Nowadays, most of pilot audio headsets inside aircraft cockpit are connected
with wires to the access point station. However, a wireless connectivity for headsets
constitutes an advantage in terms of comfort and offers flexibility to the pilots. The most
dominant wireless technology is based on radio-frequencies spectrum and presents some
drawbacks in the context of aeronautics, especially regarding security and reliability due to
interferences with other electronics equipment. We study in this article an alternative
communication system for pilot headsets, based on optical wireless technology. Optical
rays have the advantage of being confined into the cockpit and not interfering with
radiofrequencies. From optical channel model in the cockpit, we evaluate the potentiality of
optical wireless links in terms of communication reliability. |
