Ship to ship communication by wireless LAN is expected to realize fast enough throughput in long range. In former field communication trial, omni-directional antennas were used and measured a few hundred kbps throughput between two ships, which was not enough to our research target. In order to get faster throughput, we carried out a series of field communication trials again with directional antennas. The trial was done by sailing a small boat along the heading line of a training ship moored to a pier, and measuring RSSI (Received Signal Strength Indication) and throughput between the ships. As a result, we confirmed 2-path model affected by the reflection of the sea surface, but the measured throughput was fast enough to our expectation.
