TETRA market positioning
TETRA Indian Conference

A. PMR or Cellular technology?
Cellular subscribers count in billions.
Why not to use their cool handsets?
Mobile markets overviewMobile markets:A Cellular telephony B Professional Mobile RadioC Dedicated mobile data networks D Broadband WiFi/WLAN etc non-licensed
Mobile mass market trendsCellular mass market enjoys huge growthCellphone replacing fixed phone lineConvergence of voice & data: GPRS, 3GConvergence of telecomms & media/entertainmentVoIP/Push-to-Talk applicationsDedicated mobile data networks disappear
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
Cellular system cannot meet these requirements
- Neither can Push-To-Talk over cellular (CDMA/GPRS)
Cellular system cannot meet these requirements
- Neither can Push-To-Talk over cellular (CDMA/GPRS)
Professional users need own PMRThey must have the best service during emergencies
They need faster call set-up than cellular or PTT over cellular can offer
Cellular PTT systems need too many channels for big talkgroups – PMR uses semi-duplex
Their dispatchers need powerful functionality
B. Okay, we need PMR. What technology?
A look at market dynamics and technical offering of two PMR technologies
Market trends in radio
Shared multi-agency networks
Increased security requirements
Increased use of mobile data
From voice to combined voice & data
Increased telephony connectivity
Data and text messaging
Seamless nationwide service coverage
Need for international cooperation
Need for better radio spectrum efficiency
Overview of 2 digital PMR standards
TETRA – defined by the European Telecommunications Standards Institute
Project 25 – defined as joint project of U.S. user (APCO, NASTD), government and
industry (TIA) organisations
Standardisation/market approach
Project 25Strict Public Safety focusFocus on economic rural
coverage and working in limited spectrum
Backward compatibility with analog FM radios
Voice centric services, data often in separate network
U.S. centric standardSpectrum split and
fragmented: VHF, UHF, 800 …
TETRADesigned to meet the needs of
various user groups – Shared multi-agency PSS– Smaller private networks
Designed to support higher capacities
Combining voice + data in same network from the beginning
International standard from the beginning
Harmonised radio spectrum for European emergency services
Market differences
Project 25Single supplier dominance
Interoperability still under planning
Leader in U.S. PSS market
Individual contracts in Asia-pacific & Latin America
Handset prices even at 4000 – 5000 USD level !
TETRAStrong multi-vendor focus
Working interoperability certification
True multi-vendor experience
Continent wide leader in Europe and Asia
Latin American contracts
Much lower equipment prices due to working competition
Maturity of standards
Project 25Many different paths triedConventional 12.5 kHz FDMATrunked 12.5 kHz FDMA –
trunking protocol came later than products
6.25 kHz FDMA – never implemented in products
TETRA-like 25 kHz TDMA -failedNow trying 12.5 kHz TDMA – very
slowlyNew 25 kHz TDMA proposal filed
TETRATrunked 4-slot TDMA grom the
beginningIn TETRA standards many things
were completed years ahead of Project 25:
Intersystem Interface, roaming support
Authentication, air interface encryption
full duplex, handoverssupplementary services to one-to-
one calls
Technical 1: FDMA - TDMA
Project 25 - FDMATraditionally assumes wider
coverage and lower capacity
Benefits from high power mobile radios ( 10 to 30 W and even more)
Expensive when number of channels becomes high
Trend towards higher user densities poses challenge
Trend towards handsets dilutes the coverage benefit
TETRA - TDMATraditionally assumes smaller
cells and higher capacityCan handle high capacity at lower
costSpectrum efficientEasy full duplex, simultaneous
voice + dataIn handset use on par in terms of
coverage (uplink!)Improvements in TDMA BS
receiver technology and multi-receiver diversity promise equal cell range
Technical 2: Functionality
Project 25Still only half duplexNo handover signallingSupplementary services now under
debateDTMF now debatedVery little IP data seen in neworks
still todayText messaging still now debatedThe new debated features may
come only to the yet noexistent TDMA standard, if even in that ...
TETRAAlso full duplex from the
beginning
Handovers during call
Supplementary services related to one-to-one calls
DTMF signalling long ago
IP packet data in use long ago
Text messaging from the beginning
Much faster feature roll-out (due to competition?)
Technical 3: Networks
Project 25Idea of international co-
operation not visible in standards
Inter-Subsystem Interface standardisation still ongoing
Strong pressure from users asking for “interoperability” – in long term this may improve the standards
TETRADesigned for cross-border
operation, ISI standard
Designed for international traffic, numbering, country codes
Implemented efficient VPN support for multi-agency sharing
TETRA network can be nationwide homogenous seamless entity - today
Radio terminals
Project 25High output powers
available, tens of watts
Quite many manufacturers showing handsets in exhibitions
But still the U.S. price of encrypting handset is 4000 to 5000 USD
TETRAHave supported full duplex for years
Smaller size & weight
Innovations like integral GPS, 65 000 color display emerged
WAP and web browsers built in
Handsets are preferred
And the handset sells at 500 to 1000 USD
Competition is driving innovation and cost efficiency
Speed of innovation
Who else can do this – TETRA already does:
Which other PMR technology delivers handsets with integral GPS receiver today?
Which other PMR technology delivers handsets with 65 000 colour display today?
Which other PMR technology delivers handsets with web & WAP browsers today?
Quick questionnaire in TETRA World Congress 2005 revealed some 30 new TETRA terminal models being launched during the last 3 years
Only open competition can boost this amount of handset innovations and R&D investment
Multi-vendor interoperability
TETRA is the first PMR technology that created a truly open multi-vendor market
Benefits of open multi-vendor marketUser benefitswide choice of compatible certified terminals
specialised product for special needs
continuous and genuine competition
less dependency - lower risk of market disturbances
Industry benefitswider market, bigger volumesmore possibility to invest – faster product
creationlonger lifetime of market
TETRA MoU Association runs the IOP certification process to guarantee open multi-vendor market

Summary, TETRA vs Project 25
TETRA makes major difference in multi-vendor support, certified interoperability and open competition
In voice group call services both technologies offer about the same level of services
In one-to-one calls related services TETRA clearly leads
Use of data much better exploited in TETRA networks - IP data is in operational use
Clear difference of innovation seen in TETRA handsets
The difference in handset prices is outstanding
Conclusions
Cellular networks cannot serve the needs of mission critical radio users – dedicated radio network is needed
TETRA standard provides:- Widest set of functionality- High capacity at low cost- Fast development of innovative product solutions- True multi-vendor market and genuine
competition
