DJI has redefined the drone racing industry with the new Digital FPV System. It delivers lower latency rates within 28 ms, a 4km maximum transmission range, stunning HD 720p/120fps resolution, and, most importantly, an unforgettable FPV flying experience.
 4km maximum transmission distance; FCC: 4 km, CE: 0.7 km, SRRC: 4 km.  Latency rate under 28ms at 720p/120fps and under 40ms at 720p/60fps.  There are up to eight channels for DJI FPV Goggles depending on the region (FCC: 8, CE/SRRC: 4, MIC: 3). Each channel has a bandwidth of 20 MHz. The default channel is eight and only one pilot at a time is allowed to use this channel. Forgetting to change this channel can affect your connectivity when operating the FPV Air Unit. Channel eight can be changed manually to avoid interference from other devices. All channels operate under a 5.8GHz frequency.  The DJI FPV Air Unit can also record in 720p/60fps and 720p/120fps (without audio).  7ms low latency between the DJI FPV RC and DJI FPV Air Unit can only be achieved under ideal conditions. Latency rates are not consistent.  4-in-1 closed-loop software for the DJI FPV RC reduces operational errors and allows users to change settings remotely.  Users must remove the microSD card from their DJI FPV Air Unit and insert it in their DJI FPV Goggles to watch recorded videos.  Omnidirectional antennas are only compatible with other antennas that are left-hand circular polarized.  Custom-made myopia lenses are only compatible with DJI FPV Goggles and will be sold at the DJI Store.  Unobstructed and free of interference when FCC compliant. Maximum flight range specification is a proxy for radio link strength and resilience.  The end-to-end latency is the total time from camera input to screen display. DJI FPV Goggles can reach their maximum transmission distance (FCC) in a wide-open area with no electromagnetic interference, achieving minimum latency in Low Latency mode (720p/120fps).
