About 802.11 broadcast frames

Hi community,

 

Do you know how broadcast frames are handled in Wi-Fi? I have been googling but the information I have found in several sites is contradictory. This is some sentences I have found about when an AP sends a broadcast frame:

 

  • Broadcast frames are converted to unicast and sent independently to every single station associated with the AP.
  • Broadcast frames are sent as usual and every station is able to understand them.
  • Broadcast frames are acknowledged by every station.
  • Broadcast frames do not need to be acknowleged.

Do you know what of these senteces are true? Or does the behaviour depends on the vendor?

Well, after browsing at this book and others, I can conclude that broadcast frames are sent as usual (not converted to unicast) and every station will hear them. In addition, these broadcast frames do not need to be acknowledged.
