Market Overview Release 1 TETRA is almost complete Growth of Wireless communication Impact of Internet & 2.5/ 3G on TETRA market Need for TETRA enhancements is driven by new applications, e.g requiring higher data speeds.
TETRA Release 2 Services & Facilities Not a new Standard but enhancement of the various aspects of TETRA Release 1, viz. Air Interface Speech Coding SIM Evolution Roaming & Interworking with Cellular High Speed Data
Air Interface Enhancements Extending RF Range Reducing Call set- up Time and End-to- end Delay Increasing in Subscriber Capacity Extending Battery Life Reducing Terminals Size & Weight.
Roaming & Interworking Codec and SIM Roaming to GSM/ GPRS Systems Retrieval of WAP Applications Retrieval of SMS Messages Use of UMTS/ 3G SIM Technology for Improved Interworking Use of UMTS/ 3G Codecs to Avoid Double Voice Coding.
TETRA R2 - High Speed Data IP driven requirement for higher-speed packet data Two-track approach adopted - TAPS and TEDS, in order to meet conflicting market needs: - of PAMR Operators for Rapid market deployment (overlay TAPS) - for backward compatibility (integrated TEDS)
TETRA Advanced Packet Service - TAPS An Overlay System Needs New Infrastructure & Terminals Data rates up to 384 kbps 200 kHz Channel Raster Based on Adaptation of GPRS and Classic EDGE Technologies Standard Publication expected in early 2002.
TETRA Enhanced Data Service - TEDS An Integrated System Technology selection based on User Requirement Specification from EPT Working Group 1 Four candidate technology currently under consideration in EPT Working Group 4 Technology selection expected during Q1 2002
Findings from Questionnaire - HSD TEDS Mandatory requirements Backward compatibility Service flexibility Security compatibility As marketable as Release 1 Other important requirements Ease of Infrastructure upgrade Minimal need for extra B/Ss Flexible upgrade to 400kbps Efficient use of spectrum Ease of MS upgrade

TETRA Release 2 Applications - Technocop
video camera attached to the personal weapon CIS using new antenna technology including an in-built GPS batteries and the support system personal comm.. & info. pack visor with head-up display protective clothing, with built-in telepresence system, i.e.. sensors monitoring chemical, RF or radiation attack
Present Situation Set of TETRA Release 2 User Requirement Specifications (URS) has been approved and issued as Technical Report TR to all the EPT Working Groups User Workshop has been organised in order to resolve conflicting requirements for HSD Continued liaison between WG1 and other Working Groups is essential to achieve the right balance and the successful outcome
