AeroHive's answer to Ruckus's BeamFlex?

  • Question
  • Updated 4 months ago
During a recent Ashley Nurcombe webinar I asked about AeroHive's response to Ruckus's adaptive antenna (BeamFlex) and was told AeroHive Wave 2 APs already have a similar technology.
 I've been wanting to investigate this further but have not found any source material describing in depth what this technology is, what it does, or what results it gives. Can someone point me in the right direction?
 To clarify, I'm not talking about MIMO, or on-chip beamforming that are part of the 802.11 standards, but any extra technology (physical or software) that AeroHive are using to mitigate co-channel interference etc.
Thanks, Tim

Hi T, is it possible that Ashley mentioned the explicit beamforming that is part of the 802.11ac wave 2 standard?

My guess is that he was referring to the "Smart Antenna" feature, which is available for AP250 and AP550.

Support was added to NG in August 2017:

Smart Antenna Support

HiveManager NG now supports smart antennas. Smart antennas use advanced algorithms to determine and configure the best possible combination of active antenna array elements to ensure the best quality radio link between the smart antenna and the client device. You can choose to use the smart antenna feature when configuring the radio profile.

There is not much more information out there... check this video:

thanks for this. It's definitely the Smart antennas stuff I'm interested in. The video mentions per-client polarization, but I'm also wondering if the antenna array "focuses" the RF lobes, or reduces rear-ward lobes like Ruckus claim to do.
The blog has some RF lobe charts of directional antennas but these are fixed rather than per-packet/per-client dynamic beaming.
It was my understanding that the 802.11 beamforming is created by additive interference of two (or more?) antenna, which, while increasing signal at the intended client, doesn't really address signal strength at other clients for that unwanted packet.
Feel free to correct me :-)

I asked Ashley what he was referring to, and it was a combination of chipset beamforming and our smart antenna, as mentioned earlier (the Aerohive Champs are awesome).
