WiFI Broadcast

WiFi Broadcast has great potentials as link layer between the drone and the ground station. As well as link layer for video data created on the ground, e.g. between the speedboats and the mothership.

We tested the original WiFi broadcast implementation on a TL-WN722N with a patched driver. We did tests in the noisy Berlin environment and reached a throughput of 8 to 20 MBit/s.

There are various projects that use the WiFi broadcast code:

The original implementation doesn't care much about the transmitted data. You can pipe whatever data you have to the tx process. Some of the mentioned implementations provided MAVLink transport, others provide a UDP interface.

The code for injecting packets is quite simple and can be adapted to our needs, e.g. improved forward error correction.

* test in realistic environment, e.g. noiseless sea env * range test * test antenna combinations, e.g. dipol and sector, dipol and dish * implement tun/tap over wifibroadcast * …
