VideoLink Modem

Long-Range Video + Telemetry Modem for UAVs and Remote Systems

PLEASE NOTE:

**Windows operating system is required for the supporting software required to operate the VideoLink system.

The VideoLink Module is RFDesign’s latest innovation, combining our industry-proven long-range telemetry technology with low-latency video streaming in a compact, rugged, and integration-ready package. Designed specifically for UAVs, remote surveillance, and robotic applications, VideoLink enables operators to maintain visual situational awareness far beyond standard Wi-Fi or short-range links.

Tested under demanding conditions, VideoLink reliably transmits video and telemetry at ranges exceeding 5 km, depending on settings and antenna configuration. (Range tested using standard 3 dBi monopole antennas on both ground and air units. Higher ranges may be achievable with directional antennas or optimized configurations.)

A few points on the videolink system:

• The videolink desktop app which filters the video signal from the standard telemetry feed is currently a windows only software so will not be compatible with an RPi as the receiver.
• The videolink has only been tested with MAVLink formatted data so if you custom system is using another protocol that may not function correctly
• The Videolink uses increased frequency bandwidth and channel sizes for the high data rates which increase the potential for interference with other systems in the same band.
• Operating two pairs of modems is a complex undertaking that requires special consideration of antenna placement and modem settings for optimal performance and can still reduce maximum possible range and/or throughput.
• The RFD modem products are designed to operate safely without antennas attached. That said when in close proximity it is likely that even without antennas the signal leakage will still be such that it has the potential to interfere with other modems operating in the same frequency band.
