Central and Eastern European Countries Regional Working Group Bucharest, 26 – 27 May 2014 Opportunities and challenges of utilization of digital dividend in 700 MHz Nikolai Vassiliev International Telecommunication Union RadiocommunicationBureau
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 2
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) 3
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 . 29 km 157 km 107 km 4
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) ТВ IMT ЗП 48 ТВК F, МГц 694 МГц 5
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 . 6
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 . 7
Results of re-planning for African countries Percentage of assigned (satisfied) channels - 97.32 % 470-694 MHz 694-862 MHz Layer 1 DD1 Layer2 DD2 Layer 3 Layer 4 Mobile? 8
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 9
Situation in CEE countries in GE06 Plan Distribution of TV channels in 470 – 694 MHz in GE06 Plan (on 23.0514) From Difficult To Easy 10
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 11
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 12
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 14
