  4. Comparison between analogue and TETRA 1G terminal (Aachen Pilot) First Generation TETRA Handportables • First generation terminals no longer in market • Limited processing power and memory • First generation terminals provided simple ‘entry level’ features but: • Had many supplier specific ‘TETRA’ implementations • Limited talkgroup numbers • Limited Static Cipher Key capability • New features difficult to incorporate (e.g. Transmit Inhibit) • Little or no possibility for software upgrades • Poor battery performance

  5. Commercial Examples Public Safety Examples Second Generation Handportables • More processing power and memory • Ability to implement new features by software upgrade • Extended battery life • Reduced size + weight • Capable of: • WAP browser • Hardware support for SIM • Multi-slot data? • Colour Display • Voice Feedback

  6. Public Safety Examples Enhanced Second Generation Handportables • Even more processing power and memory • Physically the same as previous equipment, but often new platform under the skin • Widespread use of better colour screens • Integrated GPS receiver • Enhanced MMI, with larger numbers of groups supported, and better group management • End-to-end encryption supported (may be additional module)

  7. 2nd Generation 2nd + 600g 400g 200g 2003 1997 1998 1999 2001 2002 TETRA Handportable Terminals - size and weight 1st Generation 2004 PAMR Public Safety

  8. Cleartone • DeTeWe/FWK • OTE • Motorola • Nokia • Sepura • Teltronic TETRA Terminal Interoperability • Terminal Interoperability is a key requirement for the vast majority of users • Many TETRA systems currently in operation are supporting terminals from a range of suppliers • Suppliers involved in an active TIP programme • At the last TETRA World Congress in Vienna, November 2004, TETRA interoperability was demonstrated with terminals from the following manufacturers:

  10. Overview • Still a need for mobile and portable terminals • Mainly portables for mobile workers • However cars are still equipped • Need for motorcycle and other specialist terminals in Public Safety • Portables could be personal issue, or picked up from station at start of shift • Public Safety Encrypted radios are secure devices, and need to be treated as such • Most suppliers are now in enhanced second generation terminals

  11. Market Streams NowFuture NowFuture         Commercial PublicSafety             Portable Mobile Basic Terminal User Requirements 1 Handportable Requirement

  12. Battery Technology Typical Battery Life (90/5/5) G2PublicSafety Hours x 1 30 G1PAMR G1PublicSafety 20 Energy Density x 1.3 10 2002 1997 1999 2001 x 2 Year NiCad NiMH Li Ion Battery Life • NiCad batteries not used for some years now • Most portables now use Li Ion batteries • Improvements are in battery capacity and weight, not in extended battery life • Most suppliers offer standard and extended life batteries, to achieve the duty cycle

  13. Mostly Software? Direct Mode Expectation was for a powerful set of DMO functionality • Repeaters, gateways, gateway/repeaters, dual watch Where are we today? • Basic DMO in use, with gateways used to extend coverage • Interoperability was a problem but now a basic TIP • A few manufacturers of gateways and repeaters Still to be addressed • Security • Channel surveillance • SDS-TL • PEI for DMO • Dual Watch • Frequency Efficient Mode

  14. Simultaneous Voice and Data Expectation was for simultaneous voice and data calls • Any combination of single or multiple calls (e.g. voice call and simultaneous data download) Where are we today? • Various ‘pseudo-simultaneous’ services • Voice and SDS/Status • Number of different signalling channels (FACCH, SACCH etc) depending upon the current state of the call • Slower than operation on main control channel • Alternating Packet Data and Voice/SDS • Service Interaction TIP and Test Plan available • Allow suspension of one service to get another

  15. High Speed Data • Expectation was for ‘high speed’ multi-slot data • Back in 1997, the quoted 28.8KBps, using four concatenated timeslots, was being described as being fast….. Where are we today? • Support for circuit mode is limited (no TIP, fewer & fewer Manufacturers) • Single slot packet data well established, typically 4.8KBps max with error correction • For higher speeds in TETRA1, multi-slot data is needed • Multi slot will be available in very near future • Greater processing power will allow portables to do more than on slot • TETRA2, still being developed • TEDS (TETRA Enhanced Data Service) in standardisation • Will be available in a few years, but needs increased channel bandwidths for the higher data rates – spectrum planning

  16. Location Services • User requirement has pushed manufacturers to offer integrated GPS solutions • This includes locating the person, not just vehicles • APLS (Automatic Person Location Service) • ETSI standards being enhanced to include a Location protocol standard - LIP

  17. Upload/download from radio SIM • Re-program of terminal • Download/upload via PEI • Download/upload via TETRA • Download/upload via local (non-TETRA) wireless link • Multiple profile storage in terminal • Widely used • Likely to be standardised solution • Not robust • Security? Personalisation • Portability of personalisation data attractive for • Mobile terminals (personal issue not practical) • Shared terminals (transfer of data between shifts, e.g. telephone numbers) • Replacement and repair

  18. TETRA Terminals Review • Introduction • TETRA Terminal Evolution • Some Key Terminal Issues • Drivers for New Terminal Development • Summary

  19. Drivers for New Terminal Development • TETRA terminal volumes are a small fraction of the GSM market (1-2%) • Manufacturers seeking to exploit synergies with other product lines and technologies • Common software and hardware platforms to reduce development costs • TETRA standards and feature roll-out continuously evolving • Competition in the TETRA market – manufacturers cannot afford to sit back and see their terminals eclipsed by others • Latest trends in GSM and 3G • Colour displays • Polyphonic ring tones • Camera • MMS

  20. ! = Third Generation TETRA Terminals • Current terminal development cycle 18 – 24 months • Higher levels of integration and more MIPs • Class E equalisers? • Multi-mode (TETRA/GSM/UMTS?) operation?? • Enhanced data facilities, including Java • Availability of data-only ‘modem’ units (here now) • Over the Air download and configuration • Will we see PDA type devices with TETRA capability? • TETRA2 Highest speed data (nQAM) not until fourth generation?

  21. TETRA Terminals Review • Introduction • TETRA Terminal Evolution • Some Key Terminal Issues • Drivers for New Terminal Development • Summary

  22. Summary • There remains some functionality to be delivered • Hand portable terminals will continue to evolve to be lighter and smaller • Interoperability is a reality; TIP determines minimum feature profile • Key terminal issues being resolved: personalisation, MMI, RF Sensitive Mode • Short terminal release cycle – this has a real commercial impact • Specialist terminals and peripherals are starting to be commercially available • TETRA Release 2 promises much but commercial reality is still several years away • TETRA offers unique PMR type functionality that is not provided by public cellular networks
