Silvus Technologies is a leading developer of wireless connectivity solutions for critical data and video transmissions. Our MIMO radio technologies provide enhanced throughput, interference mitigation, anti-jamming, and improved Quality of Service (QoS), making them ideal datalink solutions for the tactical applications of unmanned systems.
Next-Generation MN-MIMO Technology
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.
Wireless Connectivity for 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.
The SC4200EP 2×2, SC4400E 4×4 and SL4200 2×2 radios are available in IP67/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 20Mbps for the SL4200 and 100 Mbps for the SC4200EP and SC4400E.
The SC4200EP (Enhanced Plus) 2×2 is a handheld unit designed for maximum portability and minimum SWaP footprint, with a total output power of up to 10W (20W 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 has been designed to provide maximum range and power, with native transmit power of up to 20W (80W 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.
The SL4200 (Lite) 2×2 is a low-SWaP (size, weight and power), budget-friendly system utilising the same MN-MIMO waveform as the larger StreamCaster models, delivering a total output power of up to 1W (2W effective with TX Beamforming) in a compact footprint.
It is available in a rugged IP67-rated enclosure weighing less than 300 grams, or as a non-rugged OEM version weighing just 105 grams.
