In the 802.11 protocol broadcast happens at minimum speeds (usually 1 Mbps) since there is no ACK system to know if the packet has been delivered successfully.
But I want to broadcast a video stream and higher error rates are not a problem for my application, and I would prefer higher speeds to lower error rates (I will handle the error correction on higher layers with my own codes).
I have set up an access point using "Hostapd" and a 802.11n wifi dongle in linux on a raspberry pi 2 and wanted to know if there is a way to change the broadcast speed limit so I can do the broadcast in higher speeds.
I tried removing the lower speeds in Hostapd by adding
supported_rates=240 360 480 540 basic_rates=240 360 480 540
But still broadcast is happening at 1Mbps.
