Abstract
A technique enables wireless communication of signals in a well. The technique is employed for communication of power signals and/or data signals between a mother wellbore and at least one lateral wellbore. A first wireless device is positioned in a mother wellbore proximate a lateral wellbore, and a second wireless device is positioned in the lateral wellbore. The power and/or data signal is transferred wirelessly between the first and second wireless devices via magnetic fields. A plurality of the first and second wireless devices may be employed in cooperating pairs to enable communication between the mother wellbore and a plurality of lateral wellbores.
