Abstract
The present disclosure describes methods and systems that can be used for controlling and coordinating the transmission of electromagnetic telemetry signals from and/or to a plurality of downhole tools to minimize or reduce electromagnetic interference between the transmissions. Signal coordination control is also disclosed that allows for duplex bidirectional communication of transmissions of electromagnetic telemetry signals such that electromagnetic interference between the transmissions is minimized or reduced.
