TASKS FOR ANTEN AS 1.DEPLOYMENT PROJECT 2.TRIAL

DEPLOYMENT PROJECT FREQUENCY PLANNING BY RTUK BASIC INFORMATIONS ▫Mode: DVB-T2 ▫Reception Target : Indoor reception ▫Coding : 64QAM ▫FEC : 2/3 ▫Guard Interval : 19/256 ▫FFT Size : 32K ▫Pilot Pattern: PP4 ▫Channel Bandwidth : 27 Mbps

DEPLOYMENT PROJECT FREQUENCY/NETWORK PLANNING BY RTUK BASIC INFORMATIONS - 9 Mux (8 UHF, 1 VHF) planned - 7 Mux (UHF), Nationwide, tendered - 1 Mux, TRT - 5 Mux, National Private - 1 Mux, Regionals,Locals sites planned !- LAW NATIONAL BROADCASTER - 70% Population (Whole Country) REGIONAL BROADCASTER - 70% Population (Whole Region) MIN NETWORK (National) 379 SITE > 70 % POPULATION

DEPLOYMENT PROJECT 7 Mux / 379 Sites DTT NETWORK PLANNING Head – End National Broadcasters Reginal ( 4 / Region) * 7 Local Broadcasters ( 7/ City) * 81 Transmitter Sites - Site Coordinates ( Frequency Plan by RTUK) - EIRP (Max) ( Frequency Plan by RTUK) - Tower Heights (Max) ( Frequency Plan by RTUK) Tranmitter Powers, Antenna Sytems,Combining Systems,Energy Lines, Buildings, Site Communication/Management Systems,Redundancy……..

DEPLOYMENT PROJECT 7 Mux / 379 Sites DTT NETWORK PLANNING MANAGEMENT / OPERATION Optimized management model defined Employee, quantity, qualification defined CAPEX, Investment Costs OPEX, Operation Costs Site Serveys, in operation Existing Sites (Stations: Towers, antenna systems, buildings,energy…..) New Sites

TRIAL City: Ankara (Capital City) Population: 4.6m Area: 2.516km 2 Planned Site : 4 Planning Mode: SFN Area Definition: Urban No sea, no river Surrounded by mountains Higher buildings  concreat  glass covered buildings Rural Area (Far from downtown, in coverage) Close to co-channel interference Not so huge as Istanbul for traffic / easy to measure Enough SFN site (not few, not many) Existing stations Possibility to use R/L or fiber distribution instead of satellite

TRIAL Trial Project Prepared Site : 3 existing ( Planned : 4) Avaliable capacity in existing stations Simulations: Coverage & Interference Mux : 2 HD, 5 SD : 27 Mbps Distribution : Satellite Measurement : 2 set of measurement equipments - Vehicle : Outdoor measurement - Portable : Outdoor / Indoor measurement

TRIAL Outdoor Measurement / Vehicle Indoor Mesurement / Portable Set-Top-Box Monitor GPS TV ANALYSER 2m

TRIAL Outdoor Measurements : Coverage, Signal Field Strength Indoor Measurements : Indoor Reception Homogeneously Ankara Ground Floor → Top Different Points in a room Same axis / Opposite axises Report is in process

CONCLUSIONS TrialQuite Succesfull, some changes in power levels Gap Fillers Mobile < 50 kmph Evaluation / RTUK Antenna Set Top Box !
