GSM-R Projects: Projects Map *Taken from 11th transportation, maritime and communication council report, june 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.

GSM-R Projects (Completed): Ankara-Eskişehir-İnönü-NSS Part Line Characteristics: –276 km, Double Track –Speed: 250km/h, ETCS Level 2 (ETCS Level 1 as fallback) GSM-R Project Data (NSS Part) –Vendor: NSN –NSS system components: MSC/VLR, HLR/AuC, (R99 version), GPRS, IN, SMS-C, Dispatcher PBX, AcK, Dispatcher Consoles, VRS, OMC-S –For ETCS Level 2, 3 RBC connected to MSC

GSM-R Projects (Completed): Ankara-Eskişehir -İnönüPhase I - BSS Part GSM-R Project Data (BSS Part) –Double Layer Radio Coverage (Co-Sited) -85dBm, -75dBm, -92dBm and -77dBm target coverage levels for trains, stations/shunting yards, handheld portables and tunnels, respectively. –#BTS sites:37 for each for each radio layer (total=74) –2 BSC and TRAU for double layer coverage –OMC-R for BSS management

GSM-R Projects: BSS Architecture For Co-sited Double Coverage MSC

Line Characteristics: –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 compliant: -92dBm, -94dBm, -99dBm, -82dBm target coverage level for trains, shunting,handheld portables and tunnels, respectively. –Integrated into existing NSS –OMC-R for BSS –1 BSC and 1 TRAU, 21 BTS –2 RBC connected to MSC GSM-R Projects (Completed): Ankara-Konya

GSM-R Projects (On-Going): Ankara İstanbul Phase II İnönü- Köseköy Section Line Characteristics: – Approximately 150 km, several tunnels of total length approx. 60 km – Speed: 250km/h speed, ETCS Level 2 (Level 1 as fallback) GSM-R Project Data – Vendor: NSN – Double Layer Radio Coverage (Co-sited for open area, interleaved in tunnels): -92dBm, -94dBm, -99dBm, - 82dBm target coverage levels for trains, shunting and handheld portables and tunnels respectively – BTSs are connected to existing BSCs (Phase I), BSS Integrated into existing NSS – # BTS sites: 44 (22 each layer), Each Layer connected to different BSCs, – Tunnel Coverage: F/O Repeaters, Leaky Feeder, Mu’s and OMC for Repater system – 2 RBC will be connected to MSC

GSM-R Projects (On-Going): KÖSEKÖY-GEBZE-İstanbul (Haydarpaşa) Section Line Characteristics: – Approx. 100 km(coverage requirement for GSM-R ), 10 tunnels of total length approx m – 160km/h speed, ETCS Level 1 GSM-R Project Data – Vendor: Kapsch – Double Layer Radio Coverage (Interleaved using 1 BSC): -85dBm, -82dBm, -99dBm target coverage level for trains, station/shunting yards and handheld portables, respectively In case of one BTS failure, -92dBm coverage requirement – Will be integrated into existing NSS – 1 BSC

GSM-R Projects: Köseköy-Gebze BSS Architecture Against failure of one BTS site following scheme is adopted. -92dBm

TUNNEL COVERAGE APPLICATIONS-I To raise the reliability of tunnel coverage system, the donor signals of two-adjacent BTS sites signal is fed to each repeater. Additionally, inside the tunnels each RU is placed to ensure coverage even if one RU fails (interleaved coverage)

TUNNEL COVERAGE APPLICATIONS-II Tunnel coverage scheme using antennas: 1 tunnel approx. 2km length Coverage requirement >-82dBm is met. Tunnel coverage also tested for subset 093 for data Drive Test Result for Coverage

GSM-R QoS Drive Tests Applications For Voice Quality; –Coverage level, RxQual –Handover success rate, Handover execution delay –Connection establishment delay (also for ETCS data) –Cell (re)selection/HO ping pong –Call Set up success rate, Connection Drop Rate (also for ETCS data) –In Tunnel Coverage –Handheld Units Coverage For Data (in accordance with Subset 093); –Data transmission interference rate –Transfer delay of user data frame –Connection loss rate (data) –Network registration delay
