Croatia is currently developing the Strategy for the transition of digital terrestrial television to DVB-T2 standard and the assignment of the frequency spectrum at 700 MHz, i.e. the second digital dividend, for mobile services. The main goal of this Strategy is to make an additional part of RF spectrum (694-790 MHz) available for the mobile broadband services, but also to assure the competitiveness of the digital terrestrial television platform until 2030.

Impacts and Benefits of Transition to DVB­T2 and  Assignment of Second Digital Dividend Ana Katalinic Mucalo 1, Kresimir Mazor 1, Ivana Drazic Lutilsky 2  Croatian Regulatory Authority for Network Industries, Roberta Frangesa Mihanovica 9, Zagreb, Croatia  University of Zagreb, Faculty of Economics and Business, Trg J. F. Kennedy 6, Zagreb, Croatia ana.katalinic@hakom.hr Abstract  ­  Croatia  is  currently  developing  the  Strategy  for  the  transition of digital terrestrial television to DVB­T2 standard and  the assignment of the frequency spectrum at 700 MHz, i.e. the  second digital dividend, for mobile services. The main goal of this  Strategy is to make an additional part of RF spectrum (694­790  MHz) available for the mobile broadband services, but also to  assure   the   competitiveness   of   the   digital   terrestrial   television  platform until 2030. This extensive process includes several key  aspects, namely technical, economic and regulatory, which need  to   be   carefully   assessed   in   order   to   provide   economically   and  technically sound background for the development of the market  of   electronic   communications   While   technical   and   regulatory  aspects   are   more   straightforward   and   adequately   covered,   the  socio­economic  aspect is  a more  complex matter  as it  includes  also deeper impacts on the national economy and society. This  paper   addresses   the   economic   impact   and   benefits   of   the  transition   to   DVB­T2   standard   and   the   release   of   the   second  digital dividend. The costs of the transition to DVB­T2 have been  analyzed and presented. The spectrum pricing, methodology and  conditions for the assignment of the 700 MHz band have been  assessed and discussed this   spectrum   available   for   mobile   services   by   2020   This  process affects all layers of society, namely citizens, industry  and   state,   and   needs   to   be   planned   carefully   Croatia   is  currently   drafting   the   Strategy   for   the   transition   of   digital  terrestrial television to DVB­T2 standard and the assignment of  the   frequency   spectrum   at   700   MHz,   (hereafter:   Strategy),  which should be adopted by the end of 2016 Keywords  ­  spectrum pricing; second digital dividend; DVB­T2  transition; 700 MHz frequency band The   Strategy   includes   several   aspects   and   its  implementation   challenges   have   been   discussed   in   [2].  Technical   aspects   cover   all   relevant   issues   regarding   the  transition   of   DTT   to   DVB­T2   standard   (different   multiplex  scenarios, coordination issues, interference analysis, equipment  issues etc.) and the assignment of the second digital dividend  (e.g   parameters   and   procedure   for   managing   interference  between LTE and DVB­T2 devices), while regulatory aspects,  including appropriate revision of the national legislation, are  rather straightforward and in service of the strategic decisions.  The social and economic aspects, however, which are in focus  of this paper, are more delicate matter since they directly tackle  all stakeholders, including end users. They include all direct  and indirect benefits and impacts to the (state) economy and  society,   as   well   as   promotion   and   informative   campaigns,  which in fact should justify the whole process and answer the  simple question: why we are doing this?  I  INTRODUCTION Allocation of 700 MHz frequency  band (694­790 MHz),  i.e   second   digital   dividend   for   IMT   (International   Mobile  Telecommunications)  is a hot topic in the field of spectrum  management   The   background   is   obvious:   the   expansion   of  mobile services all over the world, increased number of users  and   the   constant   need   for   more   capacity,   have   led   to   the  growing   demands   of   mobile   industry   for   additional   RF  spectrum   Thanks   to   its   very   convenient   propagation  characteristics,   which   provide   better   coverage   and   service  accessibility, 700 MHz band, along with 800 MHz (790­862  MHz) band, has become one of the most attractive parts of RF  spectrum.  