Abstract

We have been developing an information system for supporting fire-fighting activities.This system can collect and transmit immediately actual disaster information to headquarters,and transmit the useful information to fire brigades in a large-scale disaster.Wireless LAN and FiReCos;that we developed are installed in this information system as a unique communication network.For making practicable,we constructed a network with several wireless LAN units and carried out field communication tests.The conclusions are as follows;(1)Voice and data communication can be done via six wireless LAN units.(2)Spanning tree technology can evade network trouble in a network constructed with wireless LAN units.(3)A roaming of FH type wireless LAN is effective in radio communication.
