hi Dale42110 where are you situated if you are in the states you will get the range as stated by DJI if you are in the UK you will get considerably less range this is due to the signal power of the remote controller, and it is set according to the radio transmitter laws of the country you are in.the main advantages of ocusync are not so much the range, but the stable signal you get compared to normal WIFI as on the ph3 that you have.
