Why should TDMA operators invest in 2nd generation wireless data solutions?
The first developing expertise in 2nd generation wireless data solutions will be the winner with 3rd generation wireless data solutions. 3rd Generation 2nd Generation
Cellular Data Market Forecast* (1/3) • US • The total number of cellular data users in the US will increase from 1.9 million in 1998 to 28 million in 2003. • The proportion of all cellular users using data services (messaging, information services, or remote access applications) will increase from 2.7% to 21% over the period. • By 2003, US cellular data revenues are expected to reach US $2.6 billion. * Strategy Analytics, December 1998
Cellular Data Market Forecast* (2/3) • Western Europe • The total number of cellular data users in Western Europe will increase from 3.5 million in 1998 to 51 million in 2003. • The proportion of all cellular users using data services (messaging, information services, or remote access applications) will increase from 4% to 25% over the period. • By 2003, Western European cellular data revenues are expected to reach US$7.4 billion. * Strategy Analytics, December 1998
Cellular Data Market Forecast* (3/3) Messaging • SMS text messaging • E-mail notification • Full or partial E-mail transmission Information Services • Delivery of content (e.g. weather, sports, banking) Remote Access • Company database access (LANs, Intra/Extranet) • WWW browsing • Personal banking and mobile commerce transaction-based applications Fixed Applications • Telemetry/remote monitoring • Point of sale applications * Strategy Analytics, December 1998
TDMA Data Services - Operator Value • Capture wireless data market share $$$ • Build operator’s brand image (new services, Internet Access, …) • Limit churn • Build competence in data services deployment • Information collected during commercial life of 2nd generation data solutions will be an invaluable source for deploying 3rd generation data solution (traffic, capacity, pricing models, marketing, …)

MSC PSTN DCE DTI TDMA Digital Data and Fax Service • provides a circuit switched data access over the Digital Traffic Channel (DTC) air interface • supports a maximum uncompressed user data rate of 9.6kbps • supports data compression over the air interface (V.42bis) • interworks with all popular standard landline modems and fax protocols (e.g. Data: V.34, V.32bis, … Fax: V.29, V.27ter, …) • provides data privacy over the air interface (encryption) • supports automatic roaming • supports seamless handoff
System Requirements for Digital Data and Fax • Mobile supporting IS-130, IS-135 and IS-136-A required (Ericsson T18d) • Digital base station required (884, 882D, 882DM) • TRAB2 (or "higher”) located in the MSC • DTIs required in each MSC providing the Digital Data and Fax service • IS-737 Inter-node (MSC-HLR) signaling required (changes to IS-41-C to support Circuit Switched Data and G3Fax) • Data encryption requires that the Authentication Center shares the SSD with the MSCs • For mobile terminating calls from PSTN, Ericsson supports Two Stage Dialing in the MSC.

Data Transmission Interworking (DTI) - Overview (3/5) • RPBU: Regional Processor Bus Unit. • Connects the parallel RP bus to the DTI for RP bus redundancy • PRO20: This is the Regional Processor Device (RPD) • Stores the code for the TR PBA • Performs surveillance of the HW • Gateway for signaling between the Central Processor (CP) and Device Processors (DP) of the TR PBA
Data Transmission Interworking (DTI) - Overview (4/5) • GSIB: Group Switch Inter Bus. • Provide two DL-2 connections to the Group Switch (GS) • Interface between PRO20 and TR PBAs • TR PBA: Traffic Printed Board Assembly • Contains the Device Processors (DPs) which perform the interworking functions.
Data Transmission Interworking (DTI) - Overview (5/5) • A fully equipped DTI magazine has 8 TR boards • Each TR board can handle 4 calls • For full redundancy, 2 DTI magazine are needed • The number of DTI magazines is only limited by the number of available RP bus addresses (max 1024)
