15. TETRA 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

16. Interoperability 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)

17. TETRA 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

24. Public safety and security services
Customer 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

25. TETRA 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

26. TETRA 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
