’ (4 layers), if any

  • Assistance all along the process

Conclusions

  • Allocation of Digital Dividend 2 is national decision

  • However, regional/word harmonization is extremely important

  • A number of Region 1 countries already decided to allocate DD2 for mobile broadband, while using 470 – 694 MHz for DTT

  • Moving DTT from the 700/800 MHz to lower bands is possible through sub-regional frequency coordination meetings

  • Re-planning in Africa demonstrated that the objective of a minimum of 4 coverage layers can be achieved

  • ITU is ready to provide assistance in these activities to any regional sub-group

Opportunities and challenges of utilization of digital dividend in 700 mhz

Challenges in liberating Digital Dividend 2

  • To coordinate with TV stations of countries of other sub-regions

  • To coordinate with aeronautical radionavigation of countries in RR 5.312

  • To take into account applications ancillary to broadcasting, e.g radio microphones (see RR 5.296)

  • After completion of regional coordination, to continue with bilateral coordination to address difficult areas