The Strategy has two main goals: (1) to make 700 MHz  spectrum   available   for   mobile   broadband,   in   line   with  European   decisions   and   strategy;   and   (2)   to   preserve   the  competitiveness of the DTT until 2030. By allocating 700 MHz  for   mobile   services   this   spectrum   will   be   harmonized   on  international   level,   which   besides   all   other   benefits,   opens  additional   opportunities   for   the   development   and  implementation of new services and technologies. On the other  hand,   the  question  of   preserving   DTT   has   broad   social   and  cultural effects, especially in countries where this platform is  dominant for TV signal transmission, such as Croatia. All DTT  services have to be accommodated adequately in a smaller part  of   spectrum,   which   is   financially   and   organizationally  challenging process.  The 700 MHz band is currently used for digital terrestrial  television (DTT), which needs to be migrated in order to make    This   date   is   defined   by   the   DECISION   OF   THE   EUROPEAN  PARLIAMENT AND OF THE COUNCIL on the use of the 470­790 MHz  frequency band in the Union [1] II SOCIO­ECONOMIC ASPECTS As mentioned in the introduction, the migration of DTT,  which   is   a   fully   built   and   operational   network,   in   order   to  release   the  700  MHz  spectrum  and  make  it  available   for  a  different kind of services, has an impact on everyone. While  this can be technically and economically justified, its social  impact, especially consequences for every end user, need to be  addressed   as  well  and   included  in  the  national   Strategy  In  general,   economic   aspects   include   all   market   analysis,  transition costs and financial framework of the Strategy, while  social aspects include all activities related to the information  and public awareness campaign and customers education. In  both   cases   immediate   and   long­term   impacts   need   to   be  analyzed Immediate socio­economic aspects which are prerequisites  for building the Strategy include: ­ ­ ­ ­ analyses of the costs of the transition from DVB­T to  DVB­T2 standard; analysis of the spectrum prices that could be achieved  for the second digital dividend; delivery   of   public   awareness   and   information  campaign; financial   framework   for   the   implementation   of   the  Strategy   (includes   all   direct   costs   for   the   above  mentioned activities, necessary for the implementation  of the Strategy).  ­ social   effect   of   bypassing  the   digital   divide   between  well­developed urban and underdeveloped rural areas; increased GDP and economic growth motivated by the  availability of high speed broadband ­ Clearly, some of the aspects listed are straightforward and  can   be   easily   quantified,   while   the   others   are   just   expected  (positive) outcomes that cannot be guaranteed. However, they  should   be   supported   by   specific   activities   and   incentive  measures included in the Strategy, as will be discussed in the  following sections III COSTS OF THE DVB­T2 TRANSITION AND SPECTRUM  PRICING FOR THE SECOND DIGITAL DIVIDEND A  Transition of DTT to DVB­T2 Standard Almost 50% of households in Croatia use DTT platform  exclusively. Fig. 1 shows the current state of market of digital  television Deeper and long­term effects of the transition to DVB­T2  and the assignment of the second digital dividend for mobile  services should justify the whole process: ­ ­ ­ ­ ­ ­ ­ ­ better TV quality and new services available to more  than 95% of population; competitive DTT market compared to other platforms  (IPTV, cable TV etc.);  better, faster and cheaper communications available to  all citizens; availability of a larger number of multimedia content  that directly affects the effectiveness of business and  educational processes on all levels, which can reflect  on   the   general   increase   in   population   education   and  economic growth; better productivity due to the access to broadband and  application of new ICT services, as well as decrease of  operational costs; opportunity for new economic subjects and increased  number of new jobs; better   life   quality   due   to   the   service   and   content  availability, especially in rural and remote areas, which  has positive effects on equal regional development in  the Republic of Croatia; infrastructure  investments which motivate the market  in   the   first   place,   but   also   the   entire   information  society; Figure 1. DTT market overview with different technologies [3] Other platforms have significantly lower share (IPTV has a  share of 25.88%, cable TV 10.35%, and satellite TV 11.17%),  although there is a tendency of increasing those shares since  more and more operators offer packages of internet and TV  services   Currently   deployed   DTT   platform   for   free­to­air  (FTA) programs is based on DVB­T standard and MPEG­2.  Part of the DTT platform is used for Pay TV, which has the  market share of 4.11%. The only Pay TV operator, EVO TV,  uses DVB­T2 standard with MPEG­4 [3].  