From NetGear.com --- "The range is lower in the 5 GHz band because higher (5 Ghz) frequencies cannot penetrate solid objects, such as walls and floors. "
I would tend to agree [USER=1188]@Seitenwerk[/USER] - but only if you have obstacles in between you and the drone such as trees or buildings, etc. But from what I've read, the 5 Ghz transmission distance will be fine as long as there are no obstacles in the way. And if you use 2.4 Ghz, the interference will affect the range. So, considering that 5 Ghz is less crowded, I suspect there will be no appreciable difference in range as long as there are no obstacles. I just flew the Anafi using 5 Ghz and the video transmission was great and I had no transmission failures at all.
