Detailed Description

AMRR Rate control algorithm

This class implements the AMRR rate control algorithm which was initially described in IEEE 802.11 Rate Adaptation: A Practical Approach, by M.


Lacage, M.H. Manshaei, and T. Turletti.

This RAA does not support HT, VHT nor HE modes and will error exit if the user tries to configure this RAA with a Wi-Fi MAC that has VhtSupported, HtSupported or HeSupported set.
