Agenda
• Wireless data in TETRA
• Applications using different
TETRA data services
• WAP
TETRA data standards
TETRA voice + data
TETRA Packet Data
Optimised (PDO)
Bearer services
= data transport:
- packet, circuit, single/multislot
Peripheral Equipment
Interface (PEI)
TETRA data services
Status
• 16 bits of information
• Individual and group addressing
• Standardized values and free values for applications
SDS 1, 2, 3, TL
• Individual and group addressing
• Application use and text messaging
• 1=16, 2=32, 3=64, TL=1017 and 2048 bits
TETRA-IP
• Internet Protocol
• Standard TCP/IP (UDP) protocol

TETRA network
• 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.

Automatic Vehicle Location (AVL)
• AVL information is transferred with SDS messages
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
Detailed text report
700 characters = 2.8 s
• In real life, the
transmission speed is
faster than a human
can read or write
• Remember, fast
start-up time
Full A4 page report
1700 characters = 6.8 s
Text report +
passport photo
= 2.8 s + 4 s = 6.8 s
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

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
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
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

WAP=Wireless Application Protocol
Professional TETRA WAP applications
• WAP traffic data transaction amounts are quite small (200500 Bytes), high air interface capacity not needed
• WAP needs rapid data service
TETRA !
• WAP also provides security layer
WAP optimizes air interface

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

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)
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
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
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
