TETRA Services & Facilities Risto Toikkanen Vice chairman, TETRA Association TETRA Experience, Warsaw June

Contents The package vs user needs Basic PMR voice services Basic mobile telephony Advanced group voice Advanced mobile telephony A quick look at data Other interesting facilities Making the difference Shared networks Conclusions Data services and security are discussed in other presentations

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

Unique Powerful Package Four in One: –Group voice & dispatch –Mobile telephony –Messaging –IP data Uncompromised security Capacity for nationwide shared networks TETRA standard Release 2 will strengthen the package with High Speed Data + few other functions OPEN HERE

Basic PMR Voice Services (and more) Excellent voice quality of ACELP codec Group calls –Wide area groups up to nationwide –Fast call set-up –Virtually unlimited number of talkgroups –Economic use of resources Individual call (semi-duplex) –Direct call i.e. press and talk –Hook call i.e. answer when it rings Mobility management and fast cell reselection

Basic Mobile Telephony Individual call (full duplex) –Radio to radio –PSTN/PABX/ISDN connectivity Mobility management and fast cell reselection Before TETRA this was not self-evident

Advanced PMR Voice Services Pre-emptive Priority Call (PPC, emergency call) Call queuing when resources busy Priority Call up to 16 priority levels (PC & PPC) Late Entry (LE) Ambience Listening (AL) Call Authorised by Dispatcher (CAD) Discreet Listening (DL, monitoring of calls) Dynamic Group Number Assignment (DGNA) Talking Party Identification (TPI)

Advanced Mobile Telephony Services MS-ISDN numbering to address the whole world Short numbering schemes Modern PABX facilities such as –Calling party identification –Barring of calls (incoming & outgoing) –Call forwarding –Call Waiting Billing and Customer Care systems/interfaces Text messaging

Data Communication Services Status service –efficient, real time –group and individual addresses Short Data Service, SDS –text messaging –GPS position data –group and individual addresses IP packet data file and image transfers database access reporting WAP, web browsing Circuit switched data High speed data: TETRA Enhanced Data Service TEDS comes in Release 2

End-to-end applications for end-user needs TETRA has created new type of application supply Manufacturers’ development partnership programmes gather even hundreds of software houses A. Horizontal applications common with commercial mobile data business –Positioning, databases, etc high volume applications B. Very specialised fit-to-purpose segment specific applications –Command & control, telemedicine, telemetry, …

Other Services & Facilities Transmitter Inhibit Direct Mode operation (DMO) –Traditional –Gateway –Repeater Air-Ground-Air (was part of Release 2) Location Information Protocol (LIP) (was part of Release 2) Fall-back operation of Base Stations Network Interfaces for Telephony, Data, Internet,… Command & Control Systems, Network Management, etc. Full security (discussed elsewhere)

Versus Cellular Fast response group calls Mission critical dispatching Availability for mission critical –Daily use –Under emergencies –Capacity of semi-duplex –DMO, BS fall-back Full security –(mutual) authentication –Air & end-to-end encrypt –Disabling of radios Features: PPC, LE, Al, DGNA Versus other PMR Full duplex Cell handovers TDMA capacity Spectrum efficiency Voice + data truly in use Multi-vendor market Cost benefits Fast innovations –Compare the handsets for GPS, color display, WEB, WAP, JAVA, … Key differentiators of TETRA vs others

Sharing a network Now common practice with TETRA in Public Safety –Requires VPN and controlled privacy –Services and parameters per user organisation –Fleet & service management per user organisation Leads to big savings in CAPEX & OPEX Leads to nationwide high-capacity networks –TETRA has shown that it can perform
