What would be nice to have is something along the lines of what Ubiquiti brought out! 16 LAN ports, with fiber input, that mounts on a tower. BUT, need it as a Mux unit, so all the LAN ports work individually, on any IP subnet. One base unit (rack mount in building), fiber up the tower, second remote unit (strapped on tower), that allows you to use any port for what is needed (POE output on tower). Have a separate DC wire feeding it !
That way you can feed backhauls, and AP's (from behind the router) via one fiber cable up the tower.
This would eliminate long cable problems, and RF induction on the cabling. Needed DC amperage to the tower unit would be handled by size of DC cable going up the tower. Unit could just use 50+ volts and then regulate down to 48 or 24 volts as needed on the POE output.
