TETRA/TEDS Base Station Protocol Stack

Etherstack has a comprehensive range of TIP/ETSI TETRA compliant Base Station and Core Network options.

Our standard Base Station product is available with a single site trunking application and multiple site support, and features Trunked Mode Voice+Data (TMO V+D), all call types and supplementary services, all registration and migration mechanisms, and address management. A management interface - including configuration, alarm and monitoring functions - is also available.

The software is constructed as a set of layered components for a clean, adaptable architecture. These components can be supplied individually or together, and can be split across multiple processors if necessary; for example, the upper layers and application can run on a Base Station processor while the lower layers reside on the Base Station transceivers.


Full TIP/ETSI TETRA compliant Trunked Mode Voice+Data (TMO V+D) / Single Site Support / Multi-Site Support / Sophisticated Management Interface / Registration and Migration mechanisms / Comprehensive Address Management / All TETRA Voice Call types / All TETRA Supplementary Services / Short Data Service (SDS) Support (Types 1 through 4) / SNDCP Packet Data / Single-Slot Packet Data (SSPD) / Multi-Slot Packet Data (MSPD) (Optional) / End-To-End Encryption / Air Interface Encryption (Classes 1, 2 and 3) and Key Management / Group and wide area calls / PABX, PSTN and dispatcher calls / Advanced link MS-BS communication & FCS support / Energy saving modes and closed-loop power control

TEDS Protocol Stack

Etherstack has supplemented its field-proven TETRA Release 1 protocol stack with 25kHz - 150kHz TETRA Enhanced Data Service (TEDS).

TEDS is a spectrally efficient integrated high speed data service that is scalable to wideband and ultimately broadband rates.

Our TEDS solution gives you an advantage. Etherstack has invested significant effort to overcome the technical challenges of high rate data extension. We have implemented advanced link adaptation, turbo coding and Quality of Service (QoS) algorithms that ensure the best possible performance outcome.

We have also implemented a complexity reduction exercise so that our TEDS solution can be deployed on existing TETRA hardware in 50kHz QAM (4 to 64) mode. CML Microcircuits has published the results of this in a white paper.

TETRA and TEDS protocols are available either separately or integrated together and are compatible with a wide variety of hardware and software environments.

Risk-Free 12 Month Warranty

After delivery, Etherstack provides a 12-month warranty against any defects. If an issue is found we fix it immediately at no extra cost. We actively maintain stack source code, incorporating bug fixes for our customers as well as tracking changes to the standards. After the warranty period is over, we offer an annual maintenance subscription for access to ongoing code releases and issue resolution.

Full Test and Debug Capability

Our TETRA/TEDS BS Protocol Stack supports fully automated testing and is supplied with Etherstack's automated test environment ELITE, Etherstack TraceViewer and a comprehensive library of test scripts that provide traceability against all protocol stack requirements.

These tools allow you to maintain the software across different radio platforms and allow advanced debugging during development, integration, field trials and as new features are introduced over time.

Protocol software represents a key investment. It is essential you can reuse it to save money, reduce risk, speed time-to-market and respond to changing markets.
