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.

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.
