1. A wireless transmission system for a multi-stage completion, comprising:
a surface power and telemetry system;
an upper completion comprising a casing, a production tubing disposed within the casing, and a tubing hanger supporting the production tubing, wherein the tubing hanger has a first portion, a second portion, and an insulating gap between the first portion and the second portion;
a lower completion comprising a production liner, a liner hanger disposed within the casing and supporting the production liner, a coupler, and one or more downhole devices;
a first cable extending from the surface power and telemetry system to the first portion of the tubing hanger;
a second cable extending from the coupler to the one or more downhole devices; and
a third cable extending from the second portion of the tubing hanger to the surface power and telemetry system;
wherein in use, power and telemetry signals flow from the surface power and telemetry system along the first cable to the first portion of the tubing hanger, then along the production tubing downhole to the coupler, the power and telemetry signals flow from the coupler along the second cable to the one or more downhole devices, and return telemetry signals flow from the lower completion along the casing to the second portion of the tubing hanger and then along the third cable to the surface power and telemetry system.
