1. A bi-directional asymmetric system, comprising:
- a first node with a first transmitter that produces a modulated magnetic flux and a first exciter receiver that acts to receive data at the first node; and
a second node coupled to the first node with a direct inductive communications downlink and a mutually inductive uplink, the second node including a receiver that produces a signal induced by the first transmitter at the first node, the second node having a mutually inductive data transmitter that modules an exciter signal produced at the first node by the exciter receiver.

Abstract
A bidirectional asymmetric system is provided with a first node and a second node. The first node has a first transmitter that produces a modulated magnetic flux and a first exciter receiver that acts to receive data at the first node. The second node is coupled to the first node with a direct inductive communications downlink and a mutually inductive uplink. The second node includes a receiver that produces a signal induced by the first transmitter at the first node. The second node has a mutually inductive data transmitter that modules an exciter signal produced at the first node by the exciter receiver.
