Suppose a NIC wants to decrease TX power for certain rates based on the number of chains (ie, subtract amount A from requested rate for 2 chains, and B for 3 chains).
I assume the NIC wants to do this is because if the pkt is transmitted out each antenna, then there is ~3x the power put onto the air. Now, the question is, should this power-decrease be per rate, and perhaps different for each rate, or can all rates use all tx-chains (and so tx-power should be decreased the same maximum amount based on the hardware's number of chains for each rate). I am thinking that CCK rates can only ever be transmitted by a single chain, so in that case those rates would not need their power decreased from the requested? And if that is so, what about the /a/g/ rates, and lower-speed HT/VHT rates as well? Is there a table somewhere that explains how many chains are used by each rate?
