Does TETRA1 handle data?

• Database look up• AVL• Email• File transfer• Limited slow

scan video• But some multimedia

applications could ask for more….

TWC2005 – November 2005November 05 - TETRA World Congress 2005

Mission Critical Data Applications on TETRA• Today’s applications need data capacity

– Frequent messages, small payload:• AVLS from portables and vehicles• Database access• Status messaging

• But some applications starting to need more data throughput– Less frequent messages, much bigger payloads

• Mug shots• File transfer• Slow scan video

TETRA 2Updated plans can be downloaded as appliance is en route

Fire fighters get latest informationFire fighters get latest information

Check database of hazardous chemicalsTETRA 1Text based results from database search

TETRA 2Text and image results from database search

Fire fighters get clearer informationFire fighters get clearer information

TETRA2 brings new capabilities … to AmbulanceTransmit an ECG trace from ambulance to doctor in hospitalTETRA 1Transmit compressed ECG

TETRA 2Less compression used means more details on ECG

More accurate diagnostic for heart conditionsMore accurate diagnostic for heart conditions

Transmit pictures from scene so doctors can predict injuryTETRA 1still images or slow scan video

TETRA 2More detailed video image

Doctors can make more accurate predictionsDoctors can make more accurate predictions

TEDS (TETRA Enhanced Data Services)

– High Speed Packet Data for TETRA

TWC2005 – November 2005November 05 - TETRA World Congress 2005

TETRA Enhanced Data Service - TEDS

• Backward compatible with TETRA Release 1– Network integration capability

• Flexible data rates and spectrum use– 25, 50, 100 and 150 kHz channels bandwidths– Can trade off data rate, spectrum and range

• Integrated TETRA 1 and TEDS system– i.e. can receive TETRA 1 calls on TEDS channels

• Technology selected for TEDS use – Multi-carrier QAM (Quadrature Amplitude Modulation) in all bands– D8PSK in 25 kHz

High speed packet data service for TETRA enabling faster data rate and higher data capacity

TWC2005 – November 2005November 05 - TETRA World Congress 2005

High Speed Packet Data Deployment

• TEDS will be the solution for mission critical• A range of channel bandwidths available in

the standard– Offer a single TEDS channel at each site, in addition

to TETRA 1 voice channels– Provision channel bandwidth based on number of

users and their data application requirements

• The modulation scheme can adapt to radio transmission conditions

GPRS versus TETRA - Availability

GPRS constraints TETRA 2 benefits

Availability

At times of high voice load there is little or no GPRS service available

– Revenue streams and profit targets dictate data coverage and capacity

– GSM cells often provisioned with dynamic GPRS channels to give priority to lucrative voice services

Users get the level of data service they need

– End user requirements dictate the coverage and capacity in their own private network

– TETRA cells are provisioned with the data capacity to meet

end user’s operational needs

TWC2005 – November 2005November 05 - TETRA World Congress 2005

GPRS versus TETRA - Predictability

GPRS constraints TETRA 2 benefits

PredictabilityGPRS users often see lower throughputs than today’s TETRA packet data users

– GPRS Data bandwidth is shared between many public users

TETRA users get access to the high bandwidths offered by the standard

– TETRA data bandwidth is shared only with users on a private network

TWC2005 – November 2005November 05 - TETRA World Congress 2005

GPRS versus TETRA - Security

GPRS constraints TETRA 2 benefits

SecurityMeets commercial security requirements

Meets Government security requirements, e.g.

–Mutual authentication–Longer keylengths means much harder to decrypt

TETRA: Availability – Predictability - Security

TWC2005 – November 2005November 05 - TETRA World Congress 2005

Typical upgrade to TETRA2

Requirements from all users….

• Maintain GoS (Grade of Service) for voice and any legacy data services

• Increase capacity for new data services

• Easy upgrade

Your expectations for TETRA2

TWC2005 – November 2005November 05 - TETRA World Congress 2005

Things to Remember

• New Spectrum– Maintain present spectrum to keep GoS for

existing voice & data services

• New Terminals for TEDS services– Retain present terminals for existing voice &

data services

In partnership for TETRA2

TWC2005 – November 2005November 05 - TETRA World Congress 2005

Spectrum: Progress has been made…..• ECC (Electronic Communications Committee) has just approved a

Work Item to add support for Wideband technologies in 385MHz – 470 MHz

– 385 MHz – 390 MHz385 MHz – 390 MHz would be the ideal choice for TETRA 2

– reserved for Nato– Sporadically used at present– users need to be very influential

• National regulators are responsible for allocating spectrum – Will Consider the local operating environment– Will Balance requirements from public safety, transportation, etc.

Users need to exert their influence through the MOU and directly to their National regulators

TWC2005 – November 2005November 05 - TETRA World Congress 2005

TETRA 2 takes the lead

The facts of life: • If you already have TETRA you will still be

able to use existing:– Terminals– Application– Services

• When you get TETRA 2 you gain:– Data speed & capacity– New multi media applications– Increased operational efficiency– New possibility to innovate
