AgendaAgenda
• TETRA and public cellular systems• Comparison with other PMR technologies• TETRA market• State-of-the-art technology• The future
Frequently Asked QuestionsFrequently Asked Questions
• Why do I need TETRA instead of public cellular networks (GSM, GSM-R, UMTS)?

TETRA is a real open standardTETRA is a real open standard
• TErrestrial Trunked RAdio (TETRA) is an open standard which is defined by the ETSI to meet the needs of the most demanding professional mobile radio users.
•It has been fully accepted by all the European and many other Administrations.
•ETSI has started the work program for TETRA release 2
Interoperability certificationInteroperability certification
• The Interoperability Certificate (IOP) assures that various manufacturers infrastructure and terminals can indistinctly operate on any TETRA network
•The various functionality tested and approved are summarized in public tables
•Tests are executed by an independent accredited test house: up to now Teledanmark (Danish operator)
TETRA and APCO 25TETRA and APCO 25
• Project 25 is a Digital Radio Project that involves both APCO and TIA members, in ANSI/TIA Standardisation
• Project 25 •Phase 1 is 12.5kHz FDMA•Phase 2 has FDMA (6.25 kHz) and TDMA (12.5 and 25 kHz) components
• TETRA has been selected early in 2000 as TDMA option for the phase 2 (IMBE codec and DES encryption)
• APCO 25 and TETRA are the only two digital standards for PMR originated from international standardisation institutes that are being deployed across the world

Customer trendsCustomer trends
•Public safety and security services •EUROPE: TETRA is the consolidated open standard technology for PSS radio mobile systems. Almost all European Countries are using (or have plans to use) TETRA
•WORLD WIDE: interest is consistently increasing and first projects are starting in all regions
•Transport and utilities (Civil Users)•Projects in this segment partially suffered the spectrum issues for civil TETRA in the past but the solution to these problems is on the way
TETRA growth outside Europe: ChinaTETRA growth outside Europe: China
• On April 2001 TETRA has been adopted as national standard by Chinese administration. Most of the allocated radio channels are in the 800MHz frequency band
• First tenders for TETRA have already been issued and assigned for transport (railways and subway companies) and public safety applications
• TETRA market growth is envisaged for a long duration in China
TETRA growth outside Europe: USATETRA growth outside Europe: USA•TETRA adopted as basis of a 4-slot TDMA system for Project 25 Phase II
•MOU proposal includes use of DVSI IMBE codec, DES encryption and Phase I FDMA interoperability
•TR-8 formulating committee (TR-8.14) established to develop ANSI/TIA standard
• TR-8.14 is working on two variants:•Standard for Public Safety with changes•Standard for Non Public Safety without changes to codec or encryption
• Shell Standards in draft form, with ongoing work, to complete during 2001
• North American TETRA Forum set up, providing support from users
