Silvus Technologies is a leading developer of wireless connectivity solutions for critical data and video transmissions. Our radio technologies provide enhanced throughput, interference mitigation, anti-jamming, and improved Quality of Service (QoS), making them ideal for the tactical applications of unmanned systems.
MIMO (Multiple-In Multiple-Out) is a breakthrough radio antenna technology in which packets are both transmitted and received on multiple antennas. This brings significant advantages in redundancy, multiplexing, and the ability to reconstruct a higher quality signal.
Our state-of-the-art MN-MIMO algorithm, featured in our radio products, blends MIMO with two other modern digital communications techniques – Coded Orthogonal Frequency Division Multiplexing (COFDM) for anti-interference, and Mobile Ad Hoc Networking (MANET) for robust mesh networking capabilities.
The result is a single frequency communications link with unprecedented throughput, range, and robustness that is ideal for the mission-critical video, C2, health, and telemetry transmission needs of unmanned vehicles.
Our StreamCaster™ radios represent the next generation of MN-MIMO technology, featuring Transmit (TX) Beamforming for increased range, Spatial Multiplexing for enhanced throughput, Space-Time Coding for enhanced robustness, and Receive (RX) Beamforming for enhanced reception.
Both the SC4200EP 2×2 MIMO radio and the SC4400E 4×4 MIMO radio are available in IP68 ruggedized form factors for reliable operation in harsh outdoor environments, or as an OEM package for embedding in custom products and subsystems. The powerful tactical radios feature up to 128 GB of onboard storage, ultra-low latency, AES256 encryption and adaptive data rates of up to 100 Mbps.
The SC4200EP (Enhanced Plus) 2×2 MIMO radio is a handheld unit designed for maximum portability and minimum SWaP footprint, with a total output power of up to 4W (8W effective with TX Beamforming) and battery life of up to 12 hours.
It is available in three different form factors: rugged externally powered, rugged handheld with twist-lock battery connector, and non-rugged OEM module.
The SC4400E (Enhanced) 4×4 MIMO radio has been designed to provide maximum range and power, with native transmit power of up to 8W (32W effective with Transmit Beamforming), and is ideal for long-range fixed-site, UAV and UGV applications.
It is available in three different form factors: rugged with straight RF connectors (for horizontal mounting), rugged with right-angled RF connectors (for vertical mounting), and non-rugged OEM module.

Unmanned Aerial Vehicles/Unmanned Aircraft Systems (UAVs/UAS) –
Our radios provide enhanced range and throughput for unmanned aircraft at ranges from pure LOS (line of sight) to extreme BVLOS (Beyond Visual Line of Sight). All communications are provided over a single frequency, resulting in high spectral efficiency.
Applications include ISR, relaying and range extension, swarming capabilities, battlefield data dissemination, and manned/unmanned teaming.
Unmanned Ground Vehicles (UGVs) –
Approved for use by QinetiQ in their TALON robots and MILREM, our radios have been extensively field tested in realistic mission scenarios and are highly suited to harsh urban environments with challenging terrain and obstacles.
