4. 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.

5. 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

6. 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.

7. 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.

8. 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)

9. 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.

10. 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

11. 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

15. 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
