Summary

• Where TETRA may serve Defence market

• How TETRA meets some Defence market needs

Missions• Sites protection : air bases, camps, dockyards• Border surveillance• Peace keeping• Combat training • Military Police• Special operations• Fire brigades• Nationals protection • Logistics• …

Defence market trends• Use of civilian technology : « tactical

internet »• Use of civilian products (COTS) … or

derivated from …• Multinational operations – joint forces

more interoperability more mobility

• More data from field to Command Center• Focus on pure Defence missions

no need for Telecoms & IT experts Simplified or even externalised

maintenance

• … but still top level security and reliability

Technology place

TETRA meets Defence traffic density needs (TDMA)

TETRA offers Voice and Data TETRA offers coverage solutions adapted to

each operational situation (TMO / DMO) TETRA offers gateways with Voice and Data

applications of the Command Chain TETRA offers a wide range of compatible

terminals to meet any operational condition TETRA offers long-term technology and

products availability TETRA offers high-grade security with

localisation options

Services place

• Group call, the basic use,

• Duplex, call forwarding, PABX access … for general officers,

• Data transmission : sensors, combat training …

• SDS for AVL

Mission critical requirements

• Mobility

• Quality of service

• Security

• Low bandwidth compatible

• Easy O&M

• Reliability

Mobility : progression in service

• Nothing but hand-portables : Direct Mode Operation• Base station not in place : DMO repeater• LOS not in place : Stand-alone base station • Backbone not 100% available : peer-to-peer base stations• Finally : a wide area radio network featuring roaming and

handover

Quality of service

• TETRA offers Voice & Data on a single carrier

• Time critical communications protected from congestion by priority management

• Pre-emption is available when necessary

Security

TETRA offers essential security mechanisms

• Authentication : infrastructure against fraudulent mobile,

• Authentication : mobile against fraudulent infra.

• Encryption on radio segment : AIE• End-to-end encryption• On the Air Re-keying

Low bandwidth compatible

• Deployable LOS offer low bandwidth

• Even worst for Satcoms

• TETRA is low bandwidth-consuming : typically 3 first Erlang @ 64kbps

Easy Operation & Maintenance

• Intuitive MMI

• Adaptation to frequently moving field situations

• Performing fault detection to improve availability

Reliability

• Deployable may cause … unsteadiness

• Tactical TETRA must offer back-up solutions at any level

• Products must resist to severe operational conditions : vibrations, shocks, rain, dust …

• Much more than civilian networks, tactical net. must be resilient to backbone quality degradation

A wide choice in products

• TETRA is a multi-vendor solution,

• A wide diversity in products, Mil. Spec. compliant– Ruggedised portables,– Covert portables,– Shock Mounted Racks base stations

& infra.,– Outdoor base stations,– …

What about IP ?

• TETRA over IP is a mature technology,

• Mil. Com experts speak about Tactical IP,

• … welcome T2oIP for Tactical TETRA over IP
