categories - AC_BE , AC_BK, AC_VI and AC_VO for WMM.

supported by Wi-Fi networks. It allows devices to take more time in sleeping state and
consume less power to improve the performance by minimizing transmission latency. Such
function is designed for mobile and cordless phones that support VoIP mostly.
