1. A method of supporting inductive communications among multiple transceivers, the method comprising:
- sharing a wireless bandwidth to sunnort bidirectional communications between pairs selected from at least three transceivers, the at least three transceivers including a base transceiver and at least two remote transceivers with which the base transceiver communicates, the at least two remote transceivers being assigned use of one or more time slots to communicate within a communication cycle;
disposing at least two transducer elements in the base transceiver and at least one transducer element in each of the at least two remote transceivers to support inductive communications between the transceivers at any angular orientation relative to each other within a range of distance;
comparing link qualities of communications between different transmit-receive transducer elements for each remote transceiver communicating with the base transceiver;
selecting transmit-receive pairs of transducer elements to support further communications in respective time slots between the base transceiver and the at least two remote transceivers based on detected link quality;
generating a signal from a selected transducer element of the at least two transducer elements in the base transceiver; and
simultaneously receiving the signal on the at least two remote transceivers to compare link qualities of different transducer element pairs.

Abstract
Contents of one or more received messages can be analyzed to determine whether a transceiver device generating the inductive field has already been programmed with a unique communication code. If not, bidirectional communications can be established to program the transceiver device with a unique communication code over an inductive link. Orientation or position of a transceiver device can be used to initiate a process for programming a communication code. Generally, the communication code can define a unique relationship between two or more transceiver devices.
