How to interpret 802.11ac datarates
The data rate display format employed for 802.11ac is,
X = mcs (modulation coding scheme) 0-9Y = No of spatial streams, 1-3.Z = Bandwidth 2, 4, 8 (2 = 20Mhz, 4=40Mhz, 8=80Mhz)c = b for Beamform, s for STBC, - nones = Guard Interval, indicates Short guard interval applicable over LGI (Long guard interval)
X = mcs 1Y = 1 (Single spatial stream)- = Nodifferentiation for beamform/stbcZ = 2 (20 Mhz wide)
X = mcs9Y = 1 (Single spatial stream)- = No diffrentiation for bf/stbcZ = 4 (40 Mhz wide)
