The “Phantom 4 pro” has appeared in the FCCID database and normally, doing by DJI’s pas history, this means it will be announced very soon.
Not much is given away in the FCC details though. We know its model number WM331A, we know it looks like the same battery compartment.
One interesting bit of info is the frequency range the Phantom 4 Pro “can” operate at. DJI submitted a “Frequency Band Statement” to the FCC stating that the P4P can operate at 5150 MHz ~ 5250 MHz, 5250 MHz ~ 5350 MHz, 5470 MHz ~ 5725 MHz and 5725 MHz # 5850 MHz. They state that all other frequencies other than 5725 MHz # 5850 MHz will be disabled by firmware. This is the second FCC application from them I have seen specifically mention this. The other was the Mavic. This could possibly mean the P4P will use the Ocusync technology that the Mavic does.
