  1. TETRA Data ServicesIncluding (Internet) IP Packet Data Access Ole Arrhenius Nokia

  2. Agenda • Wireless data in TETRA • Applications using different TETRA data services • WAP

  3. TETRA data standards TETRA voice + data TETRA Packet Data Optimised (PDO) Bearer services = data transport: - packet, circuit, single/multislot Peripheral Equipment Interface (PEI)

  4. TETRA data services • 16 bits of information • Individual and group addressing • Standardized values and free values for applications Status • Individual and group addressing • Application use and text messaging • 1=16, 2=32, 3=64, TL=1017 and 2048 bits SDS 1, 2, 3, TL • Internet Protocol • Standard TCP/IP (UDP) protocol layer for applications TETRA-IP

  5. Data services for different needs Great amount of data TETRA IP Often Rarely SDS-TL SDS 2,3 SDS 1 and Status Small amount of data

  6. Wireless data applications Workforce management Unit status, AVL Instructions Information retrieval, inquiries Task related information Identity Vehicles, weapons, fingerprints Maps Reporting Task course and operations Control and monitoring Alarm devices Environmental measurements Field equipment telemetry Surveillance video Still/video image Control rooms IT systems Databases Data networks Instrumentation Portable users Vehicle users Fixed equipment

  7. Status messaging • Remarkable savings in routine voice communication • Improved workforce management Crew 1: "At substation 12" Crew 2: "Free" Crew 3: "Lunch" Status message TETRA network

  8. SDS SDS SDS SDS Short Data Service (SDS) work orders and reporting • Convenient, accurate and efficient communication • Suitable for Short Data (SDS) messaging. Dispatcher Application C&CR Application Application TETRA network Application SDS PEI

  9. Short Data Service (SDS)Automatic Vehicle Location (AVL) • AVL information is transferred with SDS messages

  10. Database e-mail FTP WWW WAP Packet data gives benefits of Internet Protocol and TCP/IP • Shared use of the radio transmission path • Suitable for bursty traffic • Connectivity to the surrounding IT environment - the entire www technology • Support for standard products and applications

  11. TETRA IP packet data Application Application Tetra network Internet Backbone/transmission Company Intranet Control Room Intranet Enterprise Intranet

  12. Intranet Intranet Intranet Data access with TETRA IP database interrogation IP Distribution Core TETRA Enquiry Database Info

  13. Detailed text report 700 characters = 2.8 s Text report + passport photo = 2.8 s + 4 s = 6.8 s Full A4 page report 1700 characters = 6.8 s TETRA IP transmission speed • Data amounts in professional work are quite small • In real life, the transmission speed is faster than a human can read or write • Remember, fast start-up time

  14. TETRA Image Image transmission • Still images or short video clips • Compression methods are effective: JPEG, JPEG2000, MPEG4, MVQ • site of an accident, common view • vehicle damages • control of driving style, incorrect overtaking • incorrect loading • place of crime, common view Original Compressed 15 seconds C&C Room Police Car

  15. TETRA Patient monitoring unit for use in emergency care in mobile environment • Transferring patient related data to the hospital from mobile unit • Measurement of vital signs of the human body • Nursing history by mobility • 12 channel ECG monitored data • Oxygen saturation • Blood pressure • Pulse Doctor Ambulance

  16. Dangerous goods • All dangerous goods have their own unique number based on UN numbering system that is used worldwide • All information in standard format • tradename • prohibited area • potent of goods

  17. SDS Gateway TETRA TETRA in WAP Forum • WAP adaptation initiative to TETRA April 1999 • TETRA was included in WAP v1.2 Dec 1999 • WAP is adapted to TETRA IP and SDS bearers Application WAP Server SDS WAP Server IP WAP=Wireless Application Protocol

  18. Professional TETRA WAP applications • WAP traffic data transaction amounts are quite small (200-500 Bytes), high air interface capacity not needed • WAP needs rapid data service • WAP also provides security layer TETRA ! WAP optimizes air interface TETRA SDS and IP Terminals API Connectivity Network Applications Content API products and WAP Server Operator/Service/Content providers

  20. fax Intranet Internet PABX PSTN email voicemail WAP Unified Messaging Center Voice mail and unified messaging solution • Unified messaging: voice mail, fax and email all in one solution • Similar voice mail solution as in cellular networks • Mailbox access via WAP and internet TETRA

  21. WAP interoperability is assured • Interoperability is about: • clear specifications • developer guidance and education • a reference pool of products • covers all components • Certification process already in place (March 2000)

  22. WAP summary • WAP is a tool to access information • PSS and professional organizations already have database content • TETRA IP and SDS are optimal bearers for WAP • No need for any upgrading in WAP terminals when new applications are taken in to use • WAP includes security layer

  23. TETRA data makes it easy for the application industry • Commonly used network interfaces like IP • MS Windows application Programming Interfaces (API) • Different gateways bring the existing applications visible over TETRA

  24. Conclusions for TETRA data • Data is there for the professional radio users • Data is fast because of rapid call setup times • Brings Internet/Intranet and WAP access to mobile workforce TETRA data is a part of the future
