Why BlueComm 100 is perfect for your operations

For energy

BlueComm is an enabling technology for resident vehicles allowing high speed data off loading and low latency vehicle control.

For defence

AUVs or submarines can collect data fast and efficiently from seabed data-logging instruments and covertly harvest the data.

For science

With such fast data rates, it’s possible to ‘connect’ your subsea data back to your laboratory – without the costs of a cabled observatory.


BlueComm 100 uses an array of high power light-emitting diodes (LEDs) that are rapidly modulated to transmit data. The receiver uses photodiodes allowing peak performance in all lighting conditions, including very shallow ‘high ambient light’ conditions.

Both the receivers and emitters are packaged into a small 5 kg unit rated to 4,000 m. Delivering 5 Mbps at 15 metres range, BlueComm 100 is a short-range, highly reliable solution.

High-speed wireless communications are not just useful for controlling ROVs and AUVs. Wherever there is a subsea application requiring control, monitoring or the point-to-point transmission of data, ‘going wireless’ is now a credible alternative. BlueComm can be used to provide a remote ‘eyeball’ on specific subsea operations removing the need for a second ROV.

Complementary acoustic positioning and communications provide long-range command and control of the camera and optical link including wake-up, pan, tilt, zoom, lighting and sleep mode control functions.

As a high-speed communication platform, BlueComm is an Ethernet-connected device allowing plug-and-play connectivity to clients’ own subsea networks. As such, this allows for easy expansion of pre-existing networks, increasing productivity by increasing speed.

Its flexible system architecture means that BlueComm can be integrated with our comprehensive array of acoustic navigation, control and monitoring devices. Complementary Sonardyne acoustics communications provide long-range (>4 km), low bandwidth command and control. This capability enables functions such as data recording to be turned ‘on’ and ‘off’ remotely from the surface, and health or QC information to be transmitted.