DTT   FTA   programs   are   available   to   more   than   96%   of  population (MUX A and MUX B) free of charge, which is why  it is in the national interest to preserve it. However, in order to  set   appropriate   conditions   for   the   development   and  sustainability of the DTT market until 2030, it is necessary to  reconcile   current   and   future   demands   for   the   additional   TV  content   and   new   services   or   better   quality   of   the   existing  services. More thorough analysis can be found in [2]. Based on  the discussions and conducted analyses related to Strategy [2,  4], the transition to the most advanced platform, i.e. DVB­T2  standard   with   H.265/HEVC   coding   is   the   most   promising  scenario for the transition of DTT in Croatia. DVB­T2 standard  provides higher data rates and better robustness, thus enabling  significant   capacity   improvements   compared   to   DVB­T  standard and better availability, while H.265/HEVC introduces  additional   benefits   to  the   capacity   This  combination   allows  better quality (HD TV) with the same bitrate (and the same  costs) and it also enables further development and introduction  of both technology and services in DTT.   The   transition   to   DVB­T2   includes   significant   costs   at  different levels that need to be taken into account and assessed.  Besides   only   listing   and   calculating   the   expenses,   it   is   also  important  to analyze  and apply all  the possibilities for  their  reduction   The   most   considerable   part   of   costs   lies   on   the  network   operator   which   needs   to   make   technological  adjustments. This includes  costs of the network re­planning,  equipment   replacement,   adjustment   to   the   HD   transmission,  transition period (simulcast) and cost of the information and  public awareness campaign. End users will have to invest in  new receivers.  The mitigating factor for the network operator is the fact  that the transition is targeted around year 2020, which ties in  with the  natural  depreciation   of  equipment   of  10 years   (the  equipment has been implemented during the transition in 2009  and 2010). As for end users, during the first digitalization the  state   provided   subventions   by   issuing   vouchers   for   citizens  who were paying TV fee that partially covered the cost of a  receiver   The   same   principle   is   expected   for   this   transition.  However, this cost can be significantly reduced by adequate  preparation   of   the   market   for   the   upcoming   changes   This  includes   timely   delivery   of   the   specification   on   minimal  technical   requirements   for   the   equipment   and   appropriate  promotion and information campaign as soon as possible. This  would give the market approximately 3 years to adapt to the  future   changes   by   reducing   the   number   of   non­compliant  receivers Conducted   and  planned   analyses  rely  on  lessons  learned  and   costs   from   the   first   digitalization,   i.e   activities   and  implementation of the Strategy of transition from analogue to  digital terrestrial television [5, 6]. The exact data are available  on­line to a limited extent within the published annual and final  reports2).  B Spectrum Pricing of the Second Digital Dividend One of the direct benefits of the release and allocation of  700 MHz frequency band to mobile services is the expected  price of the spectrum that can be achieved. Due to its scarcity,  but very favorable propagation characteristics, there is a huge  interest in 700 MHz band. Some countries (e.g. UK [7]) did an  extensive   research   which   clearly   showed   benefits,   where  projections   of   expected   gain   from   second   digital   dividend  exceeded the anticipated cost of the DTT transition   e­Croatia   2004­2011,   available   at  https://uprava.gov.hr/o­ ministarstvu/ustrojstvo/uprava­za­e­hrvatsku/arhiva­projekata/e­ hrvatska­2004­2011/916, June 2016; Transmitters   and   Communications   Ltd.,   Annual   reports,   available   at:  http://www.oiv.hr/tvrtka/izvjesca/izvjesca­god/izvjesca­god_hr.aspx High   expectations   for   the   second   digital   dividend   are  usually compared with the results achieved for the first digital  dividend,   i.e   800   MHz   frequency   band,   but   this   has   been  argued by many. An overview of the spectrum pricing for the  first digital dividend (frequency band 800 MHz) in Europe has  been given in [8]. However, several parameters should be taken  into account  before setting conditions for 700 MHz auction.  