Abstract
A downhole communication system includes a gap sub located at an RSS. The gap sub is located on the outer, independently rotating member of the RSS. This allows the RSS to receive electromagnetic downlink communication signals from the surface or from an MWD. The RSS transmits electromagnetic uplink signals to a second gap sub located above the RSS or to the surface.
