[QUOTE="stanleyy, post: 1504, member: 84"] Both Spark and Mavic do run on the same frequency bands, 2.4 and 5 GHz, and therefore the same power regulations are applied on both. This doesn't really explain the range difference between Mavic and Spark. Also I am almost 100% sure that Spark does not use Wifi or any similar protocol for 'full range' control via remote controller. That would not work, due to various reasons, related to band sharing, beacons and certification requirements. They must be using a proprietary protocol, just like on Mavic. Maybe with different modulation, but upper layers including video encoding are for sure very similar to those used on Mavic and other high end DJI products. I believe DJI has crippled the range on purpose to not compete with their other products, there is no reason for such drastic range reduction unless they have some EMC issues or antenna problems (which would not be surprising on such small device) I am not saying that 500 meters is a bad value for this type of drone, but I would prefer to have a bigger safe margin there.
