Rts/cts

[mmpg]

I wanted to know that whether the RTS/CTS frames used in 802.11 A MAC layer are broadcast frames or unicast frames.

[JimGeier]

Both RTS and CTS frames are sent as unicast frames. The receiver address of a RTS frame is the address of the station where the source station wants to send either a data or management frame. The station receiving the RTS will copy the transmiter address from the RTS frame for use as the receiver address within the CTS frame. You can view one of my tutorials on RTS/CTS at the following URL: http://www.80211-planet.com/tutorials/article/0,4000,10724_1445641,00.html

I hope that helps.
