StreamCaster MINI 5200 (SM5200) tactical MANET radio

The StreamCaster MINI 5200 (SM5200) is a compact tactical MANET radio for line-of-sight mesh data links, made by Silvus Technologies. It carries voice, video and IP data over a self-forming, adaptive mesh network without fixed infrastructure. Silvus describes it as its smallest fully featured MANET radio, built for ground forces that need a mobile, low-profile link that works standalone or together with the StreamCaster NEXUS tactical networking system.

The radio runs the proprietary Mobile Networked MIMO (MN-MIMO) waveform with COFDM modulation. Auto link adaptation keeps throughput optimized as conditions change, and the waveform is built for multipath and non-line-of-sight performance and for mobility on high-speed platforms. MIMO techniques include spatial multiplexing for throughput, space-time coding for robustness, and transmit and receive beamforming. The mesh is self-healing and self-forming, uses single-frequency time division duplexing, and supports all common topologies.

For link planning, the key figures are these. The radio delivers up to 100 Mbps of adaptive data rate and an average latency of 7 ms at 20 MHz channel bandwidth. Native transmit power is user adjustable up to 2 W, and transmit beamforming raises the effective power for more range and throughput. A single network scales to more than 550 nodes. Power consumption is 4–13 W at 2 W transmit power, which sizes the load on the host battery or vehicle supply. The radio operates in L, S and C bands with single and dual band options, and offers narrower channel bandwidth modes for tighter spectrum.

Integration is built around reduced cabling. The antenna ports are two TNC female connectors, and power comes from a 9–32 V input or from USB power delivery. Input connectors provide Ethernet, USB and RS-232 for sensors and serial equipment, plus dual push-to-talk with independent left and right audio channels and a dedicated RoIP interface that bridges traditional land mobile radio systems into the mesh. A bi-color LED shows status. The anodized aluminum body weighs 182 g. It is offered as a rugged handheld unit powered externally or as a non-rugged OEM module, and StreamScape network management software is embedded for configuration and diagnostics.

The enclosure is rated IP68 and is specified for a wide operating temperature range. Data is protected with AES encryption, with the FIPS standard given in the encryption spec. Access to the Spectrum Dominance suite adds low probability of intercept and detection, anti-jam and interference avoidance capabilities, including a MANET spectrum analyzer; some functions are ITAR-controlled. Silvus notes that FCC authorization is required before sale or lease other than to the US Government or for export, so buyers should confirm approval status with the maker.

Typical uses include ground-force tactical communications, sharing video and sensor data across a team, and extending legacy radio networks into a digital mesh for defense, government and public safety agencies.
