Basic Requirements of any TETRA Network/Terminal
A radio is not just for Voice communications it is a key operational tool that helps save lives.
The key requirements of a TETRA radio terminal are:•Best and most reliable voice communications•Best and most reliable data communications
Extended Coverage For Voice and Data
TMO Repeaters • On frequency repeaters that extend TMO coverage only
• Can be expensive and normally are fixed to a location – inflexible
DMO Gateways• Provide a link between TMO users and DMO users who may not have enough
RF power to reach the network
DMO Repeaters• Extend coverage between DMO users
Some terminals can act as both Gateways and Repeaters
No TMO Network Coverage
What is a Gateway?

TMO
A Gateway connects users operating in Direct Mode with the Trunked Mode network
No TMO Network
Coverage
Users out of network coverage can report their current position to either their vehicle or to an operator via TMO and to their vehicle Gateway
Alarm indications can report the position of the originator

What is a Repeater?
A Repeater extends coverage between DMO usersTypically a vehicle mobile strategically placed acts as a DMO Repeater to extend communications within a closed group.

Users of Gateways & Repeaters
Utility companies
Fire Services

Public and Private Ambulance Services
Police Services
Airports
Border Guards
Many users now buy Gateway and Repeater hardware enabled radios and add the functionality when needed.

Hazardous Areas
Area with possible presence of a potentially explosive atmosphere
An explosive atmosphere is defined as a mixture of:
– flammable substances (gases, vapours, liquids, mists or dusts)
– with air
– under atmospheric conditions
– in which, after ignition, the combustion spreads to the entire unburned mixture
Definition of Hazardous Areas
An atmosphere, which could become explosive due tolocal and/or operational conditions, is called :
a potentially explosive atmosphere.
Directive 94/9/EC (ATEX Directive)
• The European Directive 94/9/EC (ATEX Directive)
– It covers all equipment and protection systems to be used in potentially explosive atmospheres.
– This is an increase in scope compared to previous national regulations.
• Typical Applications
– Fire Brigades
– Petrochemical Plants
– Fixed offshore platforms
– Ports and Airports
– Industries (chemical, pharmaceutical, ...)
– Mines

Part 2 ‐ Product ComplianceTETRA Interoperability (IOP)
• IOP ensures that TETRA equipment from one manufacturer functions (interoperates) with TETRA equipment from another manufacturer.

• Manages Interoperability Process
• Creates TIPs (TETRA Interoperability Profiles) and Test Plans
Any Member of the Association is welcome to join
Technical Forum (TF)
Operator and UsersAssociation - OUA
• Creates usage scenarios for features
• Sets IOP TETRA feature priorities
Not open to manufacturers
Do I need Interoperability?
• One Supplier– makes life easier for operator & user– the supplier ensures that infrastructure & terminals operate together?
– No one supplier provides every type of terminal– Dependent on one supplier’s development timescales– Features not always released on infrastructure & terminals at same time
– Locked in – watch the price of enhancements
When you buy your cell phone – do you ask who supplied the network?
Benefits of an openmulti-vendor market
• User benefits– wide choice of compatible terminals – 10+ suppliers– specialised products for special needs– continuous and fast product development & innovation– genuine competition, hence lower prices (c.f. P25)– reduced dependency on a single supplier
• Industry benefits– larger market, greater volumes– increased possibility to invest – faster product creation– Market longevity
The TETRA Association created the IOP certification process to guarantee an open multi-vendor market