For example: ­ ­ ­ ­ interest   and   suitable   timing   of   mobile   operators   to  invest  in 700 MHz – both depend on the number  of  users   and   necessary   capacity   Bigger   interest   can   be  expected from operators which do not have 800 MHz,  but this assumption cannot be taken for granted as RF  spectrum   is   a   scarce   natural   resource   and   obtaining  additional RF spectrum can be a strategic decision; interest   of   operators   for   other   frequency   bands   for  mobile service (900 MHz, 1800 MHz, 2100 MHz, 2600  MHz) – although 700 MHz and 800 MHz are attractive  due to their ability to provide wide coverage with less  base stations, higher frequency bands are quite suitable  for building up the additional capacity. Considering that  the highest capacity demands are in urban areas where  smaller cells are required, the interest for those bands  (above 1800 MHz) could surpass the one for 700 MHz,  especially   having   in   mind   that   most   operators   have  already established the adequate coverage; decision on having the auction for 700 MHz only or  joint mega­auction for several frequency bands – both  approaches have been applied for 800 MHz across the  Europe and the decision will depend on the previous  two   conditions   Current   licenses   in   Croatia   expire   in  2024. At the moment, the operators are not interested in  mega­auction,   due   to   necessary   investments,   but   it  could   be   reconsidered   depending   on   the   conditions  offered; additional requirements for coverage obligations – 700  MHz   is   suitable   for   covering   “non­commercial”  locations,   which   should   be   promoted   by   the   state.  However, imposing this condition affects the final price.  The same applies for imposing minimum requirements  for the quality of service (QoS); Apart from that, before assigning the spectrum the interest  for other services (SDL, PPDR, M2M, PMSE) should also be  taken into account  There  are  also other parameters  that are  specific   to   a   certain   country,   which   should   be   considered.  Some   theoretical   approaches   have   been   systematized   and  described   in   [9]   Croatia   for   example   has   a   distinctive  geographical diversity, including a large number of inhabited  islands,  which   has  a  deep   impact   on  the  population  density  distribution,   leading   to   a   large   number   of   rural   and   remote  (non­commercial)   areas   It   is   therefore   crucial   to   encourage  investments   in   those   areas   in   order   to   decrease   the   digital  divide   between   different   regions,   which   can   be   successfully  achieved by LTE technology in 700 MHz frequency bands TABLE I. COMPARISON OF 700 MHZ AND 800 MHZ 60 MHz @ 700 MHz 60 MHz @ 800 Germany Total EUR/capita3 Total EUR/capita France band 1.000.445.000,00 12,37 2.798.976.324,00 44,56 ­ MHz 3.576.475.000,00 44,23 2.639.087.005,00 42,01 At the moment, only France and Germany have assigned  700 MHz band [10, 11]. France has sold 700 MHz spectrum  for the total price of 2.8 billion euros, which is near the value  achieved for the 800 MHz band. Germany on the other hand  assigned this spectrum in the joint mega­auction for 700 MHz  band, the GSM bands (900 MHz and 1800 MHz) and the L­ band (1452–1492 MHz). The achieved price of total 5.1 billion  euros was quite a success, but the expected prices for 700 MHz  have not met the expectations and the band attracted “only” 1  billion   euros,   i.e   less   than   the   value   of   the   first   digital  dividend. A brief comparison for French and German auction  for 700 MHz and 800 MHz are given in the Table I.  It is hard to draw any conclusions based only on the cases  of France and Germany, but there are some lessons that might  be learned. For example, the joint auction in Germany showed  a   great   interest   for   1800   MHz   band,   which   has   smaller  coverage than 700 MHz, but it is more convenient for high­ density urban area, where most users are settled. This could be  explained by the fact  that the existing operators had already  established the coverage, which is the main advantage of lower  frequency   bands,   and   the   additional   spectrum   is   for   the  capacity increase only IV THE STRATEGY AND INCENTIVE MEASURES It   is   evident   that   both   transition   of   DTT   to   DVB­T2  standard   and   the   assignment   of   700   MHz   band   to   mobile  services   will   bring   many   benefits   In   order   to   create   an  environment   where   all   advantages   could   be   exploited,   it   is  important for the state and all other stakeholders to take their  roles   in   the   implementation   of   the   Strategy   The   incentive  measures planned in order to support the implementation of the  Strategy include: ­ ­ ­ starting   the   promotion   and   information   campaign   as  soon as possible. This will give all market stakeholders  enough time to prepare for the transition;
