TETRA data services: Applications & innovations Risto Toikkanen Vice chairman, TETRA Association Wireless China, Beijing 2007 13.7.2007 1
Agenda: Usage trends How the standard supports development TETRA data applications by categories, examples Middleware and SW platforms as market enablers A look into future data possibilities Slide 2
Trends in user needs Field control DATA Situation overview DATA Information value chain DATA Information overflow control DATA Secure reliable group communication is the foundation Surveillance DATA Always connected COVERAGE Total Cost of Ownership OPEX Process automation DATA Slide 3
Why TETRA standards boost applications Efficient SDS/status for radio resource optimisation Among the first to integrate IP packet data when IP became dominant in the computer world PEI standard for open data terminal connectivity LIP (Location Information Protocol) for multi-vendor GPS positioning TETRA Rel 2 TEDS high speed data for totally new performance level And certified TETRA Interoperability helps the market grow faster Slide 4
Evolution of TETRA data capacity Status messaging Short Data Service (SDS) Automatic Vehicle Location (AVL) Telemetry Compressed video Reporting Telemedicine Compressed images Database queries WAP browsing of databases WAP push alerts to field units Location applications Video streaming High-resolution images Real-time command & control Integrated monitoring/control Documentation library Identity management Field command with improved situational awareness TETRA short data services TETRA multi-slot packet data TETRA one-slot packet data TETRA Rel 2 TEDS Slide 5
Main categories of data applications 1. Command & Control Massive integrated systems running multiple databases and applications 2. Geo-location, positioning Many organisations use GPS for various purposes 3. Video and imaging Situation picture and continuous surveillance 4. Messaging Text, data, voice, multimedia / one-to-one and one-tomany Examples follow Slide 6
Integrated Command & Control System Recording Supporting functions Database access Location based services Call Taking Dispatchin g Radio Comms Field Work Reporting Slide 7
Railways train control TETRA chosen by 45 rail customers from Brazil to China The SNCF in France made a multi-vendor TETRA train speed trial at 570 km/h it works Slide 8
Automatic Vehicle/Person Location Built-in GPS TETRA LIP AVL / APL Applications Every application does not need to poll the users Centralized Location Server: To maintain location data To distribute to all applications Slide 9
AVL Automatic Vehicle Location Example images from transport industry application Truck with -Truck number -Radio number -Speed -Date -Time -Length of blue arrow is proportional to speed 3 Trucks on a parking area beside the motorway They are not moving thus the symbol is a point, not an arrow Slide 10
Automatic number plate recognition Video camera monitors road traffic or special entry points (borders, car parks) Software picks up vehicle license plates in real time from the video stream, convert license plate to text and compares string against databases Automated alerting to field units Slide 11
Multi-format message retrieval Delivery as: - Text msg - Email - Synthes d voice - GSM SMS - Via: - Radio - Internet - Desk phone - Cellphone Slide 12
Bilbao Bus text to speech conversion Slide 13
Data support in multi-vendor environment Standard interfaces, PEI for data terminals Standard protocols, LIP for positioning Common SW platforms and middleware Generic terminals, no radio programming WAP & web browsers Java TM clients Successful applications should work over multi-vendor radios and data devices even over multiple network technologies Slide 14
Police workflow for Missing Person case At missing person s home Police scans the latest photograph of the person Police sends image over TETRA IP to Dispatcher s application At the police station Dispatcher publishes the image and form in XHTML pages (e.g. police intranet) Dispatcher sends alert to field units as WAP PUSH Field units selection can be e.g. location based This takes only one minute! In the field Officers receive data message that opens the link to content Officers get true color photo on the display Slide 15
Downloadable applications - Java Java client in TETRA radio Remotely managed Download to those who need it Can run also off-line E2EE encryption Slide 16
What will high speed data bring TETRA Enhanced Data Service (TEDS) standard More efficient multi-carrier modulation Automatic adaptation of modulation and coding Wider radio channels 25/50/100/150 khz Ten times higher data rate by 50 khz channel alone Backward compatible with current TETRA Release 1 Wide area & wideband Slide 17
TETRA Rel 1 & Rel 2 data transfer rates 250 200 Gross bit-rate Net bit-rate TETRA Data Speed ~700 kb/s The TEDS net bit rates (throughput) on the left are conservative (coding rate = ½) kb/s 150 100 50 Net bit rate can be doubled to e.g. 160 kbit at 50 khz with coding rate = 1 0 Demo in TWC2007 TETRA SSPD TETRA MSPD TEDS 4QAM/25k TEDS 64QAM/50k TEDS 64QAM/150k TEDS enables new types of applications Slide 18
First applications on TEDS? TETRA Association TEDS workshop 2007: Mobile command centre Video up- & downlink Multimedia messaging, maps, drawings, images Remote maintenance of terminal devices and there will certainly be many more Plus, to provide radio capacity to 10 or 20 or times more users of the earlier applications Slide 19
