We already have people climbing roofs and mounting masts, as FSO improves it may be interesting and valuable to try such tech for P2P links. It would be quite possible to increase the speed on some point to point links already deployed.</div></div><div><br></div><div><u>Application to ForestNet</u></div><div><u><br></u></div><div>A 1Gpbs 30km link from Mt Moriac to Otways doesn't sound feasible with RF capabilities and regulations. Shorter links may be feasible, and use of FSO may be considered. </div><div><br></div><div>I only performed a quick search of current FSO capabilities. There may be better stuff out there.</div></div></div>
