    A Combined Technology for Wildfire Detection Using Hs/Rf
    (IEEE, 2009) Hanssen, Graeme; Sahin, Yasar Guneri
    This paper addresses an effective early detection system of wildfires using high resolution images from low-light sensitive cameras linked to an innovative HS/RF (High Speed/Radio Frequency) communications grid. Using data compression techniques, a data-stream and signal management application, combined with OFDM data transmission, the HS/RF enables broadband speed wireless communications. This obviates the need for expensive FO cabled infrastructure in remote locations, meaning the proposed system is relatively inexpensive to deploy. In terms of forestry management the HS/RF system exhibits dual advantages; because the video-stream provides real images on the ground there should be a reduction in false-alarms, and a reduction in the decisions-time to enable a rapid response. Systems processes and specialized hardware required to support operational details are also described.
