Hoping for soon. My max distance with WIFI(and controller) is 3000 feet (or 1000 meters). From the DJI website for the spark "FCC: 1.2 mi (2 km)" I'd be happy with just 1 mile if I could get it. Also I'm trying to understand this.
If you are using the controller, isn't the wifi ONLY connecting to the controller? If so why does the OTG cable help with distance? Doesn't the controller talk to the drone and the controller talk to the phone at the same time? I can see the video signal possibly being better just because of a physical cable and not sending over wifi...but I don't understand a longer drone distance. Can someone help me understand this?
Sorry for the greatly delayed reply. But I just bought mine yesterday.
Wifi has a set bandwidth to be shared amongst all the appliances. If for example your Wifi hasa capability of 5MB/s and the video for the Phone is using 2MB the Spark only has 3MB availiable. And the bandwidth gets choked by distance, it will go down pretty linearly, barring metal and significant barriers.
and WIFI devices next to each other interfere with the signal. making the distance even shorter. so it is a gain gain gain. for the OTG cable.
