The majority of commercial quadcopters use Wi-Fi for remote control and suffer from a fairly limited range. This simple hack uses an Wi-Fi router as an extender to radically expand the range of your copter.
There’s no heavy modification or code tweaking required, all you need is a power source for the router and the ability to set it up as a repeater. The extra signal boost provided by the repeater extends the range from an average of 50 meters to over 250 meters. Check out the video above to see it in action.
