4TETRA 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

Location (AVL)
- AVL information is transferred with SDS messages
10Packet 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

13TETRA 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
14Image 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

15Patient 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

Ambulance
16Dangerous 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
17TETRA 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

WAPWireless Application Protocol
18Professional 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

19Optimisation with WAP
- Optimises user interface for mobile
display/keyboard - Optimises radio path usage
- Provides standard Wireless Markup Language

20Voice 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
21WAP 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)
22WAP 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
23TETRA 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
24Conclusions 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
