Wireless Digitization Telecommunication Application in the Forest-Fire Preventing

Communication of command and schedule is a very important aspect in forest-fire preventing application. And wireless interphone is now widely used in command and schedule. The intricate and costly relay equipments are constructed when the two communicators is far away. This paper proposes a new approach based on embedded system, which transforming voice signals to digital signals, achieving the long-range wireless interphone voice communication by adopting existed digital monitor and control network. This approach has lower costs and simpler equipment than the traditional approach
