1. 1 INTEROPERABILITY (IOP) FOUNDATIONS FOR THE FUTURE By Kevin Swann Business Development Director

2. Slide 2 Objectives: Paradigm shift in choice  TETRA: - solid foundations - not the end goal - need for future flexibility  Two areas of software IOP: - bank end - front end  Rise of software importance: - key to the future  Choice of hardware v’s choice of software in : –handsets / mobiles –base stations / repeaters –networks / infrastructure –ISSI

3. Slide 3 TETRA – IOP  Back End - I.P - SIP & RTP

4. Slide 4 A. IOP Back End  RNC  NIF  PSTN GATEWAY  ISSI/ISI  KMS  OTAR  FIPS

5. Slide 5 TETRA BACK END IOP  APCO P25, DMR & SDR  WCDMA or GSM / GPRS  Secure TETRA through ISSI/ISI FIPS with codec module? OTAR, KMS

6. Slide 6 B. Front End (ignore operator issues)  Mobile Phones Analogue UK GSM 900 GSM 1900 AMPS USA GSM 1800 Duelband IOP CDMA Triband IOP Hardware/SoftwareHardware/SoftwareHardware/Software 80% / 20%35% / 65%20% / 80%+ Quadban IOP

7. Slide 7 Front End – Digital PMR / PAMR / LMR  TETRA TIPS → Tetra II (back compatible)  APCO P25 (backward compatible to analogue) PIPS / PCP’s APCO P25 II  Europe - DMR (possibly USA ++) - DPMR  Japan – TETRA – Like but not IOP

8. Slide 8 Military Requirements:  Supreme Security  Home Land IOP  Multinational IOP  TETRA / APCO Features

9. Slide 9 Answer = Software Defined Radio (SDR)  SDR waveforms are key  Implement TETRA and APCO P25 & DMR onto SDR platforms  Then unique waveforms for special requirements

10. Slide 10 To Action This:  Powerful hardware platform  90%+ of radio integral value = software  New waveforms continuously  STRUCTURE OF SOFTWARE ESSENTIAL

11. Slide 11 Core Service Means:  Upgradeable software  Fully exercisable software  Win 32 platform  Portability host  SDR future possible  Built upon TETRA foundations

12. Slide 12 Summary:  Today the choice of system and product is switching from hardware centric to software centric  IOP is a pre-requisite  Future planning is essential  Build TETRA NETWORKS WITH CONFIDENCE but at every stage think SOFTWARE IOP
