1. A wireless initiation device, including:
a housing, a processor disposed within the housing and configured to process wireless electromagnetic communications signals including a wireless electromagnetic communications signal representative of a FIRE command, the processor configured to generate an initiation signal upon receipt of the FIRE command; and
a circuit configured to discharge initiation energy sufficient to initiate an explosive charge associated with the wireless initiation device, the circuit configured to be communicatively coupled to the processor such that the circuit can receive the initiation signal from the processor that results in the discharge of the initiation energy,
wherein the processor is configured for wireless electronic data exchange with an encoder configured to transmit programming data wirelessly to the wireless initiation device,
wherein the programming data include a delay period for the wireless initiation device, and/or wherein programming of a delay period occurs by transmission of one or more wireless electromagnetic communications signals that are receivable by an antenna disposed within the housing, and
wherein the delay period has been determined for the particular wireless initiation device in a blast pattern.
