4. Data – Your competitive edge
It’s not just about voice, data communications can add value to your operation whether it is business critical or mission critical.
Real-time information provides the vital link needed to make better decisions and operate more efficiently.

5. Benefits of Data
What are your top most repeated routine tasks and processes ?
Are they automated?
If not could automation save time and ensure predictability?
Use an application approach to support your existing processes
Streamline work and present the information needed at each step in operations automatically.
This will not only provide streamlining of your workflow, but will also help enforce processes and ensure quality.

Concurrent voice and Short data (always available)
Available in Trunked Mode, Direct Mode and Gateway Mode (always available)
Secondary Common Control Channels (dedicated capacity)
Individual and Group messaging
Concatenation of text messages
Very fast response times (low latency)
Priority services

12. TETRA 1 - PACKET DATA Single Slot Packet Data
The basic IP data service in TETRA 1
Multislot Packet Data increases bandwidth up to 4 times
Combining up to 4 single slots in one packet data channel
Dynamically change the number of slots as voice load varies
Co-existence of single and multi slot packet data
A Multi slot radio can operate on a single slot channel if necessary
Handover seamlessly between sites
Handover seamlessly between PD and TEDS

13. TEDS -Tetra Enhanced Data Service
As seen from the user terminal and a network-connected server, TEDS is equivalent to the SSPD and MSPD TETRA 1 services. The differences are limited to the radio channels and air interface protocols.
TEDS has the same TDMA FDD structure as Tetra 1 with 4 time slots per channel
Two modes
Conventional Access: Fully integrated with existing TETRA, uses existing TETRA control channel;
Direct Access: Allows control channel to be provided on TEDS
TEDS characteristics:
25, 50, 100 or 150 KHz Channel Bandwidth
8 subcarriers per 25 KHz; 2.7 KHz apart
4QAM, 16QAM or 64QAM modulation

15. TETRA Data Summary
Tetra supports comprehensive set of data services capable of supporting a wide range of mission & business critical data applications

16. Introduction to TETRA Location Technologies

17. Can TETRA help GPS Enabled Options
Most TETRA Hand-Helds
Most TETRA Mobiles
Most TETRA Gateways
Some products also support Glonass and other location standards
The answer is yes!
GPS is an option in most TETRA radios today.
It is integrated into the products and optimised in terms of power consumption, performance and accuracy.

18. Can TETRA help 2 1 1 2 GPS for outdoor localisation
There are also systems available on several TETRA radios that are independent of GPS and are suitable for use as indoor location systems or where GPS coverage is poor.
E.g. Dense building environment
Shopping Malls
Factory complexes
Office buildings Etc. 1
GPS for outdoor localisation 2
Radio BEACON for indoor localisation

19. Location Accuracy Do I really know where my user is ? High Accuracy
Low
Accuracy
High
Accuracy
Knowing a location is only part of the story, it is vital to understand how accurate it is. Users are not tied to roads (SatNav)
Accuracy could be the difference in responding in time or not.
Visualisation systems need to be able portray the accuracy to aid decision making
Knowing accuracy is just as important as knowing position

20. How can TETRA be utilised
TETRA services allow use of SDS messaging for transmission of location data:
EN : TETRA Voice plus Data (V+D), part 2:
SDS4 and SDS-TL delivers variable length messages to 2047 bits(255 bytes)
GPS location data is provided in the NMEA formats, GLL, GSA, GGA etc.
Typical GLL mesage could contain as much as 48 bytes of data!
Terminal Manufacturers support compact location messages to minimise traffic
Location Information Protocol –TS , TTR001_19
Specifies the effective use of network by using compact message formats
Typical message (compared to GLL) is 11 bytes long

21. Location Information Protocol
LIP is a TETRA air interface optimized application layer protocol
LIP can utilise the SDS-TL Service or the TETRA Packet Data Service
LIP is location determination technology independent
LIP can support a wide variety of location applications
LIP optimises usage of air interface resources
LIP is the TETRA standard for Location reporting and control

22. Location Information Protocol
Optimization considers both message size and the number of messages
Message size is a compromise between the number of bits available and user requirements
Two types of location report are available with LIP:
Short location report
Long location report

23. Location Information Protocol
Short Report
Time Elapsed
Longitude
Latitude
Position Error
Horizontal Velocity
Direction of Travel
Reason for sending
Long Report
Time of Position;
Longitude;
Latitude;
Location Circle with Altitude
Horizontal Position Uncertainty;
Location altitude;
Horizontal velocity;
Direction of travel extended
Reason for sending
The Short Report has a smaller number of elements and with restricted resolution for some of them, the Long Report provides more flexibility and resolution, but a longer message length

24. Location Information Protocol
Reason for sending codes
Emergency condition is detected
Immediate Position Request
Maximum reporting interval
Maximum reporting distance
Power On

Status
Transmit Inhibit Mode ON
Transmit Inhibit Mode OFF
System access (TMO ON)
Enter service (after being out of service)

26. Location Information Protocol
Over the air control of reporting parameters
Basic Location Parameter
Add/Modify Trigger
Remove Trigger
Location Reporting Enable/Disable
Immediate Location Report
Location Reporting Temporary Control
Control is a very important part of APLS, being able to control how and when reporting is done, will determine how successful and useful an APLS system is.

27. TETRA - Meets the requirement

GPS enabled, indoor solutions
TETRA provides an interoperable standard
Location Information Protocol
TETRA provides configurable control
Timed, Distance, OTA control, Why, When, Where, efficiently
Improves resource usage and enhances Safety
Improves response time, Selection of most appropriate resource
