Local Traffic Generator (LTG) data rate

Hi,

In the wlan_exp framework Local Traffic Generator (LTG), when I changed 'mcs'(to '1', '2', '3') and 'phy_mode'(to 'HTMF', 'NONHT'), I could get LLC data rate '9', '11', '13', '18', '19.5', '26' Mbps.

What do six values mean? Can I get different data rates using 'mcs' and 'phy_mod' in LTG ??

Thank you.

Re: Local Traffic Generator (LTG) data rate

The underlying PHY rate is described by the tuple of PHY_MODE and MCS.

For NONHT PHY_MODE (802.11a/g), the MCS values correspond to the following PHY rates:

MCS 0 : 6 Mbps
MCS 1 : 9 Mbps
MCS 2 : 12 Mbps
MCS 3 : 18 Mbps
MCS 4 : 24 Mbps
MCS 5 : 36 Mbps
MCS 6 : 48 Mbps
MCS 7 : 54 Mbps


For HTMF PHY_MODE (802.11n), the MCS values correspond to the following PHY rates:

MCS 0 : 6.5 Mbps
MCS 1 : 13 Mbps
MCS 2 : 19.5 Mbps
MCS 3 : 26 Mbps
MCS 4 : 39 Mbps
MCS 5 : 52 Mbps
MCS 6 : 58.5 Mbps
MCS 7 : 65 Mbps
