Abstract
Methods and related apparatus pertaining to downhole and surface telemetry, such as a method in which a telemetry system is provided with a communication path formed with an electrically conductive transport medium coupled across a plurality of downhole nodes. Such method includes operating on the communication path with a multi-drop system that provides telemetry to the downhole nodes in a wellbore, including employing modulation in a master-slave arrangement using binary differential phase shift keying or differential quadrature phase shift keying.
