In the series of our research works, the authors have been working on the support of fishing industry by using information and communication technologies. In this paper, we report on a wireless network namely "Marine Broadband Framework" constructed aiming at the improvement of an intelligent productivity and safety in the coastal region. Marine broadband framework is a wireless network of which the transmission rate is considerably as much as ADSL and it can be successfully applied to small fishing vessels operating in the coastal regions. The construction of marine broadband framework by using wireless LAN system of the IEEE802.11j standard, and the experiment of coverage in the Wakkanai coast had been carried out. In this experiment, we confirmed the marine broadband framework can be used within the range of about 14km from the base station that had installed on the coastline. Moreover, the operation of marine broadband framework intended for a small fishing vessel has begun in the Rumoi coast since July, 2008. In the range of about 3km, the actual throughput of 10Mbps and more is recorded. Experimental results show that a wireless network is applicable in the coastal region effectively as much as ADSL.
