4Market OverviewRelease 1 TETRA is almost completeGrowth of Wireless communicationImpact of Internet & 2.5/ 3G on TETRA marketNeed for TETRA enhancements is driven by new applications, e.g requiring higher data speeds.
5TETRA Release 2 Services & Facilities Not a new Standard but enhancement of the various aspects of TETRA Release 1, viz.Air InterfaceSpeech CodingSIM EvolutionRoaming & Interworking with CellularHigh Speed Data
6Air Interface Enhancements Extending RF RangeReducing Call set- up Time and End-to-end DelayIncreasing in Subscriber CapacityExtending Battery LifeReducing Terminals Size & Weight.
7Roaming & Interworking Codec and SIM Roaming to GSM/ GPRS SystemsRetrieval of WAP ApplicationsRetrieval of SMS MessagesUse of UMTS/ 3G SIM Technology for Improved InterworkingUse of UMTS/ 3G Codecs to Avoid Double Voice Coding.
8TETRA R2 - High Speed Data IP driven requirement for higher-speed packet dataTwo-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)
9TETRA Advanced Packet Service - TAPS An Overlay SystemNeeds New Infrastructure & TerminalsData rates up to 384 kbps200 kHz Channel RasterBased on Adaptation of GPRS and Classic EDGE TechnologiesStandard Publication expected in early 2002.
10TETRA Enhanced Data Service - TEDS An Integrated SystemTechnology selection based on User Requirement Specification from EPT Working Group 1Four candidate technology currently under consideration in EPT Working Group 4Technology selection expected during Q1 2002
