**Q: What is a difference from original wifibroadcast?**

**A:** Original version of wifibroadcast uses a byte-stream as input and splits it to packets of fixed size (1024 by default). If radio packets were lost and this is not corrected by FEC you'll got a hole at random (unexpected) place of stream. This is especially bad if data protocol is not resistant to (was not desired for) such random erasures. So i've rewritten it to use UDP as data source and pack one source UDP packet into one radio packet. Radio packets now have variable size depending on payload size. This reduces video latency a lot.

## Theory
WFB-NG puts the wifi cards into monitor mode. This mode allows to send and receive arbitrary packets without association and waiting for ACK packets.
