Wireless optical OFDM implementation for aircraft cabin communication links

The state of development of optical devices has led to increased interest in high data rate wireless optical communication schemes that today constitute a viable alternative to conventional wireless technologies for information exchange. In this work, a high data rate wireless optical link, based on OFDM modulation, conventional laser diodes and large area photodiodes, was implemented and investigated. A laboratory prototype was used to demonstrate a data rate of 19.6Mbit/s. A 64-subcarrier OFDM signal with different subcarrier modulation schemes (BPSK, QPSK) was examined. Target applications are video, high speed internet etc. within the confines of an intra-cabin wireless optical topology
