Hi, I was looking to sell the phantom 3 Advanced to buy a mavic mini and I wondered how worse the max distance and signal strength is on the mini since it works on wifi instead of lightbridge.

Hello and good day. Thank you for reaching out and for the inquiry. The DJI Mavic Mini has a maximum transmission distance of :

Model MR1SS5
5.8 GHz
FCC: 4000 m
SRRC: 2500 m
Remote control model MR1SS5 must be used with aircraft model MT1SS5.
Model MR1SD25
2.4 GHz
MIC: 2000 m
CE: 2000 m
5.8 GHz
CE: 500 m
Remote control model MR1SD25 must be used with aircraft model MT1SD25.

In addition the transmission latency of the DJI Mavic Mini is at 170-240 ms ( depending on environmental conditions and mobile device ). Thank you.
