Definition of "Optical Wireless" |
Optical wireless refers to the combined use of two technologies - conventional radio-frequency (RF) wireless and optical fiber - for telecommunication. Long-range links are provided by optical fiber (also known as fiber optic cables), and links from the long-range end-points to end users are accomplished by RF wireless. Sometimes the local links are provided by laser systems, also known as free-space optics (FSO), rather than by RF wireless. |
