Title: TETRA Data Services Including Internet IP Packet Data Access


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
  • 116, 232, 364, TL1017 and 2048 bits

SDS 1, 2, 3, TL
  • Internet Protocol
  • Standard TCP/IP (UDP) protocol layer for
    applications

TETRA-IP

Status messaging
  • Remarkable savings in routine voice communication
  • Improved workforce management

Short Data Service (SDS) work orders and
reporting
  • Convenient, accurate and efficient communication
  • Suitable for Short Data (SDS) messaging.

Location (AVL)
  • AVL information is transferred with SDS messages

10
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

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
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

15
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
  • trade name
  • prohibited area
  • potent of goods

17
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
WAPWireless 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

Optimisation with WAP
  • Optimises user interface for mobile
    display/keyboard
  • Optimises radio path usage
  • Provides standard Wireless Markup Language

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
