Conclusions
Data services and
security are
discussed in
other
presentations
Mission critical needs
Guaranteed service
- under normal conditions
- during incidents
- planned capacity for emergency handling
- semi-duplex (only one channel per group per site)
Fast group communications
- x00 ms set-up time
- good dispatching
- dynamic group management
Specific functionality
- emergency calls (pre-emptive)
- security
- monitoring, status messages
Unique Powerful Package
Four in One:
–
–
–
–
Group voice & dispatch
Mobile telephony
Messaging
IP data
OPEN HERE
Uncompromised security
Capacity for nationwide shared networks
TETRA standard Release 2 will strengthen
the package with High Speed Data + few
other functions
Basic PMR Voice Services (and more)
Excellent voice quality of ACELP codec
Group calls
–
–
–
–
Wide area groups up to nationwide
Fast call set-up
Virtually unlimited number of talkgroups
Economic use of resources
Individual call (semi-duplex)
– Direct call i.e. press and talk
– Hook call i.e. answer when it rings
Mobility management and fast cell reselection
Basic Mobile Telephony
Individual call (full duplex)
– Radio to radio
– PSTN/PABX/ISDN
connectivity
Mobility management and fast
cell reselection
Before TETRA this was not
self-evident
Advanced PMR Voice Services
Pre-emptive Priority Call (PPC, emergency call)
Call queuing when resources busy
Priority Call up to 16 priority levels (PC & PPC)
Late Entry (LE)
Ambience Listening (AL)
Call Authorised by Dispatcher (CAD)
Discreet Listening (DL, monitoring of calls)
Dynamic Group Number Assignment (DGNA)
Talking Party Identification (TPI)
Advanced Mobile Telephony Services
MS-ISDN numbering to address the whole world
Short numbering schemes
Modern PABX facilities such as
–

–
–
Calling party identification
Barring of calls (incoming & outgoing)
Call forwarding
Call Waiting
Billing and Customer Care systems/interfaces
Text messaging

Data
Service
TEDS
comes in
Release 2
Status service
– efficient, real time
– group and individual addresses
Short Data Service, SDS
– text messaging
– GPS position data
– group and individual addresses
IP packet data
•

•
•
file and image transfers
database access
reporting
WAP, web browsing
Circuit switched data
End-to-end applications for end-user needs
TETRA has created new type of application supply
Manufacturers’ development partnership
programmes gather even hundreds of software
houses
A. Horizontal applications common with
commercial mobile data business
– Positioning, databases, email etc high volume
applications
B. Very specialised fit-to-purpose segment specific
applications
– Command & control, telemedicine, telemetry, …
Other Services & Facilities
Transmitter Inhibit
Direct Mode operation (DMO)
– Traditional
– Gateway
– Repeater
Air-Ground-Air (was part of Release 2)
Location Information Protocol (LIP) (was part of Release 2)
Fall-back operation of Base Stations
Network Interfaces for Telephony, Data, Internet,…
Command & Control Systems, Network Management, etc.
Full security (discussed elsewhere)
Key differentiators of TETRA vs others
Versus Cellular
Versus other PMR
•Fast response group calls
•Mission critical dispatching
•Availability for mission critical
•Full duplex
•Cell handovers
•TDMA capacity
•Spectrum efficiency
•Voice + data truly in use
•Multi-vendor market
•Cost benefits
•Fast innovations

Daily use
Under emergencies
Capacity of semi-duplex
DMO, BS fall-back
•Full security
– (mutual) authentication
– Air & end-to-end encrypt
– Disabling of radios
•Features: PPC, LE, Al, DGNA
– Compare the handsets for
GPS, color display, WEB,
WAP, JAVA, …
Sharing a network
Now common practice with TETRA in
Public Safety
– Requires VPN and controlled privacy
– Services and parameters per user
organisation
– Fleet & service management per user
organisation
Leads to big savings in CAPEX & OPEX
Leads to nationwide high-capacity
networks
– TETRA has shown that it can perform
TETRA OK for mission critical?
Guaranteed service
