DTC at DSEI 2025: Delivering Sovereign Tactical Communications for the Multi-Domain Battlefield
Mission-critical capability. Seamless integration. Operational dominance
As the demands of modern warfare evolve, Domo Tactical Communications (DTC) continues to lead with a communications ecosystem designed to dominate the multi-domain battlespace. At DSEI 2025, DTC will highlight how its platform-independent, waveform systems deliver sovereign control, modular adaptability and proven performance across all domains — land, sea, air and cyberspace.
Whether enabling dismounted soldiers, integrating with unmanned platforms, or maintaining long-range comms in disconnected environments, DTC's technology supports:
- Waveform Agnostic & Platform Independent operations — providing users the freedom to deploy across soldier, UxV, and mounted systems with the waveform of their choice.
- Sovereign Control — including in-country crypto integration, spectrum management, and independence from vendor lock-in.
- Battle-Proven Versatility — built for real-world deployments, from soldier patrols to vehicle convoys and autonomous missions.
- Modular & Scalable — designs that adapt to mission parameters, environmental demands, and national defence policies.
We sat down with DTC experts to explore some of the key advancements they will be showcasing this September.
Q: What's new about DTC's approach to soldier communications, and how does the Sentry Mesh 6161 fit into future soldier systems?
A: At the heart of DTC's soldier-focused innovation is the Sentry Mesh 6161 — a personal software-defined radio (SDR) engineered to provide robust communications in the most contested environments. This lightweight 410g radio delivers up to 87 Mbps throughput, 2x2 MIMO architecture, 2W transmit power, and full support for 32 simultaneous talkgroups per channel.
Recent updates to the Sentry 6161 include support for the expanded S-Band frequency range of 1.7-2.7 GHz — enhancing operational flexibility and enabling better spectrum access in complex RF environments. Additionally, a new MBITR battery attachment (coming soon) will allow users to power the radio using legacy MBITR-compatible gear, streamlining integration into existing soldier kits.
It's built to integrate seamlessly with End User Devices (EUDs) through options like the Kägwerks DOCKUltra™, enabling soldier-worn AI, real-time PLI, and intuitive control through MeshUI™. DTC is combining ruggedised hardware with flexible software to create a tactical edge — increasing lethality and survivability for dismounted forces operating in peer-to-peer threat environments.
Q: With the growing importance of unmanned platforms, how is DTC enabling seamless integration between UxVs and soldiers on the ground?
A: Unmanned systems are now a critical extension of the tactical edge. DTC's BluSDR™ family of mesh radios provides high-throughput, low-latency datalinks across UAVs, UGVs, and USVs. These systems deliver secure video, voice, and data in real time, even under heavy jamming and interference.
DTC's modular integration approach mirrors soldier-worn systems — allowing shared waveform use, intuitive management, and seamless relay functionality between manned and unmanned assets. This convergence enables warfighters to maintain command and control while extending operational reach, enhancing survivability, and reducing operator exposure.
Q: What is the significance of multi-waveform capability, and how does it change the future of tactical communications?
A: DTC is introducing the first multi-waveform soldier radio portfolio — a transformational step in modern battlefield communications. This capability enables seamless switching between proprietary and third-party waveforms, ensuring interoperability with coalition partners, UxVs, and legacy systems without vendor lock-in.
It allows dismounted radios to adapt at the waveform level — decoupling them from fixed vehicle systems and enabling more cost-effective upgrades. This preserves investment in existing mounted infrastructure while futureproofing dismounted capabilities. The result is better ROI, improved survivability through waveform agility, and mission-tailored adaptability across the tactical ecosystem.
With support for 3rd-party waveforms such as TSM alongside proprietary MeshUltra™, DTC's radios empower users to pick the right waveform for the mission — ensuring continuous connectivity and unmatched operational flexibility in contested and coalition environments.
Q: How is DTC helping armed forces achieve true sovereign control over their communications systems?
A: Sovereignty is central to DTC's offering. All systems are waveform-agnostic, designed to operate across multiple platforms with user-defined crypto and frequency control. Nations can build and maintain their own waveforms, manage spectrum allocation, and avoid vendor lock-in.
Whether through the cognitive radio capabilities embedded in DTC's latest software releases, or the ability to integrate and control systems through national infrastructure, DTC ensures armed forces can stay interoperable without compromising independence or security — delivering decisive capability on their own terms.
Q: What is SprinTAK, and how does it enhance long-range communications for forces operating in disconnected environments?
A: SprinTAK is a breakthrough innovation that bridges DTC's MANET mesh and HF radio ecosystems, ensuring persistent situational awareness even when SATCOM is degraded or unavailable. Originally developed for U.S. SFAB training, it allows TAK data to be collected and transmitted via HF back to command nodes.
This capability is critical for forward units, special operations forces, and multinational deployments where infrastructure is limited or denied. Combined with DTC's lightweight Sentry-H radios, SprinTAK provides an essential BLOS layer in the P.A.C.E. communications plan, supporting voice, text, and location data in the most challenging environments.
DTC's full-spectrum solutions — spanning soldier, unmanned, vehicle, and command echelons — will be on display at Stand S13-530 in the DSEI 2025 Technology Zone. From advanced SDRs to sovereign network architectures, DTC is ready to demonstrate how its technologies provide agility, resilience, and control in multi-domain operations.
