SDR-H2

HANDHELD MANET MESH TRANSCEIVER / SOFTWARE DEFINED RADIO

Handheld SDR radio built for military mesh networks: a 2 watt software defined radio in a rugged soldier-radio form factor that holds voice, video, and tactical data where the network has to move with the operator.

Book a Demo

Built on DTC's field-proven SDR-C core, the SDR-H2 packs a full software defined radio into a 634 gram handheld unit. The same architecture that runs across DTC's airborne and vehicle, in the operator's hand, so a single platform meshes the dismounted soldier with every other node in the network. MeshUltra-X, the waveform behind that network, manages channels and encryption over the air and scales automatically as teams join or drop. Because the radio is defined in software, new capabilities arrive as a download rather than a hardware change. Software defined audio drives a wide range of off-the-shelf tactical headsets and peripherals from the same unit, so operators keep the equipment they already trust.

In a meshed network, the SDR-H2 carries up to 16 voice talk groups in full-duplex VOX while streaming IP, HD video, and Cursor on Target situational awareness to the command picture. Ground operators mesh automatically with UAVs, unmanned ground vehicles, maritime assets, and fixed infrastructure nodes, because every radio runs the same MeshUltra-X core. Cursor on Target output feeds straight into Battle Management Systems, so the position and video an operator generates reaches the people who act on it. Three dedicated input and output ports, in different rugged formats, let the same unit serve as an airborne, UGV, or infrastructure node as readily as a handheld radio.

Sealed to IP68 and rated from -20 °C to +60 °C, the SDR-H2 is designed to meet MIL-STD-810G for shock, vibration, and environmental stress. DTC's Interference Avoidance System and operation in bandwidths down to 1.25 MHz hold the link together in congested and contested spectrum, where fixed-channel radios fail. Built around the SDR-C core, already proven across DTC's mesh and point-to-point COFDM radios, the SDR-H2 brings that field record into a soldier-radio form factor. Designed for extreme conditions, the SDR-H2 holds the network in conditions that other radios fail under.

MISSION OUTCOME

The SDR-H2 delivers handheld mesh communications for military and unmanned operations, meshing voice, HD video, and tactical data across ground, air, and sea from a single 634 gram unit. For teams that need a software defined radio handheld node and a network that reconfigures itself under pressure, the SDR-H2 holds the link where infrastructure ends and the mission continues.
