TETRA and Information Technology, Agenda

• PSS Special needs for Data Applications
• Application type segments
• Data service and application providers
• TETRA Data Services
• APIs, Application Integration to TETRA
• WAP
• Software development steps
• System integration and testing

3
Clearly Defined Open API for Data Services

• Open standards TETRA, WAP, TCP/IP
• Standard and commonly accepted IT protocols
  preferred
• Widely used interface technology like Microsoft
  COM
• Interoperability with existing services and
  networks
• Easy integration, migration and future proof
• Platform for 3rd party products and solutions
• Local and national solutions

Special needs for Wireless Data in PSS

• Content of the service is confidential and
  organization depended
• Existing Command and Control Room systems and
  applications must migrate
• Service usage level is high
• information push from the Dispatcher and status
  messaging
• data access from the field
• AVL systems
• Wireless Data services are time critical
• Service must work in reliable way

5
Information to the Field Forces

• Using world wide standards like TCP/IP and
  Microsoft COM in TETRA interfaces makes possible
• well known and best applications can be used with
  TETRA and Office
• AVL, E-Mail products and text information to
  field forces
• Information to field, enables fast decision
  making
• Police force can purchase and develop new
  application from 3rd parties
• TETRA WAP

Data Access Services

• Needs
• Faster and effective communication, Reporting
• The right information in right time
• Access organization's data stores, Database
  queries
• "Pull" information services
• Information retrieval, Mobile office,
  Client/Server computing
• Users Field Sales, Field Services, Mobile
  Professionals, Delivery professionals etc.
• IP Packet Data
• SDS for application for small data amounts
• 3rd party middleware software products for
  optimize the TCP/IP
• TETRA WAP is good application environment in the
  future

11
Messaging

• Using the TETRA network as extranet/Intranet of
  the organization
• Email
• Fax
• Short Data Messaging
• Special application for PSS communications
• People to people communications
• Middleware products for optimization the TCP/IP
  traffic

12
Embedded Telemetry

• Devices and Control system communicate
  automatically
• TETRA is transmission network
• remote control and monitor
• transmit measurement data
• alerts and information
• Organizations are looking for better and new
  services
• efficiency

TETRA Data Services, Summary

• Status service
• 16 bit integer data, fixed length
• 32768 values free for application use
• Fast delivery with minimum load to radio path
• Group addressing
• Short Data service, SDS
• 4 types of SDS messages. 16/32/64 bits and 126
  bytes.
• Fast delivery (less than 0.5 sec), small load to
  radio path
• Group addressing
• SDS-TL, Transport layer
• IP Packet Data
• Standard TCP/IP protocol layer (winsock) for
  applications
• Fast connection setup
• Economic radio path usage, automatic
  disconnection at inactive periods
• Circuit Mode Data

15
Status Service in the TETRA

• Pre-coded status numbers are transmitted, both
  sides know what numbers means
• 16 bit integer data, fixed length
• 32768 values for application use
• 32768 values reserved for further standardization
• General acknowledgment
• Fast end-to-end delivery with minimum load to
  radio path
• TETRA address space
• Group addressing.
• Call unrelated
• Messaging during ongoing speech call
• Emergency status goes always through

16
SDS Service in the TETRA

• The TETRA standard defines four different SDS
  message types
• SDS--1 Values 0 - 65535 are free for application
  designers. Different PDU (Protocol Data Unit)
  header than in TETRA Status messages.
• SDS--2 32--bit--long messages, all values are
  free for application designers
• SDS--3 64--bit--long messages, all values are
  free for application designers
• SDS--4 messages of variable length
• (1017 bits, 1261 bytes, with advanced link max
  2551 bytes data)
• Address is ITSI address (same as in the voice
  calls)
• Sending SDS to the Groups is possible
• On-Line, End-to-end delivery
• Uses master signaling channel
• SDS-TL (Transport Layer) standard
• basic text messaging protocol for end to end
  acknowledgements

17
SDS-TL (Transport Layer) Services

• end-to-end acknowledgement of message receipt and
  consumption by application
• support for multiple application protocols
• point-to-point and point-to-multipoint message
  transfer
• broadcast message transfer
• SDS-TL Text Messaging will be supported (subset
  of the whole SDS-TL)
• A short report mode (using SDS precoded status)
• negative acknowledgements
• Protocol/encoding not supported
• Destination memory full
• Message received
• A long report mode (using SDS UDD-4)
• four negative acknowledgements
• Destination not registered on system
• Delivery failed
• Unknown destination, gateway, or service centre
  address
• Group address with individual service

IP Packet Data in the TETRA

• IP protocol fits well to bursty traffic (IP
  Internet protocol)
• Enables long session times gt "always on, always
  connected"
• Radio resources used economically
• Connectivity to the surrounding IT world
• Products available in Client and Server side
• Numerous application segments can use IP network
• Future-proof protocol layer (TCP/IP) for the
  applications
• roaming and handover supported
• IP address allocation static or dynamically,
  private and public IP addresses
• TCP/IP Winsock layer for Applications

20
TETRA IP Packet Data Air Interface

• Uses Assigned Secondary Control Channel (ASCCH)
• With 1 timeslot channel gross rate is 4,8 kbits/s
• TETRA provides robust data link
• Retransmissions of entire datagram
• Selective retransmission of corrupted frames
• Windowing (acknowledgement of multiple datagrams
  at once)
• Air interface encryption applies to IP
