  1. 1. TETRA ASSOCIATION Specialised TETRA terminals and Product Compliance Roger Dowling Board Member TETRA Association 9th September 2009 Delhi
  2. 2. TETRA ASSOCIATION Part 1 – Specialised TETRA terminals Extending Coverage of a TETRA Network using Gateways and Repeaters TETRA Surveillance Products TETRA in hazardous environments (ATEX) Part 2  ‐ Product Compliance TETRA Interoperability (IOP)
  3. 3. Basic Requirements of any TETRA Network/Terminal A radio is not just for Voice communications it is a key  operational tool that helps save lives. The key requirements of a TETRA radio terminal are: •Best and most reliable voice communications •Best and most reliable data communications
  4. 4. Extended Coverage For Voice and Data TMO Repeaters  • On frequency repeaters that extend TMO coverage only • Can be expensive and normally are fixed to a location – inflexible DMO Gateways • Provide a link between TMO users and DMO users who may not have enough  RF power to reach the network DMO Repeaters • Extend coverage between DMO users Some terminals can act as both Gateways and Repeaters
  5. 5. What is a Gateway? A Gateway connects users operating in Direct Mode with the Trunked Mode network TMO TETRA Network Gateway DMO Network Coverage Control Centre Extension of a  No TMO Network Coverage Trunked Mode  TETRA Network
  6. 6. Gateway Application Example Users out of network coverage can report their current position to  either their vehicle or to an operator via TMO and to their vehicle  Gateway Alarm indications can report the position of the originator TETRA Gateway TMO Network Mobile Data Terminal PEI SDS Position Report Control Centre AVL/APL System No TMO Network Coverage Location of Remote Users
  7. 7. What is a Repeater? DMO DMO Repeater DMO DMO DMO No TMO Network Coverage A Repeater extends coverage between DMO users Typically a vehicle mobile strategically placed acts as a DMO Repeater to extend communications within a closed group.
  8. 8. Repeater Application Example No TMO Network Coverage DMO DMO DMO Mobile Repeater Extension of the DMO Range in Remote Areas
  9. 9. Hand Held Repeater DMO User ‘A’ DMO User ‘B’ When Direct Mode radios are out of range of each other…
  10. 10. Hand Held Repeater DM ‘Repeater’ DMO User ‘A’ DMO User ‘B’ A Repeater can be used to relay communication between Direct Mode terminals
  11. 11. Users of Gateways & Repeaters Utility companies Fire Services Oil & Gas Public and Private Ambulance Services Police Services Airports Border Guards  Many users now buy Gateway and Repeater hardware enabled radios and add the functionality when needed.

  29. 29. Hazardous Areas Definition of Hazardous Areas Area with possible presence of a potentially explosive atmosphere An explosive atmosphere is defined as a mixture of:  – flammable substances (gases, vapours, liquids, mists  or dusts) – with air – under atmospheric conditions – in which, after ignition, the combustion spreads to the  entire unburned mixture An atmosphere, which could become explosive due to local and/or operational conditions, is called : a potentially explosive atmosphere.
  30. 30. Directive 94/9/EC (ATEX Directive)  • The European Directive 94/9/EC (ATEX Directive) – It covers all equipment and protection  systems to be used in potentially explosive  atmospheres.  – This is an increase in scope compared to  previous national regulations.  • Typical Applications – Fire Brigades – Petrochemical Plants – Fixed offshore platforms – Ports and Airports – Industries (chemical, pharmaceutical, ...) – Mines 
  31. 31. TETRA Equipment for Hazardous Environments Examples of ATEX certification: Products currently II 2G EEx ib IIC T4 available from four II 3D Ex tD A22 IP54 T85°C X manufacturers
  32. 32. Oil and Gas & Fire Services • Pipelines and refineries in Africa, Asia ‐ Middle East, Europe ,  Russia and South America • Fire Brigades in Europe

  36. 36. What is Interoperability (IOP)? • IOP ensures that TETRA equipment from one manufacturer  functions (interoperates) with TETRA equipment from  another manufacturer.
  37. 37. TETRA Association Marketing Group Operator and Users Association - OUA Association TETRA Technical Forum (TF) Security and Fraud Prevention Group - SFPG Rail Forum Regional/Geographic Forums
  38. 38. IOP Teams Technical Forum (TF) • Manages Interoperability Process • Creates TIPs (TETRA Interoperability Profiles) and Test Plans Any Member of the Association is welcome to join Operator and Users Association - OUA • Creates usage scenarios for features  • Sets IOP TETRA feature priorities Not open to manufacturers
  39. 39. Do I need Interoperability? • One Supplier – makes life easier for operator & user – the supplier ensures that infrastructure & terminals  operate together? – No one supplier provides every type of terminal – Dependent on one supplier’s development timescales – Features not always released on infrastructure & terminals  at same time – Locked in – watch the price of enhancements  When you buy your cell phone – do you ask who supplied the network?
  40. 40. Benefits of an open multi-vendor market • User benefits – wide choice of compatible terminals – 10+ suppliers – specialised products for special needs – continuous and fast product development & innovation – genuine competition, hence lower prices (c.f. P25) – reduced dependency on a single supplier • Industry benefits – larger market, greater volumes – increased possibility to invest – faster product creation – Market longevity The TETRA Association created the IOP certification process to guarantee an open multi-vendor market
