Why is TxBF limited to the R710?
I recently got an R710, and in playing around with it, I've noticed that some of my devices are using a MCS rate that includes "/2/BF", which seems like it's using 4 radio chains to do 2-stream TxBF in addition to BeamFlex? Very cool :)
I also noticed that the support info for the R710 on 9.12 shows a lot of info about TxBF sounding frames and such, which is missing from the R600/R700. Is there a particular reason that the R710 supports TxBF but the R600/R700 does not?
FWIW, I'm also noticing that the R710 is able to deliver good 802.11ac speeds to Wave 1 devices at a longer range. Even through 2 walls, I'm seeing 300mbit on a 3x3:3 Wave 1 client when an R600 just a few feet away can only deliver 400-450mbit to the same client. Looks like it's a compelling upgrade even if you don't have Wave 2 capable clients!
