Agenda
• TETRA and public cellular systems
• Comparison with other PMR technologies
• TETRA market
• State-of-the-art technology
• The future
Frequently Asked Questions
• Why do I need TETRA instead of public cellular
networks (GSM, GSM-R, UMTS)?
• Why do you say that TETRA is the winning PMR
technology?
• Is TETRA a mature technology?
• Which are the relations between TETRA and
UMTS?
Group communications
• Point-to-multipoint voice and data including many
supporting features such as
•Unlimited number of included users
•Unlimited site extension
•Dynamic Group Number Assignment (DGNA)
•Late entry
•Talking party identification
•...
Control room and dispatching operations
• Focus on communications between radio terminals
and control room/dispatcher operators
•Call Authorised by Dispatcher (CAD)
•Ambience/Discreet listening
•Dynamic services management
•...
Secure communications
• Multiple security schemes and algorithms
•Authentication of User / Terminal
•Authentication of the Infrastructure
•Encryption:
• Air Interface Encryption
• End-to-End Encryption
•OTAR- Over The Air Re-keying
•Security Management
•Disabling of stolen radios
This is
very confidential!
Communicate also when out of network
radio coverage
• Fully digital trunked (TMO) and direct (DMO) modes of
operation
•Dual watch
•Repeater
•Gateway
• DMO adds fringe or
out of coverage
area communications
• DMO provides
communications within
coverage at times of
capacity limitations
And the professional mobile specific
features continue
• Emergency calls
• Fast call set-up
• Concurrent voice and data
• “Real time” short data services including status
messages
• Further PMR supplementary services: call priority,
access priority, area selection, ...
TETRA features differentiation from
public networks

TETRA and other PMR technologies
TETRA is:
•Digital
•TDMA based
•Open standard
Digital
vs. analogue
• Constant voice quality
• Higher data rates
• Efficient and effective secure communications and
authentication

TDMA vs FDMA
• Bitrate on demand
• Higher data rates
• Simultaneous voice and data
• Simplex terminal for duplex
communications
• One TRX to manage
four traffic channels
TETRA is a real open standard
• TErrestrial Trunked RAdio (TETRA) is an open
standard which is defined by the ETSI to meet the
needs of the most demanding professional mobile
radio users.
•It has been fully accepted by all the European and many other
Administrations.
•ETSI has started the work program for TETRA release 2
Interoperability certification
• The Interoperability Certificate (IOP) assures that
various manufacturers infrastructure and terminals can
indistinctly operate on any TETRA network
•The various functionality tested and approved are summarized in
public tables
•Tests are executed by an independent accredited test house: up to
now Teledanmark (Danish operator)
TETRA and APCO 25
• Project 25 is a Digital Radio Project that involves both APCO and
TIA members, in ANSI/TIA Standardisation
• Project 25
•Phase 1 is 12.5kHz FDMA
•Phase 2 has FDMA (6.25 kHz) and TDMA (12.5 and 25 kHz)
components
• TETRA has been selected early in 2000 as TDMA option for the
phase 2 (IMBE codec and DES encryption)
• APCO 25 and TETRA are the only two digital standards for PMR
originated from international standardisation institutes that are
being deployed across the world

Customer trends
• Public safety and security services
•EUROPE: TETRA is the consolidated open standard technology
for PSS radio mobile systems. Almost all European Countries are
using (or have plans to use) TETRA
•WORLD WIDE: interest is consistently increasing and first
projects are starting in all regions
• Transport and utilities (Civil Users)
•Projects in this segment partially suffered the spectrum issues
for civil TETRA in the past but the solution to these problems is
on the way
TETRA growth outside Europe: China
• On April 2001 TETRA has been adopted
as national standard by Chinese
administration. Most of the allocated radio
channels are in the 800MHz frequency
band
• First tenders for TETRA have already been
issued and assigned for transport (railways
and subway companies) and public safety
applications
• TETRA market growth is envisaged for a
long duration in China
TETRA growth outside Europe: USA
•TETRA adopted as basis of a 4-slot
TDMA system for Project 25 Phase II
•MOU proposal includes use of DVSI IMBE codec,
DES encryption and Phase I FDMA interoperability
•TR-8 formulating committee (TR-8.14) established
to develop ANSI/TIA standard
• TR-8.14 is working on two variants:
•Standard for Public Safety with changes
•Standard for Non Public Safety without
changes to codec or encryption
• Shell Standards in draft form, with ongoing work,
to complete during 2001
• North American TETRA Forum set up, providing
support from users
TETRA is state-of-the-art
