  1. Digital Dividend and Plan Geneva 06 Communications Regulatory Authority of the Republic of LithuaniaDirector of Radiocommunications department dr. Mindaugas ŽilinskasWarsaw,7-9 May2012

  2. Plan Geneva 06 and Digital Dividend 1. Current situation of DTT in Lithuania. 2. Digital Dividend and related problems. Impact of DD1 on DVB-T networks. TV vs ARNS compatibility problems. c) Impact of ARNS on LTE. 3. Decisions of WRC-12 and a possible impact on DTT. Coordination problems of new stations or allotments. 4. Conclusions

  3. Current situation. 4 DVB-T networks: LRTC network 1 (2011-11-16) Start in 2002 regular:2004 MPEG-2 2006 06 01 MPEG-4 DVB-T, 64-QAM CR=3/4 LP=90% Coverage: territory: 86,9% population: 95% 32 stations

  4. LRTC network 2(2011-11-16) 27 stations 64-QAM CR=3/4 LP=90% Coverage: territory: 86,6% population: 95%

  5. TEO LTnetwork 1(2011-11-16) Network deployed by the company Toptronas 24 stations 64-QAM CR=3/4 LP=90% Coverage: territory: 82,1% population: 92%

  6. TEO LTnetwork 2(2011-11-16) 6 stations 64-QAM CR=3/4 LP=90% Coverage: territory: 58,8% population: 75% Calculation method

  7. Channel 57 Channel 60 Distribution of DVB-T stream in channels • 64 QAM, CR=3/4, GI=1/4 • Commonstream22,4 Mbps • 85% stream – TV progr. • 10 progr. 2 Mbps/progr.

  8. Measurements A view inside the car

  9. LTV programme, fixed reception receivers Kaon S660HD, Salteka settlements-no less than 500 inhabitants.

  10. Reception of LTV programme It was measured in 475 settlements (which comprise no less than 500 inhabitants), in 456 cases reception was good; In 19 cases there was no reception; These measurements covered population of 2,64 m , so 99,3% of them can receive the programmes transmitted over national LRTC network 1.

  11. Comparison of measured and calculated field strength values Method of calculations CCIR –Predict.

  12. Before WRC-12: four DVB-T networks in operation, beauty contest for two UHF networks and five analogue networks until 29 October 2012 LRTC 1 TEO 1 NAT5 NAT6 LRT LRTC 2 TEO2

  13. Digital dividend 1 (DD1) 61-69 TV channels (790-862 MHz) -Decision (2010/267/EU ) of theEuropean Commission on harmonized technical conditions on use in the 790–862 MHz frequency band for terrestrial system capable of providing electronic communication service in Europe. -RadiospectrumpolicyprogrammeapprovedbytheEuropeanParliament on 16 February 2012. From 1 January 2013 – the800 MHz band, article 6 paragraph 3.

  14. Channel arrangement for ECN in the 790-862 MHz frequency band

  15. Digital dividend I (TV channels 61-69) 64 61 63 65 65 26 61 62 65 64 63

  17. Coordination in the 791-821 MHz & 832-862 MHz bands: - Between base stations of MS (LTE vs. LTE) • Stations of MS and ARNS (LTE vs. ARNS) • Agreement came into force on 1 January 2013.

  18. ARNS at the western border of Lithuania (registered in MIFR)

  19. ARNS operating under umbrella of DVB-T stations in TV channels 67 and 69 at the western border of Lithuania

  20. Impact of LTE network (model) BS onstations of ARNS. Cells R=8 km, P=55 dBm

  21. Method of calculations The field strength is calculated by power sum method: Esum — cumulative field strength; Ei — the field strength produced by i-base stations; n — number of base stations. ITU – R. P Recommendations 1546, 525.

  22. The dependence of cumulative field strength value of LTE network from the number of BS The frequency of all BS:ν = 826 MHz

  23. Real network of MS (GSM) in the area of Kaliningrad district

  24. Impact of the“real network” LTE BS on ARNS , network up to 30 km. R = 30 km

  25. Impact of the“real network” LTE BS onARNS , network up to 50 km. R = 50 km

  26. Impact of the“real network” LTE BS on ARNS , network up to 70 km. R = 70 km

  27. The field strength of a theoretical model of LTE network and a real one with a different radius

  28. Impact of terminal equipment onreceivers of ARNS on aircrafts

  29. Impact of terminal equipment ona receiver of ARNS on aircraft. Initial conditions:

  30. Impact of terminal equipment on a receiver of ARNS on aircraft. E ≤ 72 dBμV/m

  31. Coordination criteria: on the border line and at the location of ARNS • Restrictions of electromagnetic field strength on the border line depending on geographical longitude (antenna high 10m): • till 21º 07′ (53dBµV/m@5MHz) • from21º 07′ till 22º 34′ (57dBµV/m@5MHz or 58dBµV/m@5MHz) • from22º 34′ (58dBµV/m@5MHz) • Buffer zones: • e.i.r.p • 55dBm/5MHz (till 60km); 55dBm/5MHz or 58dBm/5MHz (60-100km distance) • Effective antenna high (heff) • heff= 60m (iki 60km) • BS density • 1BS/100km2; 10BS/100km2; 100BS/100km2or 50BS/100km2

  32. Results : Restrictions on the LTE

  33. Impact of ARNS on LTE RECOMMENDATION ITU-R M.1830 (1)

  34. ECC Report 174. COMPATIBILITY BETWEEN THE MOBILE SERVICE IN THE BAND 2500-2690 MHz AND THE RADIODETERMINATION SERVICE IN THE BAND 2700-2900 MHz

  35. 6.2 Impact of radar on the LTE base station (ECC Report 174) Required additional isolation needed for interference from radar type 2 to LTE BS

  36. …VoIP is very sensitive to packet loss, delay …100 ms, delays greater than 200 ms are noticeable to the end users. …it is impossible for LTE to provide a wide range of services with an acceptable QoS

  37. Possible impact of ARNS RLS type 2 on LTE BSITU-R.P. 1546-3, T=10%, L=50%. Gr=18 dB, h=60m, C/I=-6dB, Ps1=-98 dBm; Ps2=-115 dBm, (E1=21 dBuV/m, E2=4 dBuV/m) for radar mean power: Ptr=19.5 dBW,

  38. Possible impact of ARNS RLS type 2 on LTE BSITU-R.P. 1546-3, T=10%, L=50%, Gr=18 dB, h=60m, C1/I=-6dB,C2 /I =0, Ps=-98 dBm; (E1=21 dBuV/m, E2=27 dBuV/m) for radar pulse power Ptr=52.5 dBW,

  39. How many Digital dividends should we take into account? • Digital dividend 1 (DD1) 61-69 channels (790-862 MHz) • Digital dividend 2(DD2) 49-60channels (694-790 MHz) . Digital dividend 3 (DD3)?

  40. WRC-2012 results

  41. Impact of digital dividends • After DD1, 8 networks left from 9 given according to Geneva 06 Plan: • 4 in use • 2 beauty tenders announced at the end of 2011 • 1 network is assigned for national radio and television (LRT) • 1network in VHF frequency band (to be licensed) • After DD2, 5½ networks: • <2 in use • 1.5for tender • Panevėžys, Biržai, Utena, Alytus and Kaunasallotments left • LRT full network • VHF full network.

  42. The consequencies of the DD2 for 2 new networks NAT 5

  43. The consequencies of the DD2 for LRTC network 1

  44. The consequencies of the DD2 for LRTC network 2 LRTC 2

  45. The consequencies of the DD2 for TEO LT network 1 TEO 1
