  3. GSM-R Projects: Projects Map • *Taken from 11th transportation, maritime and communication council report, june 2013. • Already, about 480 km of HS tracks deployed/contracted for GSM-R system. • Also, GSM-R has beginned to be installed on Conventional Rail lines to replace old analog radio systems.

  4. GSM-R Projects (Completed):Ankara-Eskişehir-İnönü-NSS Part LineCharacteristics: • 276 km, Double Track • Speed: 250km/h, ETCS Level 2 (ETCS Level 1 as fallback) GSM-R Project Data (NSS Part) • Vendor: NSN • NSS systemcomponents: • MSC/VLR, HLR/AuC, (R99 version), GPRS, IN, SMS-C, Dispatcher PBX, AcK, DispatcherConsoles, VRS, OMC-S • For ETCS Level 2, 3 RBC connectedto MSC

  8. GSM-R Projects (Completed):Ankara-Konya LineCharacteristics: • Approximately 212km, double track, 1 Tunnel of approx. 2km length • Speed: 250km/h, ETCS Level 2 (Level 1 as fallback) GSM-R Project Data • Vendor: Kapsch • Single Layer Radio Coverage • Eirene SRS 3.2.3 compliant: -92dBm, -94dBm, -99dBm, -82dBm target coverage level for trains, shunting,handheld portablesand tunnels, respectively. • Integratedintoexisting NSS • OMC-R for BSS • 1 BSC and 1 TRAU, 21 BTS • 2 RBC connectedto MSC

  9. GSM-R Projects (On-Going):Ankara İstanbul Phase II İnönü-Köseköy Section LineCharacteristics: • Approximately 150 km, severaltunnels of total lengthapprox. 60 km • Speed: 250km/h speed, ETCS Level 2 (Level 1 as fallback) GSM-R Project Data • Vendor: NSN • DoubleLayerRadioCoverage (Co-sitedforopenarea, interleaved in tunnels): • -92dBm, -94dBm, -99dBm, - 82dBm targetcoveragelevelsfortrains, shuntingandhandheldportablesandtunnelsrespectively • BTSsareconnectedtoexistingBSCs (Phase I), BSS Integratedintoexisting NSS • # BTS sites: 44 (22 each layer), Each Layer connected to different BSCs, • TunnelCoverage: F/O Repeaters, LeakyFeeder, Mu’sand OMC forRepatersystem • 2 RBC will be connectedto MSC

  10. GSM-R Projects (On-Going):KÖSEKÖY-GEBZE-İstanbul (Haydarpaşa) Section LineCharacteristics: • Approx. 100 km(coveragerequirementfor GSM-R ), 10 tunnels of total lengthapprox. 2701 m • 160km/h speed, ETCS Level 1 GSM-R Project Data • Vendor: Kapsch • DoubleLayerRadioCoverage (Interleavedusing 1 BSC): • -85dBm, -82dBm, -99dBm targetcoveragelevelfortrains, station/shuntingyardsandhandheldportables, respectively • Incase of one BTS failure, -92dBm coveragerequirement • Will be integratedintoexisting NSS • 1 BSC
