With the advancements and proliferation of wireless voice and data communications, there is a logical extension of these technologies to machinery monitoring and control systems. Typically, data communications occur over twisted pairs or fiber optic media. In a highly automated ship for reduced manning goals, the infrastructure to support these automation schemes may be difficult to implement given the survivability requirements. A WLAN with 802.11 technology provides redundant, 100% connectivity needed to support ship-wide device-level networking. However, under emergency conditions, such as a weapons strike, fire, or flooding, some portions of the network may become unusable, isolated, or destroyed. Backup means of providing wireless connectivity across bulkheads is needed. This backup connectivity could provide for re-establishment of communication between device level control components in the damaged area and the ship's control and monitoring networks, as well as establish voice communication between damage control personnel inside the compartment and the rest of the ship. . This SBIR response proposes the evaluation of two methods of through bulkhead communication that could be integrated with wireless technology. One option uses a piezoelectric device, mounted on each side of a bulkhead, to provide a coupling across the bulkhead. Another approach develops a hybrid wireless / power line carrier communication system.
