  1. TETRA (CERN’s Safety Radio Communication Network) Speaker : Aurélie PASCAL IT-CS Tetra forum 7th of February 2013

  2. TETRA Infrastructure Components of a TETRA Network : DMO Direct Mode Operation SwMI = Switching and Management Infrastructure Network Manager Tetra Base Station (TBS) DMO Gateway/Repeater TMO Trunked Mode Operation TBS Gateway PABX/GSM Base stations controller Dispatcher Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 2

  3. TETRA @ CERN FREQUENCIES :TETRA (Terrestrial Trunked Radio) for European market (except Public safety services) works in the bandwidth : 410-430MHz VOICE CAPACITY:17 simultaneous group calls (TDMA Multiplexing) / 500 devices • Scalable to many DATA CAPACITY: • Short Data Service : SDS • Packet Data Service : maximum data rate 19.2kb/s High resiliency: • Backup of eachactive equipmentand interconnections • Redundant TETRA coreequipmentlocatedon different sites Interconnection with PABX : ISDN (2 redundant gateways)  Consuming of frequencies, reserved to heads of the Fire Brigade Relay of Swiss and French TETRAPOL frequencies : • Strong cooperation with Geneva Police, Customs, Swiss and French Public Safety services Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 3

  7. TETRA Calls Standard group call : Guard LHC8 One virtual group of communication Guardgate B CSA Dispatcher Half-duplex call Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 7

  8. TETRA Calls Dynamic group call : One group of communication Contrôle room EXCR CSA Fireman Intervention Area Fire Brigade Dispatcher Electrical piquet Fireman Half-duplex call Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 8

  9. TETRA Calls Individual call : Electrical piquet Half-duplex call TI Dispatcher Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 9

  10. TETRA Calls :Emergency issue at surface L1 (1 575,42 MHz) & L2 (1 227,60 MHz) TETRA BS SDS : GPS positioning DISPATCHER / FB Emergency call or Lose of verticality SDS : last known GPS positioning Accuracy ~ couple of meters Alarm& SDS received and automaticindividual call established Dedicated IP Network User entered in a building with TETRA coverage Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 10

  11. TETRA Calls :Emergency issue in underground facilities Infrastructure for Indoor localization not yet ready Alarm & SDS received and automaticindividual call established SDS: positioning Emergency call or Lose of verticality Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 11

  12. Example in LHC DISPATCHER / FB 2. Whencatching the ID from the beacon, the terminal forwardsits location to the Dispatcher Workstation at the Fire Brigade 2 3 1 3. When incident : lose of verticalitydetected or emergency buttonpressed emergency SDS sent to the Fire Brigade Dispatcher and individual call established 1. The Beaconlocated in an alcovesendsits ID through a remoteantenna to TETRA terminal Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 12

  13. Surface radio coverage Lose of communication due to forest Base Station Repeater Lack of coverage due to relief Software: ProManfrom AWE Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 13

  14. Indoor radio coverage • LHC experiments, LHC, SPS, PS, Booster, Linac tunnels… are covered with TETRA services but few minor issues are still to fix: • in LHC6 and LHC8, in the middle of the arc section, short area where the signal strength is quite low and communications may be lost. • SPS6 section of tunnel (from the middle of section SPS5-SPS6 to the middle of section SPS6-SPS7) is not yet covered by TETRA. These issues will be fixed during LS1 • Some areas are not covered for now: • The North area : tunnels TT81, TT82, TT83, TT84, TT85, TDC85 • The transversal galleries in PS complex Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 14

  15. Support / Maintenance Infrastructure: • monitored 24/7 via the Computer Center over Spectrum • no need for specific software tools • 1st level of maintenance doneby the First-Line team • 2nd levelof maintenance performed by CERN • 3rd level of maintenance performedby ourcontractor3T Terminals: • Spare parts, repairingand configuration managed by IT-CS for allterminalsthroughourcontracts • 1st batch provided by CERN • For furtherneeds, canbeboughtatCERN’s stores • Online training and practical one (Firebrigade) on radio delivery Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 15

  16. 2013 Planning January:TETRA system operational for CSA & firemen! First semester: • Deployment of Indoor Geolocalisation solution in one Arc section of the LHC and one Experiment • Installation of mobiles in firemen’svehicles • Distribution of terminals (Experiments, piquets…) and trainings • ESD distribution in all sites and new batteries for 4h of autonomy • Microwave Backup linkbetween the 2 main BS  coordination between ARCEP and OFCOM for the allocation of the frequency And…: • Deployment of the Indoor Geolocalisation solution in LHC, SPS, PS, Booster, Linac.. tunnels, Experiments and critical areas (Computer Center…) • Development of a new fullyintegrated software platform ILDA (Indoor Localisation and DispatchAdd-On) Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 16

  17. ILDA The Integrated Localisation and DispatchAdd-On (ILDA) is a client-server system, withdedicatedaccounts and specificpriviledges, whichwillintegrate: • The display of the localisation of TETRA radios (via GPS or Indoor Localisation System) on a fixedgeographical area or for a fixedlist of talk groups • The Dispatching featureswhichwillenable to establish calls and send SDS messages to defined radios through a Phonebook • An incident mode reserved to Firebrigadewithwiderfeaturessuch as direct interaction with the TETRA radios displayed on the maps (calls, SDS sending, selection of multiple radios to createdynamic group of communication…), a tracking mode, search of a specificmap (interconnectionwith GIS portal), transmit inhibition of a radio…, for which all actions willbelogged • An interconnectionwith CSAM centralizelevel 3 alarms: TETRA emergency alarms Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 17

  19. Underground radio coverage / issues LHC8: Lose of communication in the middle of the section LHC6: Lose of communication in the middle of the section Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 19

  20. Underground radio coverage / issues Experiments: the emergeny exits to access the PM lift, closed to the « trémie », are not coveredyet SPS6: No TETRA coverage Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 20

  21. Underground radio coverage / issues PS: No coverage in the transversal galeries nor in the chicane of door 102 Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013 21

  22. Indoor geo-localisation : available solutions • STProtect: • SYSOCO & SEPURA partnership • Beaconusing 868MHz frequency • Receiverintegratedinto the STP8000 terminal • Advantages: • Solution alreadycommercialised and evenbetter by SEPURA (recognizedplayer on TETRA market) • durabilityof the solution • Drawbacks: • Receiver not yetintegrated in the STP8X (ATEX)  on going • The beaconmayneed to beadaptedto enable a remoteextendedantennaand an externalPower Supply Aurélie PASCAL IT-CS / TETRA Forum 07-02-2013
