Silvus Technologies has released a new software update to its StreamCaster radios, introducing enhanced electronic warfare (EW) defense features under the name Spectrum Dominance 2.0. The update is intended to improve the performance of Silvus’ mobile ad hoc networking (MANET) radios in contested and congested radio frequency environments.
The upgrade builds on the company’s existing MN-MIMO waveform by introducing two new capabilities: Wake on Wireless and Dual Frequency Link. These join a suite of existing features aimed at Low Probability of Intercept/Detection (LPI/LPD), anti-jam protection and threat mitigation.
According to the company, the new version is available via firmware update for existing StreamCaster AN/PRC-169 radios, enabling previously deployed systems to receive the enhancements without new hardware. The radios are used in handheld, vehicle-mounted and OEM-integrated configurations by U.S. and allied forces.
Silvus describes the update as a “layered EW defense” system, offering modular options that can be activated individually or as part of a broader spectrum defense configuration. This approach is designed to maintain secure, high-throughput communications during attempts to disrupt radio signals, such as jamming or spoofing.
While no operational or customer data was provided, the company emphasized that the release continues its focus on scalable, field-upgradable tactical communication systems capable of operating in high-threat environments.
Silvus is a U.S.-based company that develops tactical wireless communication systems, including mesh networking technologies used in military, public safety and industrial applications.
