There is no such thing as a packet collision... collisions take place at the media access/physical layers when two devices try to access the carrier at the same time..... and because the video is on a single, one way, point to point connections between the bird and the ground station, there can not be any collisions.
Uh hate to break it to you RB, but the description of WiFi and Lightbridge operations in the post is significantly flawed. Lightbridge is NOT a "broadcast" technology, it IS a unicast (point to point) data stream over WiFi using standard WIFi technologies (FHSS, ODFM, MIMO etc.). I don't know where this stuff comes from... WiFi doesn't use a handshake, neither does IP for every packet, and TCP doesn't resend video or audio segments when streaming data. He states, "WiFi hinders the goal of "real time" video, .." My my MacBook, AppleTV, iPad, and Samsung TV stream 1080P video with multichannel audio over WiFi using TCP/IP just fine without buffering or .... Reading any further in that post is pointless...
