Waterborne amphibious movement begins in an amphibious ship’s well deck. Once embarked on landing craft assault forces are isolated from the ship’s C2 assets. Communication during this stage of operations would benefit greatly from the use of wireless technologies; however, the radio frequency environment of well deck configurations presents significant challenges. This problem is compounded by constant changes in the geometry and reflective properties of objects in the space. This paper proposes a methodology for discovering optimized positioning of COTS 802.11ac wireless local area network devices in well deck spaces. The discovery begins with modeling and simulation using a 3D ray tracing engine in conjunction with CAD software to better understand the behavior of WLAN frequencies in these enclosed spaces. These data are then tested through experimentation in a steel shipping container designed to simulate conditions found in an enclosed shipboard space. Using the positions determined by these simulations in the worst propagation cases the data show that a WLAN based on the IEEE 802.11ac standard can be used to effectively and efficiently exchange data in this environment. The analytical study of WLAN performance under these austere conditions can be applied to any organization operating within highly reflective areas.
