WiFi broadcast is a method to send data from A to B via WiFi without the need to establish a bidirectional link – like listening to a FM radio broadcast. It is used by drones to send digital video data without too much delay. 

WiFi broadcast uses the send/receive raw data option that some WiFi device and drivers can do. 

FEC is forward error correction - proactively send extra bits, to recover data from occuring bit errors at the receiving end. A technique widely used in communication systems like WiFi. Also used on digital media, like DVDs or CDs.

Unfortunately, using WiFi broadcast mode means implementing/handling FEC on your own.
