  17. 17. Presentation on behalf of the TETRA + Critical Communications Association TETRA has flexibility in choice of frequency bands:  Other technologies, for example GSM-R, operate in the frequencies 876- 915/921-960 MHz or higher (as in Australia) requiring more base station repeaters than TETRA to obtain the same coverage. (Savings not only in radio equipment, but also in civil engineering, buildings/shelters, towers, etc…)  TETRA is four times more efficient using the spectrum than GSM-R. TETRA provides 4 channels in a bandwidth of 25 KHz, while GSM provides 8 channels in 200 KHz. (The use of the spectrum, which is a very limited resource today, is clearly optimized with TETRA) Basics of TETRA Technology (8) spectrum & spectral efficiency Telecommunications & Train Control Conference August 2014 350-370 Mhz, 380-400 Mhz, 410-430 Mhz 450-470 MHz bands and 800 Mhz.

Presentation on behalf of the TETRA + Critical Communications Association Railway Signaling using TETRA can provide a continuous data transmission (On-board Wayside Equipment) resulting in: High availability and Reliability Line train capacity optimization Reduced number of wayside equipment  Applicable to all safety and protection systems (ETCS, CBTC, PTC,..) TETRA and Railway Signalling for Safe and Efficient Operation (1) Telecommunications & Train Control Conference August 2014  Due to its flexible design, TETRA can be seamlessly integrated with other wide or broadband technologies for complementary solutions such as LTE
  20. 20. Presentation on behalf of the TETRA + Critical Communications Association TETRA and Railway Signalling for Safe and Efficient Operation (2)  ERTMS (European Rail Traffic Management System)  ETCS (European Train Control System)  RBTC (Radio Based Train Control)  CBTC (Communication Based Train Control)  PTC (Positive Train Control)  ITCS (Incremental Train Control System (Federal Rail Administration USA) Telecommunications & Train Control Conference August 2014
  21. 21. Presentation on behalf of the TETRA + Critical Communications Association  TETRA supports the ETCS requirements for the communication systems. The ETCS functionality will be completely retained as it is only the radio access that is replaced.  The ETCS traffic model can be supported by all the TETRA data services (Short Data Messages, Circuit Mode Data or Packet Data service): e.g. Train - Wayside: Position report Wayside - Train: Response to position report / Movement authority TETRA and Railway Signalling for Safe and Efficient Operation (3) Telecommunications & Train Control Conference August 2014 ERTMS (European Rail Traffic Management System) ETCS (European Train Control System) GSM-R (radio communication system)
  22. 22. Presentation on behalf of the TETRA + Critical Communications Association TETRA also supports CBTC data requirements.  There is NO mandatory radio technology to support the communications of CBTC protection systems. The standard IP interfaces of TETRA are appropriate for that integration .  The CBTC functionality will be completely retained as it is only the radio access that is replaced by TETRA providing Reliability & Availability along the rail line. Flexibility and integration: TETRA technology is flexible and can be seamlessly integrated with other wide or broadband technologies for complementary solutions, e.g. LTE. TETRA and Railway Signalling for Safe and Efficient Operation (4) Telecommunications & Train Control Conference August 2014
  23. 23. Presentation on behalf of the TETRA + Critical Communications Association  TETRA unlike GSM-R has integrated DMO mode included in its standard (without having to integrate another FM analogue radio e.g. for shunting activities). This TETRA DMO mode also provides user with option of gateway repeaters for coverage enhancements.  TETRA is better provisioned than GSM-R to provide seamless handover continuity between cells, because of pre-emption protocols that already exist to disconnect lower priority users as part of TETRA’s emergency call facility.  TETRA has much faster call set-up time as compared to GSM-R. From a safety perspective, a TETRA system would be better suited for an environment where fast response times are critical. TETRA a comparison with GSM-R (1) Telecommunications & Train Control Conference August 2014 GSM-R technology is derived from GSM Cellular technology for public access adapted to a railway environment which is a mission critical environment. Private mobile radio technology such as TETRA was designed from the start for mission critical private radio networks. For example:

  25. 25. Presentation on behalf of the TETRA + Critical Communications Association Future Development As with any technology buy, a technology must have a migration or evolution path to upgrade to meet foreseeable future trends. Obsolescence is a key factor to consider before selecting the most appropriate technology to support any railway communication requirement.  Long life cycle is mandatory for the equipment in a railway environment.  TETRA has been growing up according to the professional market needs and the life cycle of the technology is guaranteed and will continue to offer secure and resilient voice and data communications for mission critical users for many years.  The TETRA standard is flexible and open to allow software application interfaces to be written to the system to meet very railway specific requirements. And it can be complemented by LTE that will provide very high data services. TETRA for efficient and safe rail operations Telecommunications & Train Control Conference August 2014
