Verification of Communication Characteristics for Utilization of Radio Communication Device in Undersea Exploration Equipment

Abstract

In order to proceed development of deep and wide ocean, utilization of underwater equipment is necessary. Especially, recent large task is how to deploy large number of the equipment at the same time, but price of the equipment inhibit realization of the deployment. In this paper, as a method to reduce the price of the equipment, facilitation of the UHF band communication method and its verification is proposed. From number of the experiments, it is indicated that design guideline of propagation channel material, shape, contact place. Also, behavior of the electromagnetic wave in the propagation channel when frequency is changed and propagation length expanding method is indicated.
