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 102 021to 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
