StreamCaster Radios Enable Robust Network Communications Between Air and Ground Assets

Be confident with communications linking in-building, command post, mission aircraft, HQ, and everywhere in-between

For decades, Frequency Modulated (FM) analog downlink systems were used to transmit video from cameras mounted on aircraft for live viewing on the ground. These FM downlinks provided broadcast quality video with near-zero latency in pure line-of-sight (LOS) conditions, but suffered color shifting and distortion in non-LOS conditions or in areas with a high degree of multipath.

In recent years, Coded Orthogonal Frequency Division Multiplexing (COFDM) has become the technology of choice for video downlink applications. Compared to FM systems, COFDM provides greater range in LOS conditions, and more robustness in the presence of multipath. COFDM can even operate in some non-LOS environments, thanks to the use of multiple RF carriers, powerful Forward Error Correction (FEC), and Maximal Ratio Combining (MRC). And with the implementation of new encoding techniques such as H.264, it became possible to use COFDM video links for the transmission of HD video.

Silvus Technologies has taken COFDM downlink technology to the next level with the incorporation of advanced Multiple Input Multiple Output (MIMO) antenna techniques and a flexible and robust mesh networking layer. Now, downlink video can be combined with high-speed uplink/downlink data in a single frequency bi-directional or mesh communications system. Silvus' proprietary MN-MIMO technology provides a reliable, hi-throughput connection between the aircraft and assets on the ground, opening the door for a number of next-generation applications.

Silvus StreamCaster™ radios provide the vital link between all your assets, from in-building, to command post, to mission aircraft, to HQ, and everywhere in between. Silvus ensures your entire team is on the same page when moments count.
