Abstract
A method and system for facilitating location of a wireless communication device communicating via a communication path that includes a fiber optic cable is disclosed. The delay associated with a communication propagating through a fiber optic cable can be used to more accurately determine inputs used when locating a device using triangulation. The delay introduced by the cable may vary with the temperature of the cable. Therefore, the temperature associated with the cable is measured and used to determine a delay associated with the fiber optic cable. An indicator of the delay may then be used by a positioning system to more accurately locate a wireless communication device.
