In this paper, we discuss a communication system for disaster relief medical teams. Usually, Japanese medical teams are not equipped with communication systems specialized for disaster operations. They can only rely on common-use mobile and landline phones during disaster events. However, public lines are reported to be out of function in disaster areas during the past major disasters. We conducted experiments to evaluate communication means that can holdmedical communication links during disasters, using the new Japanese two-way communication radio system,“Digital Convenience Radio: DCR”. Our results suggested that DCR can support medical activity at sites ofdevastating disasters.
