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.

Eirene SRS 3.2.3 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 (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. 2701 m
– 160km/h speed, ETCS Level 1

– 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

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 Drive Test Result for Coverage Coverage requirement >-82dBm is met. Tunnel coverage also tested for subset 093 for data
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
