Objectives behind TETRA Standard

• Define a digital Professional Mobile Radio (PMR)
  standard to satisfy the current and future needs
  of especially Public Safety and other PMR users
  across Europe
• Unite fragmented PMR markets into one common
  market harmonized use of spectrum
• Fulfill European authority co-operation
  requirements (Schengen Treaty) to enable European
  Integration cross-border operation using common
  frequency spectrum

• Users
• desired features
• choice
• competition

• Radio regulators
• spectral efficiency
• harmonization

• Manufacturers
• open market volumes
• to ensure open standards, the ETSI IPR policy
  stipulates patented solutions to be made
  available at fair and reasonable terms

• Operators

TETRA market today

• Number of TETRA contracts in July 2004
• 505 contracts (325 contracts by September 2003)
• Europe 357
• APAC 53
• Africa 18
• Latin America 24
• Middle East 26
• Very positive user experiences from networks that
  are in operation
• TETRA has improved the security and safety of
  field units
• Shared multi-agency operations have been
  effective during incidents
• Open standard has affected product pricing,
  resulting in very competitive prices compared to
  single vendor solutions

TETRA Service classification

• TETRA is not only a radio access standard, it is
  also a standard defining the services and
  functionality

• Nearly 30 supplementary services
• priorities, late entry, DGNA,
• - fleet services
• - telephony supplementary services

Bearer services data transport - packet,
circuit, single/multi-slot
Teleservices voice calls - one-to-one, group,
broadcast

Nature of TETRA Standard

• The TETRA standard by ETSI
• Provides
• Rich variety of tools and mechanisms to meet user
  requirements
• Multiple possibilities to implement end-user
  services
• ? Need to agree a common implementation to
  achieve interoperability
• TETRA interoperability certification ensures open
  multivendor market.

11
What does interoperability mean?

• Radio terminals and network infrastructures from
  different manufacturers work together

Interoperability between products and features

Interoperability (IOP) - Advantages

• For user
• Manufacturer independent supply and 2nd source
  guarantee
• Benefits of competition
• Wider selection of products (gateway, special
  terminals etc.)
• Lower prices
• Constant improvements
• Increased speed of innovation

• For manufacturer
• Larger (global) market
• Critical mass for special products
• Potential to focus to own strengths
• Increased investment opportunity
• Faster time to market
• One common and independent specification
• No vendor bias

13
What makes TETRA unique

• Fast call set-up time
• Excellent voice quality, elimination background
  noise
• Direct Mode (DMO)

Future with TETRA

• TETRA standard is being developed to support
  higher data rates
• TETRA Release 2 will support TEDS (TETRA Enhanced
  Data Service)
• User Requirements Specification for TEDS
  developed based on query among ETSI members, main
  input from Public Safety Users
• Release 2/TEDS standard expected to be completed
  2005
• User data rates up to 100 kbit/s databases,
  graphics, images, ...
• Radio channels 25, 50, 100 kHz, multi-carrier
  modulation
• Backward compatibility with TETRA Release 1
  control channel for easier upgrades of networks

TETRA Release 2 will maintain the competitiveness
of TETRA for the years to come
