Remote Controller with Built-in Screen
A 5.5in 1080p screen integrated with the Phantom 4 Pro + offers 1000 cd/m2 of brightness, more than twice as bright as conventional smart devices. As the DJI GO app is built into the screen, hardware and software can be fully optimized, allowing you to edit and share instantly. A five-hour battery life makes the Phantom 4 Pro + a complete aerial imaging solution. The integrated upgraded Lightbridge HD video transmission system supports dual frequencies for greater interference resistance and a maximum video transmission range of 4.3mi (7km)*.
 
NEW LIGHTBRIDGE VIDEO TRANSMISSION SYSTEM
The Phantom 4 Pro controller integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support. The ability to choose between 2.4GHz and 5.8GHz allows pilots to cut through interference and eliminates image lag caused when flying in an area with extensive 2.4GHz frequency use. Normally, Wi-Fi video transmission systems use a 2.4GHz frequency to work with a controller using a 5.8GHz frequency as this prevents interference that can occur when both use the same frequency. If using the same frequency the video transmission system and the remote controller will interfere with each other, causing image lag.

The Lightbridge HD video transmission system used in the Phantom 4 Pro uses TDM (Time Division Multiplexing) to transmit signals, allowing it to send controller signals and receive video transmission signals at the same frequency. When switched on, the Phantom 4 Pro evaluates local signal levels, automatically choosing the transmission frequency with the lowest level of interference. This ensures the optimum range of a maximum video transmission of 4.3mi (7km)*.
