You are behind Ben. I already admitted to that
There are a couple post I need to go back and read to make sure I am up to speed.
I did make the mod and tested checking WiFi channels and confirm that the band apparently is expanded both up and down. 802.11 channels 1 through 11 do stay in their same location on the DJI app at approximately 13-19.
I also made a couple test runs flying through two batteries this morning with no improvement in range. However, I think I am in a somewhat quiet WiFi environment compared to a lot of city dwellers and it would only be logical to think I would get less gains than others.
Still leaves me with a couple questions/comments.
- Since it appears this is going out of the traditional "free for all" WiFi band I would assume we are in FCC violation in the US and if DJI originally shipped the app this way they must have been too. That is a question... As I said there were a couple previous post with good info I need to read again.
- And finally I would assume that DJI has cut the antennas on the Phantom to be resonant in the middle of the band around channel 16/17. The antennas are going to become less efficient as you move off the resonant point so I would think there is a trade off in loss vs what you would gain from being on a cleaner channel. I mentioned this before but I saw a post on another forum where a member used an antenna analyzer on a 3DR product and to be honest if his numbers were correct I was surprised the amount of loss the antenna had just by going to the edge of the bands.
So if that is the case I don't think it's wise to automatically jump clear to one end of the spectrum.
Interesting mod for those with congested WiFi.
Kudos.
