- Group & One-to-One Calls: Efficient team coordination with dynamic call grouping.
- Fast Call Setup (<300ms): Instant voice transmission when response time is critical.
- Direct Mode Operation (DMO): Communicate radio-to-radio even outside network coverage.
- Scalable for Large Fleets: Ideal for single sites or multi-region coverage.
- Rugged, Professional Hardware: Devices built to military-grade durability standards.
TETRA Frequently Asked Questions...
What is TETRA?
TETRA (Terrestrial Trunked Radio) is a professional mobile radio and two way communication standard used globally in critical sectors like emergency services, transportation, and utilities. It provides secure, encrypted, and reliable voice and data communication, enabling users to operate over private networks or via direct radio-to-radio contact.
Developed by the European Telecommunications Standards Institute (ETSI), TETRA supports advanced features such as:
Instant push-to-talk voice
Group calls and individual private calls
Short data service (SDS)
Emergency alerts and priority override
High call clarity in noisy environments
Who uses TETRA Radios
TETRA radios are trusted by industries where reliability, privacy, and fast communication are critical. Common sectors include:
Emergency Services: Police, fire, ambulance
Transport & Airports: Ground staff, operations, logistics
Utilities & Infrastructure: Power plants, oil and gas, water treatment
Healthcare: Hospitals and private emergency contractors
Events & Security: Stadiums, festivals, and crowd control
Its resilience in mission-critical environments makes TETRA the top choice for government agencies and essential service providers worldwide.
What Are the Benefits of TETRA vs Other Systems?
TETRA systems outperform traditional analogue and basic digital (e.g. DMR) radios when it comes to scalability, encryption, and speed.
Secure & Encrypted: AES encryption to protect sensitive communications
Fast Call Setup: Voice calls connect in under 300ms
Group Calling: Instantly connect teams with dynamic call groups
Direct & Network Modes: Stay in contact with or without infrastructure
Built for Harsh Environments: Rugged hardware, long battery life, crystal-clear audio
TETRA also supports data services like GPS tracking, SDS messaging, and remote radio programming.
What Is Direct Mode Operation (DMO)?
Direct Mode Operation (DMO) allows TETRA radios to communicate directly with each other, without needing any network infrastructure like repeaters or base stations.
This is especially useful in:
Remote areas with no coverage
Disaster zones or emergency sites
Building interiors or tunnels
Some TETRA devices also support DMO repeater mode, where one radio acts as a bridge to extend range even further.
Is a Licence Required for TETRA?
Yes. TETRA radios operate on licensed frequencies and are typically set up through a dedicated network infrastructure or through a third party provider. Most government agencies and large companies operate their own TETRA networks.
However, there are also managed TETRA services where you can rent access to infrastructure, making it accessible without needing to build your own system.
