LUMA™ – the most compact, power efficient and infinitely programmable through-water wireless optical nodes for data transfer anywhere from the splash zones down to 6’000m depth.
LUMA is designed with flexibility in mind. In its base configuration it is a transparent link between your legacy systems, making it very easy to integrate. Plug&Play is not just marketing language when it comes to LUMA.
We call our LUMAs wireless communication nodes because they can be programmed to be used in a mesh network or even serve as access points for high-speed wifi coverage over a subsea field. AUVs, ROVs and infrastructure can then be wirelessly connected. This suddenly opens up affordable high-bandwidth subsea connectivity which was previously not possible.
LUMA will wirelessly transfer high volume of data in a variety of subsea applications during construction, inspection, monitoring and repairs in the offshore energy sector. In the science & research sector it will serve as a regular environmental data uplink from an ADCP, a camera or other sensors on the sea floor. We see other opportunties in the aquaculture and defense space.
With LUMA you can now design connectivity solutions all the way from the ocean floor at 6’000m to a satellite in the space. Splash zone communication is something that LUMA can deal with really well. In this way LUMA offers unparalleled connectivity and can be a vital agent for real-time monitoring of structures in digital twin systems.

No, all LUMA devices are transceivers and can send and receive data (half-duplex).
A number of configurable forward error correction schemes, which increase the reliability of the communication channel, are implemented. Faulty packages are automatically rejected on the receiving side using a checksum which is automatically added on the sending side. In order to maximize the transparency and versatility of the LUMA optical communication nodes, no additional protocol layers (such as TCP) which would ensure data delivery through resending, are implemented.
No, we currently do not implement an addressing scheme where each LUMA has an ID and only receives data which is specifically sent to that ID. Every modem within range receives data from a transmitting modem.
Yes, any light source can be a possible source of interference. The level of interference however strongly depends on the type and brightness of the light source. Typically, constant light sources (such as sunlight, incandescent lights) cause much less (if any) interference than pulsed light sources (dimmed LEDs, fluorescent tubes with an electronic ballast).
Yes, the ranges indicated in the data sheet are for clear water. An increased turbidity decreases the maximum range.
Not necessarily. While the maximum range indicated in the data sheet requires a direct line of sight, indirect light from reflective surfaces or scattered light from particles in the water will often allow for a communication link even without line-of-sight.
