In this article, we propose a disaster communication system using ad-hoc network and mesh network. In this system, we use the Etherphone which is new communication technology using only the data link layer and the physical layer. The Etherphone network uses a broadcast for the transmission of a message of data. We produced mobile communication terminal equipment by using Etherphone. We built an alternative communication network at the time of disaster by constructing mobile ad-hoc network which using wireless multi-hop communication. We demonstrated that the mobile communication terminal equipment can take ad-hoc communication in alternative communication network at the time of disaster.
