To DS and From DS bits in the Frame Control Field

[girig]

Hi All,

I am a new member registered in this forum expecting help from all of you in understanding the 802.11 standard better.

My doubt:

1. Does the Stations have knowledge about the Distribution
System the AP is connected to ?

2. are the FromDS and ToDS bits in the Frame Control Field of the
802.11 MAC header of data frames, set/reset only by the AP or
even by the Stations ?

Thanks for your time,

regards

the wireless NIC need not know abt DS.
from/to DS field is set by the tx, both AP and NIC.

A good way to conform ur queries is to have and AP and NIC talk and sniff the wireless packets.
