Capacity of optical wireless communication channels

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020
Optical wireless communications are realized by modulating the intensity of a light source and detecting intensity fluctuations at the receiver. This mode of operation, known as intensity modulation and direct detection (IM/DD), is simple to implement in practice.

Indoor wireless optical communications

2010 8th International Conference on Communications, 2010
Indoor wireless optical communications (IWOC) can offer in certain applications a valuable alternative to wireless radio. Its main advantages being: low cost, medical safety and unlicensed band- width. The most suitable band- width seems to be 1550nm because of low noise and WDM solutions accessible by the current technology.
