Abstract
Optical fiber-based distributed communications components and systems, and related methods to provide localization services for client devices are disclosed. The localization services allow the providing and/or determination of the location of client devices in communication with a component or components of the optical fiber-based distributed communications system. The location of client devices can be provided and/or determined based on knowledge of the location of the component or components in the optical fiber-based distributed communications system in communication with the client device. This information can be used to determine or provide a more precise area of location or area of location for client devices. The optical fiber-based distributed communications components and systems, and related methods disclosed herein may be well-suited for indoor environments where other methods of providing and/or determining location of client devices may be obstructed or not possible due to the indoor environment.
