- 3G Radio Field Intensity Measurement Experiment in Coastal Waters of Tokyo
抄録
A small vessel like a fishing vessels and pleasure boats account most of the marine accidents with the fatality or missing person in these five years. For preventing such a marine accidents, it is important to make a contact immediately to stop such accident. Current major way of accident notification is by using AIS or Satellite communication based system. Although these ways are useful for marine accident detecting, it is not mandatory to equip those systems to a small vessel. Furthermore, current systems are expensive for a small vessel.<br>In this study, we focused on that 3G radio communication having possibilities to be available in coastal waters of Tokyo, measured 3G radio field intensity by developed measurement system in Tokyo Bay and Uraga Channel. From the results of the measurement experiment, we showed the 3G radio can receive on the sea of around 5km from the land and near the sea surface. The realization of new marine accidents prevention system can be expected by utilizing the 3G communications in coastal waters of Japan We described the design of the system that takes into account the characteristics of 3G communications on the sea.
